php - 使用 cURL PHP 与命令行 cURL 清除 Varnish 缓存

Question

目前，我们在一台服务器上有多个虚拟主机。我正在尝试通过不涉及exec命令的PHP进行缓存清除。我可以通过发出以下命令行命令来清除Varnish Cache中的单个文件:

curl -X PURGE -H "Host: domain.com" http://127.0.0.1/test.html

我正在尝试将此命令复制到PHP。我生成了以下内容:

if (isset($_POST['PurgeURL']))
{
    $purgeurl = $_POST["PurgeURL"];
    $varnishurl = "http://127.0.0.1" . $purgeurl ;
    $varnishhost = 'Host: ' . $_SERVER['SERVER_NAME'];
    $varnishcommand = "PURGE";
    $curl = curl_init($varnishurl);
    curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $varnishcommand);
    curl_setopt($curl, CURLOPT_ENCODING, $varnishhost);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, false);
    $result = curl_exec($curl);
    curl_close($curl);

我正在发布/test.html。

我收到以下答复:

Error 200 Purged.

Purged.

但是，此文件不会清除。有任何想法吗？

这是请求的 Varnish 日志:

Answer 1

您没有发出正确的“Host:” HTTP header ，因此我认为以下几行之一存在问题:

$varnishhost = 'Host: ' . $_SERVER['SERVER_NAME'];

curl_setopt($curl, CURLOPT_ENCODING, $varnishhost);
