docs: reorganize api docs into categorized subdirectories and fill missing docs - Categorize 77 existing api docs into 16 business-domain subdirectories (auth/ad/wallet/coupon/compare/savings/signin/tasks/invite/user/ device/platform/intent/meituan/other) plus admin/ and internal/ - Split admin/ into 7 sub-resource subdirectories (auth/users/wallet/ withdraws/feedbacks/admins/ad) with 4 single-file docs at root - Create 21 new docs covering 28 previously undocumented endpoints: ad/watch-report, wallet/transfer-auth (3 endpoints), coupon/session+ stats+completed-today+prompt (7), invite/me+invitees+bind+landing-track, user/onboarding (2), platform/flags+ad-config+app-version, intent/step+precoupon/step, analytics/events, order/report, report/submit+records, feedback/config+records, trace/finalize - Add mock request/response JSON examples to all new docs - Create docs/README.md with full category index for LLM navigation - Update docs/api/README.md: fix all links, add new endpoint rows, replace "no doc" markers with actual links - Fix back-navigation links (./README.md -> ../README.md or ../../README.md) in all moved files @

# POST /admin/api/users/{user_id}/cash — 手动增减/设值现金(带审计)
|
||
|
||
> 所属:Admin·用户 组（前缀 `/admin/api/users`） | 鉴权:Bearer admin_token（角色:`finance`,`super_admin` 恒通过) | [← 返回 API 索引](../../README.md)
|
||
|
||
主要用于给无现金用户直接发钱、好让其测试提现链路。
|
||
|
||
## 入参
|
||
- 路径:`user_id`(int)
|
||
- **application/json**:
|
||
| 字段 | 类型 | 必填 | 说明 |
|
||
|---|---|---|---|
|
||
| `mode` | string | ✗ | `delta`(默认)=增减 / `set`=设为指定值 |
|
||
| `amount_cents` | int | ✓ | `delta` 模式:现金变动(分,正=发放,负=扣减,不可为 0);`set` 模式:目标现金值(分,须 ≥ 0) |
|
||
| `reason` | string | ✓ | 操作原因,1–128 字(必填,入审计与流水备注) |
|
||
|
||
## 出参
|
||
响应 `200`:`OkResponse` = `{ "ok": true }`
|
||
|
||
## 错误码
|
||
- `400`(`delta`)`amount_cents == 0`(`detail: "amount_cents 不能为 0"`);或负数扣减后余额会变负(`detail: "扣减后现金为负(当前余额 N 分)"`)
|
||
- `400`(`set`)目标值为负(`detail: "目标现金值不能为负"`);或目标值等于当前余额(`detail: "当前现金已为 N 分,无需调整"`)
|
||
- `401` 未带/无效/过期 admin token、管理员被禁用(头带 `WWW-Authenticate: Bearer`)
|
||
- `403` 角色不足(需 `finance` 或 `super_admin`)
|
||
- `404` 用户不存在(`detail: "用户不存在"`)
|
||
- `422` 缺 `amount_cents`/`reason`、`reason` 长度不在 1–128、`mode` 非 `delta`/`set`、字段类型不合法 / `user_id` 非整数
|
||
|
||
## 说明
|
||
- 金额单位一律为**分**(`*_cents`);本接口只动现金余额,不涉及金币。
|
||
- **set 模式**:读当前余额算出差值 `delta = target - 当前余额`,再复用同一套写入逻辑(故只写一笔差值流水)。目标值须 ≥ 0;差值为 0(已等于目标)直接拒绝。
|
||
- 扣减保护:实际写入的 `delta < 0` 时若扣减后现金余额 < 0 直接拒绝(运营误操作保护);set 模式目标值 ≥ 0 天然不会扣成负。
|
||
- 现金变动写流水 [cash_transaction](../database/cash_transaction.md):`biz_type` 实际差值为正记 `admin_grant`、为负记 `admin_deduct`(set 模式同理,不新增流水类型),`remark = admin:<reason>`(截断至 128 字)。
|
||
- 写操作记审计 [admin_audit_log](../database/admin_audit_log.md):`action = user.cash.grant`,`target_type = user`,`target_id = user_id`,`detail = {amount_cents(=实际差值), balance_after_cents, reason}`;set 模式额外带 `{mode:"set", target_cents, before_cents}`。并记录操作 IP。
|
||
- 现金变动 + 审计在同一事务原子提交(改钱必留痕)。
|
||
- 关联用户表 [user](../database/user.md);现金账户 [coin_account](../database/coin_account.md);现金流水 [cash_transaction](../database/cash_transaction.md)。
