当从应用程序管理员以外的帐户访问Facebook PHP web应用程序时不工作

我有一个非常简单的PHP应用程序，检索用户&朋友RSVPd事件使用FQL。它使用最新的PHP SKD。当我登录并身份验证为创建应用程序的帐户时，代码工作完美，但如果我登录并身份验证为其他人，则会出现"未知错误"。

这是我的代码的登录部分

$config = array();
$config['appId'] = $validId;
$config['secret'] = $validSecret;
$facebook = new Facebook($config);
$uid = $facebook->getUser();
    // get the url where to redirect the user
$location = "". $facebook->getLoginUrl(array('scope' => 'user_events, friends_events'));
// check if we have valid user
if ($uid) {
    try {
        $fb_user_profile = $facebook->api('/me');   
    } catch (FacebookApiException $e) {
        $fb_user_id = NULL;
        // seems we don't have enough permissions
        print '<script language="javascript" type="text/javascript"> top.location.href="'. $location .'"; </script>';
        // kill the code so nothing else will happen before user gives us permissions
        die();
    }
} else {
    // seems our user hasn't logged in
    print '<script language="javascript" type="text/javascript"> top.location.href="'. $location .'"; </script>';
    // kill the code so nothing else will happen before user gives us permissions
    die();
}
print "Authenticated ". $fb_user_profile['name']." <a href='logout.php'>Logout</a><br>";

这是我的代码的FQL部分

$param  =   array(
  'method'    => 'fql.query',
  'query'     => $validFqlQuery,
  'callback'  => '',
  'access_token' => $facebook->getAccessToken()
 );
echo "<br>Working...";
 $fqlResult   =   $facebook->api($param); 
print_r($fqlResult);
