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：
|
1
2
3
4
5
6
7
8
9
10
11
12
|
/** * The event listener mappings for the application. * * @var array */protected $listen = [ ...... 'App\Events\Statistics' => [ 'App\Listeners\BehavioralStatistics', ], ......]; |
2、执行
|
1
|
php artisan event:generate |
生成事件类与监听类
3、定义事件

<?phpnamespace 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：

<?phpnamespace 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：
|
1
|
event(new Statistics(user, user,user,production)); |
以上这篇laravel 使用事件系统统计浏览量的实现就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持服务器之家。
