Description: I have created a Facebook app. I have given site URL as "http://localhost:8088/fb/" After saving the changes. Now I want to get user id so that I can access user's information on Facebook.
下面是我的代码:

require 'facebook.php';
$facebook = new Facebook(array(
'appId' => 'xxxxxxxxxxx',
'secret' => 'xxxxxxxxxxxxxxxxxx',
));
$user = $facebook->getUser();
echo $user;

<?php if($user )
{
?>
<a href="<?php echo $logoutUrl; ?>">Logout</a>

推荐答案
我对PHP不太了解，但原因可能是其中之一:
I don't know much about PHP but the reason might be one of these:
- 您未对您的应用程序进行身份验证.
- 您正在从本地主机运行该应用程序，并在域或其他域中提供了图API的名称.
- 您的访问令牌已过期.
