HarmonyOS鸿蒙Next中怎么样打开华为应用市场‘更新app’详情页

可以基于context.startAbility方法拉起指定应用，并携带参数。其中type是固定配置值，uri是"store://appgallery.huawei.com/app/detail"拼接上id参数，才能拉起鸿蒙应用市场详情页面。

uri: 'store://appgallery.huawei.com/app/detail?id='+appId

具体代码demo:

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

@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%')
  }
}
