Question

我正在尝试连接到facebook API

require_once '/composer/vendor/autoload.php';

$fb = new Facebook\Facebook([
  'app_id' => 'xxxx', // obviously, I've put my app ID in here 
  'app_secret' => 'xxxx', // and my app secret in here
  'default_graph_version' => 'v2.4',
]);

要执行以下请求，如果我是对的，应该向我提供该URL的份额数：

$target = 'http://stackoverflow.com';

$node = $fb->get('/?id='.urlencode($target).'&fields=share')->getGraphNode();

$shareCount = $node['share']['share_count'];

但是，我收到以下错误：

Fatal error:
Uncaught exception 'Facebook\Exceptions\FacebookSDKException' 
with message 'couldn't connect to host' 
in /backend/composer/vendor/facebook/php-sdk-v4/src/Facebook/HttpClients/FacebookCurlHttpClient.php:83 

Stack trace:

Facebook\HttpClients\FacebookCurlHttpClient->send('https://graph.f...', 'GET', '', Array, 60)

#4 {main} thrown in /backend/composer/vendor/facebook/php-sdk-v4/src/Facebook/HttpClients/FacebookCurlHttpClient.php on line 83

根据我的阅读，可能是我不允许在我的服务器上使用cURL，但是我在其他地方使用它并且它有效，所以我认为问题不是来自这里。 / p>

知道我做错了什么？

由于

Facebook PHP SDK“无法连接到主机”
