Functions

func AuthorizeHandler

func AuthorizeHandler(schema *proto.Schema) common.HandlerFunc

AuthorizeHandler is a redirection endpoint that will redirect to the provider's sign-in/auth page

func CallbackHandler

func CallbackHandler(schema *proto.Schema) common.HandlerFunc

CallbackHandler is called by the provider after the authentication process is complete

If there is something wrong with the syntax of the request, such as the redirect_uri or client_id is invalid, then it’s important not to redirect the user and instead you should show the error message directly. This is to avoid letting your authorization server be used as an open redirector.

func GetClientSecret

func GetClientSecret(ctx context.Context, provider *config.Provider) (string, bool)

func ProvidersHandler

func ProvidersHandler(schema *proto.Schema) common.HandlerFunc

func RevokeHandler

func RevokeHandler(schema *proto.Schema) common.HandlerFunc

func TokenEndpointHandler

func TokenEndpointHandler(schema *proto.Schema) common.HandlerFunc

TokenEndpointHandler handles requests to the token endpoint for the various grant types we support. OAuth2.0 specification: https://datatracker.ietf.org/doc/html/rfc6749#section-3.2 OpenID Connect specification for Token Endpoint: https://openid.net/specs/openid-connect-standard-1_0-21_orig.html#token_ep
