title: Golang GAE - Federated Login examples
body: <p>I'm trying to implement Federated Login using Google App Engine Go SDK, but the only examples I can find on the subject are about <a href="https://developers.google.com/appengine/articles/openid" rel="nofollow">how to do this in Python and Java</a>. I understand that I need to call <a href="https://developers.google.com/appengine/docs/go/users/reference#LoginURLFederated" rel="nofollow">this function</a> to get the URL, but I'm not sure about the parameters to pass. Can someone provide examples of Federated Login in GAE Golang for a few major platforms (Facebook, Twitter, etc)?</p>
