webman启动同时加入自定义进程加入phpsocketIo怎么写啊？

'socketio' => [
                'handler' => app\command\SocketIoStart::class,
                'listen' => 'http://0.0.0.0:3120',
                'count' => 1,
            ],

use PHPSocketIO\SocketIO;
class SocketIoStart 
{   public function onWorkerStart()
         //这里用用onConnect() 或者onWorkerStart都不行
    {
      $io = new SocketIO(3120);
      $io->on('connection', function($socket)use($io){
          echo "new connection coming\n";
        });

        Worker::runAll();
    }
}
另外这样把socketio加入到webman一同启动是否合理啊？
