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));
    })
  }
}
