事件类通常被保存在 app/Events 目录下，而它们的处理程序则被保存在 app/Handlers/Events 目录下。

leokim\app\Events\LeokimTestEvent.php

<?php

namespace App\Events;

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

class LeokimTestEvent
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

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

1.创建事件

php artisan make:event LeokimTestEvent

2.创建事件handle

leokim\app\Handlers\Events\LeokimTestEventHandler.php

<?php
namespace App\Handlers\Events;
use App\Events\LeokimTestEvent;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldBeQueued;

class LeokimTestEventHandler{
    public function __construct()
    {
    }

    public function handle(LeokimTestEvent $event)
    {
        echo '<br>事件触发测试';
    }
}

3.在EventServiceProvider中注册

leokim\app\Providers\EventServiceProvider.php

<?php

namespace App\Providers;

use Illuminate\Support\Facades\Event;
use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;

class EventServiceProvider extends ServiceProvider
{
    /**
     * The event listener mappings for the application.
     *
     * @var array
     */
    protected $listen = [
        'App\Events\Event' => [
            'App\Listeners\EventListener',
        ],
        'App\Events\LeokimTestEvent' => [
            'App\Handlers\Events\LeokimTestEventHandler',
        ],
    ];

    /**
     * Register any events for your application.
     *
     * @return void
     */
    public function boot()
    {
        parent::boot();

        //
    }
}

4.在controller中触发

<?php

namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Events\LeokimTestEvent;

class LeokimController extends Controller
{
    protected $leo;

    function __construct($leo)
    {
        $this->leo = $leo;
    }

    function index(){
        echo '123';
        event(new LeokimTestEvent());
    }

    function test($id){
        return $this->leo.$id;
    }
}
