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));
