Question

我只需要简单易用的Facebook应用。我为此买了ssl而且我不想要太多费用。

如果用户允许应用，则会写出他的姓名和性别以及他/她的朋友性别。

我的应用在用户允许该应用后无法重定向。我无法修复它所以只需要基本的应用程序，而不需要重定向。

ı使用此代码，但它不起作用。需要纠正：

require_once("facebook.php");
$facebook = new Facebook(array(
    'appId'  => '***',
    'secret' => '***',
  'scope'  => 'manage_pages,offline_access,publish_stream,user_photos'
));

$user = $facebook->getUser();

if ($user) {
  try {
    // Proceed knowing you have a logged in user who's authenticated.
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    $user = null;
  }
}

if ($user) {
  $logoutUrl = $facebook->getLogoutUrl();
} else {
  $loginUrl = $facebook->getLoginUrl();
}
