最近有一个商城项目中有统计商品点击量和艺术家访问量的需求，但又不想改动太多原来的代码，而点击与访问这两个动作是有明确触发点的，正好可以用laravel中的事件系统来做，在点击和访问对应的函数中产生这俩事件，监视器获取到之后，再将记录保存到数据库中，并更新计数。
1、在 app\Providers\EventServiceProvider
中注册监听器：
/** * The event listener mappings for the application. * * @var array */ protected $listen = [ ...... 'App\Events\Statistics' => [ 'App\Listeners\BehavioralStatistics', ], ...... ];
2、执行
php artisan event:generate
生成事件类与监听类
3、定义事件
<?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 Statistics
{
use Dispatchable, InteractsWithSockets, SerializesModels;
public $user;
public $obj;
/**
* Create a new event instance.
*
* @return void
*/
public function __construct($user,$obj)
{
$this->user = $user;
$this->obj = $obj;
}
/**
* Get the channels the event should broadcast on.
*
* @return \Illuminate\Broadcasting\Channel|array
*/
public function broadcastOn()
{
return new PrivateChannel('channel-name');
}
}
4、定义监听器：
<?php
namespace App\Listeners;
use App\Events\Statistics;
use App\System\StaticsView;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Support\Facades\Log;
class BehavioralStatistics
{
/**
* Create the event listener.
*
* @return void
*/
public function __construct()
{
//
}
/**
* Handle the event.
*
* @param Statistics $event
* @return void
*/
public function handle(Statistics $event)
{
$obj_class = get_class($event->obj);
$statics_view = new StaticsView;
switch($obj_class){
case "App\\User":
$statics_view->statics_type = 'user';
break;
case "App\\Production":
$statics_view->statics_type = 'production';
break;
}
$statics_view->ip = request()->getClientIp();;
$statics_view->time_local = 0;
$statics_view->statics_id = $event->obj->id;
$statics_view->save();
}
}
5、触发事件：
event(new Statistics(user, user,user,production));
