HarmonyOS 怎样获取蜂窝网络的ip和手机的mac地址？

使用getConnectionPropertiesSync返回结果的ConnectionProperties.linkAddresses属性获取蜂窝网络的ip，参考代码：

Text(this.message)
Button('异步获取IP地址')
  .onClick(() => {
    connection.getDefaultNet().then((netHandle: connection.NetHandle) => {
      connection.getConnectionProperties(netHandle).then((data: connection.ConnectionProperties) => {
        console.info("Succeeded to get data: " + JSON.stringify(data));
        this.message = JSON.stringify(data.linkAddresses);
      })
    });
  })

Button('同步获取IP地址')
  .onClick(() => {
    let net = connection.getDefaultNetSync()
    try {
      let properties = connection.getConnectionPropertiesSync(net)
      this.message = JSON.stringify(properties.linkAddresses)
      console.log(JSON.stringify(properties))
      console.log(JSON.stringify(properties.linkAddresses))
    } catch (err) {
      this.message = JSON.stringify(err)
    }
  })
}
