Chaining allows advanced customization, if desired. Once authentication succeeds, your `success` handler will have access to the user's access token and associated User/Account.\n\n## Usage\n\nChoose a subpackage such as `github` or `twitter`. `LoginHandler` and `Callback` `http.Handler`'s chain together lower level `oauth1` or `oauth2` handlers to authenticate users and fetch the Github or Twitter `User`, before calling your `success` `http.Handler`.\n\nLet's walk through Github and Twitter web login examples.\n\n### Github OAuth2\n\nRegister the `LoginHandler` and `CallbackHandler` on your `http.ServeMux`.\n\n```go\nconfig := \u0026oauth2.Config{\n    ClientID:     \"GithubClientID\",\n    ClientSecret: \"GithubClientSecret\",\n    RedirectURL:  \"http://localhost:8080/callback\",\n    Endpoint:     githubOAuth2.Endpoint,\n}\nmux := http.NewServeMux()\nstateConfig := gologin.DebugOnlyCookieConfig\nmux.Handle(\"/login\", github.CSRFHandler(stateConfig, github.LoginHandler(config, nil)))\nmux.Handle(\"/callback\", github.CSRFHandler(stateConfig, github.CallbackHandler(config, issueSession(), nil)))\n```\n\nThe `CSRFHandler` checks for an OAuth2 state parameter cookie, generates a non-guessable state as a short-lived cookie if missing, and passes the state value in the ctx. The `CookieConfig` allows the cookie name or expiration (default 60 seconds) to be configured. In production, use a config like `gologin.DefaultCookieConfig` which sets *Secure* true to require cookies be sent over HTTPS. If you wish to persist state parameters a different way, you may chain your own `http.Handler`. ([info](#state-parameters))\n\nThe `github` `LoginHandler` reads the state from the ctx and redirects to the AuthURL (at github.com) to prompt the user to grant access. Passing nil for the `failure` handler just means the `DefaultFailureHandler` should be used, which reports errors. ([info](#failure-handlers))\n\nThe `github` `CallbackHandler` receives an auth code and state OAuth2 redirection, validates the state against the state in the ctx, and exchanges the auth code for an OAuth2 Token. The `github` CallbackHandler wraps the lower level `oauth2` `CallbackHandler` to further use the Token to obtain the Github `User` before calling through to the success or failure handlers.\n\n\u003cimg src=\"https://storage.googleapis.com/dghubble/gologin-github.png\"\u003e\n\nNext, write the success `http.Handler` to do something with the Token and Github User added to the `ctx`.\n\n```go\nfunc issueSession() http.Handler {\n    fn := func(w http.ResponseWriter, req *http.Request) {\n        ctx := req.Context()\n        token, _ := oauth2Login.TokenFromContext(ctx)\n        githubUser, err := github.UserFromContext(ctx)\n        // handle errors and grant the visitor a session (cookie, token, etc.)\n    }\n    return http.HandlerFunc(fn)\n}\n```\n\nSee the [Github tutorial](examples/github) for a web app you can run from the command line.\n\n### Twitter OAuth1\n\nRegister the `LoginHandler` and `CallbackHandler` on your `http.ServeMux`.\n\n```go\nconfig := \u0026oauth1.Config{\n    ConsumerKey:    \"TwitterConsumerKey\",\n    ConsumerSecret: \"TwitterConsumerSecret\",\n    CallbackURL:    \"http://localhost:8080/callback\",\n    Endpoint:       twitterOAuth1.AuthorizeEndpoint,\n}\nmux := http.NewServeMux()\nmux.Handle(\"/login\", twitter.LoginHandler(config, nil))\nmux.Handle(\"/callback\", twitter.CallbackHandler(config, issueSession(), nil))\n```\n\nThe `twitter` `LoginHandler` obtains a request token and secret, adds them to the ctx, and redirects to the AuthorizeURL to prompt the user to grant access. Passing nil for the `failure` handler just means the `DefaultFailureHandler` should be used, which reports errors. ([info](#failure-handlers))\n\nThe `twitter` `CallbackHandler` receives an OAuth1 token and verifier, reads the request secret from the ctx, and obtains an OAuth1 access token and secret. The `twitter` CallbackHandler wraps the lower level `oauth1` CallbackHandler to further use the access token/secret to obtain the Twitter `User` before calling through to the success or failure handlers.\n\n\u003cimg src=\"https://storage.googleapis.com/dghubble/gologin-twitter.png\"\u003e\n\nNext, write the success `http.Handler` to do something with the access token/secret and Twitter User added to the `ctx`.\n\n```go\nfunc success() http.Handler {\n    fn := func(w http.ResponseWriter, req *http.Request) {\n        ctx := req.Context()\n        accessToken, accessSecret, _ := oauth1Login.AccessTokenFromContext(ctx)\n        twitterUser, err := twitter.UserFromContext(ctx)\n        // handle errors and grant the visitor a session (cookie, token, etc.)\n    }\n    return http.HandlerFunc(fn)\n}\n```\n\n*Note: Some OAuth1 providers (not Twitter), require the request secret be persisted until the callback is received. For this reason, the lower level `oauth1` package splits LoginHandler functionality into a `LoginHandler` and `AuthRedirectHandler`. Provider packages, like `tumblr`, chain these together for you, but the lower level handlers are there if needed.\n\nSee the [Twitter tutorial](examples/twitter) for a web app you can run from the command line.\n\n### State Parameters\n\nOAuth2 `CSRFHandler` implements OAuth 2 [RFC 6749](https://tools.ietf.org/html/rfc6749) 10.12 CSRF Protection using non-guessable values in short-lived HTTPS-only cookies to provide reasonable assurance the user in the login phase and callback phase are the same. If you wish to implement this differently, write a `http.Handler` which sets a *state* in the ctx, which is expected by LoginHandler and CallbackHandler.\n\nYou may use `oauth2.WithState(context.Context, state string)` for this. [docs](https://godoc.org/github.com/dghubble/gologin/oauth2#WithState)\n\n### Failure Handlers\n\nIf you wish to define your own failure `http.Handler`, you can get the error from the `ctx` using `gologin.ErrorFromContext(ctx)`.\n\n## Mobile\n\nTwitter includes a `TokenHandler` which can be useful for building APIs for mobile devices which use Login with Twitter.\n\n## Goals\n\nCreate small, chainable handlers to correctly implement the steps of common authentication flows. Handle provider-specific validation requirements.\n\n## Motivations\n\nPackage `gologin` implements authorization flow steps with chained handlers.\n\n* Authentication should be performed with chainable handlers to allow customization, swapping, or adding additional steps easily.\n* Authentication should be orthogonal to the session system. Let users choose their session/token library.\n* OAuth2 State CSRF should be included out of the box, but easy to customize.\n* Packages should import only what is required. OAuth1 and OAuth2 packages are separate.\n* `http.Handler` and `context` are powerful, flexible, and in the standard library.\n\nProjects [goth](https://github.com/markbates/goth) and [gomniauth](https://github.com/stretchr/gomniauth) aim to provide a similar login solution with a different design. Check them out if you decide you don't like the ideas in `gologin`.\n\n## Contributing\n\nNew auth providers can be implemented by composing the handlers in the `oauth1` or `oauth2` subpackages.
