title: Facebook share dialog (URL Redirection) get response/feedback on redirect uri (redirect_uri)
body: <p>I'm using Facebook's share dialog with URL Redirection as shown here:
  <a href="https://developers.facebook.com/docs/sharing/reference/share-dialog" rel="nofollow">https://developers.facebook.com/docs/sharing/reference/share-dialog</a></p>
  
  <p>Everything works fine, but the problem I'm having is that I need to get some kind of response or feedback in the redirect uri to know whether the user has published or cancelled the share.
  I thought the <code>post_id</code> would be included as query string when redirecting. But this is not the case... I just get a trailing <code>#_=_</code></p>
  
  <p>So... is it possible to get somehow the response or some kind of feedback when redirecting to know whether the user has actually published the post or not?</p>

    <p>Please also note that I cannot use the FB.ui API as the callback is
    not working at all when using it inside a web mobile view.</p>

  <p>Thanks!</p>
