## Migration Guide from v2 -> v3
Version 3 adds several new, frequently requested features. To do so, it introduces a few breaking changes. We've worked to keep these as minimal as possible. This guide explains the breaking changes and how you can quickly update your code.
### `Token.Claims` is now an interface type
The most requested feature from the 2.0 verison of this library was the ability to provide a custom type to the JSON parser for claims. This was implemented by introducing a new interface, `Claims`, to replace `map[string]interface{}`. We also included two concrete implementations of `Claims`: `MapClaims` and `StandardClaims`.
`MapClaims` is an alias for `map[string]interface{}` with built in validation behavior. It is the default claims type when using `Parse`. The usage is unchanged except you must type cast the claims property.
The old example for parsing a token looked like this..
```go
if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
}
```
is now directly mapped to...
```go
if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
claims := token.Claims.(jwt.MapClaims)
fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"])
}
```
`StandardClaims` is designed to be embedded in your custom type. You can supply a custom claims type with the new `ParseWithClaims` function. Here's an example of using a custom claims type.
```go
type MyCustomClaims struct {
User string
*StandardClaims
}
if token, err := jwt.ParseWithClaims(tokenString, &MyCustomClaims{}, keyLookupFunc); err == nil {
claims := token.Claims.(*MyCustomClaims)
fmt.Printf("Token for user %v expires %v", claims.User, claims.StandardClaims.ExpiresAt)
}
```
### `ParseFromRequest` has been moved
To keep this library focused on the tokens without becoming overburdened with complex request processing logic, `ParseFromRequest` and its new companion `ParseFromRequestWithClaims` have been moved to a subpackage, `request`. The method signatues have also been augmented to receive a new argument: `Extractor`.
`Extractors` do the work of picking the token string out of a request. The interface is simple and composable.
This simple parsing example:
```go
if token, err := jwt.ParseFromRequest(tokenString, req, keyLookupFunc); err == nil {
fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
}
```
is directly mapped to:
```go
if token, err := request.ParseFromRequest(req, request.OAuth2Extractor, keyLookupFunc); err == nil {
claims := token.Claims.(jwt.MapClaims)
fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"])
}
```
There are several concrete `Extractor` types provided for your convenience:
* `HeaderExtractor` will search a list of headers until one contains content.
* `ArgumentExtractor` will search a list of keys in request query and form arguments until one contains content.
* `MultiExtractor` will try a list of `Extractors` in order until one returns content.
* `AuthorizationHeaderExtractor` will look in the `Authorization` header for a `Bearer` token.
* `OAuth2Extractor` searches the places an OAuth2 token would be specified (per the spec): `Authorization` header and `access_token` argument
* `PostExtractionFilter` wraps an `Extractor`, allowing you to process the content before it's parsed. A simple example is stripping the `Bearer ` text from a header
### RSA signing methods no longer accept `[]byte` keys
Due to a [critical vulnerability](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/), we've decided the convenience of accepting `[]byte` instead of `rsa.PublicKey` or `rsa.PrivateKey` isn't worth the risk of misuse.
To replace this behavior, we've added two helper methods: `ParseRSAPrivateKeyFromPEM(key []byte) (*rsa.PrivateKey, error)` and `ParseRSAPublicKeyFromPEM(key []byte) (*rsa.PublicKey, error)`. These are just simple helpers for unpacking PEM encoded PKCS1 and PKCS8 keys. If your keys are encoded any other way, all you need to do is convert them to the `crypto/rsa` package's types.
```go
func keyLookupFunc(*Token) (interface{}, error) {
// Don't forget to validate the alg is what you expect:
if _, ok := token.Method.(*jwt.SigningMethodRSA); !ok {
return nil, fmt.Errorf("Unexpected signing method: %v", token.Header["alg"])
}
// Look up key
key, err := lookupPublicKey(token.Header["kid"])
if err != nil {
return nil, err
}
// Unpack key from PEM encoded PKCS8
return jwt.ParseRSAPublicKeyFromPEM(key)
}
```

# jwt-go
[![Build Status](https://travis-ci.org/dgrijalva/jwt-go.svg?branch=master)](https://travis-ci.org/dgrijalva/jwt-go)
[![GoDoc](https://godoc.org/github.com/dgrijalva/jwt-go?status.svg)](https://godoc.org/github.com/dgrijalva/jwt-go)
A [go](http://www.golang.org) (or 'golang' for search engine friendliness) implementation of [JSON Web Tokens](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html)
**NEW VERSION COMING:** There have been a lot of improvements suggested since the version 3.0.0 released in 2016. I'm working now on cutting two different releases: 3.2.0 will contain any non-breaking changes or enhancements. 4.0.0 will follow shortly which will include breaking changes. See the 4.0.0 milestone to get an idea of what's coming. If you have other ideas, or would like to participate in 4.0.0, now's the time. If you depend on this library and don't want to be interrupted, I recommend you use your dependency mangement tool to pin to version 3.
**SECURITY NOTICE:** Some older versions of Go have a security issue in the cryotp/elliptic. Recommendation is to upgrade to at least 1.8.3. See issue #216 for more detail.
**SECURITY NOTICE:** It's important that you [validate the `alg` presented is what you expect](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/). This library attempts to make it easy to do the right thing by requiring key types match the expected alg, but you should take the extra step to verify it in your usage. See the examples provided.
## What the heck is a JWT?
JWT.io has [a great introduction](https://jwt.io/introduction) to JSON Web Tokens.
