laravel 使用事件系统统计浏览量

我的个人博客：逐步前行STEP

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

appProvidersEventServiceProvider

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($user,$production));
