HarmonyOS 如何获取ip地址和mac地址

1、获取mac地址权限：ohos.permission.GET_WIFI_INFO代码：

wifiManager.getLinkedInfo().then(
  data => {
    console.info("get wifi linked info: " + JSON.stringify(data));
  }).catch((error: number) => {
  console.info("get linked info error");
});

2、获取ip地址权限：ohos.permission.GET_NETWORK_INFO代码：

let netHandle = await connection.getDefaultNet();
if (netHandle) {
  let connectionProperties = await connection.getConnectionProperties(netHandle)
  if (connectionProperties && connectionProperties.linkAddresses) {
    connectionProperties.linkAddresses.forEach((address: connection.LinkAddress, index: number) => {
      console.info("get address info: " + JSON.stringify(address));
    })
  }
}
