Symfony2：ESI setMaxAge缓存 [英] Symfony2: ESI setMaxAge Cache

问题描述

我有一个控制器，其控制器动作用

I have a Controller whose Action is rendered in twig with

{{render_esi（con​​troller（'MyWebsiteBundle：Element：header'））） }}

动作本身如下：

/**
     * @return Response
     */
    public function headerAction()
    {
        $currentLocale = $this->getCurrentLocale();

        $response = $this->render('MyWebsiteBundle:Element:header.html.twig', array(
            'currentLocale' => $currentLocale,
            'myTime' => time()
        ));
        $response->setPublic();
        $response->setSharedMaxAge(3600);

        return $response;
    }

重新加载浏览器时， myTime 每次都会更改。

When I reload my Browser, the "myTime" changes everytime.

如何使用 setShardeMaxAge（），以便仅在MaxAge过期后才渲染Twig？ / p>

How can I use setShardeMaxAge(), so that the Twig is only renderd after the MaxAge is expired?

推荐答案

在Symfony2中，您需要执行一些操作才能激活esi缓存。

In Symfony2 there's a few things you need to do in order to activate esi caching.

1）在 app / config / config.yml 中，确保您激活了带片段路径的esi。

1) In app/config/config.yml make sure you activated esi, with a fragments path.

framework:
    esi: { enabled: true }
    fragments: { path: /_proxy }

2）用AppCache对象包装内核

2) Wrap the kernel with the AppCache object

// web/app.php
$kernel = new AppCache($kernel); 

3）设置AppCache配置

3) Set up the AppCache configuration

// app/AppCache.php
use Symfony\Bundle\FrameworkBundle\HttpCache\HttpCache;

class AppCache extends HttpCache
{
    protected function getOptions()
    {
        return array(
            'debug'                  => false,
            'default_ttl'            => 0,
            'private_headers'        => array('Authorization', 'Cookie'),
            'allow_reload'           => false,
            'allow_revalidate'       => false,
            'stale_while_revalidate' => 2,
            'stale_if_error'         => 60,
        );
    }
}

关于您的问题是否正在缓存您的回复和唯一的问题是，每次刷新页面时都会重新加载。确保配置 allow_reload 属性设置为false。

About your issue if it is caching your response and the only problem is that it's reloading every time you refresh the page. make sure the configuration allow_reload property is set to false.
