基于mPaaS+HarmonyOS 5的原子化服务快速上架指南

以下为 ​​mPaaS+HarmonyOS 5原子化服务快速上架指南​​，包含从开发到发布的完整代码示例与流程：

---

1. 创建原子化服务工程

1.1 使用DevEco Studio模板

# 创建原子化服务工程
ohpm create @harmonyos/atomic-service my-mpaas-service --template mpaas-integration

1.2 工程结构

my-mpaas-service/
├── entry/
│   ├── src/main/ets/
│   │   ├── pages/
│   │   ├── services/
│   │   └── app.ets
├── mpaas-config.json
└── atomic-service.json

---

2. 集成mPaaS SDK

2.1 配置依赖

// oh-package.json5
{
  "dependencies": {
    "@mpaas/core": "^3.5.0",
    "@mpaas/api-gateway": "^2.1.0",
    "@harmonyos/atomic-service": "^5.0.0"
  }
}

2.2 初始化mPaaS

// app.ets
import mPaaS from '@mpaas/core';

@Entry
@Component
struct App {
  aboutToAppear() {
    mPaaS.init({
      appKey: 'YOUR_APP_KEY',
      gateway: 'https://api.example.com'
    });
  }

  build() {
    Column() {
      Router()
    }
  }
}

---

3. 开发原子化服务

3.1 定义服务能力

// services/payment-service.ets
@Component
export struct PaymentService {
  @Ability
  static async quickPay(amount: number, orderId: string): Promise<PaymentResult> {
    return mPaaS.invoke('payment.create', { amount, orderId });
  }

  @Ability
  static getPaymentHistory(userId: string): PaymentHistory[] {
    return mPaaS.query('payment.history', { userId });
  }
}

3.2 配置原子化能力

// atomic-service.json
{
  "abilities": [
    {
      "name": "quickPay",
      "description": "快速支付服务",
      "parameters": [
        { "name": "amount", "type": "number" },
        { "name": "orderId", "type": "string" }
      ],
      "returnType": "PaymentResult"
    }
  ],
  "permissions": ["mpaas.payment"]
}

---

4. 极简UI开发

4.1 支付卡片组件

// components/pay-card.ets
@Component
struct PayCard {
  @Link amount: number

  build() {
    Button(`支付 ¥${this.amount}`)
      .width('90%')
      .height(60)
      .onClick(() => PaymentService.quickPay(this.amount, generateOrderId()))
  }
}

4.2 服务入口页面

// pages/index.ets
@Entry
@Component
struct PaymentPage {
  @State amount: number = 100

  build() {
    Column() {
      PayCard({ amount: $amount })
      Slider({ value: this.amount, min: 1, max: 1000 })
        .onChange(v => this.amount = v)
    }
  }
}

---

5. 服务发布配置

5.1 上架清单配置

// app.json
{
  "appName": "mPaaS支付服务",
  "version": "1.0.0",
  "minAPIVersion": 5,
  "targetAPIVersion": 5,
  "serviceType": "atomic",
  "distribution": {
    "categories": ["finance"],
    "countries": ["CN"]
  }
}

5.2 构建发布包

# 构建原子化服务HAP
ohpm build --mode release --target atomic-service

# 生成上架包
ohpm pack --output dist/mpaas-payment.hap

---

6. 服务测试验证

6.1 本地单元测试

// tests/payment.test.ets
describe('支付服务测试', () => {
  it('应成功创建支付订单', async () => {
    const result = await PaymentService.quickPay(100, 'test123');
    expect(result.success).toBeTruthy();
    expect(result.orderId).toMatch(/^\w{10}$/);
  });
});

6.2 真机调试命令

# 安装到测试设备
ohpm install dist/mpaas-payment.hap --device 192.168.1.100

# 启动服务调试
ohpm debug --port 8080

---

7. 应用市场发布

7.1 上传到AppGallery Connect

# 使用华为发布工具
hag-tool upload \
  --file dist/mpaas-payment.hap \
  --app-id YOUR_APP_ID \
  --release-notes "初始版本发布"

7.2 配置服务分发

# publish-config.yml
release:
  phases:
    - name: 灰度发布
      percentage: 10%
      countries: [CN]
    - name: 全量发布
      after: 72h
audience:
  devices: [car, phone, tablet]
  minOS: HarmonyOS 5.0

---

8. 关键代码片段说明

8.1 服务路由配置

// routes.ets
const routes: Route[] = [
  {
    path: '/payment',
    component: PaymentPage,
    abilities: [PaymentService]
  },
  {
    path: '/history',
    component: HistoryPage,
    abilities: [PaymentService.getPaymentHistory]
  }
];

8.2 服务安全策略

// security.ets
class PaymentSecurity {
  @SecureMethod
  static async verifyPayment(params: any): Promise<boolean> {
    return mPaaS.invoke('security.verify', {
      ...params,
      deviceId: DeviceInfo.getId()
    });
  }
}

---

9. 性能优化建议

优化方向	实现方法	代码示例
资源懒加载	按需加载mPaaS模块	import('@mpaas/payment')
数据预取	启动时预加载用户数据	mPaaS.prefetch('user')
服务缓存	高频查询结果缓存	Cache.set(key, data)
代码分包	非核心能力动态加载	ohpm split-chunks

---

10. 完整上架流程

   # 集成mPaaS
   ohpm install @mpaas/core @mpaas/api-gateway
   

2. ​​测试阶段​​

   # 运行单元测试

   // 添加监控埋点
   mPaaS.monitor('service_start', { 
     service: 'payment' 
   });
