facebook图形API不返回事件

Question

我正在尝试使用图形API调用来返回登录到我的应用程序的用户的事件。然而，$ event始终为空，虽然我自己创建了一堆事件，任何人都可以帮忙吗？

这里是我的代码登录到事件API调用：

require_once('AppInfo.php'); 

// Enforce https on production 
if (substr(AppInfo::getUrl(), 0, 8) != 'https://' && $_SERVER['REMOTE_ADDR'] != '127.0.0.1') { 
    header('Location: https://'. $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']); 
    exit(); 
} 

// This provides access to helper functions defined in 'utils.php' 
require_once('utils.php');  
require_once('sdk/src/facebook.php'); 

$facebook = new Facebook(array(
    'appId' => AppInfo::appID(), 
    'secret' => AppInfo::appSecret(), 
    'sharedSession' => true, 
    'trustForwarded' => true, 
)); 

$user_id = $facebook->getUser(); 
if ($user_id) { 
    try { 
    // Fetch the viewer's basic information 
    $basic = $facebook->api('/me'); 
    } catch (FacebookApiException $e) { 
    // If the call fails we check if we still have a user. The user will be 
    // cleared if the error is because of an invalid accesstoken 
    if (!$facebook->getUser()) { 
     header('Location: '. AppInfo::getUrl($_SERVER['REQUEST_URI'])); 
     exit(); 
    } 
    } 

    // This fetches some things that you like . 'limit=*" only returns * values. 
    // To see the format of the data you are retrieving, use the "Graph API 
    // Explorer" which is at https://developers.facebook.com/tools/explorer/ 
    $likes = idx($facebook->api('/me/likes?limit=4'), 'data', array()); 

    // This fetches 4 of your friends. 
    $friends = idx($facebook->api('/me/friends?limit=4'), 'data', array()); 

    // And this returns 16 of your photos. 
    $photos = idx($facebook->api('/me/photos?limit=16'), 'data', array()); 

    // Fetch the event information 
// $events = idx($facebook->api('/me/events?limit=5'), 'data', array()); 
    $events = $facebook->api('/me/events','GET'); 
    print("11111"); 
    if($events == null) print("empty");

我认为没有登录代码在你的榜样，你一定要在用户登录？见PHP SDK“用法”：https://github.com/facebook/facebook-php-sdk

无论如何，我只是想这在我的项目之一，我得到同样的呼叫的用户事件，但我需要的权限“user_events”：

$facebook->getLoginUrl(array('scope' => 'user_events'));
