怎么在其他web项目向BusinessWorker客户端发送指令，并获取结果

$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
Gateway::$registerAddress = 'xxx:xx';
Gateway::sendToUid(设备id, '命令数据');
$redis->subscribe(设备id, function($instance, $channelName, $message) {
  var_export($message);
  die;
};

class Events
{
    public static function onWorkerStart()
    {
        global $redis;
        $redis = new Redis();
        $redis->connect('127.0.0.1', 6379);
    }

    public static function onMessage()
    {
        // 收到设备返回的消息
        $redis->publish(设备id, '设备返回的消息');
    }

}
