laravel自定义事件(event)

添加event监听者

在\app\Providers目录下EventServiceProvider.php文件，添加事件和监听者的映射。

<?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',
        ],
        
        // 新增事件
        'App\Events\AsyncNotifyEvent' => [
            'App\Listeners\AsyncEmailNotifyEventListener',// 发送邮件通知
            'App\Listeners\AsyncMassageNotifyEventListener',// 发送短信通知
        ],
    ];

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

        //
    }
}

生成监听者类

$ php artisan event:generate
Events and listeners generated successfully!

生成两个文件AsyncEmailNotifyEventListener.php 和 AsyncMassageNotifyEventListener.php

$ tree 
.
├── AsyncEmailNotifyEventListener.php
├── AsyncMassageNotifyEventListener.php
└── EventListener.php

添加处理逻辑

我们这里添加记录日志方式测试

AsyncEmailNotifyEventListener

<?php

namespace App\Listeners;

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

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

    /**
     * Handle the event.
     *
     * @param  AsyncNotifyEvent  $event
     * @return void
     */
    public function handle(AsyncNotifyEvent $event)
    {
        \Log::info("Async_Email_Notify_Event_Listener OK!");
    }
}

AsyncMassageNotifyEventListener

<?php

namespace App\Listeners;

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

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

    /**
     * Handle the event.
     *
     * @param  AsyncNotifyEvent  $event
     * @return void
     */
    public function handle(AsyncNotifyEvent $event)
    {
        \Log::info("Async_Massage_Notify_Event_Listener OK!");
    }
}

测试

我们这里采用路由测试

<?php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    return view('welcome');
});

// 测试事件执行
Route::get('/event_test', function () {
    \Event::fire(new \App\Events\AsyncNotifyEvent());
    return 'success~';
});

访问路由

$ curl http://localhost:8084/event_test
success~

查看日志

$ cat ./storage/logs/laravel.log 
[2019-03-13 08:35:01] local.INFO: Async_Email_Notify_Event_Listener OK!  
[2019-03-13 08:35:01] local.INFO: Async_Massage_Notify_Event_Listener OK!
