+title: "HTTP Routing"
+description: "HTTP REST API routing with WebSocket port sharing support"
+---
+
+`@esengine/server` includes a lightweight HTTP routing feature that can share the same port with WebSocket services, making it easy to implement REST APIs.
+
+## Quick Start
+
+### Inline Route Definition
+
+The simplest way is to define HTTP routes directly when creating the server:
+
+```typescript
+import { createServer } from '@esengine/server'
+
+const server = await createServer({
+    port: 3000,
+    http: {
+        '/api/health': (req, res) => {
+            res.json({ status: 'ok', time: Date.now() })
+        },
+        '/api/users': {
+            GET: (req, res) => {
+                res.json({ users: [] })
+            },
+            POST: async (req, res) => {
+                const body = req.body as { name: string }
+                res.status(201).json({ id: '1', name: body.name })
+            }
+        }
+    },
+    cors: true  // Enable CORS
+})
+
+await server.start()
+```
+
+### File-based Routing
+
+For larger projects, file-based routing is recommended. Create a `src/http` directory where each file corresponds to a route:
+
+```typescript
+// src/http/login.ts
+import { defineHttp } from '@esengine/server'
+
+interface LoginBody {
+    username: string
+    password: string
+}
+
+export default defineHttp<LoginBody>({
+    method: 'POST',
+    handler(req, res) {
+        const { username, password } = req.body as LoginBody
+
+        // Validate user...
+        if (username === 'admin' && password === '123456') {
+            res.json({ token: 'jwt-token-here', userId: 'user-1' })
+        } else {
+            res.error(401, 'Invalid username or password')
+        }
+    }
+})
+```
+
+```typescript
+// server.ts
+import { createServer } from '@esengine/server'
+
+const server = await createServer({
+    port: 3000,
+    httpDir: './src/http',   // HTTP routes directory
+    httpPrefix: '/api',       // Route prefix
+    cors: true
+})
+
+await server.start()
+// Route: POST /api/login
+```
+
+## defineHttp Definition
+
+`defineHttp` is used to define type-safe HTTP handlers:
+
+```typescript
+import { defineHttp } from '@esengine/server'
+
+interface CreateUserBody {
+    username: string
+    email: string
+    password: string
+}
+
+export default defineHttp<CreateUserBody>({
+    // HTTP method (default POST)
+    method: 'POST',
+
+    // Handler function
+    handler(req, res) {
+        const body = req.body as CreateUserBody
+        // Handle request...
+        res.status(201).json({ id: 'new-user-id' })
+    }
+})
+```
+
+### Supported HTTP Methods
+
+```typescript
+type HttpMethod = 'GET' | 'POST' | 'PUT' | 'DELETE' | 'PATCH' | 'OPTIONS'
+```
+
+## HttpRequest Object
+
+The HTTP request object contains the following properties:
+
+```typescript
+interface HttpRequest {
+    /** Raw Node.js IncomingMessage */
+    raw: IncomingMessage
+
+    /** HTTP method */
+    method: string
+
+    /** Request path */
+    path: string
+
+    /** Query parameters */
+    query: Record<string, string>
+
+    /** Request headers */
+    headers: Record<string, string | string[] | undefined>
+
+    /** Parsed request body */
+    body: unknown
+
+    /** Client IP */
+    ip: string
+}
+```
+
+### Usage Examples
+
+```typescript
+export default defineHttp({
+    method: 'GET',
+    handler(req, res) {
+        // Get query parameters
+        const page = parseInt(req.query.page ?? '1')
+        const limit = parseInt(req.query.limit ?? '10')
+
+        // Get request headers
+        const authHeader = req.headers.authorization
+
+        // Get client IP
+        console.log('Request from:', req.ip)
+
+        res.json({ page, limit })
+    }
+})
+```
+
+### Body Parsing
+
+The request body is automatically parsed based on `Content-Type`:
+
+- `application/json` - Parsed as JSON object
