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代码

import { authentication } from '@kit.AccountKit';
import { BusinessError } from '@kit.BasicServicesKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { AddressExchangeViewComponent } from './AddressExchangeViewComponent';export const DATA_CONFIG: Record<string, number> = {'NUMBER_LEN': 7,'DURATION_TIME': 200,'MILLENNIAL_LEN': 3
}export const STYLE_CONFIG: Record<string, number> = {'ITEM_GUTTER': 12,'ITEM_HEIGHT': 26,'TEXT_MARGIN': 2,'PADDING_TOP': 32
}@Entry
@Component
struct Index {build() {Column({ space: STYLE_CONFIG.ITEM_GUTTER }) {Text($r('app.string.EntryAbility_label')).fontColor(Color.White).fontSize($r('sys.float.ohos_id_text_size_headline8')).width($r('app.string.digital_scroll_animation_max_size')).textAlign(TextAlign.Center)AddressExchangeViewComponent()}.padding({top: STYLE_CONFIG.PADDING_TOP}).margin({ top: 60 }).width($r('app.string.digital_scroll_animation_max_size')).height($r('app.string.digital_scroll_animation_max_size')).linearGradient({colors: [[$r('app.color.digital_scroll_animation_background_color'), 0.0],[$r('sys.color.ohos_id_color_background'), 0.3]]})}aboutToAppear() {hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onCreate');this.loginWithHuaweiID();}/*** Sample code for using HUAWEI ID to log in to atomic service.* According to the Atomic Service Review Guide, when a atomic service has an account system,* the option to log in with a HUAWEI ID must be provided.* The following presets the atomic service to use the HUAWEI ID silent login function.* To enable the atomic service to log in successfully using the HUAWEI ID, please refer* to the HarmonyOS HUAWEI ID Access Guide to configure the client ID and fingerprint certificate.*/private loginWithHuaweiID() {// Create a login request and set parameterslet loginRequest = new authentication.HuaweiIDProvider().createLoginWithHuaweiIDRequest();// Whether to forcibly launch the HUAWEI ID login page when the user is not logged in with the HUAWEI IDloginRequest.forceLogin = false;// Execute login requestlet controller = new authentication.AuthenticationController();controller.executeRequest(loginRequest).then((data) => {let loginWithHuaweiIDResponse = data as authentication.LoginWithHuaweiIDResponse;let authCode = loginWithHuaweiIDResponse.data?.authorizationCode;// Send authCode to the backend in exchange for unionID, session}).catch((error: BusinessError) => {hilog.error(0x0000, 'testTag', 'error: %{public}s', JSON.stringify(error));if (error.code == authentication.AuthenticationErrorCode.ACCOUNT_NOT_LOGGED_IN) {// HUAWEI ID is not logged in, it is recommended to jump to the login guide page}});}
