import { BusinessError } from '@ohos.base';

@Entry
@Component
struct VersionExample {
  @State version: string = '';

  aboutToAppear() {
    this.getAppVersion();

  // 获取应用版本号
  async getAppVersion() {
    try {
      const bundleInfo = await bundleManager.getBundleInfoForSelf(0);
      console.log('----版本号', bundleInfo.versionName)
      this.version = bundleInfo.versionName; // 获取版本名称
    } catch (error) {
      console.error('获取版本号失败:', (error as BusinessError).message);
    }