In short, it's a signed JSON object that does something useful (for example, authentication). It's commonly used for `Bearer` tokens in Oauth 2. A token is made of three parts, separated by `.`'s. The first two parts are JSON objects, that have been [base64url](http://tools.ietf.org/html/rfc4648) encoded. The last part is the signature, encoded the same way.
The first part is called the header. It contains the necessary information for verifying the last part, the signature. For example, which encryption method was used for signing and what key was used.
The part in the middle is the interesting bit. It's called the Claims and contains the actual stuff you care about. Refer to [the RFC](http://self-issued.info/docs/draft-jones-json-web-token.html) for information about reserved keys and the proper way to add your own.
## What's in the box?
This library supports the parsing and verification as well as the generation and signing of JWTs. Current supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own.
## Examples
See [the project documentation](https://godoc.org/github.com/dgrijalva/jwt-go) for examples of usage:
* [Simple example of parsing and validating a token](https://godoc.org/github.com/dgrijalva/jwt-go#example-Parse--Hmac)
* [Simple example of building and signing a token](https://godoc.org/github.com/dgrijalva/jwt-go#example-New--Hmac)
* [Directory of Examples](https://godoc.org/github.com/dgrijalva/jwt-go#pkg-examples)
## Extensions
This library publishes all the necessary components for adding your own signing methods. Simply implement the `SigningMethod` interface and register a factory method using `RegisterSigningMethod`.
Here's an example of an extension that integrates with the Google App Engine signing tools: https://github.com/someone1/gcp-jwt-go
## Compliance
This library was last reviewed to comply with [RTF 7519](http://www.rfc-editor.org/info/rfc7519) dated May 2015 with a few notable differences:
* In order to protect against accidental use of [Unsecured JWTs](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#UnsecuredJWT), tokens using `alg=none` will only be accepted if the constant `jwt.UnsafeAllowNoneSignatureType` is provided as the key.
## Project Status & Versioning
This library is considered production ready. Feedback and feature requests are appreciated. The API should be considered stable. There should be very few backwards-incompatible changes outside of major version updates (and only with good reason).
This project uses [Semantic Versioning 2.0.0](http://semver.org). Accepted pull requests will land on `master`. Periodically, versions will be tagged from `master`. You can find all the releases on [the project releases page](https://github.com/dgrijalva/jwt-go/releases).
While we try to make it obvious when we make breaking changes, there isn't a great mechanism for pushing announcements out to users. You may want to use this alternative package include: `gopkg.in/dgrijalva/jwt-go.v3`. It will do the right thing WRT semantic versioning.
**BREAKING CHANGES:***
* Version 3.0.0 includes _a lot_ of changes from the 2.x line, including a few that break the API. We've tried to break as few things as possible, so there should just be a few type signature changes. A full list of breaking changes is available in `VERSION_HISTORY.md`. See `MIGRATION_GUIDE.md` for more information on updating your code.
## Usage Tips
### Signing vs Encryption
A token is simply a JSON object that is signed by its author. this tells you exactly two things about the data:
* The author of the token was in the possession of the signing secret
* The data has not been modified since it was signed
It's important to know that JWT does not provide encryption, which means anyone who has access to the token can read its contents. If you need to protect (encrypt) the data, there is a companion spec, `JWE`, that provides this functionality. JWE is currently outside the scope of this library.
### Choosing a Signing Method
There are several signing methods available, and you should probably take the time to learn about the various options before choosing one. The principal design decision is most likely going to be symmetric vs asymmetric.
Symmetric signing methods, such as HSA, use only a single secret. This is probably the simplest signing method to use since any `[]byte` can be used as a valid secret. They are also slightly computationally faster to use, though this rarely is enough to matter. Symmetric signing methods work the best when both producers and consumers of tokens are trusted, or even the same system. Since the same secret is used to both sign and validate tokens, you can't easily distribute the key for validation.
Asymmetric signing methods, such as RSA, use different keys for signing and verifying tokens. This makes it possible to produce tokens with a private key, and allow any consumer to access the public key for verification.
### Signing Methods and Key Types
Each signing method expects a different object type for its signing keys. See the package documentation for details. Here are the most common ones:
* The [HMAC signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodHMAC) (`HS256`,`HS384`,`HS512`) expect `[]byte` values for signing and validation
* The [RSA signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodRSA) (`RS256`,`RS384`,`RS512`) expect `*rsa.PrivateKey` for signing and `*rsa.PublicKey` for validation
* The [ECDSA signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodECDSA) (`ES256`,`ES384`,`ES512`) expect `*ecdsa.PrivateKey` for signing and `*ecdsa.PublicKey` for validation
### JWT and OAuth
It's worth mentioning that OAuth and JWT are not the same thing. A JWT token is simply a signed JSON object. It can be used anywhere such a thing is useful. There is some confusion, though, as JWT is the most common type of bearer token used in OAuth2 authentication.
Without going too far down the rabbit hole, here's a description of the interaction of these technologies:
* OAuth is a protocol for allowing an identity provider to be separate from the service a user is logging in to. For example, whenever you use Facebook to log into a different service (Yelp, Spotify, etc), you are using OAuth.
* OAuth defines several options for passing around authentication data. One popular method is called a "bearer token". A bearer token is simply a string that _should_ only be held by an authenticated user. Thus, simply presenting this token proves your identity. You can probably derive from here why a JWT might make a good bearer token.