+- `application/x-www-form-urlencoded` - Parsed as key-value object
+- Others - Kept as raw string
+
+```typescript
+export default defineHttp<{ name: string; age: number }>({
+    method: 'POST',
+    handler(req, res) {
+        // body is already parsed
+        const { name, age } = req.body as { name: string; age: number }
+        res.json({ received: { name, age } })
+    }
+})
+```
+
+## HttpResponse Object
+
+The HTTP response object provides a chainable API:
+
+```typescript
+interface HttpResponse {
+    /** Raw Node.js ServerResponse */
+    raw: ServerResponse
+
+    /** Set status code */
+    status(code: number): HttpResponse
+
+    /** Set response header */
+    header(name: string, value: string): HttpResponse
+
+    /** Send JSON response */
+    json(data: unknown): void
+
+    /** Send text response */
+    text(data: string): void
+
+    /** Send error response */
+    error(code: number, message: string): void
+}
+```
+
+### Usage Examples
+
+```typescript
+export default defineHttp({
+    method: 'POST',
+    handler(req, res) {
+        // Set status code and custom headers
+        res
+            .status(201)
+            .header('X-Custom-Header', 'value')
+            .json({ created: true })
+    }
+})
+```
+
+```typescript
+export default defineHttp({
+    method: 'GET',
+    handler(req, res) {
+        // Send error response
+        res.error(404, 'Resource not found')
+        // Equivalent to: res.status(404).json({ error: 'Resource not found' })
+    }
+})
+```
+
+```typescript
+export default defineHttp({
+    method: 'GET',
+    handler(req, res) {
+        // Send plain text
+        res.text('Hello, World!')
+    }
+})
+```
+
+## File Routing Conventions
+
+### Name Conversion
+
+File names are automatically converted to route paths:
+
+| File Path | Route Path (prefix=/api) |
+|-----------|-------------------------|
+| `login.ts` | `/api/login` |
+| `users/profile.ts` | `/api/users/profile` |
+| `users/[id].ts` | `/api/users/:id` |
+| `game/room/[roomId].ts` | `/api/game/room/:roomId` |
+
+### Dynamic Route Parameters
+
+Use `[param]` syntax to define dynamic parameters:
+
+```typescript
+// src/http/users/[id].ts
+import { defineHttp } from '@esengine/server'
+
+export default defineHttp({
+    method: 'GET',
+    handler(req, res) {
+        // Get parameter from path
+        // Note: current version requires manual path parsing
+        const id = req.path.split('/').pop()
+        res.json({ userId: id })
+    }
+})
+```
+
+### Skip Rules
+
+The following files are automatically skipped:
+
+- Files starting with `_` (e.g., `_helper.ts`)
+- `index.ts` / `index.js` files
+- Non `.ts` / `.js` / `.mts` / `.mjs` files
+
+### Directory Structure Example
+
+```
+src/
+└── http/
+    ├── _utils.ts        # Skipped (underscore prefix)
+    ├── index.ts         # Skipped (index file)
+    ├── health.ts        # GET /api/health
+    ├── login.ts         # POST /api/login
+    ├── register.ts      # POST /api/register
+    └── users/
+        ├── index.ts     # Skipped
+        ├── list.ts      # GET /api/users/list
+        └── [id].ts      # GET /api/users/:id
+```
+
+## CORS Configuration
+
+### Quick Enable
+
+```typescript
+const server = await createServer({
+    port: 3000,
+    cors: true  // Use default configuration
+})
+```
+
+### Custom Configuration
+
+```typescript
+const server = await createServer({
+    port: 3000,
+    cors: {
+        // Allowed origins
+        origin: ['http://localhost:5173', 'https://myapp.com'],
+        // Or use wildcard
+        // origin: '*',
+        // origin: true,  // Reflect request origin
+
+        // Allowed HTTP methods
+        methods: ['GET', 'POST', 'PUT', 'DELETE'],
+
+        // Allowed request headers
+        allowedHeaders: ['Content-Type', 'Authorization', 'X-Requested-With'],
+
+        // Allow credentials (cookies)
