Facebook API导入相册仅适用于我，不适用于其他用户？

Question

我正在创建一个网站，用户通过他们的Facebook帐户登录后将访问我的网站上的相册和图片。我必须在我的网站上放置什么代码才能做到这一点。 我能够获得所有登录的用户的所有常规信息，但不是他们的漫游和图片。 所有的代码工作正常，只有当我登录我的Facebook的身份证，然后它给我所有的信息图片和相册也。我希望这个东西适用于所有的用户。 我已经从Facebook和堆栈溢出阅读大量的文档资料，但我不能找到答案， 这是我demo Link

这里是我的代码：

require '../php-sdk/facebook.php'; 

// Create our Application instance (replace this with your appId and secret). 
$facebook = new Facebook(array(
    'appId' => 'xxxxxxxxxxx', 
    'secret' => 'xxxxxxxxxxxxxxxxxxxxxx', 

)); 

// Get User ID 
$user = $facebook->getUser(); 
$user_id = $user; 
$access_token = $facebook->getAccessToken(); 


$SESSION['token']="CAAHk9LIIji4BAMLZCNFVMDSNEZCZCc5zfb80c8Nq4wrLZBqY56o3ZARrO3FZC9qPWXHdYpH5jZBaaADWsZBKZAdViKA5eQlKcFK579SOlOq2CXms8ZAqGZAJdXsUZAH2ZCtqPZASn3A8ZB7VXFxb4WFjPJTPUNDQlZBZCtqHcJNZA3TRozriLDCjjRdsPp5Bad9Mu1J9CdGJQZD"; 
$SESSION['token']= $access_token; 
echo $url = "https://graph.facebook.com/me/photos?access_token=" . $SESSION['token']; 
$photos = json_decode(file_get_contents($url)); 

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

// Login or logout url will be needed depending on current user state. 
if ($user) { 
    $logoutUrl = $facebook->getLogoutUrl(); 
} else { 
    $statusUrl = $facebook->getLoginStatusUrl(); 
    $loginUrl = $facebook->getLoginUrl(); 
} 


?> 

<?php if ($user): ?>

我认为你需要询问用户允许使用他们的图片。您需要将权限数组传递给获取登录URL的函数。您需要的许可是“user_photos”。