* Because bearer tokens are used for authentication, it's important they're kept secret. This is why transactions that use bearer tokens typically happen over SSL.
## More
Documentation can be found [on godoc.org](http://godoc.org/github.com/dgrijalva/jwt-go).
The command line utility included in this project (cmd/jwt) provides a straightforward example of token creation and parsing as well as a useful tool for debugging your own integration. You'll also find several implementation examples in the documentation.

## `jwt-go` Version History
#### 3.2.0
* Added method `ParseUnverified` to allow users to split up the tasks of parsing and validation
* HMAC signing method returns `ErrInvalidKeyType` instead of `ErrInvalidKey` where appropriate
* Added options to `request.ParseFromRequest`, which allows for an arbitrary list of modifiers to parsing behavior. Initial set include `WithClaims` and `WithParser`. Existing usage of this function will continue to work as before.
* Deprecated `ParseFromRequestWithClaims` to simplify API in the future.
#### 3.1.0
* Improvements to `jwt` command line tool
* Added `SkipClaimsValidation` option to `Parser`
* Documentation updates
#### 3.0.0
* **Compatibility Breaking Changes**: See MIGRATION_GUIDE.md for tips on updating your code
* Dropped support for `[]byte` keys when using RSA signing methods. This convenience feature could contribute to security vulnerabilities involving mismatched key types with signing methods.
* `ParseFromRequest` has been moved to `request` subpackage and usage has changed
* The `Claims` property on `Token` is now type `Claims` instead of `map[string]interface{}`. The default value is type `MapClaims`, which is an alias to `map[string]interface{}`. This makes it possible to use a custom type when decoding claims.
* Other Additions and Changes
* Added `Claims` interface type to allow users to decode the claims into a custom type
* Added `ParseWithClaims`, which takes a third argument of type `Claims`. Use this function instead of `Parse` if you have a custom type you'd like to decode into.
* Dramatically improved the functionality and flexibility of `ParseFromRequest`, which is now in the `request` subpackage
* Added `ParseFromRequestWithClaims` which is the `FromRequest` equivalent of `ParseWithClaims`
* Added new interface type `Extractor`, which is used for extracting JWT strings from http requests. Used with `ParseFromRequest` and `ParseFromRequestWithClaims`.
* Added several new, more specific, validation errors to error type bitmask
* Moved examples from README to executable example files
* Signing method registry is now thread safe
* Added new property to `ValidationError`, which contains the raw error returned by calls made by parse/verify (such as those returned by keyfunc or json parser)
#### 2.7.0
This will likely be the last backwards compatible release before 3.0.0, excluding essential bug fixes.
* Added new option `-show` to the `jwt` command that will just output the decoded token without verifying
* Error text for expired tokens includes how long it's been expired
* Fixed incorrect error returned from `ParseRSAPublicKeyFromPEM`
* Documentation updates
#### 2.6.0
* Exposed inner error within ValidationError
* Fixed validation errors when using UseJSONNumber flag
* Added several unit tests
#### 2.5.0
* Added support for signing method none. You shouldn't use this. The API tries to make this clear.
* Updated/fixed some documentation
* Added more helpful error message when trying to parse tokens that begin with `BEARER `
#### 2.4.0
* Added new type, Parser, to allow for configuration of various parsing parameters
* You can now specify a list of valid signing methods. Anything outside this set will be rejected.
* You can now opt to use the `json.Number` type instead of `float64` when parsing token JSON
* Added support for [Travis CI](https://travis-ci.org/dgrijalva/jwt-go)
* Fixed some bugs with ECDSA parsing
#### 2.3.0
* Added support for ECDSA signing methods
* Added support for RSA PSS signing methods (requires go v1.4)
#### 2.2.0
* Gracefully handle a `nil` `Keyfunc` being passed to `Parse`. Result will now be the parsed token and an error, instead of a panic.
#### 2.1.0
Backwards compatible API change that was missed in 2.0.0.
* The `SignedString` method on `Token` now takes `interface{}` instead of `[]byte`
#### 2.0.0
There were two major reasons for breaking backwards compatibility with this update. The first was a refactor required to expand the width of the RSA and HMAC-SHA signing implementations. There will likely be no required code changes to support this change.
The second update, while unfortunately requiring a small change in integration, is required to open up this library to other signing methods. Not all keys used for all signing methods have a single standard on-disk representation. Requiring `[]byte` as the type for all keys proved too limiting. Additionally, this implementation allows for pre-parsed tokens to be reused, which might matter in an application that parses a high volume of tokens with a small set of keys. Backwards compatibilty has been maintained for passing `[]byte` to the RSA signing methods, but they will also accept `*rsa.PublicKey` and `*rsa.PrivateKey`.
It is likely the only integration change required here will be to change `func(t *jwt.Token) ([]byte, error)` to `func(t *jwt.Token) (interface{}, error)` when calling `Parse`.
* **Compatibility Breaking Changes**
* `SigningMethodHS256` is now `*SigningMethodHMAC` instead of `type struct`
* `SigningMethodRS256` is now `*SigningMethodRSA` instead of `type struct`
* `KeyFunc` now returns `interface{}` instead of `[]byte`
* `SigningMethod.Sign` now takes `interface{}` instead of `[]byte` for the key
* `SigningMethod.Verify` now takes `interface{}` instead of `[]byte` for the key
* Renamed type `SigningMethodHS256` to `SigningMethodHMAC`. Specific sizes are now just instances of this type.
