php - 无法连接到 graph.facebook.com 端口 443 : Connection refused

Question

我是 FB 图形 API 的新手，我尝试在我的网站中包含 FB 登录，我按照他们网站上的官方 FB 登录教程进行操作，但登录后出现以下错误:

Failed to connect to graph.facebook.com port 443: Connection refused

登录.php

<?php
session_start();
require_once __DIR__ . '/fbsdk/src/Facebook/autoload.php';

$fb = new Facebook\Facebook([
'app_id' => 'xxx',
'app_secret' => 'xxx',
'default_graph_version' => 'v2.3',
// . . .
]);

$helper = $fb->getRedirectLoginHelper();
$permissions = ['public_profile', 'email']; // optional
$loginUrl = $helper->getLoginUrl('http://-myserver-/login-callback.php',    $permissions);

echo '<a href="' . $loginUrl . '">Log in with Facebook!</a>';
?>

登录回调.php

<?php
session_start();
require_once __DIR__ . '/fbsdk/src/Facebook/autoload.php';

$fb = new Facebook\Facebook([
'app_id' => 'xxx',
'app_secret' => 'xxx',
'default_graph_version' => 'v2.3',
// . . .
]);



$helper = $fb->getRedirectLoginHelper();
try {
$accessToken = $helper->getAccessToken();
} catch(Facebook\Exceptions\FacebookResponseException $e) {
// When Graph returns an error
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
// When validation fails or other local issues
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}

if (isset($accessToken)) {
// Logged in!
$_SESSION['facebook_access_token'] = (string) $accessToken;

// Now you can redirect to another page and use the
 // access token from $_SESSION['facebook_access_token']
}
?>

示例-canvas-app.php

<?php
session_start();
require_once __DIR__ . '/fbsdk/src/Facebook/autoload.php';

$fb = new Facebook\Facebook([
'app_id' => 'xxx',
'app_secret' => 'xxx',
'default_graph_version' => 'v2.3',
// . . .
]);



$helper = $fb->getCanvasHelper();
try {
$accessToken = $helper->getAccessToken();
} catch(Facebook\Exceptions\FacebookResponseException $e) {
// When Graph returns an error
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
// When validation fails or other local issues
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}

if (isset($accessToken)) {
// Logged in.
}
?>

我已经在 stack 和 google 中搜索过，但找不到任何解决方案

正如其客户服务所提到的，Hostinger 的免费服务器不允许连接到 Facebook 的 SDK。
