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) - } -``` diff --git a/backend/vendor/github.com/dgrijalva/jwt-go/README.md b/backend/vendor/github.com/dgrijalva/jwt-go/README.md deleted file mode 100644 index d358d881..00000000 --- a/backend/vendor/github.com/dgrijalva/jwt-go/README.md +++ /dev/null @@ -1,100 +0,0 @@ -# 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.

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. diff --git a/backend/vendor/github.com/dgrijalva/jwt-go/VERSION_HISTORY.md b/backend/vendor/github.com/dgrijalva/jwt-go/VERSION_HISTORY.md deleted file mode 100644 index 63702983..00000000 --- a/backend/vendor/github.com/dgrijalva/jwt-go/VERSION_HISTORY.md +++ /dev/null @@ -1,118 +0,0 @@ -## `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 \ No newline at end of file diff --git a/backend/vendor/github.com/dgrijalva/jwt-go/claims.go b/backend/vendor/github.com/dgrijalva/jwt-go/claims.go deleted file mode 100644 index f0228f02..00000000 --- a/backend/vendor/github.com/dgrijalva/jwt-go/claims.go +++ /dev/null @@ -1,134 +0,0 @@ -package jwt -

-## Issues - -* Request features and report bugs using the [GitHub Issue Tracker](https://github.com/fsnotify/fsnotify/issues). -* Please indicate the platform you are using fsnotify on. -* A code example to reproduce the problem is appreciated. - -## Pull Requests - -### Contributor License Agreement - -fsnotify is derived from code in the [golang.org/x/exp](https://godoc.org/golang.org/x/exp) package and it may be included [in the standard library](https://github.com/fsnotify/fsnotify/issues/1) in the future. Therefore fsnotify carries the same [LICENSE](https://github.com/fsnotify/fsnotify/blob/master/LICENSE) as Go. Contributors retain their copyright, so you need to fill out a short form before we can accept your contribution: [Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual). - -Please indicate that you have signed the CLA in your pull request. - -### How fsnotify is Developed - -* Development is done on feature branches. -* Tests are run on BSD, Linux, macOS and Windows. -* Pull requests are reviewed and [applied to master][am] using [hub][]. - * Maintainers may modify or squash commits rather than asking contributors to. -* To issue a new release, the maintainers will: - * Update the CHANGELOG - * Tag a version, which will become available through gopkg.in. - -### How to Fork - -For smooth sailing, always use the original import path. Installing with `go get` makes this easy. - -1. Install from GitHub (`go get -u github.com/fsnotify/fsnotify`) -2. Create your feature branch (`git checkout -b my-new-feature`) -3. Ensure everything works and the tests pass (see below) -4. Commit your changes (`git commit -am 'Add some feature'`) - -Contribute upstream: - -1. Fork fsnotify on GitHub -2. Add your remote (`git remote add fork git@github.com:mycompany/repo.git`) -3. Push to the branch (`git push fork my-new-feature`) -4. Create a new Pull Request on GitHub - -This workflow is [thoroughly explained by Katrina Owen](https://splice.com/blog/contributing-open-source-git-repositories-go/). - -### Testing - -fsnotify uses build tags to compile different code on Linux, BSD, macOS, and Windows. - -Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on. - -To aid in cross-platform testing there is a Vagrantfile for Linux and BSD. - -* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/) -* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder. -* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password) -* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd fsnotify/fsnotify; go test'`. -* When you're done, you will want to halt or destroy the Vagrant boxes. - -Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory. - -Right now there is no equivalent solution for Windows and macOS, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads). - -### Maintainers - -Help maintaining fsnotify is welcome. To be a maintainer: - -* Submit a pull request and sign the CLA as above. -* You must be able to run the test suite on Mac, Windows, Linux and BSD. - -To keep master clean, the fsnotify project uses the "apply mail" workflow outlined in Nathaniel Talbott's post ["Merge pull request" Considered Harmful][am]. This requires installing [hub][]. - -All code changes should be internal pull requests. - -Releases are tagged using [Semantic Versioning](http://semver.org/). - -[hub]: https://github.com/github/hub -[am]: http://blog.spreedly.com/2014/06/24/merge-pull-request-considered-harmful/#.VGa5yZPF_Zs diff --git a/backend/vendor/github.com/fsnotify/fsnotify/LICENSE b/backend/vendor/github.com/fsnotify/fsnotify/LICENSE deleted file mode 100644 index f21e5408..00000000 --- a/backend/vendor/github.com/fsnotify/fsnotify/LICENSE +++ /dev/null @@ -1,28 +0,0 @@ -Copyright (c) 2012 The Go Authors.