* Added public package global `SigningMethodHS256`
* Added public package global `SigningMethodHS384`
* Added public package global `SigningMethodHS512`
* Renamed type `SigningMethodRS256` to `SigningMethodRSA`. Specific sizes are now just instances of this type.
* Added public package global `SigningMethodRS256`
* Added public package global `SigningMethodRS384`
* Added public package global `SigningMethodRS512`
* Moved sample private key for HMAC tests from an inline value to a file on disk. Value is unchanged.
* Refactored the RSA implementation to be easier to read
* Exposed helper methods `ParseRSAPrivateKeyFromPEM` and `ParseRSAPublicKeyFromPEM`
#### 1.0.2
* Fixed bug in parsing public keys from certificates
* Added more tests around the parsing of keys for RS256
* Code refactoring in RS256 implementation. No functional changes
#### 1.0.1
* Fixed panic if RS256 signing method was passed an invalid key
#### 1.0.0
* First versioned release
* API stabilized
* Supports creating, signing, parsing, and validating JWT tokens
* Supports RS256 and HS256 signing methods

New Features:
- Enable microsecond resolution on TIME, DATETIME and TIMESTAMP (#249)
- Support for returning table alias on Columns() (#289, #359, #382)

## Version 1.2 (2014-06-03)
Changes:
- We switched back to a "rolling release". `go get` installs the current master branch again
- Version v1 of the driver will not be maintained anymore. Go 1.0 is no longer supported by this driver
- Exported errors to allow easy checking from application code
- Enabled TCP Keepalives on TCP connections
- Optimized INFILE handling (better buffer size calculation, lazy init, ...)
- The DSN parser also checks for a missing separating slash
- Faster binary date / datetime to string formatting
- Also exported the MySQLWarning type
- mysqlConn.Close returns the first error encountered instead of ignoring all errors
- writePacket() automatically writes the packet size to the header
- readPacket() uses an iterative approach instead of the recursive approach to merge splitted packets
New Features:
- `RegisterDial` allows the usage of a custom dial function to establish the network connection
- Setting the connection collation is possible with the `collation` DSN parameter. This parameter should be preferred over the `charset` parameter
- Logging of critical errors is configurable with `SetLogger`
- Google CloudSQL support
Bugfixes:
- Allow more than 32 parameters in prepared statements
- Various old_password fixes
- Fixed TestConcurrent test to pass Go's race detection
- Fixed appendLengthEncodedInteger for large numbers
- Renamed readLengthEnodedString to readLengthEncodedString and skipLengthEnodedString to skipLengthEncodedString (fixed typo)
## Version 1.1 (2013-11-02)
Changes:
- Go-MySQL-Driver now requires Go 1.1
- Connections now use the collation `utf8_general_ci` by default. Adding `&charset=UTF8` to the DSN should not be necessary anymore
- Made closing rows and connections error tolerant. This allows for example deferring rows.Close() without checking for errors
- `[]byte(nil)` is now treated as a NULL value. Before, it was treated like an empty string / `[]byte("")`
- DSN parameter values must now be url.QueryEscape'ed. This allows text values to contain special characters, such as '&'.
- Use the IO buffer also for writing. This results in zero allocations (by the driver) for most queries
- Optimized the buffer for reading
- stmt.Query now caches column metadata
- New Logo
- Changed the copyright header to include all contributors
- Improved the LOAD INFILE documentation
- The driver struct is now exported to make the driver directly accessible
- Refactored the driver tests
- Added more benchmarks and moved all to a separate file
- Other small refactoring
New Features:
- Added *old_passwords* support: Required in some cases, but must be enabled by adding `allowOldPasswords=true` to the DSN since it is insecure
- Added a `clientFoundRows` parameter: Return the number of matching rows instead of the number of rows changed on UPDATEs
- Added TLS/SSL support: Use a TLS/SSL encrypted connection to the server. Custom TLS configs can be registered and used
Bugfixes:
- Fixed MySQL 4.1 support: MySQL 4.1 sends packets with lengths which differ from the specification
- Convert to DB timezone when inserting `time.Time`
- Splitted packets (more than 16MB) are now merged correctly
- Fixed false positive `io.EOF` errors when the data was fully read
- Avoid panics on reuse of closed connections
- Fixed empty string producing false nil values
- Fixed sign byte for positive TIME fields

2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
in Section 2.1.
3. Responsibilities
-------------------
3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients' rights in the Source Code
Form.
3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
(a) such Covered Software must also be made available in Source Code
Form, as described in Section 3.1, and You must inform recipients of
the Executable Form how they can obtain a copy of such Source Code
Form by reasonable means in a timely manner, at a charge no more
than the cost of distribution to the recipient; and
(b) You may distribute such Executable Form under the terms of this
License, or sublicense it under different terms, provided that the
license for the Executable Form does not attempt to limit or alter
the recipients' rights in the Source Code Form under this License.
3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).
3.4. Notices
You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty,
or limitations of liability) contained within the Source Code Form of
the Covered Software, except that You may alter any license notices to
the extent required to remedy known factual inaccuracies.
3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.
4. Inability to Comply Due to Statute or Regulation
---------------------------------------------------
If it is impossible for You to comply with any of the terms of this
License with respect to some or all of the Covered Software due to
statute, judicial order, or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and (b)
describe the limitations and the code they affect. Such description must
be placed in a text file included with all distributions of the Covered
Software under this License. Except to the extent prohibited by statute
or regulation, such description must be sufficiently detailed for a
recipient of ordinary skill to be able to understand it.
