图1：用户分群推送测试系统架构（包含标签管理、推送测试和效果分析模块）

核心代码实现
标签用户管理服务 (ArkTS)

// 用户标签管理服务
class UserTagService {
private static instance: UserTagService;
private taggedUsers: Map<string, UserTagInfo> = new Map();

// 单例模式
static getInstance(): UserTagService {
if (!UserTagService.instance) {
UserTagService.instance = new UserTagService();
return UserTagService.instance;

// 添加用户标签

async tagUser(userId: string, tags: string[]) {
const userInfo = this.taggedUsers.get(userId) || { userId, tags: [] };

// 合并去重
userInfo.tags = [...new Set([...userInfo.tags, ...tags])];
this.taggedUsers.set(userId, userInfo);

// 同步标签变更
await this.syncUserTags(userId);

// 获取标签用户组

getUsersByTag(tag: string): UserTagInfo[] {
return Array.from(this.taggedUsers.values())
.filter(user => user.tags.includes(tag));
// 同步用户标签

private async syncUserTags(userId: string) {
const userInfo = this.taggedUsers.get(userId);
if (!userInfo) return;

await DistributedPushSync.sendUserTagUpdate({
  type: 'user_tag_update',
  userId,
  tags: userInfo.tags,
  timestamp: Date.now(),
  deviceId: device.deviceInfo.deviceId
});

}

// 用户标签信息接口
interface UserTagInfo {
userId: string;
tags: string[];
lastActive?: number;
// 推送测试配置

interface PushTestConfig {
testId: string;
tag: string;
pushContent: PushContent;
sampleRate?: number;
scheduledTime?: number;
// 推送内容

interface PushContent {
title: string;
body: string;
data?: Record<string, any>;

推送测试执行器 (ArkTS)

// 推送测试执行服务
class PushTestService {
private static instance: PushTestService;
private activeTests: Map<string, PushTest> = new Map();
private backgroundTask: BackgroundTaskManager.Task | null = null;

static getInstance(): PushTestService {
if (!PushTestService.instance) {
PushTestService.instance = new PushTestService();
return PushTestService.instance;

// 启动推送测试

async startPushTest(config: PushTestConfig): Promise<string> {
const testId = this.generateTestId(config.tag);
const test: PushTest = {
id: testId,
config,
status: ‘preparing’,
startTime: Date.now(),
receivers: [],
results: []
};

this.activeTests.set(testId, test);

// 获取目标用户
const targetUsers = UserTagService.getInstance()
  .getUsersByTag(config.tag);

// 采样用户
const sampledUsers = this.sampleUsers(
  targetUsers, 
  config.sampleRate || 1.0
);

// 注册后台任务
this.registerBackgroundTask(testId);

// 执行推送
await this.executePushDelivery(testId, sampledUsers);

return testId;

// 执行推送分发

private async executePushDelivery(testId: string, users: UserTagInfo[]) {
const test = this.activeTests.get(testId);
if (!test) return;

test.status = 'delivering';
test.receivers = users.map(u => ({
  userId: u.userId,
  status: 'pending',
  receiveTime: 0
}));

// 分批推送
const batchSize = 100;
for (let i = 0; i < users.length; i += batchSize) {
  const batch = users.slice(i, i + batchSize);
  await this.sendPushBatch(test, batch);
  
  // 更新进度
  test.progress = Math.min(100, (i + batchSize) / users.length * 100);
  this.syncTestStatus(testId);

test.status = ‘delivered’;

this.syncTestStatus(testId);

// 注册后台任务

private registerBackgroundTask(testId: string) {
this.backgroundTask = backgroundTaskManager.start({
mode: BackgroundTaskManager.ProcessingMode.BATCH,
network: BackgroundTaskManager.NetworkType.ANY,
callback: () => {
this.monitorPushResults(testId);
});

// 监控推送结果

private async monitorPushResults(testId: string) {
const test = this.activeTests.get(testId);
if (!test) return;

// 模拟推送接收结果（实际对接推送服务回调）
test.receivers.forEach(receiver => {
  if (receiver.status === 'pending') {
    receiver.status = Math.random() > 0.1 ? 'received' : 'failed';
    receiver.receiveTime = Date.now();

});

test.status = 'completed';
this.syncTestStatus(testId);

// 分析测试结果
this.analyzeTestResults(testId);

}

// 推送测试状态
interface PushTest {
id: string;
config: PushTestConfig;
status: ‘preparing’ ‘delivering’ ‘delivered’
‘completed’;
startTime: number;
endTime?: number;
progress?: number;
receivers: PushReceiver[];
results?: PushTestResult[];
// 推送接收者状态

interface PushReceiver {
userId: string;
status: ‘pending’ ‘received’
‘failed’;
receiveTime: number;

分布式推送同步服务 (Java)

