                        //绑定操作类回调函数
                        $app = App::make('App\Handles\SwooleWebSocketHandle');
    
                        $this->server->on('open',array($app,'onOpen'));
    
                        $this->server->on('message',array($app,'onMessage'));
    
                        $this->server->on('close',array($app,'onClose'));
    
                        $this->info("\r\nprocess created successful!\r\n");
    
                        $this->server->start();
                        break;
    
                    case 'stop':
                        if(!$pid = $this->getPid())
                        {
                            $this->error("\r\nprocess not started!\r\n");
                            exit;
                        }
                        if(\Swoole\Process::kill((int)$pid))
                        {
                            $this->info("\r\nprocess close successful!\r\n");
                            exit;
                        }
                        $this->info("\r\nprocess close failed!\r\n");
                        break;
    
                    default:
                        $this->error("\r\noperation method does not exist!\r\n");
                }
    
            }
    
            //获取pid
            private function getPid()
            {
                return file_exists($this->pid_file) ? file_get_contents($this->pid_file) :false;
            }
        }

以上命令定义完成可使用artisan来管理swoole websocket服务的开启和关闭

php artisan swoole start  //开启
    php artisan swoole stop //关闭

**2.使用Handles类来处理swoole的事件处理**

//在SwooleManger中使用了 
    $app = App::make('App\Handles\SwooleWebSocketHandle'); //将SwooleWebsocketHandle注入到SwooleManger中

使用$this->server->on 注册事件回调函数，创建App\\Handles\\SwooleWebSocketHandle文件实现webSocket的事件即可
