具有Symfony反向代理的FOSHttpCache

Question

因此，我嘗試使用默認的Symfony HttpCache配置FOSHttpCacheBundle（最新版本^ 2.0） 。

根據文檔，這是我的AppCache.php的內容：

<?php

use FOS\HttpCache\SymfonyCache\CacheInvalidation;
use FOS\HttpCache\SymfonyCache\EventDispatchingHttpCache;
use FOS\HttpCache\SymfonyCache\DebugListener;
use FOS\HttpCache\SymfonyCache\CustomTtlListener;
use FOS\HttpCache\SymfonyCache\PurgeListener;
use FOS\HttpCache\SymfonyCache\RefreshListener;
use FOS\HttpCache\SymfonyCache\UserContextListener;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\HttpCache\HttpCache;
use Symfony\Component\HttpKernel\HttpKernelInterface;
use Symfony\Component\HttpKernel\HttpCache\StoreInterface;
use Symfony\Component\HttpKernel\HttpCache\SurrogateInterface;

class AppCache extends HttpCache implements CacheInvalidation
{
    use EventDispatchingHttpCache;

    /**
     * Overwrite constructor to register event listeners for FOSHttpCache.
     */
    public function __construct(
        HttpKernelInterface $kernel,
        StoreInterface $store,
        SurrogateInterface $surrogate = null,
        array $options = []
    ) {
        parent::__construct($kernel, $store, $surrogate, $options);

        $this->addSubscriber(new CustomTtlListener());
        $this->addSubscriber(new PurgeListener());
        $this->addSubscriber(new RefreshListener());
        $this->addSubscriber(new UserContextListener());
        if (isset($options['debug']) && $options['debug']) {
            $this->addSubscriber(new DebugListener());
        }
    }

    /**
     * Made public to allow event listeners to do refresh operations.
     *
     * {@inheritDoc}
     */
    public function fetch(Request $request, $catch = false)
    {
        return parent::fetch($request, $catch);
    }
}

現在根據Symfony的文檔 ，從而使高速緩存代理只是一個設定app.php文件如下的物質（取消注釋最后一行）：

$kernel = new AppKernel('prod', false);
$kernel->loadClassCache();
$kernel = new AppCache($kernel);

這給了我一個不錯的選擇：

PHP消息：PHP捕獲的致命錯誤：傳遞給Symfony的\\元器件參數2 \\ HttpKernel \\ HttpCache \\ HttpCache :: __構建體（）必須的Symfony \\組件的實例\\ HttpKernel \\ HttpCache \\ StoreInterface，沒有給出，稱為在/ PHP / API /current/web/app.php上線11和上線78在/php/api/current/vendor/symfony/symfony/src/Symfony/Component/HttpKernel/HttpCache/HttpCache.php定義

這使得給予HttpCache類的構造非常有意義。

所以問題是，是不是最新的文檔，還是僅僅是我遺漏了一些明顯的東西？

use Symfony\Component\HttpKernel\HttpCache\Store;

$kernel = new AppKernel('dev', true);
$kernel->loadClassCache();
$store = new Store('app/cache');
$kernel = new AppCache($kernel, $store);
