本文介绍了一个基于事件的系统设计案例，包括事件触发、事件定义、事件监听绑定及事件处理逻辑实现等步骤。通过Controller触发OrderApproved事件，在EventServiceProvider中绑定监听器，并在监听器中更新库存状态。

1，controller中调用
event(new OrderApproved($reportTaskModel));
2，app/Event/

OrderApproved.php中继承event

class OrderApproved extends Event
{
    use SerializesModels;
    /**
     * @var InventoryHistoryDetailsReportTask
     */
    public $reportTask;

    /**
     * Create a new event instance.
     *
     * @param ReportTask $reportTask
     */
    public function __construct(ReportTask $reportTask)
    {
        //
        $this->reportTask = $reportTask;
    }

    /**
     * Get the channels the event should be broadcast on.
     *
     * @return array
     */
    public function broadcastOn()
    {
        return [];
    }
}

3，app/Providers/EventServiceProvider.php中绑定

protected $listen = [
    'SocialiteProviders\Manager\SocialiteWasCalled' => [
        // add your listeners (aka providers) here
        'SocialiteProviders\Thebizark\ThebizarkExtendSocialite@handle',
        'SocialiteProviders\Qq\QqExtendSocialite@handle',
        'SocialiteProviders\Weibo\WeiboExtendSocialite@handle',
        'SocialiteProviders\Weixin\WeixinExtendSocialite@handle',
        'SocialiteProviders\Live\LiveExtendSocialite@handle',
    ],
    \App\Events\OrderApproved::class => [
        \App\Listeners\OrderApprovedEventListenerNotification::class,
    ],]
4,

OrderApprovedEventListenerNotification.php中处理物理逻辑（

updateInventoryStatus

）

class

OrderApprovedEventListenerNotification

{ /** * @var DetailsReportServiceTask */ private $detailsReportServiceTask; /** * Create the event listener. * * @param DetailsReportServiceTask $detailsReportServiceTask */ public function __construct(DetailsReportServiceTask $detailsReportServiceTask) { // $this->detailsReportServiceTask = $detailsReportServiceTask; } /** * Handle the event. * * @param DetailsReportTaskApproved $event * @return void */ public function handle(DetailsReportTaskApproved $event) { // try{ $this->detailsReportServiceTask->updateInventoryStatus($event->detailsReportTask,[ 'task_status'=>DetailsReportTaskRepository::TASKSTATUS_QUEUED, ]); }catch(AppRuntimeException $ex){// Log::error('Event updateInventoryStatus Exception',['code'=>$ex->getCode(),'message'=>$ex->getMessage()]); } }}
