HarmonyOS5 灰度发布：通过AGC控制台分阶段更新Uniapp混合应用一、鸿蒙环境适配要点 ArkUI组件适配

以下为 通过AppGallery Connect (AGC) 控制台实现Uniapp混合应用在HarmonyOS 5上灰度发布的完整技术方案，包含分阶段策略配置、设备定向推送和实时监控的代码实现：

1. 灰度发布架构

2. AGC控制台配置

2.1 创建灰度策略

// agc-gray-policy.json
{
  "appId": "YOUR_APP_ID",
  "phases": [
    {
      "name": "alpha",
      "percentage": 0,
      "deviceFilters": {
        "model": ["Mate60", "P70"],
        "osVersion": ["5.0.0+"],
        "region": ["CN"]
      }
    },
    {
      "name": "beta",
      "percentage": 5,
      "randomSeed": "2023Q3"
    },
    {
      "name": "full",
      "percentage": 100
    }
  ],
  "metrics": ["crash_rate", "api_latency"],
  "rollbackConditions": [
    {
      "metric": "crash_rate",
      "threshold": 1.0,
      "duration": "24h"
    }
  ]
}

3. Uniapp集成方案

3.1 初始化AGC SDK

// main.js
import agconnect from '@hw-agconnect/core-harmony';
import remoteConfig from '@hw-agconnect/remoteconfig-harmony';

// 初始化AGC
agconnect.init({
  appName: 'YourApp',
  appVersion: '1.0.0'
});

// 获取远程配置
const config = remoteConfig.getInstance();
await config.fetch(0); // 0表示立即生效

3.2 版本检测逻辑

// utils/update.ts
import { checkUpdate } from '@hw-agconnect/appdistribution-harmony';

export async function checkGrayUpdate() {
  const result = await checkUpdate({
    strategy: 'gray_release', // 使用灰度策略
    forceCheck: true
  });
  
  if (result.isUpdateAvailable) {
    // 显示自定义更新弹窗
    showUpdateDialog(result.releaseNotes);
  }
}

4. 动态功能开关

4.1 远程配置读取

// features/flags.ts
export async function getFeatureFlag(feature: string): Promise<boolean> {
  const config = remoteConfig.getInstance();
  return config.getValue(feature).asBoolean();
}

// 使用示例
const isNewUIEnabled = await getFeatureFlag('new_home_ui');

4.2 条件渲染组件

<template>
  <div>
    <OldHomePage v-if="!isNewUIEnabled" />
    <NewHomePage v-else />
  </div>
</template>

<script>
export default {
  data() {
    return {
      isNewUIEnabled: false
    };
  },
  async created() {
    this.isNewUIEnabled = await getFeatureFlag('new_home_ui');
  }
};
</script>

5. 数据监控与告警

5.1 关键指标埋点

// analytics.js
import { Analytics } from '@hw-agconnect/analytics-harmony';

export function trackEvent(event: string, params: object) {
  Analytics.onEvent(event, {
    ...params,
    gray_group: window.__GRAY_GROUP__, // 注入灰度分组信息
    app_version: appVersion
  });
}

// 页面停留时间统计
export function trackPageView(page: string) {
  const startTime = Date.now();
  onUnload(() => {
    trackEvent('page_duration', {
      page,
      duration: Date.now() - startTime
    });
  });
}

5.2 自动告警规则

// alert-rules.json
{
  "rules": [
    {
      "name": "高崩溃率告警",
      "metric": "crash_rate",
      "condition": ">1%",
      "duration": "1h",
      "actions": [
        {
          "type": "email",
          "target": "dev-team@company.com"
        },
        {
          "type": "rollback",
          "phase": "previous"
        }
      ]
    }
  ]
}

6. 渐进式发布控制

6.1 分阶段激活功能

// feature-rollout.js
import { RemoteConfig } from '@hw-agconnect/remoteconfig-harmony';

export async function activateFeature(feature: string) {
  const config = RemoteConfig.getInstance();
  await config.fetchAndActivate();
  
  const percentage = config.getValue(`${feature}_rollout`).asNumber();
  const userHash = getUserHash(); // 获取用户唯一哈希
  
  return userHash % 100 < percentage;
}

6.2 设备定向策略

// device-targeting.ts
export async function shouldEnableFeature(feature: string): Promise<boolean> {
  const deviceInfo = await getDeviceInfo();
  const rules = await fetchTargetingRules(feature);
  
  return rules.some(rule => 
    rule.models.includes(deviceInfo.model) &&
    rule.regions.includes(deviceInfo.region) &&
    rule.osVersions.some(v => deviceInfo.osVersion >= v)
  );
}

7. 回滚机制实现

7.1 自动回滚检测

// rollback-monitor.ts
import { Crash } from '@hw-agconnect/crash-harmony';

export function startRollbackMonitor() {
  Crash.onCriticalError(async (error) => {
    if (error.fatalCount > 10) {
      await triggerRollback();
    }
  });
}

async function triggerRollback() {
  const config = remoteConfig.getInstance();
  await config.rollback('previous_stable');
}

7.2 降级兼容方案

// fallback.js
export function withFallback(feature, fallback) {
  try {
    return feature();
  } catch (error) {
    trackEvent('feature_fallback', { error });
    return fallback();
  }
}

// 使用示例
const result = await withFallback(
  () => fetchNewAPI(),
  () => fetchLegacyAPI()
);

8. 全流程示例

8.1 灰度发布工作流

8.2 关键代码集成

// app.vue
export default {
  async mounted() {
    // 检查灰度更新
    await checkGrayUpdate();
    
    // 初始化功能开关
    this.isNewUIEnabled = await getFeatureFlag('new_home_ui');
    
    // 启动监控
    startRollbackMonitor();
  }
}

9. 验证与调试

9.1 强制加入灰度组

// debug.js
// 开发阶段强制指定灰度组
if (process.env.NODE_ENV === 'development') {
  window.__GRAY_GROUP__ = 'alpha';
}

9.2 本地模拟策略

// mock-gray-response.json
{
  "isUpdateAvailable": true,
  "versionCode": 203,
  "releaseNotes": "测试灰度版本",
  "grayGroup": "alpha"
}

10. 性能与安全

10.1 数据加密传输

// secure-fetch.js
import { Crypto } from '@hw-agconnect/crypto-harmony';

export async function secureFetch(url, data) {
  const encrypted = await Crypto.encrypt({
    data: JSON.stringify(data),
    key: 'your-encryption-key'
  });
  
  return fetch(url, {
    headers: {
      'Content-Type': 'application/encrypted-json'
    },
    body: encrypted
  });
}

10.2 最小权限控制

<!-- config.xml -->
<feature name="grayUpdate">
  <permission>ohos.permission.APP_DISTRIBUTION</permission>
  <permission>ohos.permission.NETWORK</permission>
</feature>

通过本方案可实现：

精准控制 更新范围（设备型号/地区/用户比例）
实时监控 关键业务指标
自动决策 发布或回滚
无缝集成 现有Uniapp工程
