【问题描述】：
我正在尝试获取用户最喜欢的电影和其他详细信息以及 FB JS SDK。以下对我来说是正确的。我曾尝试使用 ajax 来删除页面重新加载。但我没有找到为什么在登录按钮出现之前页面被重新加载两次。并且在用户输入登录凭据并单击登录按钮后，在数据出现之前页面重新加载了两次。 我想删除这个多重页面重新加载。有人可以检查代码并使其更容易吗？
登录.php：
<?php
session_start();
$appId = '66';
$appSecret = 'sdsds3'; // Facebook App Secret
$return_url = 'http://yoursite.com/connect_script/'; //path to script folder
$fbPermissions = 'publish_stream,email'; //more permissions : https://developers.facebook.com/docs/authentication/permissions/
