Symfony Messenger 中没有配置处理程序

Question

我想实现 Messenger 异步处理程序并能够在 Redis 中对一些任务进行排队，但由于某些原因我不能。

这是我的全局配置：

PHP 7.3.16
Symfony 4.4.7
信使 4.4
Redis 5.0.3
Predis 1.1

我试着遵循这个指南：

https://symfony.com/doc/4.4/messenger.html

一切都是来自文档的 copy/paste，除了我用命令替换了我的控制器。

这个调度命令似乎有效：

php bin/console app:dispatch-command

^ Symfony\Component\Messenger\Envelope^ {#5465 -stamps: []
-message: App\Message\SmsNotification^ {#5475 -content: "Look! I created a message!" } }

这个命令returns没有配置处理程序:

php bin/console debug:messenger

Messenger

=========

第二个命令returns在尝试使用消息时出错

php bin/console messenger:consume async

      #message: "The first argument must be an instance of "Symfony\Component\Messenger\RoutableMessageBus"."

有人可以帮我吗？

干杯！

更新

我尝试按照 the doc 中的说明手动路由我的处理程序：

# config/services.yaml
App\MessageHandler\SmsNotificationHandler:
    tags: [messenger.message_handler]

但这并没有改变什么。

我还检查了我的消息和消息处理程序是否已注册为服务，它是:

php bin/console debug:container App

[70 ] App\Message\SmsNotification

[71 ] App\MessageHandler\SmsNotificationHandler

Answer 1

我仍然不知道是什么原因导致了这个问题，但我刚刚通过安装一个全新的 Symfony 4.4.7 项目并覆盖它成功地解决了它。

我还发现 swiftmailer 已被 mailer 取代，twig-bundle 被 twig-pack 取代，但仅适用于新项目，而 composer 不会注意到现有安装（即使使用 composer update/upgrade/recipes。它可能是我遇到问题的原因，但我不确定。

第 1 步：创建一个新的 Symfony 4.4.7 项目

composer create-project symfony/website-skeleton newProj ^4.4.7
sudo chown -R $USER:www-data 
cd /newProj

第 2 步：用我的 git 项目覆盖

git init
git remote add origin $url_of_clone_source
git fetch origin
git checkout -b master --track origin/master

第 3 步：安装供应商并替换过时的依赖项

composer install
composer remove symfony/swiftmailer
composer require symfony/mailer
composer remove symfony/twig-bundle
composer require symfony/twig-pack

第 4 步：检查 Messenger

$ php bin/console debug:messenger

Messenger
=========

messenger.bus.default
---------------------

 The following messages can be dispatched:

 ---------------------------------------------------------- 
  App\Message\SmsNotification                               
      handled by App\MessageHandler\SmsNotificationHandler  
  Symfony\Component\Mailer\Messenger\SendEmailMessage       
      handled by mailer.messenger.message_handler           
 ----------------------------------------------------------
