# VIP / Credits Frontend API
|
|
|
|
本文档是前端接入会员、积分、权益和历史解锁的推荐接口说明。新版接入原则:
|
|
|
|
- 前端权益状态只认 `GET /api/user/entitlements`。
|
|
- 游客和登录非会员权益一致,只按 `isVip` 区分会员/非会员。
|
|
- 支付完成后只刷新一次 `GET /api/user/entitlements`。
|
|
- `dolBalance` 是旧字段名,等价于 `creditBalance`,新代码优先使用 `creditBalance`。
|
|
|
|
## 推荐调用链
|
|
|
|
```text
|
|
打开充值/VIP 弹窗
|
|
-> GET /api/payment/plans
|
|
-> POST /api/payment/create-order
|
|
-> 打开 data.payParams.url / checkout_url / payment_url
|
|
-> GET /api/payment/order-status 轮询,或等待 WebSocket payment_success
|
|
-> GET /api/user/entitlements 刷新权益
|
|
```
|
|
|
|
不要再按订单类型分别调用 `/api/payment/vip-status` 和 `/api/user/credits` 刷新状态。
|
|
|
|
## GET /api/user/entitlements
|
|
|
|
用途:当前用户 VIP、积分和权益快照。支持游客 token 和登录 token。
|
|
|
|
认证:需要 `Authorization: Bearer <token>`,游客 token 也可以。
|
|
|
|
响应示例:
|
|
|
|
```json
|
|
{
|
|
"success": true,
|
|
"data": {
|
|
"userId": "user-1",
|
|
"isGuest": false,
|
|
"isVip": false,
|
|
"vipExpiresAt": null,
|
|
"creditBalance": 120,
|
|
"dolBalance": 120,
|
|
"policy": {
|
|
"membershipState": "non_vip",
|
|
"nonVipEntitlementsShared": true,
|
|
"guestSameAsLoggedInNonVip": true,
|
|
"refreshAfterPayment": "GET /api/user/entitlements"
|
|
},
|
|
"costs": {
|
|
"normal_message": 2,
|
|
"private_message": 10,
|
|
"voice_message": 20,
|
|
"photo": 40,
|
|
"voice_call_minute": 50,
|
|
"private_album_10": 300,
|
|
"private_album_20": 600
|
|
},
|
|
"quotas": {
|
|
"normalChatFreeDaily": 30,
|
|
"privateUnlockFreeDaily": 1,
|
|
"voiceMessageFreeDaily": 0,
|
|
"photoFreeDaily": 0
|
|
},
|
|
"historyUnlock": {
|
|
"enabled": true,
|
|
"order": "oldest_first",
|
|
"chargeMode": "highest_cost_per_locked_message",
|
|
"insufficientBalanceBehavior": "no_deduction",
|
|
"costs": {
|
|
"private_message": 10,
|
|
"voice_message": 20,
|
|
"photo": 40
|
|
}
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
前端使用:
|
|
|
|
- App 启动、登录成功、游客 token 创建成功后调用。
|
|
- 支付成功、充值成功、历史解锁成功后调用。
|
|
- `isGuest` 只用于 UI 身份展示,不用于权益判断。
|
|
|
|
## GET /api/payment/plans
|
|
|
|
用途:获取当前国家对应的会员/积分套餐。
|
|
|
|
认证:不需要登录。后端通过 `CF-IPCountry` 判断国家;登录后创建订单会再次按用户国家校验价格。
|
|
|
|
响应重点字段:
|
|
|
|
```json
|
|
{
|
|
"plan_id": "vip_monthly",
|
|
"plan_name": "月度会员",
|
|
"order_type": "vip_monthly",
|
|
"amount_cents": 1999,
|
|
"original_amount_cents": 1999,
|
|
"daily_price_cents": 66,
|
|
"currency": "USD",
|
|
"pricing_tier": "T1",
|
|
"vip_days": 30,
|
|
"dol_amount": null
|
|
}
|
|
```
|
|
|
|
字段说明:
|
|
|
|
- `amount_cents`: 实付金额,传给支付服务。
|
|
- `original_amount_cents`: 划线价;无划线价时为 `null`,字段一定存在。
|
|
- `currency`: 支付币种。
|
|
- `plan_id`: 创建订单时传回后端。
|
|
|
|
## POST /api/payment/create-order
|
|
|
|
用途:创建支付订单。
|
|
|
|
认证:需要登录 token。
|
|
|
|
请求:
