HarmonyOS5 应用邀请奖励系统的AGC积分实现

以下为 ​​基于AGC积分系统实现HarmonyOS 5应用裂变增长的完整ArkTS解决方案​​，包含邀请链路、积分奖励和防作弊体系的代码示例：

---

1. 系统架构

---

2. 核心功能实现

2.1 邀请码生成器

// invite-code.ets
import { Crypto } from '@ohos.security';

export function generateInviteCode(userId: string): string {
  const hash = Crypto.hash(userId + Date.now(), 'SHA-256');
  return 'INV-' + hash.substring(0, 8).toUpperCase();
}

export function validateInviteCode(code: string): boolean {
  return /^INV-[A-Z0-9]{8}$/.test(code);
}

2.2 积分奖励服务

// reward-service.ets
import { Points } from '@hw-agconnect/points';

export class InviteRewarder {
  static async grantInviteReward(inviter: string, invitee: string) {
    // 发放邀请人奖励
    await Points.grant(inviter, {
      action: 'invite',
      amount: 500,
      memo: `邀请${invitee}注册`
    });
    
    // 发放被邀请人奖励
    await Points.grant(invitee, {
      action: 'invited',
      amount: 300,
      memo: `被${inviter}邀请`
    });
    
    // 记录邀请关系
    await Database.create('invite_records', {
      inviter,
      invitee,
      timestamp: Date.now()
    });
  }
}

---

3. 防作弊体系

3.1 设备指纹校验

// fraud-detection.ets
export async function checkFraudRisk(userId: string) {
  const device = await Device.getFingerprint();
  const risks = await FraudDetection.check({
    userId,
    deviceId: device.id,
    behaviors: [
      'invite_frequency',
      'device_duplicate'
    ]
  });
  
  if (risks.score > 0.7) {
    throw new Error('检测到异常行为');
  }
}

3.2 邀请链路监控

// invite-monitor.ets
export class InviteMonitor {
  private static INVITE_LIMIT = 20; // 每日上限
  
  static async trackInvite(userId: string) {
    const today = await Database.count('invite_records', {
      inviter: userId,
      date: new Date().toISOString().split('T')[0]
    });
    
    if (today >= this.INVITE_LIMIT) {
      throw new Error('今日邀请已达上限');
    }
  }
}

4. 积分兑换系统

4.1 兑换商城组件

// reward-shop.ets
@Component
struct RewardShop {
  @State items: RewardItem[] = [];
  
  aboutToAppear() {
    this.loadItems();
  }
  
  async loadItems() {
    this.items = await Points.getRewards();
  }
  
  build() {
    List() {
      ForEach(this.items, (item) => {
        ListItem() {
          RewardCard({
            item,
            onRedeem: () => this.redeem(item)
          })
        }
      })
    }
  }
  
  async redeem(item: RewardItem) {
    try {
      await Points.redeem(item.id);
      Alert.show('兑换成功');
    } catch (err) {
      Alert.show(err.message);
    }
  }
}

4.2 兑换记录查询

// redemption-history.ets
export async function getRedemptionHistory(userId: string) {
  return Database.query('point_redemptions', {
    where: { userId },
    orderBy: 'timestamp DESC',
    limit: 50
  });
}

5. 社交分享集成

5.1 多平台分享组件

// share-invite.ets
@Component
struct SharePanel {
  @State platforms = ['wechat', 'qq', 'sms'];
  
  build() {
    Row() {
      ForEach(this.platforms, (platform) => {
        Button(platform.toUpperCase())
          .onClick(() => this.share(platform))
      })
    }
  }
  
  private share(platform: string) {
    const message = `加入我获得奖励，邀请码：${User.current.inviteCode}`;
    SocialShare.send(platform, {
      text: message,
      image: 'assets/invite-banner.png'
    });
  }
}

5.2 深度链接处理

// deeplink-handler.ets
export function handleInviteLink(url: string) {
  const params = new URL(url).searchParams;
  const inviteCode = params.get('code');
  
  if (inviteCode && validateInviteCode(inviteCode)) {
    Navigation.navigate('register', { inviteCode });
  }
}

6. 数据看板

6.1 实时增长看板

// growth-dashboard.ets
@Component
struct GrowthDashboard {
  @State stats: GrowthStats = {};
  
  aboutToAppear() {
    this.loadStats();
    setInterval(() => this.loadStats(), 60000);
  }
  
  async loadStats() {
    this.stats = await Analytics.getGrowthMetrics({
      period: '24h',
      metrics: [
        'invites',
        'conversions',
        'points_issued'
      ]
    });
  }
  
  build() {
    Grid() {
      GridItem() {
        MetricCard('邀请数', this.stats.invites)
      }
      GridItem() {
        MetricCard('转化率', `${this.stats.conversionRate}%`)
      }
      GridItem() {
        MetricCard('积分发放', this.stats.pointsIssued)
      }
    }
  }
}

6.2 用户排行榜

// leaderboard.ets
export async function getTopInviters(limit = 10) {
  return Database.query('invite_leaderboard', {
    orderBy: 'invite_count DESC',
    limit
  });
}

7. 完整工作流示例

7.1 新用户注册流程

// registration.ets
export async function registerWithInvite(user: User, inviteCode?: string) {
  // 1. 基础注册
  await Auth.register(user);
  
  // 2. 处理邀请关系
  if (inviteCode) {
    const inviter = await Database.find('invite_codes', { code: inviteCode });
    if (inviter) {
      await InviteRewarder.grantInviteReward(inviter.userId, user.id);
    }
  }
  
  // 3. 发放新手积分
  await Points.grant(user.id, {
    action: 'register',
    amount: 200
  });
}

7.2 积分兑换流程

// redemption-workflow.ets
export async function redeemPoints(userId: string, rewardId: string) {
  // 1. 校验资格
  const reward = await Points.getReward(rewardId);
  const balance = await Points.getBalance(userId);
  
  if (balance < reward.cost) {
    throw new Error('积分不足');
  }
  
  // 2. 扣减积分
  await Points.deduct(userId, reward.cost, `兑换${reward.name}`);
  
  // 3. 发放实物/虚拟奖励
  await Fulfillment.deliverReward(userId, reward);
  
  // 4. 记录日志
  await Database.create('redemption_logs', {
    userId,
    rewardId,
    timestamp: Date.now()
  });
}

8. 关键配置参数

参数	说明	推荐值
invite_reward	单次邀请奖励积分	300-500
daily_invite_limit	每日邀请上限	20
min_redemption	最低兑换积分门槛	1000
reward_expiry	积分过期时间(天)	365

9. 防刷策略扩展

9.1 行为验证码

// captcha.ets
export async function verifyHuman() {
  const challenge = await Captcha.generate('slider');
  const result = await Captcha.verify(challenge.id);
  
  if (!result.success) {
    throw new Error('请完成人机验证');
  }
}

9.2 社交图谱分析

// social-graph.ets
export async function checkInviteRing(userId: string) {
  const graph = await SocialGraph.build(userId, {
    depth: 3,
    relation: 'invite'
  });
  
  return graph.detectCycles();
}
