Question

我正在使用Facebook登录我的网站：

<?php
/*
 * login_with_facebook.php
 */

    require('http.php');
    require('oauth_client.php');

    $client = new oauth_client_class;
    $client->debug = false;
    $client->debug_http = true;
    $client->server = 'Facebook';
    $client->redirect_uri = 'http://'.$_SERVER['HTTP_HOST'].
        dirname(strtok($_SERVER['REQUEST_URI'],'?')).'/login_with_facebook.php';

    $client->client_id = ''; $application_line = __LINE__;
    $client->client_secret = '';

    if(strlen($client->client_id) == 0
    || strlen($client->client_secret) == 0)
        die('Please go to Facebook Apps page https://developers.facebook.com/apps , '.
            'create an application, and in the line '.$application_line.
            ' set the client_id to App ID/API Key and client_secret with App Secret');

    /* 
     * API permissions
     */
    $client->scope = 'email';
    if(($success = $client->Initialize()))
    {
        if(($success = $client->Process()))
        {
            if(strlen($client->access_token))
            {
                $success = $client->CallAPI(
                    'https://graph.facebook.com/me', 
                    'GET', array(), array('FailOnAccessError'=>true), $user);
            }
        }
        $success = $client->Finalize($success);
    }
    if($client->exit)
        exit;
    if($success)
    {
?>

<?php
    }

?>

当我点击＆＃34;使用Facebook登录＆＃34;在示例网站上，登录Facebook后出现此错误;

OAuth客户端错误

错误：无法打开OAuth访问令牌网址：111无法连接到主机＆＃34; graph.facebook.com＆＃34;

Facebook App设置正常，具有正确的客户端ID和客户端密钥，MySQL查询设置。

为什么会发生这种情况的任何想法？
