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));