+        credentials: true,
+
+        // Preflight cache max age (seconds)
+        maxAge: 86400
+    }
+})
+```
+
+### CorsOptions Type
+
+```typescript
+interface CorsOptions {
+    /** Allowed origins: string, string array, true (reflect) or '*' */
+    origin?: string | string[] | boolean
+
+    /** Allowed HTTP methods */
+    methods?: string[]
+
+    /** Allowed request headers */
+    allowedHeaders?: string[]
+
+    /** Allow credentials */
+    credentials?: boolean
+
+    /** Preflight cache max age (seconds) */
+    maxAge?: number
+}
+```
+
+## Route Merging
+
+File routes and inline routes can be used together, with inline routes having higher priority:
+
+```typescript
+const server = await createServer({
+    port: 3000,
+    httpDir: './src/http',
+    httpPrefix: '/api',
+
+    // Inline routes merge with file routes
+    http: {
+        '/health': (req, res) => res.json({ status: 'ok' }),
+        '/api/special': (req, res) => res.json({ special: true })
+    }
+})
+```
+
+## Sharing Port with WebSocket
+
+HTTP routes automatically share the same port with WebSocket services:
+
+```typescript
+const server = await createServer({
+    port: 3000,
+    // WebSocket related config
+    apiDir: './src/api',
+    msgDir: './src/msg',
+
+    // HTTP related config
+    httpDir: './src/http',
+    httpPrefix: '/api',
+    cors: true
+})
+
+await server.start()
+
+// Same port 3000:
+// - WebSocket: ws://localhost:3000
+// - HTTP API:  http://localhost:3000/api/*
+```
+
+## Complete Examples
+
+### Game Server Login API
+
+```typescript
+// src/http/auth/login.ts
+import { defineHttp } from '@esengine/server'
+import { createJwtAuthProvider } from '@esengine/server/auth'
+
+interface LoginRequest {
+    username: string
+    password: string
+}
+
+interface LoginResponse {
+    token: string
+    userId: string
+    expiresAt: number
+}
+
+const jwtProvider = createJwtAuthProvider({
+    secret: process.env.JWT_SECRET!,
+    expiresIn: 3600
+})
+
+export default defineHttp<LoginRequest>({
+    method: 'POST',
+    async handler(req, res) {
+        const { username, password } = req.body as LoginRequest
+
+        // Validate user
+        const user = await db.users.findByUsername(username)
+        if (!user || !await verifyPassword(password, user.passwordHash)) {
+            res.error(401, 'Invalid username or password')
+            return
+        }
+
+        // Generate JWT
+        const token = jwtProvider.sign({
+            sub: user.id,
+            name: user.username,
+            roles: user.roles
+        })
+
+        const response: LoginResponse = {
+            token,
+            userId: user.id,
+            expiresAt: Date.now() + 3600 * 1000
+        }
+
+        res.json(response)
+    }
+})
+```
+
+### Game Data Query API
+
+```typescript
+// src/http/game/leaderboard.ts
+import { defineHttp } from '@esengine/server'
+
+export default defineHttp({
+    method: 'GET',
+    async handler(req, res) {
+        const limit = parseInt(req.query.limit ?? '10')
+        const offset = parseInt(req.query.offset ?? '0')
+
+        const players = await db.players.findMany({
+            sort: { score: 'desc' },
+            limit,
+            offset
+        })
+
+        res.json({
+            data: players,
+            pagination: { limit, offset }
+        })
+    }
+})
+```
+
+## Best Practices
+
+1. **Use defineHttp** - Get better type hints and code organization
+2. **Unified Error Handling** - Use `res.error()` to return consistent error format
+3. **Enable CORS** - Required for frontend-backend separation
+4. **Directory Organization** - Organize HTTP route files by functional modules
+5. **Validate Input** - Always validate `req.body` and `req.query` content
+6. **Status Code Standards** - Follow HTTP status code conventions (200, 201, 400, 401, 404, 500, etc.)

