Return token

[djedjethai]

Hi, I am using oauth2 as an authorization server to secure a microservices based app, doing like so I needed the *oauth2.Token to be returned as a payload(instead of being redirected), so I added 5 lines for(in /server/server.go).

type Server struct {
	Config                       *Config
	Manager                      oauth2.Manager
	..........
	IsModeAPI                    bool
}

func (s *Server) SetModeAPI() {
	s.IsModeAPI = true
}

func (s *Server) redirect(w http.ResponseWriter, req *AuthorizeRequest, data map[string]interface{}) error {
	if !s.IsModeAPI {
		uri, err := s.GetRedirectURI(req, data)
		if err != nil {
			return err
		}

		w.Header().Set("Location", uri)
		w.WriteHeader(302)
		return nil

	} else {
		w.Header().Set("Content-Type", "application/json")
		w.Header().Set("Cache-Control", "no-store")
		w.Header().Set("Pragma", "no-cache")

		w.WriteHeader(http.StatusOK)
		return json.NewEncoder(w).Encode(data)
	}
}

It does not create any breaking change, if you like it ?
As well I have given a simple but quite complet flow about a way to use it this way, in the /example/secureYourMicroservices, if you like it ? Wish you the best.
