HarmonyOS NEXT 实战之元服务：静态案例效果（二）

theme: channing-cyan

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

效果图代码案例如下：

• Index里面实现

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, // 数字个数
  'DURATION_TIME': 200, // 动画时长
  'MILLENNIAL_LEN': 3 // 千分位长度
}

export const STYLE_CONFIG: Record<string, number> = {
  'ITEM_GUTTER': 12, // 元素间距
  'ITEM_HEIGHT': 26, // 数字元素高度
  'TEXT_MARGIN': 2, // 文本间距
  'PADDING_TOP': 32  // 顶部边距
}



@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($r('app.string.digital_scroll_animation_max_size'))
        .textAlign(TextAlign.Start)
        .margin({left:25})
      Row({ space: 10 }) {
        Text(this.getDate())
          .fontSize($r('app.string.ohos_id_text_size_headline'))
          .fontWeight(FontWeight.Medium)
          .height(30)
          .fontColor(Color.White)
        Text('天气  多云 18℃')
          .height(30)
      }
      .width('100%').margin({left:15})


      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 parameters
    let loginRequest = new authentication.HuaweiIDProvider().createLoginWithHuaweiIDRequest();
    // Whether to forcibly launch the HUAWEI ID login page when the user is not logged in with the HUAWEI ID
    loginRequest.forceLogin = false;
    // Execute login request
    let 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

      }
    });
  }

  private getDate() {
    const now = new Date();
    const year = now.getFullYear();
    const month = now.getMonth() + 1; // 注意：月份是从0开始计数的
    const day = now.getDate();
    const hours = now.getHours();
    const minutes = now.getMinutes();
    const seconds = now.getSeconds();
    return `${year} 年 ${month} 月 ${day} 日`
  }
}

• AddressExchangeViewComponent 里面实现

import { promptAction } from "@kit.ArkUI"

@Preview
@Component
export struct AddressExchangeViewComponent {

  build() {

    Column({ space: 16 }) {

      Row() {
        Text('附近汽车租赁门店')
          .fontSize(18)
          .fontColor(Color.Black)

        Text('查看更多>')
          .fontSize(15)
          .fontColor(Color.Black)
      }.justifyContent(FlexAlign.SpaceBetween).width('100%').padding(10).onClick(() => {
      })

      Row({ space: 20 }) {
        Column({ space: 10 }) {
          Text() {
            Span('小王汽车租赁门店')
          }.fontWeight(FontWeight.Bold).fontSize(13)

          Row({space:4}) {
            Image($r('app.media.weizhi')).width(18).height(18)

          }

        }

          Row({space:4}) {
