我有 Facebook 的 Flash 游戏。昨天它工作正常，成功地将数据插入数据库，但现在当我尝试启动我的应用程序/游戏时出现错误：Fatal error: Uncaught OAuthException: An active access token must be used to query information about the current user. thrown in /home/padekime/domains/padekime.eu/public_html/images/base_facebook.php on line 1254

这是我的代码：

<?php
$request = $_REQUEST["signed_request"];
list($encoded_sig, $load) = explode('.', $request, 2);
$fbData = json_decode(base64_decode(strtr($load, '-_', '+/')), true);
if (!empty($fbData["page"]["liked"]))
{ ?>
<?php

require_once('images/Facebook.php');

  $facebook = new Facebook(array(
    'appId'  => 'yyyyyyyyyyyyyyyyyyyyyyy',
    'secret' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxx',
  ));

  # Get User ID
  $user = $facebook->getUser();
$user_profile = $facebook->api('/me');
$coded = $_REQUEST['code'];
$name = "".$user_profile['name']."";

  if ($user) {
    try {


?>

<?php } ?>

我不知道怎么了，昨天它工作了，这个echo $facebook->getAccessToken();返回的访问令牌，但今天应用程序不起作用。你可以帮帮我吗？谢谢你。

access_token 仅在一个小时内有效，除非您已将其转换为长期访问令牌。如果access_token返回错误，建议让用户重新登录或使用JavaScript SDK为用户获取新的token（可以使用functionFB.getLoginStatus()函数）

如果用户更改了密码，access_token 也可能过期。
