Question

我正在尝试使用PHP SDK从Facebook页面读取评级以在外部显示。我已经拥有一个长实时访问令牌，并且能够使用它来提取主页面数据，但是当我尝试访问/ratings端点时，我只收到一个空的Array ( )

class FacebookReviews
{
    protected $session;
    protected $page;
    protected $ratings;
    protected $appId;
    protected $appSecret;

    function __construct($appId = null, $appSecret = null)
    {
        session_start();
        $this->appId = '123456789123456';
        $this->appSecret = '1234567890abcdefghijklmnopqrstuv';

        Facebook\FacebookSession::setDefaultApplication($this->appId, $this->appSecret);
        $this->session = new Facebook\FacebookSession('LONG LIVE ACCESS TOKEN I GENERATED ON THE GRAPH API');

        try {
          $this->session->validate();
        } catch (Facebook\FacebookRequestException $ex) {
          // Session not valid, Graph API returned an exception with the reason.
          echo $ex->getMessage();
        } catch (\Exception $ex) {
          // Graph API returned info, but it may mismatch the current app or have expired.
          echo $ex->getMessage();
        }

        try {
            $this->page = (new Facebook\FacebookRequest($this->session, 'GET', '/123456789123456/ratings'))->execute()->getGraphObject()->asArray();
        } catch(Facebook\FacebookRequestException $e) {
            echo "Exception occured, code: " . $e->getCode();
            echo " with message: " . $e->getMessage();
        }
    }

    public function result()
    {
        return $this->page;
    }
}

$reviews = new FacebookReviews();

print_r($reviews->result());

如果我从请求uri中删除/ratings，它会返回数据，但正如我在那里提到的那样，它不起作用。

我从自己的帐户生成了长期访问令牌，该帐户具有对该页面的管理员权限

Facebook Open Graph Graph Object返回空对象