// 分布式推送同步服务
public class DistributedPushSync {
private static final String SYNC_CHANNEL = “push_sync_channel”;
private static DistributedPushSync instance;
private final DeviceManager deviceManager;

private DistributedPushSync(Context context) {
    this.deviceManager = DeviceManager.getInstance(context);
    setupSyncChannel();

public static synchronized DistributedPushSync getInstance(Context context) {

    if (instance == null) {
        instance = new DistributedPushSync(context);

return instance;

// 发送用户标签更新

public static void sendUserTagUpdate(UserTagMessage message) throws SyncException {
    byte[] data = message.toBytes();
    List<Device> tagManagers = getTagManagerDevices();
    
    for (Device device : tagManagers) {
        instance.deviceManager.send(device, SYNC_CHANNEL, data);

}

// 发送推送测试状态
public static void sendPushTestStatus(PushTestMessage message) throws SyncException {
    byte[] data = message.toBytes();
    List<Device> observers = getObserverDevices();
    
    for (Device device : observers) {
        instance.deviceManager.send(device, SYNC_CHANNEL, data);

}

// 处理同步消息
private void handleSyncMessage(Device sender, byte[] data) {
    PushSyncMessage message = PushSyncMessage.fromBytes(data);
    
    switch (message.getType()) {
        case "user_tag_update":
            processUserTagUpdate((UserTagMessage) message);
            break;
        case "push_test_status":
            processPushTestStatus((PushTestMessage) message);
            break;

}

// 推送同步消息基类
public abstract static class PushSyncMessage implements Serializable {
    protected String type;
    protected String deviceId;
    protected long timestamp;
    
    public byte[] toBytes() {
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        try (ObjectOutputStream oos = new ObjectOutputStream(bos)) {
            oos.writeObject(this);
            return bos.toByteArray();

catch (IOException e) {

            return new byte[0];

}

    public static PushSyncMessage fromBytes(byte[] data) {
        try (ObjectInputStream ois = 
             new ObjectInputStream(new ByteArrayInputStream(data))) {
            return (PushSyncMessage) ois.readObject();

catch (Exception e) {

            return null;

}

}

推送效果分析引擎 (ArkTS)

// 推送效果分析服务
class PushAnalysisService {
private static instance: PushAnalysisService;
private testResults: Map<string, PushTestResult> = new Map();

static getInstance(): PushAnalysisService {
if (!PushAnalysisService.instance) {
PushAnalysisService.instance = new PushAnalysisService();
return PushAnalysisService.instance;

// 分析测试结果

analyzeTestResults(testId: string): PushTestResult {
const test = PushTestService.getInstance().getTest(testId);
if (!test) throw new Error(‘测试不存在’);

const receivers = test.receivers;
const total = receivers.length;
const received = receivers.filter(r => r.status === 'received').length;
const failed = total - received;

const deliveryRate = total > 0 ? (received / total) * 100 : 0;
const avgDeliveryTime = this.calculateAverageDeliveryTime(receivers);

const result: PushTestResult = {
  testId,
  tag: test.config.tag,
  totalUsers: total,
  receivedUsers: received,
  deliveryRate,
  avgDeliveryTime,
  deviceBreakdown: this.calculateDeviceBreakdown(receivers)
};

this.testResults.set(testId, result);
this.syncAnalysisResult(testId);

return result;

// 计算平均送达时间

private calculateAverageDeliveryTime(receivers: PushReceiver[]): number {
const received = receivers.filter(r => r.status === ‘received’);
if (received.length === 0) return 0;

const totalTime = received.reduce((sum, r) => {
  return sum + (r.receiveTime - r.receiveTime);
}, 0);

return totalTime / received.length;

// 计算设备分布

private calculateDeviceBreakdown(receivers: PushReceiver[]): DeviceBreakdown[] {
// 实际实现中从用户信息获取设备类型
return [
deviceType: ‘phone’, count: receivers.length * 0.7 },

deviceType: ‘tablet’, count: receivers.length * 0.2 },

deviceType: ‘tv’, count: receivers.length * 0.1 }

];

}

// 推送测试结果
interface PushTestResult {
testId: string;
tag: string;
totalUsers: number;
receivedUsers: number;
deliveryRate: number;
avgDeliveryTime: number;
deviceBreakdown: DeviceBreakdown[];
// 设备分布

interface DeviceBreakdown {
deviceType: string;
count: number;

关键技术实现
HarmonyOS 5后台任务管理

// 后台任务管理器封装
class BackgroundTaskHelper {
private static instance: BackgroundTaskHelper;
private taskMap: Map<string, BackgroundTaskManager.Task> = new Map();

static getInstance(): BackgroundTaskHelper {
if (!BackgroundTaskHelper.instance) {
BackgroundTaskHelper.instance = new BackgroundTaskHelper();
return BackgroundTaskHelper.instance;

// 注册推送结果监控任务

registerPushMonitorTask(testId: string): Promise<void> {
return new Promise((resolve, reject) => {
try {
const task = backgroundTaskManager.start({
mode: BackgroundTaskManager.ProcessingMode.BATCH,
network: BackgroundTaskManager.NetworkType.ANY,
callback: () => {
PushTestService.getInstance().monitorPushResults(testId);
});

    this.taskMap.set(testId, task);
    resolve();

catch (error) {

    reject(error);

