我配置了 Symfony 和 FOSHttpCacheBundle(遵循FOSHttpCache 文档中的 Varnish 配置说明)。
我向控制器添加了一个操作,该操作test
在响应 HTTP 标头中添加了一个标记:
<?php
use FOS\HttpCacheBundle\Configuration\Tag;
class MyController extends Controller
{
/**
* @Route("/test1", name="acme_my_test1")
* @Tag("test")
*/
public function test1Action()
{
return new Response(rand(0, 1000));
}
}
但是,每当我调用/test1
URL 时,数字都会改变,显示缓存未激活。请注意,我的应用程序不使用任何 cookie,并且我可以测试标头是否已发送到 Varnish(由于该指令X-Cache-Tags
,它会在对浏览器的响应中将其剥离)。vlc_deliver
配置中有什么我会错过的吗?Varnish 和 Nginx 都运行在同一台服务器上。
这是我的 Symfonyconfig.yml
文件中与 HTTP 缓存相关的配置:
framework:
trusted_hosts: ~
trusted_proxies: [127.0.0.1]
fos_http_cache:
proxy_client:
varnish:
servers: 127.0.0.1:80
base_url: mywebsite.localhost.com
tags:
enabled: true
和清漆配置/etc/varnish/default.vcl
:
vcl 4.0;

.host = "127.0.0.1";
.port = "8080";