5. Termination
--------------
5.1. The rights granted under this License will terminate automatically
if You fail to comply with any of its terms. However, if You become
compliant, then the rights granted under this License from a particular
Contributor are reinstated (a) provisionally, unless and until such
Contributor explicitly and finally terminates Your grants, and (b) on an
ongoing basis, if such Contributor fails to notify You of the
non-compliance by some reasonable means prior to 60 days after You have
come back into compliance. Moreover, Your grants from a particular
Contributor are reinstated on an ongoing basis if such Contributor
notifies You of the non-compliance by some reasonable means, this is the
first time You have received notice of non-compliance with this License
from such Contributor, and You become compliant prior to 30 days after
Your receipt of the notice.
5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to
You by any and all Contributors for the Covered Software under Section
2.1 of this License shall terminate.
5.3. In the event of termination under Sections 5.1 or 5.2 above, all
end user license agreements (excluding distributors and resellers) which
have been validly granted by You or Your distributors under this License
prior to termination shall survive termination.
************************************************************************
* *
* 6. Disclaimer of Warranty *
* ------------------------- *
* *
* Covered Software is provided under this License on an "as is" *
* basis, without warranty of any kind, either expressed, implied, or *
* statutory, including, without limitation, warranties that the *
* Covered Software is free of defects, merchantable, fit for a *
* particular purpose or non-infringing. The entire risk as to the *
* quality and performance of the Covered Software is with You. *
* Should any Covered Software prove defective in any respect, You *
* (not any Contributor) assume the cost of any necessary servicing, *
* repair, or correction. This disclaimer of warranty constitutes an *
* essential part of this License. No use of any Covered Software is *
* authorized under this License except under this disclaimer. *
* *
************************************************************************
************************************************************************
* *
* 7. Limitation of Liability *
* -------------------------- *
* *
* Under no circumstances and under no legal theory, whether tort *
* (including negligence), contract, or otherwise, shall any *
* Contributor, or anyone who distributes Covered Software as *
* permitted above, be liable to You for any direct, indirect, *
* special, incidental, or consequential damages of any character *
* including, without limitation, damages for lost profits, loss of *
* goodwill, work stoppage, computer failure or malfunction, or any *
* and all other commercial damages or losses, even if such party *
* shall have been informed of the possibility of such damages. This *
* limitation of liability shall not apply to liability for death or *
* personal injury resulting from such party's negligence to the *
* extent applicable law prohibits such limitation. Some *
* jurisdictions do not allow the exclusion or limitation of *
* incidental or consequential damages, so this exclusion and *
* limitation may not apply to You. *
* *
************************************************************************
8. Litigation
-------------
Any litigation relating to this License may be brought only in the
courts of a jurisdiction where the defendant maintains its principal
place of business and such litigation shall be governed by laws of that
jurisdiction, without reference to its conflict-of-law provisions.
Nothing in this Section shall prevent a party's ability to bring
cross-claims or counter-claims.
9. Miscellaneous
----------------
This License represents the complete agreement concerning the subject
matter hereof. If any provision of this License is held to be
unenforceable, such provision shall be reformed only to the extent
necessary to make it enforceable. Any law or regulation which provides
that the language of a contract shall be construed against the drafter
shall not be used to construe this License against a Contributor.
10. Versions of the License
---------------------------
10.1. New Versions
Mozilla Foundation is the license steward. Except as provided in Section
10.3, no one other than the license steward has the right to modify or
publish new versions of this License. Each version will be given a
distinguishing version number.
10.2. Effect of New Versions
You may distribute the Covered Software under the terms of the version
of the License under which You originally received the Covered Software,
or under the terms of any subsequent version published by the license
steward.
10.3. Modified Versions
If you create software not governed by this License, and you want to
create a new license for such software, you may create and use a
modified version of this License if you rename the license and remove
any references to the name of the license steward (except to note that
such modified license differs from this License).
10.4. Distributing Source Code Form that is Incompatible With Secondary
Licenses
If You choose to distribute Source Code Form that is Incompatible With
Secondary Licenses under the terms of this version of the License, the

---------------------------------------
## Installation
Simple install the package to your [$GOPATH](http://code.google.com/p/go-wiki/wiki/GOPATH "GOPATH") with the [go tool](http://golang.org/cmd/go/ "go command") from shell:
```bash
$ go get github.com/go-sql-driver/mysql
```
Make sure [Git is installed](http://git-scm.com/downloads) on your machine and in your system's `PATH`.
## Usage
_Go MySQL Driver_ is an implementation of Go's `database/sql/driver` interface. You only need to import the driver and can use the full [`database/sql`](http://golang.org/pkg/database/sql) API then.
Use `mysql` as `driverName` and a valid [DSN](#dsn-data-source-name) as `dataSourceName`:
```go
import "database/sql"
import _ "github.com/go-sql-driver/mysql"
db, err := sql.Open("mysql", "user:password@/dbname")
```
[Examples are available in our Wiki](https://github.com/go-sql-driver/mysql/wiki/Examples "Go-MySQL-Driver Examples").
