鸿蒙中用HarmonyOS SDK应用服务 HarmonyOS5开发一个医院查看报告小程序

一、开发环境准备

工具安装：
- 下载安装DevEco Studio 4.0+（支持HarmonyOS 5）
- 配置HarmonyOS SDK 5.0+
- 确保Node.js版本≥14
项目初始化：
```
ohpm init @harmony/hospital-report-app
```

二、核心功能模块实现

1. 报告列表展示

// ReportList.ets
@Component
struct ReportList {@State reports: Array<ReportItem> = []@State isLoading: boolean = trueaboutToAppear() {this.fetchReports()}async fetchReports() {try {const result = await ReportService.getReportList()this.reports = result.data} catch (error) {logger.error('获取报告列表失败', error)} finally {this.isLoading = false}}build() {Column() {if (this.isLoading) {LoadingProgress()} else {List({ space: 12 }) {ForEach(this.reports, (item) => {ListItem() {ReportCard({ report: item }).onClick(() => {router.pushUrl({url: 'pages/ReportDetail',params: { reportId: item.id }})})}})}}}}
}

2. 报告详情查看

// ReportDetail.ets
@Component
struct ReportDetail {@State report: MedicalReport = null@State isImageLoading: boolean = falseaboutToAppear() {const params = router.getParams()this.loadReportDetail(params['reportId'])}async loadReportDetail(reportId: string) {this.isImageLoading = truetry {this.report = await ReportService.getReportDetail(reportId)} finally {this.isImageLoading = false}}build() {Column() {// 报告基本信息ReportHeader({ report: this.report })// PDF报告查看if (this.report?.fileType === 'pdf') {PDFViewer({ src: this.report.fileUrl,controller: this.pdfController})}// 图片报告查看else if (this.report?.fileType === 'image') {Stack() {Image(this.report.fileUrl).width('100%').objectFit(ImageFit.Contain)if (this.isImageLoading) {LoadingProgress()}}}// 分享按钮Button('分享报告', { type: ButtonType.Capsule }).onClick(() => this.shareReport())}}
}

三、HarmonyOS 5特色功能集成

1. 分布式报告共享

// 跨设备分享报告
async function shareToOtherDevice(report: MedicalReport) {try {const devices = deviceManager.getAvailableDeviceListSync([DeviceType.SMART_PHONE])const result = await featureAbility.startAbilityForResult({deviceId: devices[0].deviceId,bundleName: 'com.example.medical',abilityName: 'ReportReceiverAbility',parameters: {reportData: JSON.stringify(report),action: 'shareReport'}})logger.info('分享结果:', result)} catch (error) {logger.error('跨设备分享失败', error)}
}

2. 原子化服务入口

// module.json5配置
{"abilities": [{"name": "QuickViewAbility","srcEntry": "./ets/quickview/QuickView.ets","label": "快速查看","icon": "$media:icon","startWindowIcon": "$media:icon","exported": true,"skills": [{"actions": ["action.system.view","action.medical.report.view"],"uris": [{"scheme": "medicalreport","host": "quickview"}]}]}]
}

3. 卡片服务实现

// ReportCard.ets
@Component
export struct ReportCard {@Prop report: ReportItem@State isFavorite: boolean = falsebuild() {Column() {Row() {Image(this.report.typeIcon).width(24).height(24)Text(this.report.name).fontSize(16).fontWeight(FontWeight.Medium)Blank()Image($r('app.media.favorite')).visibility(this.isFavorite ? Visibility.Visible : Visibility.None)}Divider()Row() {Text('检查日期:').fontColor('#666')Text(this.report.date).margin({ left: 8 })}// 更多报告信息...}.onClick(() => {postCardAction(this, {action: 'router',abilityName: 'ReportDetailAbility',params: { reportId: this.report.id }})})}
}

