最近有一個商城項目中有統(tǒng)計商品點擊量和藝術(shù)家訪問量的需求，但又不想改動太多原來的代碼，而點擊與訪問這兩個動作是有明確觸發(fā)點的，正好可以用laravel中的事件系統(tǒng)來做，在點擊和訪問對應(yīng)的函數(shù)中產(chǎn)生這倆事件，監(jiān)視器獲取到之后，再將記錄保存到數(shù)據(jù)庫中，并更新計數(shù)。
1、在 app\Providers\EventServiceProvider
中注冊監(jiān)聽器：
/**
* The event listener mappings for the application.
*
* @var array
*/
protected $listen = [
......
'App\Events\Statistics' => [
'App\Listeners\BehavioralStatistics',
],
......
];
2、執(zhí)行
php artisan event:generate
生成事件類與監(jiān)聽類
3、定義事件
?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、定義監(jiān)聽器：
?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、觸發(fā)事件：
event(new Statistics(user, user,user,production));
