我正在使用下面的代码来检查用户是否登录到 Facebook。
<?php
// Awesome FB APP
// Name: MyAPP
require_once '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' => '250941738370233',
'secret' => 'xxx',
'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
?>
但是 $user 每次都响应 0 。在这一点上我被严重卡住了。有人可以帮我吗?
