laravel 使用事件系统统计浏览量的实现

今天小编就为大家分享一篇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。一起跟随小编过来看看吧
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));
