无法连接到graph.facebook.com端口443:连接被拒绝

Question

我是FB图形API的新手,我尝试在我的网站中包含FB登录,我从他们的网站上关注官方FB登录教程,但登录后我收到以下错误:

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

的login.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-callback.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']
}
?>

例如帆布-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.
}
?>

我已经在堆栈和谷歌搜索,但我找不到任何解决方案

Hostinger的免费服务器不允许连接到客户服务部门提到的Fb SDK.
