func CallbackHandler ¶

func CallbackHandler(config *oauth2.Config, success, failure http.Handler) http.Handler

CallbackHandler handles Google redirection URI requests and adds the Google access token and Userinfoplus to the ctx. If authentication succeeds, handling delegates to the success handler, otherwise to the failure handler.

func LoginHandler ¶

func LoginHandler(config *oauth2.Config, failure http.Handler) http.Handler

LoginHandler handles Google login requests by reading the state value from the ctx and redirecting requests to the AuthURL with that state value.

func StateHandler ¶

func StateHandler(config gologin.CookieConfig, success http.Handler) http.Handler

StateHandler checks for a state cookie. If found, the state value is read and added to the ctx. Otherwise, a non-guessable value is added to the ctx and to a (short-lived) state cookie issued to the requester.

Implements OAuth 2 RFC 6749 10.12 CSRF Protection. If you wish to issue state params differently, write a http.Handler which sets the ctx state, using oauth2 WithState(ctx, state) since it is required by LoginHandler and CallbackHandler.

func UserFromContext ¶

func UserFromContext(ctx context.Context) (*google.Userinfoplus, error)

UserFromContext returns the Google Userinfoplus from the ctx.

func WithUser ¶

func WithUser(ctx context.Context, user *google.Userinfoplus) context.Context

WithUser returns a copy of ctx that stores the Google Userinfoplus.
