Question

我想获得使用curl的网站内容，这是Cloudflare的服务背后。以下代码适用于大多数网站，但不是Cloudflare背后的代码，甚至在cloudflare.com上都失败了。你能帮助我解决可能导致这种行为的原因吗？

我有以下配置：

PHP Version 5.6.31
卷曲：7.54.0

代码：

$ch = curl_init(); 

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT ,5); 
curl_setopt($ch, CURLOPT_TIMEOUT, 5); //timeout in seconds
curl_setopt($ch, CURLOPT_URL, "https://cloudflare.com"); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
//curl_setopt($ch, CURLOPT_SSLVERSION, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($ch, CURLOPT_VERBOSE, true);

$fp = fopen(dirname(__FILE__).'/errorlog.txt', 'w');
curl_setopt($ch, CURLOPT_STDERR, $fp);

// $output contains the output string 
$result = curl_exec($ch); 

if ($result === FALSE) {
    printf("cUrl error (#%d): %s<br>\n", curl_errno($ch),
           htmlspecialchars(curl_error($ch)));
}

fclose($fp);
curl_close($ch);

结果是：

cUrl error (#28): Operation timed out after 5000 milliseconds with 0 out of 0 bytes received

错误日志：

* Rebuilt URL to: https://cloudflare.com/

* TCP_NODELAY set

卷曲操作超时，收到0个字节中的0个
