Question

我一直在使用以下代码 1）检查是否有facebook会话打开，如果打开获取名称（第一个和最后一个）和电子邮件。该页面是facebook_signup.php 2）如果没有，请使用facebook注册并将会话保存到signup.php中的数据库中。

以下是facebook_signup.php的代码。

<?php

// Awesome FB APP 
// Name: MyAPP 

require_once 'facebook-php-sdk-master/src/facebook.php';// this line calls our       facebook.php file that is the 
//core of PHP facebook API
// Create our Application instance.

$facebook = new Facebook(array(

'appId' => 'xxxxx',

'secret' => 'xxxxx',

'cookie' => true,

 )); // all we are doing is creating an array for facebook to use with our 

 $user = $facebook->getUser();
 echo $user;
 //app id and app secret in and setting the cookie to true
 if($user){
 try {
 $user_profile = $facebook->api('/me');
 } catch (FacebookApiException $e) {
 error_log($e);
 $user=null;

 } // this code is saying if the session to the app is created use 
 }
 //the $me as a selector for the information or die

 ?>

  <script>

     FB.init({ 

        appId:'250941738370233', cookie:true, 

        status:true, xfbml:true 

     });

     FB.Event.subscribe('auth.login', function(response) {

    window.location.reload(); //will reload your page you are on

  });

  </script> 

  <? } ?> 
  </body>
  </html>

有人可以告诉我为什么我登录Facebook时仍然无法获得用户登录会话。同样在值字段中，意外的结果即将到来（出错了）。对这件事情不熟悉并试图将用户会话（姓名和电子邮件）保存到数据库中。
