)
Errors which may occur on login.
Functions ¶
func CallbackHandler ¶
CallbackHandler handles OAuth2 redirection URI requests by parsing the auth code and state, comparing with the state value from the ctx, and obtaining an OAuth2 Token.
func LoginHandler ¶
LoginHandler handles OAuth2 login requests by reading the state value from the ctx and redirecting requests to the AuthURL with that state value.
func StateFromContext ¶
StateFromContext returns the state value from the ctx.
func StateHandler ¶
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 TokenFromContext ¶
TokenFromContext returns the Token from the ctx.
