cURL：操作在0毫秒后超时 [英] cURL: Operation timed out after 0 milliseconds

问题描述

cURL给我错误：

Operation timed out after 0 milliseconds with 0 out of 0 bytes received

特别是，0毫秒部分是可疑的...

In particular, the "0 milliseconds" part is suspicious...

我的初始化代码：

$curl = curl_init($requestUrl); // private URL not published
curl_setopt($curl, CURLOPT_FRESH_CONNECT, true);
curl_setopt($curl, CURLINFO_HEADER_OUT, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curl, CURLOPT_HTTPHEADER, 
  array("Content-Type: application/xml", "Accept: application/xml"));
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_TIMEOUT, 20);
curl_setopt($curl, CURLOPT_FAILONERROR, false);
curl_setopt($curl, CURLOPT_HTTP200ALIASES, range(400, 599));
curl_setopt($curl, CURLOPT_SSLVERSION, 3);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);

超时似乎设置正确，可能有什么关系？

The timeout seems correctly set, what may be related it?

推荐答案

当尝试通过https连接时，我有同样的问题。问题是与ssl版本。
这对我很有用：

I had the same issue, when tried to connect via https. Problem was with ssl version. This worked well for me:

$ch=curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSLVERSION, 3);