四、数据安全与管理

1. 加密存储敏感数据

// 使用HarmonyOS加密API
import cryptoFramework from '@ohos.security.cryptoFramework';async function encryptReportData(data: string): Promise<string> {try {const cipher = cryptoFramework.createCipher('RSA1024|PKCS1');await cipher.init(cryptoFramework.CryptoMode.ENCRYPT_MODE, publicKey);const input: cryptoFramework.DataBlob = { data: stringToUint8Array(data) };const output = await cipher.doFinal(input);return uint8ArrayToString(output.data);} catch (error) {logger.error('加密失败:', error);throw error;}
}

2. 数据库操作

// 使用关系型数据库存储报告缓存
const STORE_CONFIG = {name: 'medical_reports.db',securityLevel: relationalStore.SecurityLevel.S4, // 最高安全级别encryptKey: new Uint8Array(32) // 32字节加密密钥
};relationalStore.getRdbStore(context, STORE_CONFIG, (err, store) => {if (err) {logger.error('数据库初始化失败:', err);return;}// 创建报告表store.executeSql(`CREATE TABLE IF NOT EXISTS reports (id TEXT PRIMARY KEY,patient_id TEXT,report_data TEXT,created_time INTEGER)`);
});

五、UI/UX设计实现

1. 医疗风格主题

// resources/base/theme/medical_theme.json
{"color": {"medical_primary": "#1a73e8","medical_secondary": "#34a853","medical_warning": "#fbbc05","medical_danger": "#ea4335"},"font": {"medical_title": {"size": 20,"weight": 500},"medical_body": {"size": 14,"weight": 400}}
}

2. 报告分类导航

// ReportCategory.ets
@Component
struct ReportCategory {@State categories: Array<Category> = [{ id: 'lab', name: '检验报告', icon: 'lab' },{ id: 'image', name: '影像报告', icon: 'radiology' },{ id: 'pathology', name: '病理报告', icon: 'microscope' }]build() {GridRow({ columns: 4, gutter: 8 }) {ForEach(this.categories, (category) => {GridCol({ span: 1 }) {Column() {Image($r(`app.media.${category.icon}`)).width(48).height(48)Text(category.name).margin({ top: 8 })}.onClick(() => this.filterByCategory(category.id))}})}}
}

六、测试与发布

1. 单元测试示例

// ReportService.test.ets
describe('ReportService Test', () => {beforeAll(() => {// 初始化测试环境});it('should fetch report list successfully', async () => {const mockData = [{ id: '1', name: '血常规' }];jest.spyOn(http, 'request').mockResolvedValue({ data: mockData });const result = await ReportService.getReportList();expect(result).toEqual(mockData);});it('should handle network error', async () => {jest.spyOn(http, 'request').mockRejectedValue(new Error('Network Error'));await expect(ReportService.getReportList()).rejects.toThrow('获取报告列表失败');});
});

2. 应用发布准备

签名配置：

hdc appmode install --signature [签名文件] --bundle-name [包名]

上架华为应用市场：
- 准备医疗类应用特殊资质文件
- 确保符合《移动医疗应用数据安全规范》
- 提交隐私合规审查

七、性能优化建议

报告图片懒加载：

// LazyImage.ets
@Component
struct LazyImage {@Prop src: string@State isLoaded: boolean = falsebuild() {Stack() {if (this.isLoaded) {Image(this.src).onComplete(() => this.isLoaded = true)} else {Placeholder()}}}
}

数据预加载：

// 在用户登录后预加载常用报告
UserService.onLogin(() => {ReportService.prefetchReports();
});

缓存策略：

// 使用两级缓存
const CACHE_STRATEGY = {memoryCache: new Map<string, any>(),diskCache: new PreferencesCache(),async get(key: string) {if (this.memoryCache.has(key)) {return this.memoryCache.get(key);}const diskData = await this.diskCache.get(key);if (diskData) this.memoryCache.set(key, diskData);return diskData;}
};

通过以上实现，您可以构建一个符合HarmonyOS 5设计规范、功能完善的医院报告查看小程序，充分利用鸿蒙的分布式能力和安全特性，为患者提供安全便捷的报告查询体验。
