HarmonyOS 鸿蒙Next应用内部检测到新版本如何实现升级安装

1、可以通过应用市场服务api监测更新，弹框提示更新，可以参考以下文档：‘https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/store-update-V5’

2、也可以自己监测版本，通过context.startAbility拉起鸿蒙应用市场详情页面：

import Want from '@ohos.app.ability.Want';
import common from '@ohos.app.ability.common';

@Entry
@Component
struct Index {
  @State appId: string = 'C1142586279411547392';
  controller: TextInputController = new TextInputController();
  build() {
    Row() {
      Column() {
        TextInput({ text: this.appId, placeholder: '请输入应用的appId', controller: this.controller })
          .width('90%')
          .onChange((value: string) => {
            this.appId = value
          })
        Button('点击跳转到鸿蒙版应用市场详情页面')
          .margin({top: 50})
          .onClick(()=>{
            const want: Want = {
              uri: store://appgallery.huawei.com/app/detail?id=${this.appId}
            };
            const context = getContext(this) as common.UIAbilityContext;
            context.startAbility(want).then(()=>{
              //拉起成功
            }).catch(()=>{
              // 拉起失败
            });
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}
