以下是我对事件使用的一些记录
执行以下命令，执行完成后，会在 app\Events 下面出现一个 DeleteEvent.php 文件，事件就在次定义
php artisan make:event DeleteEvent
#DeleteEvent.php<?php
namespace App\Events;
use App\Events\Event;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
class DeleteEvent extends Event
{
use SerializesModels;
public function __construct()
{
//
}
public function broadcastOn()
{
print ‘delete event‘;
}
}
执行以下命令，执行完成后，会在 app\Listeners 下面出现一个 DeleteEventListener.php 文件，是对事件 DeleteEvent的监听
php artisan make:listener --event=DeleteEvent DeleteEventListener
#DeleteEventListener.php<?php
namespace App\Listeners;
use App\Events\DeleteEvent;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
class DeleteEventListener
{
public function __construct()
{
//
}
public function handle(DeleteEvent $event)
{
//
$event->broadcastOn();
}
}
#EventController.php<?php
namespace App\Http\Controllers;
use App\Events\DeleteEvent;
use App\Events\SomeEvent;
use Illuminate\Http\Request;
use App\Http\Requests;
class EventController extends Controller
{
//
public function index()
{
// event(new SomeEvent()); //框架默认调用broadcastOn()
$event = new DeleteEvent(); //自定义
event($event->broadcastOn());
}
}
#routes.phpRoute::get(‘/event‘,[‘uses‘=>‘EventController@index‘]);
