Laravel/Lumen |发送事件失败

Question

这是我第一次使用 Laravel/Lumen 中的事件。

我实际上正在使用 Lumen，并且我试图在新用户注册时分派一个 Mailable 实例，以便在后台发送电子邮件。

我相信我已经设置好了，但是我一直收到这个错误...

Type error: Argument 1 passed to Illuminate\Mail\Mailable::queue() must implement interface Illuminate\Contracts\Queue\Factory, instance of Illuminate\Queue\DatabaseQueue given

我实际上无法在错误消息本身中看到问题出在哪里，例如没有行号。

但是，这是我的代码...

AuthenticationContoller.php

$this->dispatch(new NewUser($user));

NewUser.php

<?php

namespace App\Mail;

use App\Models\User;
use Illuminate\Mail\Mailable;
use Illuminate\Bus\Queueable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;

class NewUser extends Mailable implements ShouldQueue
{
    use Queueable, SerializesModels;

    protected $user;

    public function __construct(User $user)
    {
         $this->user = $user;
    }

    /**
      * Build the message.
      *
      * @return $this
      */
      public function build()
      {
         return $this->view('test')->to('test@test.com', 'Test')
        ->from('test@test.com', 'test')->replyTo('test@test.com', 'test')
        ->subject('Welcome to the blog!');
      }
}

Answer 1

我运行遇到了同样的问题。 Lumen 和 Illuminate/Mailer 似乎不能很好地协同工作。

但是我在 a Github thread 中找到了一个非常简单的修复方法。

基本上，您只需在 app/Providers 目录中创建一个新的服务提供商。

MailServiceprovider.php

<?php

namespace App\Providers;

use Illuminate\Mail\Mailer;
use Illuminate\Mail\MailServiceProvider as BaseProvider;

class MailServiceProvider extends BaseProvider
{
    /**
     * Register the Illuminate mailer instance.
     *
     * @return void
     */
    protected function registerIlluminateMailer()
    {
        $this->app->singleton('mailer', function ($app) {
            $config = $app->make('config')->get('mail');

            // Once we have create the mailer instance, we will set a container instance
            // on the mailer. This allows us to resolve mailer classes via containers
            // for maximum testability on said classes instead of passing Closures.
            $mailer = new Mailer(
                $app['view'], $app['swift.mailer'], $app['events']
            );

            // The trick
            $mailer->setQueue($app['queue']);

            // Next we will set all of the global addresses on this mailer, which allows
            // for easy unification of all "from" addresses as well as easy debugging
            // of sent messages since they get be sent into a single email address.
            foreach (['from', 'reply_to', 'to'] as $type) {
                $this->setGlobalAddress($mailer, $config, $type);
            }

            return $mailer;
        });

        $this->app->configure('mail');

        $this->app->alias('mailer', \Illuminate\Contracts\Mail\Mailer::class);
    }
}

然后您只需在 bootstrap/app.php 中注册此服务提供商，而不是通过添加以下行的默认服务提供商：

$app->register(\App\Providers\MailServiceProvider::class);
