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

<?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

<?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

<?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

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

　　

结果

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"
}
