      function(response){
      console.log(response);
  });
  </code></pre>
  
  <p>which should be like:</p>
  
  <pre><code>GET https://graph.facebook.com/oauth/access_token?
          client_id=YOUR_APP_ID
         &amp;client_secret=YOUR_APP_SECRET
         &amp;redirect_uri=uri
  </code></pre>

  <pre><code>code: 1
  message: "Missing authorization code"
  type: "OAuthException"
