Question

我们目前在服务器上有多个虚拟主机。我试图通过PHP执行缓存清除，不涉及exec命令。我可以通过发出以下命令行命令清除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。我已经生成了以下内容：

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);

我发布了/test.html。

我收到以下回复：

Error 200 Purged.

Purged.

但是文件没有清除。有什么想法吗？

以下是请求的清漆日志：

Answer 1

您没有发出正确的“Host：”HTTP标头，因此我认为以下某行存在问题：

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

curl_setopt($curl, CURLOPT_ENCODING, $varnishhost);

使用cURL PHP与命令行cURL进行清漆缓存清除