### DSN (Data Source Name)
The Data Source Name has a common format, like e.g. [PEAR DB](http://pear.php.net/manual/en/package.database.db.intro-dsn.php) uses it, but without type-prefix (optional parts marked by squared brackets):
```
[username[:password]@][protocol[(address)]]/dbname[?param1=value1&...&paramN=valueN]
```
A DSN in its fullest form:
```
username:password@protocol(address)/dbname?param=value
```
Except for the databasename, all values are optional. So the minimal DSN is:
```
/dbname
```
If you do not want to preselect a database, leave `dbname` empty:
```
/
```
This has the same effect as an empty DSN string:
```
```
Alternatively, [Config.FormatDSN](https://godoc.org/github.com/go-sql-driver/mysql#Config.FormatDSN) can be used to create a DSN string by filling a struct.
#### Password
Passwords can consist of any character. Escaping is **not** necessary.
#### Protocol
See [net.Dial](http://golang.org/pkg/net/#Dial) for more information which networks are available.
In general you should use an Unix domain socket if available and TCP otherwise for best performance.
#### Address
For TCP and UDP networks, addresses have the form `host:port`.
If `host` is a literal IPv6 address, it must be enclosed in square brackets.
The functions [net.JoinHostPort](http://golang.org/pkg/net/#JoinHostPort) and [net.SplitHostPort](http://golang.org/pkg/net/#SplitHostPort) manipulate addresses in this form.
For Unix domain sockets the address is the absolute path to the MySQL-Server-socket, e.g. `/var/run/mysqld/mysqld.sock` or `/tmp/mysql.sock`.
#### Parameters
*Parameters are case-sensitive!*
Notice that any of `true`, `TRUE`, `True` or `1` is accepted to stand for a true boolean value. Not surprisingly, false can be specified as any of: `false`, `FALSE`, `False` or `0`.
##### `allowAllFiles`
```
Type: bool
Valid Values: true, false
Default: false
```
`allowAllFiles=true` disables the file Whitelist for `LOAD DATA LOCAL INFILE` and allows *all* files.
[*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)
##### `allowCleartextPasswords`
```
Type: bool
Valid Values: true, false
Default: false
```
`allowCleartextPasswords=true` allows using the [cleartext client side plugin](http://dev.mysql.com/doc/en/cleartext-authentication-plugin.html) if required by an account, such as one defined with the [PAM authentication plugin](http://dev.mysql.com/doc/en/pam-authentication-plugin.html). Sending passwords in clear text may be a security problem in some configurations. To avoid problems if there is any possibility that the password would be intercepted, clients should connect to MySQL Server using a method that protects the password. Possibilities include [TLS / SSL](#tls), IPsec, or a private network.
##### `allowNativePasswords`
```
Type: bool
Valid Values: true, false
Default: false
```
`allowNativePasswords=true` allows the usage of the mysql native password method.
##### `allowOldPasswords`
```
Type: bool
Valid Values: true, false
Default: false
```
`allowOldPasswords=true` allows the usage of the insecure old password method. This should be avoided, but is necessary in some cases. See also [the old_passwords wiki page](https://github.com/go-sql-driver/mysql/wiki/old_passwords).
##### `charset`
```
Type: string
Valid Values: <name>
Default: none
```
Sets the charset used for client-server interaction (`"SET NAMES <value>"`). If multiple charsets are set (separated by a comma), the following charset is used if setting the charset failes. This enables for example support for `utf8mb4` ([introduced in MySQL 5.5.3](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)) with fallback to `utf8` for older servers (`charset=utf8mb4,utf8`).
Usage of the `charset` parameter is discouraged because it issues additional queries to the server.
Unless you need the fallback behavior, please use `collation` instead.
##### `collation`
```
Type: string
Valid Values: <name>
Default: utf8_general_ci
```
Sets the collation used for client-server interaction on connection. In contrast to `charset`, `collation` does not issue additional queries. If the specified collation is unavailable on the target server, the connection will fail.
A list of valid charsets for a server is retrievable with `SHOW COLLATION`.
##### `clientFoundRows`
```
Type: bool
Valid Values: true, false
Default: false
```
`clientFoundRows=true` causes an UPDATE to return the number of matching rows instead of the number of rows changed.
##### `columnsWithAlias`
```
Type: bool
Valid Values: true, false
Default: false
```
When `columnsWithAlias` is true, calls to `sql.Rows.Columns()` will return the table alias and the column name separated by a dot. For example:
```
SELECT u.id FROM users as u
```
will return `u.id` instead of just `id` if `columnsWithAlias=true`.
##### `interpolateParams`
```
Type: bool
Valid Values: true, false
Default: false
```
If `interpolateParams` is true, placeholders (`?`) in calls to `db.Query()` and `db.Exec()` are interpolated into a single query string with given parameters. This reduces the number of roundtrips, since the driver has to prepare a statement, execute it with given parameters and close the statement again with `interpolateParams=false`.
*This can not be used together with the multibyte encodings BIG5, CP932, GB2312, GBK or SJIS. These are blacklisted as they may [introduce a SQL injection vulnerability](http://stackoverflow.com/a/12118602/3430118)!*
##### `loc`
```
Type: string
Valid Values: <escaped name>
Default: UTC
```
Sets the location for time.Time values (when using `parseTime=true`). *"Local"* sets the system's location. See [time.LoadLocation](http://golang.org/pkg/time/#LoadLocation) for details.
Note that this sets the location for time.Time values but does not change MySQL's [time_zone setting](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html). For that see the [time_zone system variable](#system-variables), which can also be set as a DSN parameter.
