我正在尝试编写一个代码,当它与我的计算机在同一网络上时,它将返回我的覆盆子的IP.这个想法是让它像Samba一样进行广播(广播解析是最接近原始NetBIOS机制的.基本上,寻找名为Trillian的服务的客户会喊出“哟！Trillian！你在哪里？”,等待具有该名称的机器以IP地址回答.来源：Samba团队)

        }
        public void run(){
            try {
                result = getHTML(this.url_test);  //result = the response from the GET request to this.url_test
            } catch (Exception e) {
            }
            if(result
