oauth2lib

Pre-baked library for using golang.org/x/oauth2 with facebook, github, google, etc. Compatible with any framework that uses the standard golang http.Handler

Overview

1. You fill out an oauth2.Config sans Endpoint
2. Pass the config along with a callback function to the appropriate provider
3. You callback is invoked when the user authorizes a request
   • from your callback you can do whatever you want; redirect the user, create a new session for them, etc

Simple Example

In this example, we redirect the user to /blah once they've successfully authorized via Facebook

func main() {
	config := &oauth2.Config{
		ClientID:     "your-facebook-app-id",
		ClientSecret: "your-facebook-app-secret",
		RedirectURL:  "your-oauth2-callback-endpoint",
	}

	handler := oauth2lib.Facebook(config, authorize)
	http.Handle("/oauth2/facebook", handler)

	http.ListenAndServe(":8000", nil)
}

func authorize(c *oauth2lib.Context) {
	fmt.Println("access token is", c.Token.AccessToken)
	http.Redirect(c.Response, c.Request, "/blah", http.StatusTemporaryRedirect)
}
