}
else {
echo("The state does not match. You may be a victim of CSRF.");
}
?>
在这里，当我打印$user参数时，它不显示任何内容。我无法找出错误 以下是通过PHP API获取facebook用户提要的代码，我使用facebook PHP SDK获取提要：
<?php
require_once('src/facebook.php');
$facebook = new Facebook(array(
'appId' => '304784726296644',
'secret' => '0d68eaf6dfe5d99cec8f3559b1212b15',
'cookie' => true,
));
$uid = $facebook->getUser();
$me = null;
if ($uid) {
try {
$me = $facebook->api('/me');
$feed = $facebook->api('/me/feed/');
} catch (FacebookApiException $e) {
error_log($e);
}
}
//4. login or logout
if ($uid) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$loginUrl = $facebook->getLoginUrl();
}
?>
