## 简介
|
|||
|
|
本项目是一个面向耳机品牌与型号管理的后台管理系统，包含前后端分离的完整实现：前端基于 Vue 3 + Element Plus，后端基于 Express + Sequelize（MySQL），通过 Docker Compose 进行容器化部署。系统提供品牌管理、型号管理、OTA 升级包管理、黑名单管理、定向升级、分享码日志以及用户认证等能力。
|
|||
|
|
|
|||
|
|
## 项目结构
|
|||
|
|
仓库采用前后端分层组织方式：
|
|||
|
|
- backend：Express 应用入口、路由、模型、配置、中间件、服务与工具模块
|
|||
|
|
- frontend：Vue 3 应用入口、路由、布局、视图、API 封装、样式与工具
|
|||
|
|
- docker-compose.yml：编排前端 Nginx 与后端 Node 服务
|
|||
|
|
- DEPLOY.md：部署与环境说明

## 核心组件
|
|||
|
|
- 应用入口
|
|||
|
|
- 后端：Express 应用初始化、全局中间件、健康检查、路由挂载、数据库同步与启动监听
|
|||
|
|
- 前端：Vue 应用创建、Element Plus 注册、路由挂载、加载遮罩处理
|
|||
|
|
- 路由层
|
|||
|
|
- 后端：按功能域拆分路由并统一汇总挂载
|
|||
|
|
- 前端：基于 vue-router 的页面路由与导航守卫（鉴权、超级管理员控制）
|
|||
|
|
- 数据模型
|
|||

|
|||
|
|
- 配置与基础设施
|
|||
|
|

## 架构总览
|
|||
|
|
系统采用经典的前后端分离架构，前端静态资源由 Nginx 托管并通过反向代理将 /api 转发到后端；后端以 Express 提供服务，使用 Sequelize 访问 MySQL。

|||

### 首页“今日新增”数据流
|
|||
|
|
首页展示当日新增的型号与 OTA 记录，调用仪表盘统计接口获取数据。
|
|||
|
|
|
|||
|
|
```mermaid
|
|||
|
|
sequenceDiagram
|
|||
|
|
participant V as "Home 视图"
|
|||
|
|
participant API as "Dashboard API"
|
|||
|
|
participant S as "后端路由/服务"
|
|||
|
|
participant DB as "数据库"
|
|||
|
|
V->>API : 请求今日统计数据
|
|||
|
|
API->>S : 进入业务逻辑
|
|||
|
|
S->>DB : 聚合当日新增型号/OTA
|
|||
|
|
DB-->>S : 返回统计结果
|
|||
|
|
S-->>API : 组装响应
|

### 数据模型与关系（简化）
|
|||
|
|
以下模型用于品牌与型号管理，字段注释清晰，便于理解数据结构。
|
|||
|
|
|
|||
|
|
```mermaid
|
|||
|
|

|
|||
|
|

### 布局与导航
|
|||
|
|
侧边栏支持折叠/展开、面包屑与用户菜单，结合路由元信息进行权限控制与高亮。
|
|||

## 依赖关系分析
|
|||
|
|
- 后端依赖
|
|||
|
|
- Express、Sequelize、MySQL、JSON Web Token、Multer、Axios、Zod、Winston、ioredis、AWS SDK（S3）等
|
|||
|
|
- 前端依赖
|
|||
|
|
- Vue 3、Element Plus、Vue Router、Axios、JSON Pretty 等
|
|||
|
|
- 运行时编排
|
|||
|
|
- Docker Compose 编排前端 Nginx 与后端 Node 服务，端口映射与网络互通
|
|||
|
|
|
|||
|

## 性能与可扩展性
|
|||
|
|
- 数据库连接
|
|||
|
|
- 使用 Sequelize 连接 MySQL，建议在生产环境启用连接池与慢查询日志，合理设置超时与重试策略
|
|||
|
|
- 静态资源
|
|||
|
|
- 前端通过 Nginx 缓存静态资源，开启 Gzip/Brotli 压缩可提升首屏加载速度
|
|||
|
|
- 鉴权与限流
|
|||
|
|
- 建议在网关层增加速率限制与请求体大小限制（后端已有 bodyLimit 中间件）
|
|||
|
|
- 扩展点
|
|||
|
|
- 可按功能域继续拆分路由与服务，引入缓存层（Redis）与消息队列以提升吞吐
|
|||
|
|
|
|||

|
## 故障排查指南
|
|||
|
|
- 前端空白
|
|||
|
|
- 确认 dist 已上传且 Nginx 配置正确，查看浏览器控制台是否有 404 或跨域错误
|
|||
|
|
- API 请求失败
|
|||
|
|
- 检查后端容器状态与健康检查接口，查看后端日志定位数据库/Redis 连接问题
|
|||
|
|
- 后端构建失败
|
|||
