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：
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 }) {
Image($r('app.media.img_1')).width(150).height(100).borderRadius(10)
Text('海港大桥 ').fontSize(20).fontWeight(FontWeight.Bold)
Text('感受悉尼的繁华与活力').fontSize(15).fontColor('#B3B3B4')
}.width(200)
Column({ space: 7 }) {
Image($r('app.media.img_2')).width(150).height(100).borderRadius(10)
Text('崇礼雪场 ').fontSize(20).fontWeight(FontWeight.Bold)
Text('冬奥会滑雪项目举办地').fontSize(15).fontColor('#B3B3B4')
}.width(200)
}

}
.height('50%')
.width('90%')
.padding(16)
.borderWidth(1)
.borderRadius(12)
.borderColor('#D09538')
}
.height('100%')
.width('100%')
.backgroundColor('#F2F3F5')
.margin({ top: 60 })
}

}
}

}

private loginWithHuaweiID() {
