Single Sign On : Stuck on progressing image in jsconnect - php

Question

what i want to achieve is, user login in my wordpress website and also login on vanilla forum, i have installed jsconnect plugin in vanilla forum, and using the php's jsconnect library from following location jsConnectPHP
Here is my code:
require_once('functions.jsconnect.php');
$clientID = "1501569466";
$secret = "xxxxxxxxxxxxxxxxxxxxxx";
$userD = array();
if( isset($_POST['log']) ){
$data = array();
$data['user_login'] = $_POST['u_user'];
$data['user_password'] = $_POST['u_pass'];
$data['remember'] = TRUE;
$user = wp_signon($data, FALSE);
if(!is_wp_error($user)){
$userD['uniqueid'] = $user->ID;
$userD['name'] = $user->user_login;
$userD['email'] = $user->user_email;
$userD['photourl'] = '';
$secure = true;
WriteJsConnect($user, $_GET, $clientID, $secret, $secure);
$redirect = "http://localhost/vanilla/entry/jsconnect?client_id={$clientID}";
echo "<script>document.location.href='".$redirect."';</script>";
}
}
when the user login on wordpress i redirect it to jsconnect url in vanilla where i just found only a progress image, and can't figure out where is the problem..

Answer 1

jsconnect authentication url expects jsonp array like the following:
test({"email":"test#test.com",
"name":"testuser",
"photourl":"",
"uniqueid":1234,
"client_id":"12345678",
"signature":"XXXX"})
You authorization url you specify inside jsconnect should see this output to process further. In fact I am stuck at that point. I could see vanilla forum when loaded gets this input but no login happens.