 Supports HTTP API sharing the same port with WebSocket, ideal for login, registration, and similar scenarios.
 
-### File-based Routing
-
-Create route files in the `httpDir` directory, automatically mapped to HTTP endpoints:
-
-```
-src/http/
-├── login.ts       → POST /api/login
-├── register.ts    → POST /api/register
-├── health.ts      → GET  /api/health (set method: 'GET')
-└── users/
-    └── [id].ts    → POST /api/users/:id (dynamic route)
-```
-
-### Define Routes
-
-Use `defineHttp` to define type-safe route handlers:
-
 ```typescript
-// src/http/login.ts
+const server = await createServer({
-import { defineHttp } from '@esengine/server'
+    port: 3000,
+    httpDir: './src/http',   // HTTP routes directory
+    httpPrefix: '/api',       // Route prefix
+    cors: true,
 
-interface LoginBody {
+    // Or inline definition
-    username: string
+    http: {
-    password: string
+        '/health': (req, res) => res.json({ status: 'ok' })
-}
-
-export default defineHttp<LoginBody>({
-    method: 'POST',  // Default POST, options: GET/PUT/DELETE/PATCH
-    handler(req, res) {
-        const { username, password } = req.body
-
-        // Validate credentials...
-        if (!isValid(username, password)) {
-            res.error(401, 'Invalid credentials')
-            return
-        }
-
-        // Generate token...
-        res.json({ token: '...', userId: '...' })
     }
 })
 ```
 
-### Request Object (HttpRequest)
+> For detailed documentation, see [HTTP Routing](/en/modules/network/http)
-
-```typescript
-interface HttpRequest {
-    raw: IncomingMessage     // Node.js raw request
-    method: string           // Request method
-    path: string             // Request path
-    query: Record<string, string>  // Query parameters
-    headers: Record<string, string | string[] | undefined>
-    body: unknown            // Parsed JSON body
-    ip: string               // Client IP
-}
-```
-
-### Response Object (HttpResponse)
-
-```typescript
-interface HttpResponse {
-    raw: ServerResponse      // Node.js raw response
-    status(code: number): HttpResponse   // Set status code (chainable)
-    header(name: string, value: string): HttpResponse  // Set header (chainable)
-    json(data: unknown): void            // Send JSON
-    text(data: string): void             // Send text
-    error(code: number, message: string): void  // Send error
-}
-```
-
-### Usage Example
-
-```typescript
-// Complete login server example
-import { createServer, defineHttp } from '@esengine/server'
-import { createJwtAuthProvider, withAuth } from '@esengine/server/auth'
-
-const jwtProvider = createJwtAuthProvider({
-    secret: process.env.JWT_SECRET!,
-    expiresIn: 3600 * 24,
-})
-
-const server = await createServer({
-    port: 8080,
-    httpDir: 'src/http',
-    httpPrefix: '/api',
-    cors: true,
-})
-
-// Wrap with auth (WebSocket connections validate token)
-const authServer = withAuth(server, {
-    provider: jwtProvider,
-    extractCredentials: (req) => {
-        const url = new URL(req.url, 'http://localhost')
-        return url.searchParams.get('token')
-    },
-})
-
-await authServer.start()
-// HTTP: http://localhost:8080/api/*
-// WebSocket: ws://localhost:8080?token=xxx
-```
-
-### Inline Routes
-
-Routes can also be defined directly in configuration (merged with file routes, inline takes priority):
-
-```typescript
-const server = await createServer({
-    port: 8080,
-    http: {
-        '/health': {
-            GET: (req, res) => res.json({ status: 'ok' }),
-        },
-        '/webhook': async (req, res) => {
-            // Accepts all methods
-            await handleWebhook(req.body)
-            res.json({ received: true })
-        },
-    },
-})
-```

+description: "HTTP REST API 路由功能，支持与 WebSocket 共用端口"
+---
+
+`@esengine/server` 内置了轻量级的 HTTP 路由功能，可以与 WebSocket 服务共用同一端口，方便实现 REST API。
+
+## 快速开始
+
+### 内联路由定义
+
+最简单的方式是在创建服务器时直接定义 HTTP 路由：
+
+```typescript
+import { createServer } from '@esengine/server'
+
+const server = await createServer({
+    port: 3000,
+    http: {
+        '/api/health': (req, res) => {
+            res.json({ status: 'ok', time: Date.now() })
+        },
+        '/api/users': {
+            GET: (req, res) => {
+                res.json({ users: [] })
+            },
+            POST: async (req, res) => {
+                const body = req.body as { name: string }
+                res.status(201).json({ id: '1', name: body.name })
+            }
+        }
+    },
+    cors: true  // 启用 CORS
+})
+
+await server.start()
+```
+
+### 文件路由
+
+对于较大的项目，推荐使用文件路由。创建 `src/http` 目录，每个文件对应一个路由：
+
+```typescript
+// src/http/login.ts
+import { defineHttp } from '@esengine/server'
+
+interface LoginBody {
+    username: string
+    password: string
+}
+
+export default defineHttp<LoginBody>({
+    method: 'POST',
+    handler(req, res) {
+        const { username, password } = req.body as LoginBody
+
+        // 验证用户...