Please keep in mind, that param values must be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed. Alternatively you can manually replace the `/` with `%2F`. For example `US/Pacific` would be `loc=US%2FPacific`.
##### `maxAllowedPacket`
```
Type: decimal number
Default: 0
```
Max packet size allowed in bytes. Use `maxAllowedPacket=0` to automatically fetch the `max_allowed_packet` variable from server.
##### `multiStatements`
```
Type: bool
Valid Values: true, false
Default: false
```
Allow multiple statements in one query. While this allows batch queries, it also greatly increases the risk of SQL injections. Only the result of the first query is returned, all other results are silently discarded.
When `multiStatements` is used, `?` parameters must only be used in the first statement.
##### `parseTime`
```
Type: bool
Valid Values: true, false
Default: false
```
`parseTime=true` changes the output type of `DATE` and `DATETIME` values to `time.Time` instead of `[]byte` / `string`
##### `readTimeout`
```
Type: decimal number
Default: 0
```
I/O read timeout. The value must be a decimal number with an unit suffix ( *"ms"*, *"s"*, *"m"*, *"h"* ), such as *"30s"*, *"0.5m"* or *"1m30s"*.
##### `strict`
```
Type: bool
Valid Values: true, false
Default: false
```
`strict=true` enables a driver-side strict mode in which MySQL warnings are treated as errors. This mode should not be used in production as it may lead to data corruption in certain situations.
A server-side strict mode, which is safe for production use, can be set via the [`sql_mode`](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html) system variable.
By default MySQL also treats notes as warnings. Use [`sql_notes=false`](http://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_sql_notes) to ignore notes.
##### `timeout`
```
Type: decimal number
Default: OS default
```
*Driver* side connection timeout. The value must be a decimal number with an unit suffix ( *"ms"*, *"s"*, *"m"*, *"h"* ), such as *"30s"*, *"0.5m"* or *"1m30s"*. To set a server side timeout, use the parameter [`wait_timeout`](http://dev.mysql.com/doc/refman/5.6/en/server-system-variables.html#sysvar_wait_timeout).
##### `tls`
```
Type: bool / string
Valid Values: true, false, skip-verify, <name>
Default: false
```
`tls=true` enables TLS / SSL encrypted connection to the server. Use `skip-verify` if you want to use a self-signed or invalid certificate (server side). Use a custom value registered with [`mysql.RegisterTLSConfig`](http://godoc.org/github.com/go-sql-driver/mysql#RegisterTLSConfig).
##### `writeTimeout`
```
Type: decimal number
Default: 0
```
I/O write timeout. The value must be a decimal number with an unit suffix ( *"ms"*, *"s"*, *"m"*, *"h"* ), such as *"30s"*, *"0.5m"* or *"1m30s"*.
##### System Variables
Any other parameters are interpreted as system variables:
* `<boolean_var>=<value>`: `SET <boolean_var>=<value>`
* `<enum_var>=<value>`: `SET <enum_var>=<value>`
* `<string_var>=%27<value>%27`: `SET <string_var>='<value>'`
Rules:
* The values for string variables must be quoted with '
* The values must also be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed!
(which implies values of string variables must be wrapped with `%27`)
Examples:
* `autocommit=1`: `SET autocommit=1`
* [`time_zone=%27Europe%2FParis%27`](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html): `SET time_zone='Europe/Paris'`
* [`tx_isolation=%27REPEATABLE-READ%27`](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_tx_isolation): `SET tx_isolation='REPEATABLE-READ'`
#### Examples
```
user@unix(/path/to/socket)/dbname
```
```
root:pw@unix(/tmp/mysql.sock)/myDatabase?loc=Local
```
```
user:password@tcp(localhost:5555)/dbname?tls=skip-verify&autocommit=true
```
Treat warnings as errors by setting the system variable [`sql_mode`](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html):
```
user:password@/dbname?sql_mode=TRADITIONAL
```
TCP via IPv6:
```
user:password@tcp([de:ad:be:ef::ca:fe]:80)/dbname?timeout=90s&collation=utf8mb4_unicode_ci
```
TCP on a remote host, e.g. Amazon RDS:
```
id:password@tcp(your-amazonaws-uri.com:3306)/dbname
```
Google Cloud SQL on App Engine (First Generation MySQL Server):
```
user@cloudsql(project-id:instance-name)/dbname
```
Google Cloud SQL on App Engine (Second Generation MySQL Server):
```
user@cloudsql(project-id:regionname:instance-name)/dbname
```
TCP using default port (3306) on localhost:
```
user:password@tcp/dbname?charset=utf8mb4,utf8&sys_var=esc%40ped
```
Use the default protocol (tcp) and host (localhost:3306):
```
user:password@/dbname
```
No Database preselected:
```
user:password@/
```
### `LOAD DATA LOCAL INFILE` support
For this feature you need direct access to the package. Therefore you must change the import path (no `_`):
```go
import "github.com/go-sql-driver/mysql"
```
Files must be whitelisted by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the Whitelist check must be deactivated by using the DSN parameter `allowAllFiles=true` ([*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)).
To use a `io.Reader` a handler function must be registered with `mysql.RegisterReaderHandler(name, handler)` which returns a `io.Reader` or `io.ReadCloser`. The Reader is available with the filepath `Reader::<name>` then. Choose different names for different handlers and `DeregisterReaderHandler` when you don't need it anymore.
