|
## 核心变更
|
|||
|
|
|
|||
|
|
### 数据模型（V024）
|
|||
|
|
|
|||
|
|
**新建 `activity_mutual_connection_consents` 表：**
|
|||
|
|
- 每对用户在同一个活动中有一条独立记录
|
|||
|
|
- 分别追踪 `user_a_status` 和 `user_b_status`（pending/accepted/declined）
|
|||
|
|
- 双方都 accepted 时设置 `both_confirmed_at`
|
|||
|
|
- UNIQUE 约束使用 `LEAST/GREATEST` 保证 (A,B) 和 (B,A) 是同一对
|
|||
|
|
|
|||
|
|
### 不变量强制实现
|
|||
|
|
|
|||
|
|
| 不变量 | 实现方式 |
|
|||
|
|
|--------|----------|
|
|||
|
|
| INV-014: Activity Mutual 不能直接创建 Match | `confirmConnection()` 只更新 consent 状态，不自动创建 Match |
|
|||
|
|
| INV-015: 双方确认后才创建 Activity Match | `confirmActivityInterest()` 在 RelationshipService 中调用，仅在 bothConfirmed 时触发 |
|
|||
|
|
| INV-010: 复用已有 active Match | `hasActiveMatch()` 检查优先于新建 |
|
|||
|
|
| INV-010: prior Unmatch 新建 episode | `findLatestMatch()` 检查是否曾 unmatch |
|
|||
|
|
|
|||
|
|
### API 端点
|
|||
|
|
|
|||
|
|
| 方法 | 路径 | 说明 |
|
|||
|
|
|------|------|------|
|
|||
|
|
| GET | `/activities/{id}/mutual/results` | 检测双向互选结果 |
|
|||
|
|
| POST | `/activities/{id}/mutual/consent` | 创建互选同意记录 |
|
|||
|
|
| POST | `/activities/{id}/mutual/confirm` | 用户确认开启沟通 |
|
|||
|
|
| POST | `/activities/{id}/mutual/decline` | 用户拒绝 |
|
|||
|
|
| GET | `/activities/{id}/mutual/status/{partnerId}` | 查询个人同意状态 |
|
|||
|
|
| GET | `/mutual/my-results` | 获取我的互选结果列表 |
|
|||
|
|
|
|||
|
|
### Miniapp 页面
|
|||
|
|
|
|||
|
|
| 页面 | 编号 | 功能 |
|
|||
|
|
|------|------|------|
|
|||
|
|
| activity-mutual-result | U60 | 展示所有互选结果，已确认可开聊 |
|
|||
|
|
| activity-mutual-waiting | U61 | 单对互选详情页，支持确认/拒绝/等待状态 |
|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## 前端状态流转
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
[未表达] → [双方互选产生] → [等待确认] → [用户A确认] → [用户B确认] → [Match创建，可聊天]
|
|||
|
|
↓ ↓
|
|||
|
|
[用户A拒绝] [用户B拒绝] → [单向关闭]
|
|||
|
|
```
