php - 无法连接到 graph.facebook.com 端口 443 : Network unreachable

Question

<?php
session_start();

//included file and use

$app_id = 'xxx';
$app_secret = 'xxx';
FacebookSession::setDefaultApplication($app_id, $app_secret);
$helper = new FacebookRedirectLoginHelper("`http://example/facebook4.0`/", $app_id, $app_secret);
try 
{
    $session = $helper->getSessionFromRedirect();
}
catch(FacebookRequestException $ex) { } 
catch(Exception $ex) { }

$loggedIn = false;

if (isset($session))
{
    if ($session) 
        {
            $loggedIn = true;
            try {                     //logged here and get data
                $user_profile = (new FacebookRequest(
                $session, 'GET', '/me'
                ))->execute()->getGraphObject(GraphUser::className());

               print_r($user_profile); //print data

            } 
            catch(FacebookRequestException $e)  {
                echo "Exception occured, code: " . $e->getCode();
                echo " with message: " . $e->getMessage();
            }   
        }
}

if(!$loggedIn)  //if user is not online // get link and add scope
{
    $loginUrl = $helper->getLoginUrl(array('public_profile','email'));
    echo "<a href='$loginUrl'>Login With Facebook</a>";
}
else
{
    print_r($user_profile); //logout link is generated here 
    echo '<br><br><a href="index.php">Logout</a>'; //print to sceen
}

?>

我已将域名设置为 localhost，并将站点 URL 设置为 http://localhost/。 我也试过 http://localhost:80 , http://mydomainname:80 (改变主机)

这是我在响应中得到的错误:

Answer 1

我知道这是一个老问题，OP 可能已经找到了解决方案。我在使用 Laravel Socialite 时也遇到了同样的问题插入。

为了后代，我想在这里发布解决方案。此 question 中解释了该问题:域 graph.facebook.com 解析为某些网络可能未配置为路由的 IPV6 地址。您可以请求 cURL 将 IP 地址解析为其 IPV4 值。将选项 CURLOPT_IPRESOLVE 设置为 CURL_IPRESOLVE_V4。

对于 socialite 插件，我们必须修改 FacebookProvider.php 以包含附加选项。

编辑

更具体地说，Socialite 使用 GuzzleHttp，我们需要将其作为参数传递给 GuzzleHttp Client 方法:

'curl' => [ CURLOPT_IPRESOLVE => CURL_IPRESOLVE_V4]