A temporary workaround is to add your folder(s) to the *Spotlight Privacy settings* until we have a native FSEvents implementation (see [#11][]). - -**How many files can be watched at once?** - -There are OS-specific limits as to how many watches can be created: -* Linux: /proc/sys/fs/inotify/max_user_watches contains the limit, reaching this limit results in a "no space left on device" error. -* BSD / OSX: sysctl variables "kern.maxfiles" and "kern.maxfilesperproc", reaching these limits results in a "too many open files" error. - -[#62]: https://github.com/howeyc/fsnotify/issues/62 -[#18]: https://github.com/fsnotify/fsnotify/issues/18 -[#11]: https://github.com/fsnotify/fsnotify/issues/11 -[#7]: https://github.com/howeyc/fsnotify/issues/7 - -[contributing]: https://github.com/fsnotify/fsnotify/blob/master/CONTRIBUTING.md - -## Related Projects - -* [notify](https://github.com/rjeczalik/notify) -* [fsevents](https://github.com/fsnotify/fsevents) - diff --git a/backend/vendor/github.com/fsnotify/fsnotify/fen.go b/backend/vendor/github.com/fsnotify/fsnotify/fen.go deleted file mode 100644 index ced39cb8..00000000 --- a/backend/vendor/github.com/fsnotify/fsnotify/fen.go +++ /dev/null @@ -1,37 +0,0 @@ -// Copyright 2010 The Go Authors.

Check the full docs on tags usage [here](http://godoc.org/gopkg.in/go-playground/validator.v8#hdr-Baked_In_Validators_and_Tags). - -Note that you need to set the corresponding binding tag on all fields you want to bind. For example, when binding from JSON, set `json:"fieldname"`. - -Also, Gin provides two sets of methods for binding: -- **Type** - Must bind - - **Methods** - `Bind`, `BindJSON`, `BindXML`, `BindQuery`, `BindYAML` - - **Behavior** - These methods use `MustBindWith` under the hood. If there is a binding error, the request is aborted with `c.AbortWithError(400, err).SetType(ErrorTypeBind)`. This sets the response status code to 400 and the `Content-Type` header is set to `text/plain; charset=utf-8`. Note that if you try to set the response code after this, it will result in a warning `[GIN-debug] [WARNING] Headers were already written. Wanted to override status code 400 with 422`. If you wish to have greater control over the behavior, consider using the `ShouldBind` equivalent method. -- **Type** - Should bind - - **Methods** - `ShouldBind`, `ShouldBindJSON`, `ShouldBindXML`, `ShouldBindQuery`, `ShouldBindYAML` - - **Behavior** - These methods use `ShouldBindWith` under the hood. If there is a binding error, the error is returned and it is the developer's responsibility to handle the request and error appropriately. - -When using the Bind-method, Gin tries to infer the binder depending on the Content-Type header. If you are sure what you are binding, you can use `MustBindWith` or `ShouldBindWith`. - -You can also specify that specific fields are required. If a field is decorated with `binding:"required"` and has a empty value when binding, an error will be returned. - -```go -// Binding from JSON -type Login struct { - User string `form:"user" json:"user" xml:"user" binding:"required"` - Password string `form:"password" json:"password" xml:"password" binding:"required"` -} - -func main() { - router := gin.Default() - - // Example for binding JSON ({"user": "manu", "password": "123"}) - router.POST("/loginJSON", func(c *gin.Context) { - var json Login - if err := c.ShouldBindJSON(&json); err != nil { - c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()}) - return - } - - if json.User != "manu" || json.Password != "123" { - c.JSON(http.StatusUnauthorized, gin.H{"status": "unauthorized"}) - return - } - - c.JSON(http.StatusOK, gin.H{"status": "you are logged in"}) - }) - - // Example for binding XML ( - // - // - // user - // 123 - // ) - router.POST("/loginXML", func(c *gin.Context) { - var xml Login - if err := c.ShouldBindXML(&xml); err != nil { - c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()}) - return - } - - if xml.User != "manu" || xml.Password != "123" { - c.JSON(http.StatusUnauthorized, gin.H{"status": "unauthorized"}) - return - } - - c.JSON(http.StatusOK, gin.H{"status": "you are logged in"}) - }) - - // Example for binding a HTML form (user=manu&password=123) - router.POST("/loginForm", func(c *gin.Context) { - var form Login - // This will infer what binder to use depending on the content-type header. - if err := c.ShouldBind(&form); err != nil { - c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()}) - return - } - - if form.User != "manu" || form.Password != "123" { - c.JSON(http.StatusUnauthorized, gin.H{"status": "unauthorized"}) - return - } - - c.JSON(http.StatusOK, gin.H{"status": "you are logged in"}) - }) - - // Listen and serve on 0.0.0.0:8080 - router.Run(":8080") -} -``` - -**Sample request** -```shell -$ curl -v -X POST \ - http://localhost:8080/loginJSON \ - -H 'content-type: application/json' \ - -d '{ "user": "manu" }' -> POST /loginJSON HTTP/1.1 -> Host: localhost:8080 -> User-Agent: curl/7.51.0 -> Accept: */* -> content-type: application/json -> Content-Length: 18 -> -* upload completely sent off: 18 out of 18 bytes -< HTTP/1.1 400 Bad Request -< Content-Type: application/json; charset=utf-8 -< Date: Fri, 04 Aug 2017 03:51:31 GMT -< Content-Length: 100 -< -{"error":"Key: 'Login.Password' Error:Field validation for 'Password' failed on the 'required' tag"} -``` - -**Skip validate** - -When running the above example using the above the `curl` command, it returns error.