See the [godoc of Go-MySQL-Driver](http://godoc.org/github.com/go-sql-driver/mysql "golang mysql driver documentation") for details.
### `time.Time` support
The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your programm.
However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical opposite in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](http://golang.org/pkg/time/#Location) with the `loc` DSN parameter.
**Caution:** As of Go 1.1, this makes `time.Time` the only variable type you can scan `DATE` and `DATETIME` values into. This breaks for example [`sql.RawBytes` support](https://github.com/go-sql-driver/mysql/wiki/Examples#rawbytes).
Alternatively you can use the [`NullTime`](http://godoc.org/github.com/go-sql-driver/mysql#NullTime) type as the scan destination, which works with both `time.Time` and `string` / `[]byte`.
### Unicode support
Since version 1.1 Go-MySQL-Driver automatically uses the collation `utf8_general_ci` by default.
Other collations / charsets can be set using the [`collation`](#collation) DSN parameter.
Version 1.0 of the driver recommended adding `&charset=utf8` (alias for `SET NAMES utf8`) to the DSN to enable proper UTF-8 support. This is not necessary anymore. The [`collation`](#collation) parameter should be preferred to set another collation / charset than the default.
See http://dev.mysql.com/doc/refman/5.7/en/charset-unicode.html for more details on MySQL's Unicode support.
## Testing / Development
To run the driver tests you may need to adjust the configuration. See the [Testing Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details.
Go-MySQL-Driver is not feature-complete yet. Your help is very appreciated.
If you want to contribute, you can work on an [open issue](https://github.com/go-sql-driver/mysql/issues?state=open) or review a [pull request](https://github.com/go-sql-driver/mysql/pulls).

# sqlx
[![Build Status](https://travis-ci.org/jmoiron/sqlx.svg?branch=master)](https://travis-ci.org/jmoiron/sqlx) [![Coverage Status](https://coveralls.io/repos/github/jmoiron/sqlx/badge.svg?branch=master)](https://coveralls.io/github/jmoiron/sqlx?branch=master) [![Godoc](http://img.shields.io/badge/godoc-reference-blue.svg?style=flat)](https://godoc.org/github.com/jmoiron/sqlx) [![license](http://img.shields.io/badge/license-MIT-red.svg?style=flat)](https://raw.githubusercontent.com/jmoiron/sqlx/master/LICENSE)
sqlx is a library which provides a set of extensions on go's standard
`database/sql` library. The sqlx versions of `sql.DB`, `sql.TX`, `sql.Stmt`,
et al. all leave the underlying interfaces untouched, so that their interfaces
are a superset on the standard ones. This makes it relatively painless to
integrate existing codebases using database/sql with sqlx.
Major additional concepts are:
* Marshal rows into structs (with embedded struct support), maps, and slices
* Named parameter support including prepared statements
* `Get` and `Select` to go quickly from query to struct/slice
In addition to the [godoc API documentation](http://godoc.org/github.com/jmoiron/sqlx),
there is also some [standard documentation](http://jmoiron.github.io/sqlx/) that
explains how to use `database/sql` along with sqlx.
## Recent Changes
* sqlx/types.JsonText has been renamed to JSONText to follow Go naming conventions.
This breaks backwards compatibility, but it's in a way that is trivially fixable
(`s/JsonText/JSONText/g`). The `types` package is both experimental and not in
active development currently.
* Using Go 1.6 and below with `types.JSONText` and `types.GzippedText` can be _potentially unsafe_, **especially** when used with common auto-scan sqlx idioms like `Select` and `Get`. See [golang bug #13905](https://github.com/golang/go/issues/13905).
### Backwards Compatibility
There is no Go1-like promise of absolute stability, but I take the issue seriously
and will maintain the library in a compatible state unless vital bugs prevent me
from doing so. Since [#59](https://github.com/jmoiron/sqlx/issues/59) and
[#60](https://github.com/jmoiron/sqlx/issues/60) necessitated breaking behavior,
a wider API cleanup was done at the time of fixing. It's possible this will happen
in future; if it does, a git tag will be provided for users requiring the old
behavior to continue to use it until such a time as they can migrate.
## install
go get github.com/jmoiron/sqlx
## issues
Row headers can be ambiguous (`SELECT 1 AS a, 2 AS a`), and the result of
`Columns()` does not fully qualify column names in queries like:
```sql
SELECT a.id, a.name, b.id, b.name FROM foos AS a JOIN foos AS b ON a.parent = b.id;
```
making a struct or map destination ambiguous. Use `AS` in your queries
to give columns distinct names, `rows.Scan` to scan them manually, or
`SliceScan` to get a slice of results.
## usage
Below is an example which shows some common use cases for sqlx. Check
[sqlx_test.go](https://github.com/jmoiron/sqlx/blob/master/sqlx_test.go) for more
usage.

# reflectx
The sqlx package has special reflect needs. In particular, it needs to:
* be able to map a name to a field
* understand embedded structs
* understand mapping names to fields by a particular tag
* user specified name -> field mapping functions
These behaviors mimic the behaviors by the standard library marshallers and also the
behavior of standard Go accessors.
The first two are amply taken care of by `Reflect.Value.FieldByName`, and the third is
addressed by `Reflect.Value.FieldByNameFunc`, but these don't quite understand struct
tags in the ways that are vital to most marshallers, and they are slow.
This reflectx package extends reflect to achieve these goals.
