今天长沙网络推广就为大家分享一篇laravel 使用事件系统统计浏览量的实现,具有很好的参考价值,希望对大家有所帮助。一起跟随长沙网络推广过来看看吧

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));
