## 简介
|
||||
本文件面向开发者与集成方,系统性梳理“创建与列表”相关接口的实现与使用规范,重点覆盖:
|
||||
- 通过 POST /api/v1/profile/ 创建新档案,请求体中必须包含 1-16 字符的角色名;可选皮肤ID与披风ID。
|
||||
- 系统在创建时自动将该档案设为用户活跃档案,并将该用户其他档案置为非活跃。
|
||||
- 通过 GET /api/v1/profile/ 获取当前用户所有档案列表,响应包含档案UUID、名称、活跃状态、关联材质等信息。
|
||||
- 结合 profile_service.go 中的 CheckProfileLimit 逻辑说明用户档案数量上限(默认5个)的控制机制。
|
||||
|
||||
## 项目结构
|
||||
围绕档案模块的路由、处理器、服务层、仓储层与模型如下所示:

## 核心组件
|
||||
- 路由注册:在路由层为档案模块注册了认证中间件保护的 POST / GET / PUT / DELETE / POST activate 等路径。
|
||||
- 处理器:负责解析请求、鉴权、调用服务层并返回统一响应。
|
||||
- 服务层:封装业务规则,如创建档案时的用户存在性校验、角色名唯一性校验、活跃状态设置、档案数量上限检查等。
|
||||
- 仓储层:封装数据库访问,如创建档案、查询用户档案列表、批量设置活跃状态等。
|
||||
- 模型与类型:定义档案实体、响应结构、请求体结构以及材质类型。

|
||||
- 请求
|
||||
- 方法:GET
|

### 档案数量上限与活跃状态控制
|
||||
- 档案数量上限
|
||||
- 默认上限为5个,来源于系统配置与处理器中的硬编码值。
|
||||
- 服务层提供 CheckProfileLimit(userID, maxProfiles) 进行检查。
|
||||
- 活跃状态控制
|
||||
- 创建新档案时,服务层会将该档案设为活跃,并通过仓储层的事务将该用户其他档案置为非活跃。
|
||||
- 提供 SetActiveProfile 接口用于手动切换活跃档案。
|
||||
|
||||
```mermaid
|
||||
flowchart TD
|
||||
A["创建/切换活跃"] --> B["CheckProfileLimit(userID, 5)"]

D --> E["SetActiveProfile(uuid, userID) 事务"]
|
||||
E --> F["将其他档案 is_active=false"]
|

E --> G["将当前档案 is_active=true"]
|
||||
C --> |否| H["返回 400 达到上限"]

## 依赖分析
|
||||
- 路由层依赖处理器层,处理器层依赖服务层,服务层依赖仓储层,仓储层依赖数据库与模型。
|
||||
- 处理器层与服务层均依赖统一响应结构与请求/响应类型定义。
|
||||
- 档案模型与材质模型存在外键关联,查询时进行预加载以减少N+1问题。

||||
## 性能考虑
|
||||
- 预加载关联材质:仓储层在查询用户档案列表时预加载 Skin 与 Cape,避免多次查询。
|
||||
- 事务一致性:设置活跃状态采用数据库事务,确保原子性与一致性。
|
||||
- 唯一性约束:角色名在模型层定义唯一索引,查询时可快速判定冲突。
|
||||
- 响应结构:统一响应结构便于前端处理与日志记录。
|
||||
|
||||

|
||||
|
||||
## 故障排查指南
|
||||
- 400 参数错误
|
||||

|
||||
- 已达到档案数量上限(默认5个)
|
||||
- 401 未授权
|
||||
- 缺少或无效的认证令牌
|
||||
- 403 权限不足

||||
- 操作他人档案(如更新/删除/设置活跃)
|
||||
- 404 资源不存在
|
||||
- 档案UUID不存在
|
||||
- 500 服务器错误
|
||||

## 结论
|
||||
- 创建档案接口严格遵循请求体校验与业务规则,确保角色名唯一与数量上限控制。
|
||||
- 活跃状态切换通过事务保障一致性,避免并发场景下的状态不一致。
|
||||
- 档案列表接口提供完整档案信息与关联材质,满足前端展示需求。
|
||||
- 建议在生产环境中将上限值从硬编码迁移到系统配置中心,以便动态调整。
