symfony 5-未调度事件 [英] symfony 5 - event not being dispatched

问题描述

提交订单后，我使用事件订阅者来处理一些操作.

I use an event subscriber to handle some actions when my order form is submitted.

问题是我的活动没有分发，但是symfony能够找到他，因为他告诉我我的OrderEvent :: ORDER_CREATE是孤立的.

Problem my event is not being dispached but symfony is able to find him because he tells me that my OrderEvent::ORDER_CREATE is orphan.

我希望通过 die('Hello you from subscription''s; )来停止执行，但并非如此.

I excpected that execution was stopped with die('Hello you from subscriber'); but it's not.

控制器

public function commanderPanierAction(Request $request, SelectionWeb $selectionWeb, TableLumineuse $tableLumineuse, EventDispatcherInterface $eventDispatcher)
{
    // DO PREVIOUS STUFF

    $Order = new Order();
    $OrderForm = $this->createForm(OrderForm::class, $Order);
        
    if ($request->isMethod('POST')) {
      $OrderForm->handleRequest($request);

      if ($OrderForm->isSubmitted() && $OrderForm->isValid()) {
          // OrderForm is valid proceed
          $eventDispatcher->dispatch(
              new OrderEvent($Order),
              OrderEvent::ORDER_CREATE
          );
      }
   } 

OrderEvent

OrderEvent

<?php

namespace App\Event;

use App\Entity\Order;
use Symfony\Contracts\EventDispatcher\Event;

class OrderEvent extends Event
{
    public const ORDER_CREATE = 'order.created';

    protected $order;

    public function __construct(Order $order)
    {
        $this->order= $order;
    }

    public function getOrder(): Order
    {
        return $this->order;
    }
}

OrderSubscriber

OrderSubscriber

<?php

namespace App\EventSubscriber;

use App\Event\CommandeWebEvent;
use App\Service\SelectionWeb\SelectionWeb;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;


class OrderSubscriber implements EventSubscriberInterface
{
    private $entityManager;

    private $selectionWeb;

    public function __construct(EntityManagerInterface $entityManager, SelectionWeb $selectionWeb)
    {
        $this->entityManager = $entityManager;
        $this->selectionWeb = $selectionWeb;
    }

    public static function getSubscribedEvents()
    {
        return [
            OrderEvent::ORDER_CREATE => [
                // The higher the number, the earlier the method is called.
                ['processOrder', 10],
                ['notifyOrder', -10]
            ]
        ];
    }

    public function processOrder(OrderEvent $event)
    {
        // TODO
        die('Hello you from subscriber');
    }

    public function notifyOrder(OrderEvent $event)
    {
        // TODO
    }
}

编辑

找到的唯一解决方法(向@nikserg致谢)是将订户注入控制器动作(订户具有依赖性)，然后在 services.yaml 中将我的订户注册为服务，最后使用 $ eventDispatcher-> addSubscriber($ subscriber); 在 $ eventDispatcher-> dispatch(new OrderEvent($ Order)，OrderEvent :: ORDER_CREATE);

The only workaround found (thx to @nikserg) is to inject subscriber into controller action (subscriber has dependencies) then register my subscriber as service in services.yaml finaly use $eventDispatcher->addSubscriber($subscriber); before $eventDispatcher->dispatch(new OrderEvent($Order),OrderEvent::ORDER_CREATE);

对于这么简单的任务，所有这些东西似乎真的很复杂

It seems all that stuff is really complex for a task as simple as that

EDIT2

我发现了另一种无需使用 $ eventDispatcher-> addSubscriber($ subscriber); 且仅使用 $ eventDispatcher-> dispatch(new OrderEvent($ Order)); 仅当我在 services.yaml 中将订户配置为服务时，但是为什么symfony在services.yaml中确实需要此信息?认为src/中的所有内容都可以用作服务.

I found an another way I'm able to execute my subscriber without usage of $eventDispatcher->addSubscriber($subscriber); and only with $eventDispatcher->dispatch(new OrderEvent($Order)); only if I configure my subscriber as service in services.yaml but why symfony does need this information in services.yaml ? Thought that everything in src/ is avaible to be used as service..

# makes classes in src/ available to be used as services
# this creates a service per class whose id is the fully-qualified class name
App\:
    resource: '../src/*'
    exclude: '../src/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'

# If I add those It works
App\EventSubscriber\OrderSubscriber:
    autowire: true

EDIT3

我的OrderSubscriber已加载到容器中，为什么我应该将其显式设置为正在执行?我不知道发生了什么事

My OrderSubscriber is loaded into container so why I should set it explicitly to being execute ? I can't figure out what's going on

php bin/console debug:container
---------------------------------------- ---------------------------------------
Service ID                               Class name
---------------------------------------- ----------------------------------------
App\EventSubscriber\OrderSuscriber App\EventSubscriber\OrderSuscriber

如果我明确设置 OrderSubscriber ，则有两个实例进入容器.为什么symfony明确执行一组而不是使用 resource:'../src/*'

If I set my OrderSubscriber explicitly there is two instances of it into container. Why symfony execute one set explicitly and not the one set with resource: '../src/*'

推荐答案

首先，我要感谢大家的宝贵时间，让我对我的问题表示歉意，原因是我写了 OrderSuscriber 而不是打字错误 OrderSubscriber 这就是为什么我的容器中有2个服务，以及为什么定义的服务明确起作用的原因.

First I want to thank you all for your time and let me apologize my problem was due to a typo I wrote OrderSuscriber instead of OrderSubscriber that's why there was 2 services into my container and why defined service explicitly was working.
