Swiftmailer：邮件“默认”不存在

Question

我有一个 Symfony 4.1 项目，我希望能够在开发环境中发送邮件，但是当我执行命令 php bin/console swiftmailer:email:send 时出现此错误：

在 NewEmailCommand.php 第 76 行：邮件程序“默认”不存在。

我认为这是我的配置有问题，因为我的印象是它在 services.yaml 中找不到我的默认邮件程序的密钥。

packages/dev/swiftmailer.yaml：

swiftmailer:
    mailers:
        no_reply:
            delivery_address: test@yopmail.com

packages/swiftmailer.yaml：

swiftmailer:
    default_mailer: no_reply
    mailers:
        no_reply:
            url: '%env(MAILER_URL)%'
            spool: { type: memory }

BaseController.php：

<?php

declare(strict_types = 1);

namespace App\Controller;

use Swift_Mailer;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;

abstract class BaseController extends AbstractController
{
    /**
     * @var Swift_Mailer
     */
    protected $swiftMailer;

    public function __construct(Swift_Mailer $swiftMailer)
    {
        $this->swiftMailer           = $swiftMailer;
    }
}

我所有的控制器都从 BaseController.php 扩展

输出

php bin/控制台调试：容器

你知道我的问题可能来自哪里吗？

Answer 1

查看php bin/console debug:container列出的服务列表，没有名为swiftmailer.mailer.default的服务，请使用swiftmailer.mailer或swiftmailer.mailer.no_reply。

Answer 2

我解决了这个错误

swiftmailer:
  default_mailer: default
  mailers:
    default:
      url: '%env(MAILER_URL)%'
      spool: { type: memory }
