HarmonyOS 如何获取主机名、主机ip、mac地址等信息

1、设备名：

static test(context: Context) {
  settings.getValue(context, settings.general.DEVICE_NAME).then((value) => {
    console.log(`...test value -> ${JSON.stringify(value)}`)
  }).catch((err: BusinessError) => {
    console.error(`...test error code: ${err.code}, message: ${err.message}`);
  });
}

2、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));
    })
  }
}

3、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");
});
