OSIN CLIENT =========== Golang OAuth2 client library ---------------------------- OSINCLI is an OAuth2 client library for the Go language, as specified at http://tools.ietf.org/html/rfc6749. Using it, you can access an OAuth2 authenticated service. The library follows the RFC recommendations, but allows some differences, like passing the client secret in the url instead of using the Authorization header. ### Example import "github.com/RangelReale/osincli" config := &osincli.ClientConfig{ ClientId: "xxxxxxxxxxxx.apps.googleusercontent.com", ClientSecret: "secret", AuthorizeUrl: "https://accounts.google.com/o/oauth2/auth", TokenUrl: "https://accounts.google.com/o/oauth2/token", RedirectUrl: "http://localhost:14001/appauth", ErrorsInStatusCode: true, SendClientSecretInParams: true, Scope: "https://www.googleapis.com/auth/plus.login", } client, err := osincli.NewClient(config) if err != nil { panic(err) } // create a new request to generate the url areq := client.NewAuthorizeRequest(osincli.CODE) areq.CustomParameters["access_type"] = "online" areq.CustomParameters["approval_prompt"] = "auto" // Home http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) { u := areq.GetAuthorizeUrl() w.Write([]byte(fmt.Sprintf("<a href=\"%s\">Login</a>", u.String()))) }) // Auth endpoint http.HandleFunc("/appauth", func(w http.ResponseWriter, r *http.Request) { // parse a token request if areqdata, err := areq.HandleRequest(r); err == nil { treq := client.NewAccessRequest(osincli.AUTHORIZATION_CODE, areqdata) // exchange the authorize token for the access token ad, err := treq.GetToken() if err == nil { w.Write([]byte(fmt.Sprintf("Access token: %+v\n\n", ad))) // use the token in ad.AccessToken } else { w.Write([]byte(fmt.Sprintf("ERROR: %s\n", err))) } } else { w.Write([]byte(fmt.Sprintf("ERROR: %s\n", err))) } }) http.ListenAndServe(":14001", nil) Load your web browser at: http://localhost:14001 ### License The code is licensed using "New BSD" license. ### Author Rangel Reale
