Cant get token from janrain

I set up the authentication window, according to the introduction janrain, but as the callback come, there is no token. What could be the problem?

Here is the magic code:

...

$rpxApiKey = '95c8d032db3db656e7716749552ff12c82f7开发者_开发问答108f';  

if(isset($_POST['token'])) { 

echo "hello";

  /* STEP 1: Extract token POST parameter */
  $token = $_POST['token'];

...

but hello is not appearing.

1. Go to https://rpxnow.com/ and login.
2. Go to "Deployment" -> "Domain & Settings".
3. Add your URL to the whitelisted domains, e.g.: *.your-url.com
