Lavel-Event（laravel-事件系统）

先使用命令行生成一个事件文件

    php artisan make:event TestEvent

文件内容如下：

<?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 TestEvent
{
    use Dispatchable, InteractsWithSockets, SerializesModels;
    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct($data = [])
    {
        $this->data = $data;
    }
    /**
     * Get the channels the event should broadcast on.
     *
     * @return \Illuminate\Broadcasting\Channel|array
     */
    public function broadcastOn()
    {
        return new PrivateChannel('channel-name');
    }
}

然后在App/Providers/EventServiceProvider 下定义事件和监听器

    protected $listen = [
        'App\Events\TestEvent' => [
            'App\Listeners\TestListener',
        ],
    ];

执行php artisan event:generate 生成监听器

<?php
namespace App\Listeners;
use App\Events\TestEvent;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
class TestListener
{
    /**
     * Create the event listener.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }
    /**
     * Handle the event.
     *
     * @param  TestEvent  $event
     * @return void
     */
    public function handle(TestEvent $event)
    {
        //
    }
}

控制器中写入

    event(new TestEvent());
