HarmonyOS NEXT实战：获取设备信息

Question

[##HarmonyOS Next实战##HarmonyOS SDK应用服务##教育##]

核心概念：

@ohos.deviceInfo (设备信息)
该模块提供终端设备信息查询，开发者不可配置。
注意：该模块接口返回设备常量信息，建议应用只调用一次，不需要频繁调用。

导入模块：

import { deviceInfo } from '@kit.BasicServicesKit';

实战代码

import { deviceInfo } from '@kit.BasicServicesKit';

@Entry
@Component
struct DeviceInfoPage {
  @State deviceType: ResourceStr = '';
  @State manufacture: ResourceStr = '';
  @State brand: ResourceStr = '';
  @State marketName: ResourceStr = '';
  @State productSeries: ResourceStr = '';
  @State productModel: ResourceStr = '';
  @State productModelAlias: ResourceStr = '';
  @State odid: ResourceStr = '';
  @State sdkApiVersion: number = 0;

  build() {
    Column({ space: 6 }) {
      Text('DeviceInfoPage')

        .fontWeight(FontWeight.Bold)
