facebook php SDK를 사용하여 facebook 프로필 사진에 액세스하는 방법은 무엇입니까?

Question

다음 코드를 사용하여 사용자 프로필 사진에 액세스하고 있습니다. ..

<?php 
session_start(); 
include 'facebook-php-sdk/autoload.php'; 

use Facebook\FacebookRedirectLoginHelper; 
use Facebook\FacebookRequest; 
use Facebook\FacebookSession; 

FacebookSession::setDefaultApplication('XXXX', 'XXXX'); 
$helper = new FacebookRedirectLoginHelper('http://localhost/oauth/login.php'); 
try { 

    $session = $helper->getSessionFromRedirect(); 

} catch(FacebookRequestException $ex) { 
// When Facebook returns an error 

} catch(\Exception $ex) { 
// When validation fails or other local issues 

} 
if ($session) { 
    // Logged in 


    // $request = new FacebookRequest($session, 'GET', '/me'); 
    // $response = $request->execute(); 
    // $graphObject = $response->getGraphObject(); 


    // var_dump($graphObject->asArray()); 

    $request = new FacebookRequest(
     $session, 
     'GET', 
     '/me/picture' 
    ); 
    $response = $request->execute(); 
    $graphObject = $response->getGraphObject(); 

    var_dump($graphObject->asArray()); 
} 

?>

내가 요청

<?php 
session_start(); 

include 'facebook-php-sdk/autoload.php'; 

use Facebook\FacebookRedirectLoginHelper; 
use Facebook\FacebookRequest; 
use Facebook\FacebookSession; 

$permissions = array(
    'email', 
    'user_location', 
    'user_birthday', 
    'user_photos', 
    'public_profile' 
); 

/* Set the public and secret keys */ 
FacebookSession::setDefaultApplication('XXX', 'XXX'); 

$helper = new FacebookRedirectLoginHelper('http://localhost/oauth/login.php'); 
$loginUrl = $helper->getLoginUrl($permissions); 
// Use the login url on a link or button to redirect to Facebook for authentication 

?> 
    <a href="<?php echo $loginUrl; ?>">Login using facebook</a> 

<?php 

?>

을 생성하는 방법이며,이 페이지의 사용자가 리디렉션입니다

나는 항상 "array (0) {}"-> 빈 배열을 출력합니다. 나는이 코드에 무슨 문제가 있는지 파악하지 못했습니다. 로그인 URL이나 그래프 쿼리에 문제가있는 동안 일부 허가를 놓쳤습니까?

그리고 여기에 내가 몇 가지 기본 동작을 예상 $ 응답 객체

의 vardump이다하지만 쿼리가 성공하려면 추가 옵션이 필요한 것으로 나타났다. 너무 $ 응답 및 $ graphObject의

$request = new FacebookRequest(
      $session, 
      'GET', 
      '/me/picture', 
      array (
       'redirect' => false, 
       'type' => 'large' 
      ) 
     );
