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

在这里插入图片描述

效果图1完整代码案例如下：

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

@Entry
@Component
struct Index {
  build() {
    Column({ space: 16 }) {
      Text($r('app.string.EntryAbility_label')).fontSize(24).fontWeight(FontWeight.Bold).margin({ top: 10, left: 16 })
      Column({ space: 10 }) {

        Row() {
          this.fuYong($r('app.media.img'), '西格拉姆', '艺术博物馆')
          Column({ space: 6 }) {
            Column({ space: 7 }) {
