网络信息-UDPSocket连接 报错 "code":2301022,"？

Question

使用 @ohos.net.socket (Socket连接) 中代码样例，模拟Udp协议发送，参考链接：https://developer.huawei.com/consumer/cn/doc/harmonyos-references/js-apis-socket-0000001820881633\#ZH-CN\_TOPIC\_0000001811157366\_\_send

报错日志:

{"code":2301022,"message":"Invalid argument"} ,

问题场景描述：

通过Udp协议与指定服务通讯,代码如下,是哪个参数有异常? 怎么解决?

import buffer from '@ohos.buffer';
import socket from '@ohos.net.socket';
import { BusinessError } from '@ohos.base';

... ...

test() {

  let udp: socket.UDPSocket = socket.constructUDPSocketInstance();

  let bindAddr: socket.NetAddress = {
    address: '127.0.0.1',
  }

  let sendOptions: socket.UDPSendOptions = {
    data: 'Hello!',
    address: {
      address: '8.xxx.10.183',
      port: 52826
    }
  }

  udp.bind(bindAddr).then(() => {
    console.log(' bind success');

    udp.send(sendOptions).then(() => {

      console.log(' send success');

    }).catch((err: BusinessError) => {

      console.log(' send fail' + JSON.stringify(err));

    });

  }).catch((err: BusinessError) => {
    console.log(' bind fail' + JSON.stringify(err));
  });

}

bindAddr中，address设置为网卡地址，获取方式可以参考如下链接：

https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-net-connection-V5\#connectiongetconnectionproperties

address值为返回值中data.linkAddresses[0].address.address
