Question

我的数据库存在一个很大的问题，即我在Facebook上的应用程序的许可。

当用户打开应用程序（index.php）并接受权限时，应用程序转到另一个页面（game.php）...当game.php打开时，脚本检查数据库以查看是否Facebook的ID已经存在，如果没有数据库成为用户。

当game.php第一次打开时，页面会生成此错误：

OAuthException: An active access token must be used to query information about the current user.
Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in game.php on line 67 check1Error: Duplicate entry '0' for key 'UIDfacebook' account

可能是因为facebook的ID尚未准备好在数据库中保存，为什么？权限是接受...如果我刷新页面，页面将正常工作，数据库保存ID，用户名....

INDEX.PHP（REQUEST）

<?php
require('client/facebook.php');

$app_id = '***';
$app_secret = '***';
$canvas_page = "https://apps.facebook.com/***";
$canvas_url = "****";

$code = $_REQUEST['code'];

if(!$code){
$display= 'page';
$scope= 'offline_access, publish_stream, user_about_me, user_likes, email'; 
$redirect_url = 'game.php';
$oauth_url    = 'https://www.facebook.com/dialog/oauth?canvas=1&client_id='.$app_id.'&display='.$display.'&redirect_uri='.urlencode($redirect_url).'&scope='.$scope;
$config = array('appId'  => $app_id,'secret' => $app_secret,'cookie' => true,'domain' => true);
$facebook_client = new Facebook($config);

echo "<script type=\"text/javascript\">top.location.href = \"".$oauth_url."\";</script>";
}
?>

GAME.PHP

有人知道会发生什么事吗？

非常感谢

编辑：

我尝试将此脚本用于GAME.PHP：

<?php
require 'client/facebook.php';
$app_id = "aaa";
$secret = "aaa";
$app_url = "http://app.facebook.com/aaa/";

// Create our Application instance
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $secret,
));

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

//Do we have a user?
if(!$user) {
    $loginUrl = $facebook->getLoginUrl(array('redirect_uri'=> $app_url));
    //redirect the url to prompt for login and permissions
    echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
    } else {
        try{
            //Proced knowing you have a logged in user who's autenticated
            $user_profile = $facebook->api('/me');
            $name = $user_profile['name'];
            $id = $user_profile['id'];
            $first_name = $user_profile['first_name'];
            $last_name = $user_profile['last_name'];
            $link = $user_profile['link'];
            $username = $user_profile['username'];
            $gender =  $user_profile['gender'];
            $locale = $user_profile['locale'];


        } catch (FacebookApiException $e) {
            echo ($e);
            $user = null;
        }
}
echo $username;
echo $id;
echo $user_profile;
?>

但是第一次，错误是类似的？

OAuthException: Error validating access token: The session was invalidated explicitly using an API call.

如果我刷新页面，问题就会消失......

错误Facebook应用程序，权限接受，但......第一次不起作用
