我想构建一个Web应用程序，使用Facebook API + PHP从我拥有的封闭组中获取提要，喜欢和评论
我看到我可以使用这个Graph API界面获取信息，开始阅读facebook文档，并开始认为我不能真正这样做： https://developers.facebook.com/docs/public_feed/
但仍有这样的： https://developers.facebook.com/docs/graph-api/reference/v2.2/group/feed
和我无法找到获取群组Feed的功能！ 所以也许我不能正常工作而且我错过了一些东西。
虽然在Facebook API界面上运行它确实有用！ - （https://developers.facebook.com/tools/explorer/145634995501895/）
在较旧的帖子中，很多stackoverflowers都建议我使用Graph API + PHP，它完全
Is it possible to get a facebook feed to a closed group that I belong to but do not own?
这是我现在的代码，准备工作了。

$helper = new FacebookRedirectLoginHelper($redirect_url);

if ( isset($session) ){
// Create request object, execute and capture responce
$request = new FacebookRequest($session, 'GET', '/15013584710049696319/feed'); //Represents a request that will be made against the Graph API.
//From the response - get graph object
$response = $request->execute(); //Returns a Facebook\FacebookResponse from this request, from which a strongly-typed result can be retrieved.
//Throws an exception if the request fails. If the error is returned from Facebook,
//as opposed to a networking issue, a Facebook\FacebookRequestException is thrown.
$graph = $response->getGraphObject(); //Returns the result as a GraphObject. If specified, a strongly-typed subclass of GraphObject is returned.
var_dump($graph);
//use graph object methods to get user details
//$name = $graph->getname();
//echo "Hi $name";

else {
echo '<a href="' . $helper->getLoginUrl() . '">Login with Facebook</a>';
}

这是我在var转储中得到的：
object(Facebook\GraphObject)[4]
protected 'backingData' =>
array (size=0)
