背景：

前几篇学习了元服务，后面几期就让我们开发简单的元服务吧，里面丰富的内容大家自己加，本期案例 仅供参考

先上本期效果图 ，里面图片自行替换

效果图1完整代码案例如下：

• Index

import { authentication } from '@kit.AccountKit';
import { BusinessError } from '@kit.BasicServicesKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { TypeShortVideoItem } from './TypeShortVideoItem';

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';

  build() {
    Column() {
      Text($r('app.string.EntryAbility_label')).fontSize(20).margin({ bottom: 10 })
      List({ space: 6 }) {
        ForEach(['《星辰大海》- 黄霄雲',
          '《青花瓷》- 周杰伦',
          '《追光者》- 岑宁儿',
          '《小幸运》- 田馥甄',
          '《野狼 disco》- 宝石 Gem',
        ], (item: string) => {
          ListItem() {
            TypeShortVideoItem({ title: item })
          }

        })


      }

    }
    .alignItems(HorizontalAlign.Start)
    .height('100%')
    .padding(8)
    .width('100%')
    .margin({ top: 40 })
  }

  aboutToAppear() {
    hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onCreate');
    this.loginWithHuaweiID();
  }

  /**

  private loginWithHuaweiID() {
    // Create a login request and set parameters
    let loginRequest = new authentication.HuaweiIDProvider().createLoginWithH