});

// 更新任务网络状态

updateTaskNetwork(testId: string, networkType: BackgroundTaskManager.NetworkType) {
const task = this.taskMap.get(testId);
if (task) {
task.setNetwork(networkType);
}

// 停止后台任务
stopTask(testId: string) {
const task = this.taskMap.get(testId);
if (task) {
task.stop();
this.taskMap.delete(testId);
}

多设备标签同步

// 多设备标签协调器
class MultiDeviceTagCoordinator {
private static instance: MultiDeviceTagCoordinator;
private deviceTagStates: Map<string, DeviceTagState> = new Map();

static getInstance(): MultiDeviceTagCoordinator {
if (!MultiDeviceTagCoordinator.instance) {
MultiDeviceTagCoordinator.instance = new MultiDeviceTagCoordinator();
return MultiDeviceTagCoordinator.instance;

// 同步标签到所有设备

async syncTagsToAllDevices(userId: string, tags: string[]) {
const devices = await getConnectedDevices();
const currentDevice = device.deviceInfo.deviceId;

// 过滤掉当前设备
const targetDevices = devices.filter(d => d.deviceId !== currentDevice);

// 并行同步
await Promise.all(targetDevices.map(device => {
  return DistributedPushSync.sendUserTagUpdate({
    type: 'user_tag_update',
    userId,
    tags,
    timestamp: Date.now(),
    deviceId: currentDevice
  });
}));

// 处理标签冲突

resolveTagConflict(userId: string, conflictingTags: Map<string, string[]>): string[] {
// 实现标签冲突解决策略（如时间戳最新优先）
const latest = Array.from(conflictingTags.entries())
.sort((a, b) => b[1].timestamp - a[1].timestamp)[0];

return latest[1].tags;

}

// 设备标签状态
interface DeviceTagState {
deviceId: string;
userId: string;
tags: string[];
timestamp: number;

推送到达率计算

// 推送指标计算器
class PushMetricsCalculator {
// 计算推送到达率
static calculateDeliveryRate(test: PushTest): number {
const received = test.receivers.filter(r => r.status === ‘received’).length;
return test.receivers.length > 0 ? (received / test.receivers.length) * 100 : 0;
// 计算分位数送达时间

static calculateDeliveryPercentiles(test: PushTest): DeliveryPercentiles {
const received = test.receivers
.filter(r => r.status === ‘received’)
.map(r => r.receiveTime - test.startTime)
.sort((a, b) => a - b);

return {
  p50: this.getPercentile(received, 50),
  p90: this.getPercentile(received, 90),
  p95: this.getPercentile(received, 95)
};

// 计算设备类型送达率

static calculateDeviceDeliveryRates(test: PushTest): DeviceDeliveryRate[] {
// 按设备类型分组统计（实际实现中需要真实设备类型数据）
return [
deviceType: ‘phone’, deliveryRate: 0.95 },

deviceType: ‘tablet’, deliveryRate: 0.85 },

deviceType: ‘tv’, deliveryRate: 0.75 }

];

}

// 送达时间分位数
interface DeliveryPercentiles {
p50: number;
p90: number;
p95: number;
// 设备送达率

interface DeviceDeliveryRate {
deviceType: string;
deliveryRate: number;

应用场景示例
执行分群推送测试

// 执行标签用户推送测试
async function runTaggedPushTest() {
// 1. 定义测试配置
const testConfig: PushTestConfig = {
testId: ‘test_’ + Date.now(),
tag: ‘premium_users’,
pushContent: {
title: ‘尊享优惠’,
body: ‘尊敬的会员，您有专属优惠待领取！’,
data: { promo_code: ‘VIP2023’ }
},
sampleRate: 0.2 // 20%采样
};

// 2. 启动推送测试
const testId = await PushTestService.getInstance()
.startPushTest(testConfig);

// 3. 监控测试进度
PushTestService.getInstance().subscribe(testId, {
onProgress: (progress) => {
updateTestProgressUI(testId, progress);
},
onCompleted: (result) => {
showTestResultUI(result);
});

return testId;
// 在后台任务中监控推送结果

backgroundTaskManager.register(‘push_monitor’, async () => {
const activeTests = PushTestService.getInstance().getActiveTests();

for (const testId of activeTests) {
await PushTestService.getInstance()
.monitorPushResults(testId);
});

多设备标签同步测试

// 测试多设备标签同步
async function testMultiDeviceTagSync() {
// 1. 在设备A上添加标签
await UserTagService.getInstance()
.tagUser(‘user123’, [‘premium’, ‘high_value’]);

// 2. 验证设备B上的标签状态
const devices = await getConnectedDevices();
const deviceB = devices.find(d => d.deviceId === ‘deviceB_id’);

if (deviceB) {
const tagsOnB = await DistributedPushSync.requestUserTags(
‘user123’,
deviceB.deviceId
);

console.log('设备B上的标签:', tagsOnB);
assert(tagsOnB.includes('premium'));

}
