我们使用Symfony(Sulu)和Varish作为反向代理,使用基于标签的无效(Xkey),其工作方式与预期一致.现在,我们希望在我们的网站上对动态块使用ESI,与"主"缓存生存期分开.

但每次完全缓存网页时,即使在硬刷新/清除浏览器缓存或使用新浏览器之后,页面也总是显示第一个缓存条目.

使用带有PHP(端口:9000)、Nginx(端口:8000)和Varish(端口:8081)的Docker设置

我们已在Symfony中启用了ESI:

framework:
...
    esi: true
    fragments: { path: /_fragment }

并在我们的Twig模板中提供render_esi:

navbar.html.twig

...
            {{ render_esi(controller('App\\Controller\\Website\\LoginButtonController::renderEsiLoginButton')) }}
            <div class="navbar-main__toggler"></div>
        </div>

LoginButtonController

class LoginButtonController extends AbstractController
{
    public function renderEsiLoginButton(): Response
    {
        $response = $this->render('esi/_login_button.html.twig', ['random_nr' => rand()]);

        $response->setMaxAge(10);
        $response->setSharedMaxAge(10);
        $response->setPublic();

        return $response;
    }
}

_login_button.html.twig

<div class="navbar-main__action-account">
    <div class="account__dropdown">
        <a href="#" class="account__user">{{ random_nr }}</a>
        ...
    </div>
</div>

我们的fos_http_cache配置:

fos_http_cache:
    tags:
        enabled: true
        response_header: xkey
        max_header_value_length: 1024
    proxy_client:

            use_kernel_dispatcher: true

    user_context:
        enabled: true
        role_provider: true
#        user_hash_header: 'X-User-Context-Hash'
        hash_cache_ttl: 900

和Sulu http缓存:

when@prod: &prod
    sulu_http_cache:
        debug:
            enabled: false
        tags:
            enabled: true
        cache:
            max_age: 240
            shared_max_age: 480
        proxy_client:
            symfony:
                enabled: false
            varnish:
                enabled: true
                servers: [ '%env(VARNISH_SERVER)%' ]
                tag_mode: purgekeys

在使用cURL时,我们还可以正确地看到esi:include标记

curl -i -X GET 'http://localhost:8000/en' -H 'Surrogate-Capability: ESI/1.0:

<span class="navbar-main__action-search-button"></span>

<esi:include src="/_fragment?_hash=HAz3Ym5wXab4GXTRKnq8oUR3WwnGqUpprL0niBc%2BEwg%3D&_path=_format%3Dhtml%26_locale%3Den%26_controller%3DApp%255CController%255CWebsite%255CLoginButtonController%253A%253ArenderEsiLoginButton" onerror="continue" />

<div class="navbar-main__toggler"></div>

但网页仍被完全缓存,即使在硬刷新/清除浏览器缓存或使用新浏览器后,页面始终显示第一个随机数.直到我们完全清除瓦尼什的藏身之处.

我们遗漏了什么?

    call fos_tags_xkey_recv;
    call fos_user_context_recv;
    call sulu_recv;

推荐答案

从表面上看,你做的一切都是对的.但是,一些有针对性的varnishlog个命令将让我们更好地理解Varish是如何缓存各种片段的.

我需要您将以下命令的输出发送给我:

sudo varnishlog -g request -q "ReqUrl eq '/'"

我的假设是这个问题发生在主页上.如果不是这样,请更改varnishlog命令中的筛选器.

It's important that you run this command on an empty cache!

当Varish执行各种获取操作时,我们可以查看日志(log)中的TTL个标记.这将告诉我们Varish如何决定每个片段的TTL(通过在VCL代码中设置的TTL,或者通过Cache-Control头).

日志(log)还将各种ESI子请求作为单独的日志(log)事务返回,从而更容易理解在什么情况下发生了什么.

请把日志(log)输出放在你的原始问题中,我会帮你弄清楚发生了什么.

更新

我没有在您的(后端)请求中看到Surrogate-Capability头.如果没有该标头,symfony将不会触发Surrogate-Control标头,从而启用Varish中的ESI处理.尽管在您的VCL代码中看到了Surrogate-Capability.

然而,就在您设置标题之前,我在VCL代码中看到了call fos_user_context_backend_response;call sulu_backend_response;call sulu_recv;.很可能会在那里执行一条返回语句,绕过您的头.

我的建议是将set req.http.Surrogate-Capability = "abc=ESI/1.0";移到vcl_recv子 routine 的开头.

只需确保设置了头并且逻辑不会被其他调用绕过即可.

解决此问题的一种简单方法是将此逻辑移到vcl_backend_fetch子 routine ,因为设置标头与获取相关,而不是与接收请求相关.以下是VCL代码:

sub vcl_backend_fetch {
    set bereq.http.Surrogate-Capability = "abc=ESI/1.0";
}
