  level: 'info',
  format: ':method :url :status :response-time ms'
}))
/* ================= 中间件 ================= */

  origin: [
    'http://localhost:3000',
    'http://localhost:5174',
    'http://localhost:5173',
    'http://localhost:5175'
  ],
  credentials: true
}))

// 统一返回中间件
app.use(response)

/* ================= 路由 ================= */

// 公共接口
app.use('/api/public',decryptMiddleware,publicRoutes)
// 私有接口（JWT 验证）

// 按文件夹自动挂载路由
mount(app, path.join(process.cwd(), '/apps/http-server/routes'), true)

/* ================= Swagger ================= */

if (process.env.NODE_ENV !== 'production') {
  const expressSwagger = require('express-swagger-generator')(app)
  const swaggerOptions = require('../../config/swagger')
  expressSwagger(swaggerOptions)
  console.log(`Swagger 文档已生成: ${process.env.HTTP_URL}:${process.env.HTTP_PORT}${swaggerOptions.route.url}`)
}


/* ================= 404 ================= */

app.use((req, res) => {

    if (req.method === 'GET' && accept.includes('text/html')) {
        res.status(404).send('Not Found')
    }  else {
        res.sendResult({ data: null, code: 404, message: 'Not Found' })
    }
})
  
/* ================= Error Handler ================= */

app.use((err, req, res, next) => {
  if (err.name === 'UnauthorizedError') {
    return res.sendResult({data: null, code: 401, message: 'token无效或已过期'})

const wss = new WebSocket.Server({ port: process.env.WS_PORT })

wss.on('connection', (ws, req) => {
    ws.on('message', async msg => {
        const text = msg.toString()
        const data = aes.de(text)
        socketRouter(ws, data)
    })

        try {
          onlineUsers.delete(uid)
          await cache.del(cache.buildKey('ws', 'user', ws.id))
          logger.info(`WS closed uid=${uid} code=${code} reason=${reason?.toString() || ''}`)
        } catch (err) {
          logger.error(`WS close cleanup error uid=${uid}: ${err.message}`)
        } finally {
          ws.id = null
          ws.user = null
          ws.token = null
        }
      })
      
})

## 九、PM2

### ecosystem.config.js

```js
module.exports = {
  apps: [
    { name: 'http', script: 'apps/http-server/app.js', instances: 'max' },
    { name: 'ws', script: 'apps/ws-server/ws.js', instances: 4 }
  ]
}
```

---

## 十、启动方式

```bash
npm install
npm run dev
npm run serve
node apps/http-server/app.js
node apps/ws-server/ws.js
# 或
pm2 start ecosystem.config.js
```

---

## ✅ 至此：

* 所有模块 **已补齐**
* 可直接启动
* 支撑百万用户架构

如果你下一步要：

* WS 房间 / 广播
* 压测脚本
* 订单 / 支付模块

👉 直接说，我在这个项目上继续补。

---

# README.md

---

## 🧱 技术栈

---

## ⚙️ 环境要求

* Node.js >= 18
* MySQL >= 5.7
* Redis >= 6.x
* PM2（生产环境推荐）

---

## 🔧 环境变量配置（.env）

```env
NODE_ENV=development
HTTP_PORT=3000
WS_PORT=4000

DB_HOST=127.0.0.1
DB_PORT=3306
DB_USER=root
DB_PASS=123456
DB_NAME=demo

JWT_SECRET=jwt_secret_key

REDIS_HOST=127.0.0.1
REDIS_PORT=6379
```

---

## 🚀 启动方式

### 1️⃣ 安装依赖

```bash
npm install
```

### 2️⃣ 开发模式启动

```bash
node apps/http-server/app.js
node apps/ws-server/ws.js
```

### 3️⃣ 生产模式（推荐）

```bash
pm2 start ecosystem.config.js
```

---

## 🔐 鉴权说明

* HTTP 私有接口：

  * 使用 JWT + Redis Session 校验
  * Header：`Authorization: Bearer <token>`

* WebSocket：

  * 连接参数：`?token=xxx`
  * 连接时校验 JWT

---

## 📤 文件上传

* 上传接口：`POST /api/public/upload`
* 表单字段：`file`
* 返回：

```json
{
  "code": 0,
  "msg": "ok",
  "data": {
    "id": "文件ID",
    "mimetype": "image/png"
  }
}
```

* 获取文件：

```http
GET /api/public/getFiles?id=文件ID
```

---

## 📊 并发与扩展能力

| 能力      | 说明            |
| ------- | ------------- |
| HTTP 并发 | PM2 多进程 + 无状态 |
| WS 在线   | 单机 5~10 万连接   |
| 横向扩展    | Redis 统一状态    |
| 用户规模    | 百万级           |

---

## 🧠 设计原则

* WebSocket 与 HTTP **完全解耦**
* Redis 作为 **强一致核心组件**
* JWT 只做身份声明，会话态在 Redis
* 所有模块 **可替换、可扩展**

---

## 📌 后续可扩展方向

* 用户注册 / 登录 / 封禁体系
* WS 房间 / 广播 / IM 系统
* 订单 / 支付模块
* Nginx + CDN 静态资源
* Redis Cluster / MySQL 分库分表

---

## ✅ 适用场景

* IM / 聊天系统
* 社交 / 实时互动
* 游戏后端
* 直播 / 弹幕系统
