[go-nuts] [ANN] OSIN - Complete OAuth2 provider (server) library

Hello,

I created an OAuth2 server library in Go, that aims to be a complete
implementation of the RFC.

https://github.com/RangelReale/osin

It already implements most of the core spec, but has not been in production
yet, so it should be considered beta quality.

As I am new to Go (who isn't?), I am still not sure about library design
patterns, like configurations and callbacks. Any comments on the library
interface are highly welcomed.

This is a sample of the implementation, there are 3 working examples on the
examples directory.

import "github.com/RangelReale/osin"

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

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

         // HANDLE LOGIN PAGE HERE

         ar.Authorized = true
         server.FinishAuthorizeRequest(resp, r, ar)
     }
     output.Output(resp, w, r)
})

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

http.ListenAndServe(":14000", nil)