|
|
|
|
```json
|
|
{
|
|
"planId": "vip_monthly",
|
|
"payChannel": "stripe",
|
|
"autoRenew": true
|
|
}
|
|
```
|
|
|
|
响应:
|
|
|
|
```json
|
|
{
|
|
"success": true,
|
|
"data": {
|
|
"orderId": "ord-1",
|
|
"payParams": {
|
|
"url": "https://pay.example/ord-1"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
前端使用:
|
|
|
|
- `planId` 必须来自 `/api/payment/plans`。
|
|
- `payParams` 原样交给支付 SDK 或打开其中的支付 URL。
|
|
- 后端创建订单时使用 plans 里的 `amount_cents/currency`,不会再固定覆盖成 CNY。
|
|
|
|
## GET /api/payment/order-status
|
|
|
|
用途:轮询支付订单状态。
|
|
|
|
认证:需要登录 token,只能查自己的订单。
|
|
|
|
请求:
|
|
|
|
```text
|
|
GET /api/payment/order-status?order_id=ord-1
|
|
```
|
|
|
|
响应:
|
|
|
|
```json
|
|
{
|
|
"success": true,
|
|
"data": {
|
|
"orderId": "ord-1",
|
|
"status": "paid",
|
|
"orderType": "vip",
|
|
"planId": "vip_monthly"
|
|
}
|
|
}
|
|
```
|
|
|
|
状态:
|
|
|
|
- `pending`: 支付处理中,继续轮询。
|
|
- `paid`: 支付成功,停止轮询并调用 `/api/user/entitlements`。
|
|
- `failed`: 支付失败,停止轮询并提示用户。
|
|
|
|
## WebSocket payment_success / payment_failed
|
|
|
|
用途:支付服务回调后,后端主动推送支付结果。
|
|
|
|
成功事件示例:
|
|
|
|
```json
|
|
{
|
|
"type": "payment_success",

|
|
}
|

```
|
|
|

|
"dolBalance": 1120
|
|
}
|
|
```
|
|
|
|
前端收到 `payment_success` 后:
|
|
|
|
```text
|
|
停止 order-status 轮询
|
|
-> GET /api/user/entitlements
|
|
-> 用 creditBalance/isVip 更新页面
|
|
```
|
|
|
|
## POST /api/chat/unlock-history

|
|
|
|
计费规则:
|
|
|
|
- 私密消息:10 credits。
|
|
- 语音消息:20 credits。
|
|
- 照片:40 credits。
|
|
- 同一条消息命中多个类型时,按最高成本计一次。
|
|
- 余额不足时不扣费、不解锁,只返回差额。
|
|
- 已解锁过的消息会跳过。
|
|
|
|
## 兼容接口
|
|
|
|
以下接口保留给旧前端,但新前端不推荐作为权益状态来源:
|
|
|
|
- `GET /api/payment/vip-status`: 只返回 `isVip/vipExpiresAt`。
|
|
- `GET /api/user/credits`: 只返回 `dolBalance`。
|
|
- `GET /api/user/stats`: 用户统计、亲密度、记忆等,不再用于支付后刷新权益。
|
|
|
|
## 测试证明
|
|
|
|
本地测试命令:
|
|
|
|
```powershell
|
|
.\.venv\Scripts\python.exe -m pytest -q tests/test_vip_credit_entitlements.py
|
|
.\.venv\Scripts\python.exe -m pytest -q tests/test_private_unlock.py tests/test_elio_image_paywall.py
|
|
```
|
|
|
|
已通过结果:
|
|
|
|
```text
|
|
tests/test_vip_credit_entitlements.py: 13 passed
|
|
tests/test_private_unlock.py tests/test_elio_image_paywall.py: 11 passed
|
|
```
|
|
|
|
覆盖证明:
|
|
|
|
- `/api/user/entitlements`: 已测游客、登录非会员、VIP;游客和登录非会员的 `policy/costs/quotas` 一致。
|
|
- `/api/payment/plans`: 已测 T1/T2 国家;所有计划都有 `original_amount_cents`。
|
|
- `/api/payment/create-order`: 已测国家价格计划会传入创建订单;支付服务收到的金额和币种来自 plan。
|
|
- `/api/payment/order-status`: 已测 `pending/paid/failed` 和禁止查询他人订单。
|
|
- WebSocket `payment_success`: 已测 VIP 和积分发放事件 payload。
|
|
- `/api/chat/unlock-history`: 已测无锁定消息、余额不足不扣费、余额充足扣费、已解锁跳过。
|
|
- 兼容接口:已测 `/api/payment/vip-status` 和 `/api/user/credits` 仍可用。
