Symfony Messenger 中沒有配置的處理程序

Question

我想實現 Messenger 異步處理程序並能夠在 Redis 中對一些任務進行排隊，但由於某種原因我不能。

這是我的全局配置：

• PHP 7.3.16
• Symfony 4.4.7
• 信使 4.4
• Redis 5.0.3
• Predis 1.1

我嘗試遵循本指南：

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

一切都是文檔的復制/粘貼，除了我用命令替換了我的 controller。

這個調度命令似乎有效：

php bin/console app:dispatch-command

^ Symfony\Component\Messenger\Envelope^ {#5465 -stamps: []
-message: App\Message\SmsNotification^ {#5475 -content: "看！我創建了一條消息！" } }

此命令不返回任何已配置的處理程序：

php bin/console debug:messenger

信使

第二條命令在嘗試使用消息時返回錯誤

php bin/console messenger:consume async

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

有人可以幫幫我嗎？

干杯!

更新

我嘗試按照文檔中的說明手動路由我的處理程序：

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

但它什么也沒改變。

我還檢查了我的消息和消息處理程序是否已注冊為服務，它是：

php bin/console debug:container App

[70] 應用\消息\短信通知

[71] 應用\消息處理程序\短信通知處理程序

Answer 1

我仍然不知道是什么導致了這個問題，但我只是通過安裝一個全新的 Symfony 4.4.7 項目並覆蓋它來成功解決它。

我還發現 swiftmailer 被 mailer 取代，twig-bundle 被 twig-pack 取代，但僅適用於新項目，作曲家沒有通知現有安裝（即使使用作曲家更新/升級/食譜。這可能是我的問題，但我不確定。

第一步：新建Symfony 4.4.7工程

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 項目覆蓋

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

第 3 步：安裝供應商並替換過時的依賴項

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

第4步：檢查信使

$ 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           
 ----------------------------------------------------------
