lumen 事件

今天需要实现日志功能，所有使用了一下lumen的event（事件）和listener（监听）

Lumen事件：https://lumen.laravel-china.org/docs/5.3/events   http://laravelacademy.org/post/3441.html

Laravel 的事件系统：https://d.laravel-china.org/docs/5.5/events

Laravel 5 事件的使用：https://www.cnblogs.com/chenqionghe/p/4884390.html

 

看完上面的文章基本就能实现了，下面做一些记录

我需要实现开门的日志写入

首先是OpenDoorEvent.php

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

<?php   namespace App\Events;   class OpenDoorEvent extends Event {     /**      * Create a new event instance.      *      * @return void      */     public $data;       public function __construct($data)     {         $data['ip'] = $_SERVER["REMOTE_ADDR"];         $data['open_time'] = date('Y-m-d H:i:s', time());         $this->data = $data;     }       public function getData()     {         return $this->data;     }   }

　　

然后实现OpenDoorListener.php

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44

<?php   namespace App\Listeners;   use App\Events\OpenDoorEvent; use Illuminate\Queue\InteractsWithQueue; use Illuminate\Contracts\Queue\ShouldQueue;   class OpenDoorListener {       public $data;       /**      * Create the event listener.      *      * @return void      */     public function __construct()     {         //     }       /**      * Handle the event.      *      * @param  ExampleEvent $event      * @return void      */     public function handle(OpenDoorEvent $event)     {         $data = $event->getData();         $this->data = $data;         $this->run();     }       public function run()     {         if (!$this->data) return;         var_dump($this->data);         /** ... */     }   }

　　

　　

接下来是注册监听EventServiceProvider.php

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

<?php   namespace App\Providers;   use App\Events\OpenDoorEvent; use App\Listeners\OpenDoorListener; use Laravel\Lumen\Providers\EventServiceProvider as ServiceProvider;   class EventServiceProvider extends ServiceProvider {     /**      * The event listener mappings for the application.      *      * @var array      */     protected $listen = [         'App\Events\SomeEvent' => [             'App\Listeners\EventListener',         ],         /*         'App\Events\OpenDoorEvent' => [             'App\Listeners\OpenDoorListener',         ],         */         OpenDoorEvent::class => [             OpenDoorListener::class         ],     ]; }

　　

最后随便找个控制器调用一下，在run方法把$data输出

?

1 2 3 4 5 6 7

$data = [             'user_id' => 1,             'room_id' => 1,             'key' => '123456',             'status' => 1 ]; event(new OpenDoorEvent($data));exit();

　　

结果

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

array(6) {   ["user_id"]=>   int(1)   ["room_id"]=>   int(1)   ["key"]=>   string(6) "123456"   ["status"]=>   int(1)   ["ip"]=>   string(9) "127.0.0.1"   ["open_time"]=>   string(19) "2018-01-30 15:46:24" }
