The AuthHandler Interface for goauth2

AuthHandler.go

// These handlers should basically perform like a simple form submission.
// Once complete, notify the client using the redirects.

// As always, see http://tools.ietf.org/html/draft-ietf-oauth-v2-29 for reference.

// AuthHandler performs authentication with the resource owner
// It is important they follow OAuth 2.0 specification. For ease of use,
// A reference to the Store is passed in the OAuthRequest.
type AuthHandler interface {
	// Authorize a client using the Authorization Code Grant Flow
	// After authorization, the server should redirect using
	// oar.AuthCodeRedirect()
	Authorize(w http.ResponseWriter, r *http.Request, oar *OAuthRequest)
	// Authorize a client using the Implicit Grant Flow
	// After authorization, the server should redirect using
	// oar.AuthCodeRedirect()
	AuthorizeImplicit(w http.ResponseWriter, r *http.Request, oar *OAuthRequest)
}

// Use these two functions to call the redirect
// A nil error means everything is authorized
// A non-nil error will be notified in the spec-compliant way.
func (req *OAuthRequest) ImplicitRedirect(w http.ResponseWriter, r *http.Request, err error);
func (req *OAuthRequest) AuthCodeRedirect(w http.ResponseWriter, r *http.Request, err error);
