我有一个大问题，我试图解决好几天但无法解决。

我得到了以下代码来登录 Facebook 上的应用程序。一切都运行良好，除了当页面重新加载时（使用 window.location.reload();）它没有更新 API /me，所以它总是返回登录按钮。

例外：当我单击 F5 刷新页面时，它运行良好

如果有人可以提供帮助，将不胜感激

谢谢

 <?php

require 'facebook.php';

 // Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId'  => 'xxxxxxxxxxxx',
'secret' => 'xxxxxxxxxxxxx',));

$user = $facebook->getUser();

 // login or logout url will be needed depending on current user state.
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
 } else {
 $loginUrl = $facebook->getLoginUrl();
 }

 $user = $facebook->getUser();
 // Session based API call.
if ($user) {
  try {
    $me = $facebook->api('/me');
} catch (FacebookApiException $e) {
    echo '<pre>'.htmlspecialchars(print_r($e, true)).'</pre>';
     $user = null;
}
}

FB.login不返回，这response.status是返回的FB.getLoginStatus。另请参阅FB.login文档以获取更多信息。
