实现UDP发送请求功能鸿蒙示例代码

function send(ip: string, broadcast: boolean) {
  udp.setExtraOptions(
    {
      broadcast: broadcast
    }
  ).then(() => {
    udp.send({
      data: searchCMD,
      address: {
        address: ip,
        port: 10008
      }
    }).then(() => {
      storage.set("Result", "Success!\nip: " + ip + "\nbroadcast: " + broadcast);
      storage.set("Color", GREEN);
    }).catch(() => {
      storage.set("Result", "Fail!\nip: " + ip + "\nbroadcast: " + broadcast);
      storage.set("Color", RED);
    });
  });
