GatewayClient如何可以判断GatewayWorker是否启动

    // $this->ws  127.0.0.1:1239
    public function isWsStart()
    {
        try {
            $client = stream_socket_client('tcp://' . $this->ws, $errno, $errmsg, 3);
        } catch (\Exception $e) {
            return false;
        }
        return true;
    }

    public function isOnline($uid)
    {
        Gateway::$registerAddress = $this->ws;
        return Gateway::isUidOnline($uid); //在线返回1 不在线返回0
    }
