From 2f172664557199cc507152ebceda46ed7677a91a Mon Sep 17 00:00:00 2001 From: hailin Date: Sat, 7 Mar 2026 21:15:27 -0800 Subject: [PATCH] feat(referral): implement full referral system across all layers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Overview 完整实现 IT0 推荐裂变系统，涵盖后端微服务、基础设施、Flutter 移动端、Next.js Web Admin。 ## Backend — referral-service (packages/services/referral-service/) ### 架构设计 - 遵循 billing-service 模式：DataSource 直接访问 public schema（非 TenantAwareRepository） - 推荐单元为租户级别（tenant-level），不区分租户内用户 - 最大 2 层推荐深度（L1 直接推荐 / L2 间接推荐） - 推荐码格式：`IT0-{tenantPrefix3}-{random4}` 例：`IT0-ACM-X9K2` ### 领域实体（5个，均在 public schema） - `referral_codes`：每个租户唯一推荐码，记录点击量 - `referral_relationships`：推荐关系，状态流转 PENDING→ACTIVE→REWARDED→EXPIRED - `referral_rewards`：积分奖励记录，支持 PENDING/APPLIED/EXPIRED - `referral_stats`：每租户聚合统计（直推数、积分总量等） - `referral_processed_events`：Redis Stream 幂等性去重表 ### 奖励规则 - Pro 套餐首次付款：推荐人 $15（1500分）/ 被推荐人 $5（500分） - Enterprise 套餐首次付款：推荐人 $50（5000分）/ 被推荐人 $20（2000分） - 续订奖励：付款金额 10%，最多持续 12 个月 - 奖励触发：监听 Redis Stream `events:payment.received`，消费者组 `referral-service` ### Use Cases（6个） - `GetMyReferralInfoUseCase`：获取/自动创建推荐码，返回分享链接 - `ValidateReferralCodeUseCase`：验证码格式 + 存在性（公开接口，注册前使用） - `RegisterWithCodeUseCase`：注册时绑定推荐关系，防止自推荐/重复注册 - `ConsumePaymentReceivedUseCase`：消费支付事件，发放首次/续订奖励，含幂等保护 - `GetReferralListUseCase`：分页查询推荐列表和奖励记录 - `GetPendingCreditsUseCase`：供 billing-service 查询待抵扣积分并标记已使用 ### REST Controllers（3个） - `ReferralController` (/api/v1/referral)：用户端，JWT 验证 - GET /me — 我的推荐码与统计 - GET /me/referrals — 我的推荐列表（分页） - GET /me/rewards — 我的奖励记录（分页） - GET /validate?code=xxx — 公开验证推荐码（注册页使用） - `ReferralInternalController` (/api/v1/referral/internal)：服务间调用，X-Internal-Api-Key 验证 - POST /register — auth-service 注册后回调，绑定推荐关系 - GET /:tenantId/pending-credits — billing-service 查询待抵扣金额 - POST /:tenantId/apply-credits — billing-service 账单生成后标记积分已使用 - `ReferralAdminController` (/api/v1/referral/admin)：管理员端，JWT + platform_admin 角色 - GET /relationships — 全量推荐关系（可按状态过滤，分页） - GET /rewards — 全量奖励记录（可按状态过滤，分页） - GET /stats — 平台汇总统计 ## Infrastructure ### database migration (packages/shared/database/migrations/006-create-referral-tables.sql) 创建 5 张表，含必要索引（tenantId、code、status、createdAt） ### docker-compose.yml 新增 referral-service 服务定义（port 13012:3012），healthcheck 基于 HTTP 200， api-gateway depends_on 中添加 referral-service healthy 条件 ### kong.yml (packages/gateway/config/kong.yml) 新增 3 组路由： - `referral-routes`：/api/v1/referral（JWT 插件，转发用户请求） - `referral-admin-routes`：/api/v1/referral/admin（JWT 插件，管理员） - `referral-validate-public`：/api/v1/referral/validate（无 JWT，注册页调用） 注：internal 路由不暴露到 Kong，仅服务间直接调用 ## auth-service 集成 (packages/services/auth-service/src/application/services/auth.service.ts) 注册成功后（register + registerWithNewTenant 两个路径）fire-and-forget 调用 referral-service 内部接口 POST /api/v1/referral/internal/register， 传入 tenantId + referralCode（可选），使用 Node.js 内置 http 模块（无新依赖） ## Flutter 移动端 (it0_app/lib/features/referral/) ### 数据层 - `referral_info.dart`：ReferralInfo / ReferralItem / RewardItem 模型，含格式化 getter - `referral_repository.dart`：Dio HTTP 请求 + Riverpod referralRepositoryProvider ### 状态管理（Riverpod FutureProvider） - referralInfoProvider — 推荐码信息 - referralListProvider — 直推列表首页 - pendingRewardsProvider — 待抵扣奖励 - allRewardsProvider — 完整奖励历史 ### UI（referral_screen.dart，630行） - _ReferralCodeCard：推荐码展示 + 一键复制 + 系统分享（Share.share） - _StatsRow：3格统计卡（直推数 / 已激活 / 待抵扣积分） - _RewardRulesCard：奖励规则说明卡片 - _ReferralPreviewList + _RewardPreviewList：首页预览 + "查看全部"导航 - _ReferralListPage + _RewardListPage：完整分页列表子页面 ### 入口集成 - profile_page.dart：Billing 分组新增"邀请有礼"设置行（Gift 图标） - app_router.dart：ShellRoute 内新增 /referral 路由 → ReferralScreen ## Web Admin (it0-web-admin/) ### 数据层 - `src/domain/entities/referral.ts`：TypeScript 接口定义（ReferralRelationship / ReferralReward / ReferralAdminStats / PaginatedResult） - `src/infrastructure/repositories/api-referral.repository.ts`：React Query 数据获取函数（getAdminReferralStats / listAdminRelationships / listAdminRewards） ### 管理页面 (src/app/(admin)/referral/page.tsx) 3 Tab 布局（概览 / 推荐关系 / 积分奖励）： - StatsOverview：3张统计卡（总推荐数 / 已激活 / 待领积分记录） - RelationshipsTable：状态筛选下拉 + 分页表格（推荐人、被推荐人租户ID、推荐码、层级、状态、时间） - RewardsTable：状态筛选下拉 + 分页表格（受益租户、金额、触发类型、状态、来源账单、时间） - StatusBadge：彩色状态标签组件（PENDING/ACTIVE/REWARDED/EXPIRED/APPLIED） ### 导航集成 - sidebar.tsx：platformAdminItems 新增"推荐管理"（Gift 图标，/referral 路由） - i18n/locales/zh/sidebar.json：新增 "referral": "推荐管理" - i18n/locales/en/sidebar.json：新增 "referral": "Referrals" ## 部署说明 1. 服务器执行数据库迁移： psql -U it0 -d it0 -f packages/shared/database/migrations/006-create-referral-tables.sql 2. 重建并启动新服务： docker compose build referral-service api-gateway && docker compose up -d 3. 确认 .env 中设置 INTERNAL_API_KEY（服务间认证密钥）
