Question

我在两个docker站点site1.example.com和api.example.com上遇到问题。这两个站点都通过docker托管在我的本地计算机上。我试图通过curl向api.example.com发出请求，如下所示：

$curl_handle=curl_init();
  curl_setopt($curl_handle,CURLOPT_URL,'http://api.example.com');
  curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,1000);
  curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($curl_handle, CURLOPT_HEADER, 1);
  curl_setopt($curl_handler, CURLOPT_FOLLOWLOCATION, true);
  curl_setopt($curl_handle, CURLOPT_PROXY, true);
  curl_setopt($curl_handle, CURLOPT_VERBOSE, true);
  curl_setopt($curl_handle, CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($curl_handle, CURLOPT_SSL_VERIFYHOST, false);
  $result = curl_exec($curl_handle);
  if($result === false) {
     $error = curl_error($curl_handle);
     print_r($error);
  }
  print_r($result);
  curl_close($curl_handle);

发生了什么事

如果我关闭CURLOPT_PROXY，则会收到连接被拒绝的错误。
启用代理后，我得到一个结果= false，但没有给出结果错误消息
这是我的docker日志：

[27-Nov-2018 18:23:04] WARNING: [pool www] child 352 said into stderr: "* Rebuilt URL to: http://api.example.local/?is_deleted=0"

但是相同的代码可以在生产环境中正常工作。我在php：7.2-fpm上，知道使用docker的curl有什么问题吗？

PHP CURL无法在2个Docker站点之间连接
