Symfony2調用內核超過1次

Question

我對symfony2有問題。 當加載頁面symfony加載內核超過1次時，這里就是轉儲。

有人遇到這個問題嗎？ 版本2.6.9

Answer 1

不，您正在讀取錯誤的日志。 這不是Symfony多次加載內核，而是Symfony向所有感興趣的訂戶通知內核事件。 很好，您不必擔心。

當然，每次加載頁面時，您可能會有幾個請求，因此您必須將其簽出。

1. 您應該排除子請求（內部請求或重定向）。 請參閱http://symfony.com/doc/current/cookbook/service_container/event_listener.html#request-events-checking-types 。

2. 您可能要排除資產等。

這是我使用的實際偵聽器改編而成的示例：

public function onKernelRequest(GetResponseEvent $event)
{
    // Exclude subrequests
    if ($event->getRequestType() != HttpKernelInterface::MASTER_REQUEST)
    {
        return;
    }

    // Exclude assets
    $route = $event->getRequest()->get('_route');
    if (strpos($route, "_") === 0) {
        return;
    }
}
