OSIN

Golang OAuth2 server library

OSIN is an OAuth2 server library for the Go language, as specified at http://tools.ietf.org/html/rfc6749.

Using it, you can build your own OAuth2 authentication service.

The library implements the majority of the specification, like authorization and token endpoints, and authorization code, implicit, resource owner and client credentials grant types.

Dependencies

• go-uuid (http://code.google.com/p/go-uuid)

Example Server

import "github.com/RangelReale/osin"

// TestStorage implements the "osin.Storage" interface
server := osin.NewServer(osin.NewServerConfig(), &TestStorage{})

// Authorization code endpoint
http.HandleFunc("/authorize", func(w http.ResponseWriter, r *http.Request) {
	resp := server.NewResponse()
	if ar := server.HandleAuthorizeRequest(resp, r); ar != nil {

		// HANDLE LOGIN PAGE HERE

		ar.Authorized = true
		server.FinishAuthorizeRequest(resp, r, ar)
	}
	osin.OutputJSON(resp, w, r)
})

// Access token endpoint
http.HandleFunc("/token", func(w http.ResponseWriter, r *http.Request) {
	resp := server.NewResponse()
	if ar := server.HandleAccessRequest(resp, r); ar != nil {
		ar.Authorized = true
		server.FinishAccessRequest(resp, r, ar)
	}
	osin.OutputJSON(resp, w, r)
})

http.ListenAndServe(":14000", nil)

Example Access

Open in your web browser:

http://localhost:14000/authorize?response_type=code&client_id=1234&redirect_url=http%3A%2F%2Flocalhost%3A14000%2Fappauth%2Fcode
