一、开发准备
-
环境搭建:
- 安装DevEco Studio 3.0或更高版本
- 配置HarmonyOS SDK
- 申请开发者账号
-
项目创建:
File > New > Create Project > Application (选择"Empty Ability")
二、核心功能实现
1. 医院科室展示
// 科室列表组件
@Component
struct DepartmentList {@State departments: Array<Department> = [{id: 1, name: '内科', icon: 'department1'},{id: 2, name: '外科', icon: 'department2'},// 更多科室...]build() {List({ space: 10 }) {ForEach(this.departments, (item: Department) => {ListItem() {DepartmentItem({ department: item })}})}}
}
2. 医生排班查询
// 医生排班API调用
async function fetchDoctorSchedule(departmentId: number) {try {let response = await http.request({url: 'https://api.example.com/schedule',method: 'GET',data: { departmentId }});return response.data;} catch (error) {console.error('获取排班失败:', error);}
}
3. 预约挂号功能
// 预约提交逻辑
function submitAppointment(appointment: Appointment) {// 验证表单if (!validateAppointment(appointment)) {prompt.showToast({ message: '请填写完整信息' });return;}// 调用预约APIhttp.request({url: 'https://api.example.com/appointments',method: 'POST',data: appointment,success: (res) => {prompt.showToast({ message: '预约成功' });router.replace({ uri: 'pages/appointmentDetail' });},fail: (err) => {prompt.showToast({ message: '预约失败,请重试' });}});
}
三、关键HarmonyOS特性应用
-
分布式能力:
// 跨设备预约提醒 function distributeReminder(appointment: Appointment) {let devices = deviceManager.getTrustedDeviceListSync();devices.forEach(device => {featureAbility.startAbility({deviceId: device.deviceId,bundleName: 'com.example.hospital',abilityName: 'ReminderAbility',message: JSON.stringify(appointment)});}); } -
卡片服务:
// config.json中的卡片配置 {"forms": [{"name": "AppointmentCard","description": "预约信息卡片","type": "JS","jsComponentName": "AppointmentCard","colorMode": "auto","isDefault": true,"updateEnabled": true,"scheduledUpdateTime": "10:30","updateDuration": 1,"defaultDimension": "2 * 2","supportDimensions": ["2 * 2", "2 * 4"]}] } -
原子化服务:
// 快速预约入口 @Entry @Component struct QuickAppointment {build() {Column() {Button('快速挂号', { type: ButtonType.Capsule }).onClick(() => {router.push({ uri: 'pages/quickAppointment' });})}} }
四、数据管理
-
本地存储:
// 存储用户信息 preferences.putPreferences({name: 'userPrefs',data: {userId: '12345',name: '张三',medicalCard: '0987654321'} }, (err) => {if (err) {console.error('存储失败:', err);} }); -
数据库操作:
// 创建本地数据库 const STORE_CONFIG = {name: 'hospital.db',encryptKey: new Uint8Array([]),securityLevel: relationalStore.SecurityLevel.S1 };relationalStore.getRdbStore(this.context, STORE_CONFIG, (err, store) => {if (err) {console.error('数据库初始化失败:', err);return;}// 执行SQL操作 });
五、UI设计建议
-
医疗风格配色:
// 全局样式 @Styles function medicalStyle() {.backgroundColor('#f0f9ff').fontColor('#0369a1') } -
无障碍设计:
Text('预约时间').accessibilityText('预约时间,请选择您方便的就诊时间').accessibilityImportance('high')
六、发布与运维
-
应用签名:
keytool -genkeypair -alias "hospitalKey" -keyalg RSA -keysize 2048 ... -
应用上架:
- 准备应用图标和截图
- 填写应用描述和分类
- 提交华为应用市场审核
七、注意事项
-
医疗合规性:
- 确保符合医疗数据保护法规
- 实现患者隐私保护措施
- 医疗API需要HTTPS加密
-
性能优化:
- 预约高峰期时的服务器负载考虑
- 本地缓存常用数据减少网络请求
-
异常处理:
// 网络异常处理 try {await fetchData(); } catch (error) {if (error.code === 1001) {prompt.showToast({ message: '网络连接超时' });} else {prompt.showToast({ message: '服务暂时不可用' });} }
