使用事件侦听器重定向所有“未找到路由 404 Not Found - NotFoundHttpException"； [英] Redirect with Event Listener for all "No route found 404 Not Found - NotFoundHttpException"

问题描述

如何在事件侦听器中触发重定向到特定路由器?

How can I trigger redirect to a specific router in event listener?

有很多例子，但我找不到一个关于GetResponseForExceptionEvent"的例子.例如，当我将 @roter 作为参数传递时 $this->router.... 似乎不起作用.

There are many examples but I couldn't find one for "GetResponseForExceptionEvent". For exampe, when I pass @roter as an argument $this->router.... doesn't seem to be working so on.

我检查了这些，但我可能错过了一些东西:

I checked these but I probably missed something:

• 显示特定路由而不是错误页面 (404) - Symfony2
• symfony2:挂钩 NotFoundHttpException 以进行重定向
• Symfony2 事件监听器重定向?
• Symfony2:在页面加载事件侦听器中获取路由
• 如果用户已登录则重定向

service.yml

services:
    kernel.listener.kernel_request:
        class: BookingAdminBundleEventListenerErrorRedirect
        tags:
            - { name: kernel.event_listener, event: kernel.exception, method: onKernelException }

事件监听器:

namespace BookingAdminBundleEventListener;

use SymfonyComponentHttpKernelEventGetResponseForExceptionEvent;
use SymfonyComponentHttpKernelExceptionNotFoundHttpException;

class ErrorRedirect
{
    public function onKernelException(GetResponseForExceptionEvent $event)
    {
        $exception = $event->getException();

        if ($exception instanceof NotFoundHttpException) {
            // redirect to '/' router or '/error'
            //$event->setResponse(...........);
        }
    }
} 

推荐答案

您有 2 个选择:

• 使用事件监听器
• 使用匹配所有不存在的路由并在控制器中触发操作的路由.

让我知道这是否有效.

注意:查看Symfony2 事件侦听器重定向

1 将路由器传递给您的事件侦听器:

1 Pass the router to your event listener:

kernel.listener.kernel_request:
       class: BookingAdminBundleEventListenerErrorRedirect
       arguments:
           router: "@router"
       tags:
           - { name: kernel.event_listener, event: kernel.exception, method: onKernelException }

2 使用监听器内的路由器重定向用户:

2 Use the router within the listener to redirect users:

namespace BookingAdminBundleEventListener;

use SymfonyComponentHttpKernelEventGetResponseForExceptionEvent;
use SymfonyComponentHttpKernelExceptionNotFoundHttpException;
use SymfonyComponentHttpFoundationRedirectResponse;
use SymfonyBundleFrameworkBundleRoutingRouter;

class ErrorRedirect
{
    /**
     * Holds Symfony2 router
     *
     *@var Router
     */
    protected $router;

    /**
     * @param Router
     */
    public function __construct(Router $router)
    {
        $this->router = $router;
    }


    public function onKernelException(GetResponseForExceptionEvent $event)
    {
        $exception = $event->getException();

        if ($exception instanceof NotFoundHttpException) {

            /** Choose your router here */
            $route = 'route_name';

            if ($route === $event->getRequest()->get('_route')) {
                return;
            }

            $url = $this->router->generate($route);
            $response = new RedirectResponse($url);
            $event->setResponse($response);

        }
    }
}

选项 2

你可以创建一个特殊的路由来匹配所有不存在的路由；然后，您可以在您选择的控制器中以您想要的方式处理重定向，这里是 PageNotFoundController:

Option 2

You can create a special route that will match all routes that don't exist; You can then handle the redirect the way you want within the controller of your choice, here PageNotFoundController:

1 在 app/config/routing.yml 末尾

1 At the end of app/config/routing.yml

pageNotFound:
    pattern:  /{path}
    defaults: { _controller: AcmeDemoBundle:PageNotFound:pageNotFound, path: '' }
    requirements:
        path: .*

2

<?php

namespace AcmeDemoBundleController;

use SymfonyBundleFrameworkBundleControllerController;
use SymfonyComponentHttpFoundationJsonResponse;
use SymfonyComponentHttpFoundationResponse;
use SymfonyComponentHttpKernelExceptionNotFoundHttpException;

class PageNotFoundController extends Controller
{

    public function pageNotFoundAction()
    {
        // redirect the way you want

    }

}