The object's default key string is the struct field name -// but can be specified in the struct field's tag value.

Examples: -// -// // Field is ignored by this package. -// Field int `json:"-"` -// -// // Field appears in JSON as key "myName". -// Field int `json:"myName"` -// -// // Field appears in JSON as key "myName" and -// // the field is omitted from the object if its value is empty, -// // as defined above. -// Field int `json:"myName,omitempty"` -// -// // Field appears in JSON as key "Field" (the default), but -// // the field is skipped if empty. -// // Note the leading comma. -// Field int `json:",omitempty"` -// -// The "string" option signals that a field is stored as JSON inside a -// JSON-encoded string. It applies only to fields of string, floating point, -// integer, or boolean types. This extra level of encoding is sometimes used -// when communicating with JavaScript programs: -// -// Int64String int64 `json:",string"` -// -// The key name will be used if it's a non-empty string consisting of -// only Unicode letters, digits, dollar signs, percent signs, hyphens, -// underscores and slashes. -// -// Anonymous struct fields are usually marshaled as if their inner exported fields -// were fields in the outer struct, subject to the usual Go visibility rules amended -// as described in the next paragraph. -// An anonymous struct field with a name given in its JSON tag is treated as -// having that name, rather than being anonymous. -// An anonymous struct field of interface type is treated the same as having -// that type as its name, rather than being anonymous. -// -// The Go visibility rules for struct fields are amended for JSON when -// deciding which field to marshal or unmarshal. If there are -// multiple fields at the same level, and that level is the least -// nested (and would therefore be the nesting level selected by the -// usual Go rules), the following extra rules apply: -// -// 1) Of those fields, if any are JSON-tagged, only tagged fields are considered, -// even if there are multiple untagged fields that would otherwise conflict. -// 2) If there is exactly one field (tagged or not according to the first rule), that is selected. -// 3) Otherwise there are multiple fields, and all are ignored; no error occurs. -// -// Handling of anonymous struct fields is new in Go 1.1. -// Prior to Go 1.1, anonymous struct fields were ignored.
