在 EventServiceProvider 里注册（app/Providers/EventServiceProvider.php）

protected $listen = [
        Registered::class => [
            SendEmailVerificationNotification::class,
        ],
        'App\Events\Test' => [
            'App\Listeners\EventListener',
        ],
    ];

使用命令行来生成事件与监听器

$ php artisan event:generate

此时将生成两个文件

1、App/Events/Test.php（事件）

编辑事件

<?php

namespace App\Events;

use App\Models\User;
use Illuminate\Broadcasting\Channel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;

class Test
{
  use Dispatchable, InteractsWithSockets, SerializesModels;

  /**
 * Create a new event instance. * * @return void
 */  public function __construct($id)
 {  
     echo '触发事件成功！---------'.$id;
     $this->id = $id;
  }

  /**
 * Get the channels the event should broadcast on. * * @return \Illuminate\Broadcasting\Channel|array
 */  public function broadcastOn()
 {  return new PrivateChannel('channel-name');
  }
}

2、app/Listeners/EmailVerified.php（监听器）

编辑监听器

<?php

namespace App\Listeners;

use App\Events\Test;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;

class EventListener
{
  /**
 * Create the event listener. * * @return void
 */  public function __construct()
 {  //
  }

  public function handle(Test $event)
 {  
     echo '监听成功！监听值：'.$event->id;
 }
}

在控制器中触发事件

public function test1()
{
 event(new Test('11111111'));
 return '测试事件系统';
}

常用命令

php artisan event:generate
php artisan make:event UserRegisteredEvent
php artisan make:listener SendMailListener --event="UserRegisteredEvent"
