Facebook API-使用JSSDK登录，在后端使用php SDK

Question

I'm working on this web application that I use the FB JSSDK to log the user in, on some other page in the back end I want to do some functions like:

$user_profile = $facebook->api('/me');

For this first I need to do this:

$config = array(
          'appId' => 'xxx',
          'secret' => 'xxx',
          'cookie' => true,
          'fileUpload' => false, 
          'allowSignedRequest' => false,
      );

      $facebook = new Facebook($config);


      return $facebook;

I've already logged in once with JSSDK, is the a way to read the cookie or somehow use the php functions without logging again?

Answer 1

$facebook->getMetadataCookie()

would return all the contents of authentication cookie.

But you better explain what do you need it for.
