php – 通过facebook graph API检索facebook用户的邮政编码

$facebook = new Facebook(array(
            'appId' => APP_ID,'secret' => APP_SECRET,));

$user = $facebook->getUser();
//$login_url = $facebook->getLoginUrl(array( 'scope' => 'email'));
$login_url   = $facebook->getLoginUrl(
           array(
               'scope'         => 'email,publish_stream,user_birthday,user_location,user_work_history,user_about_me,user_hometown'
           )
   );
//get user basic description
//$userInfo           = $facebook->api("/$user");

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

这里我得到$user_profile数组,它包含其他所有邮政编码信息.但我允许这样做.有没有办法从Facebook获取邮政编码.