+        if (username === 'admin' && password === '123456') {
+            res.json({ token: 'jwt-token-here', userId: 'user-1' })
+        } else {
+            res.error(401, '用户名或密码错误')
+        }
+    }
+})
+```
+
+```typescript
+// server.ts
+import { createServer } from '@esengine/server'
+
+const server = await createServer({
+    port: 3000,
+    httpDir: './src/http',   // HTTP 路由目录
+    httpPrefix: '/api',       // 路由前缀
+    cors: true
+})
+
+await server.start()
+// 路由: POST /api/login
+```
+
+## defineHttp 定义

+`defineHttp` 用于定义类型安全的 HTTP 处理器：
+
+```typescript
+import { defineHttp } from '@esengine/server'
+
+interface CreateUserBody {
+    username: string
+    email: string
+    password: string
+}
+
+export default defineHttp<CreateUserBody>({
+    // HTTP 方法（默认 POST）
+    method: 'POST',
+
+    // 处理函数
+    handler(req, res) {
+        const body = req.body as CreateUserBody
+        // 处理请求...
+        res.status(201).json({ id: 'new-user-id' })
+    }
+})
+```
+
+### 支持的 HTTP 方法
+
+```typescript
+type HttpMethod = 'GET' | 'POST' | 'PUT' | 'DELETE' | 'PATCH' | 'OPTIONS'
+```
+
+## HttpRequest 对象
+
+HTTP 请求对象包含以下属性：
+
+```typescript
+interface HttpRequest {
+    /** 原始 Node.js IncomingMessage */
+    raw: IncomingMessage
+
+    /** HTTP 方法 */
+    method: string
+
+    /** 请求路径 */
+    path: string
+
+    /** 查询参数 */
+    query: Record<string, string>
+
+    /** 请求头 */
+    headers: Record<string, string | string[] | undefined>
+
+    /** 解析后的请求体 */
+    body: unknown
+
+    /** 客户端 IP */
+    ip: string
+}
+```
+
+### 使用示例
+
+```typescript
+export default defineHttp({
+    method: 'GET',
+    handler(req, res) {
+        // 获取查询参数
+        const page = parseInt(req.query.page ?? '1')
+        const limit = parseInt(req.query.limit ?? '10')
+
+        // 获取请求头
+        const authHeader = req.headers.authorization
+
+        // 获取客户端 IP
+        console.log('Request from:', req.ip)
+
+        res.json({ page, limit })
+    }
+})
+```
+
+### 请求体解析
+
+请求体会根据 `Content-Type` 自动解析：
+
+- `application/json` - 解析为 JSON 对象
+- `application/x-www-form-urlencoded` - 解析为键值对对象
+- 其他 - 保持原始字符串
+
+```typescript
+export default defineHttp<{ name: string; age: number }>({
+    method: 'POST',
+    handler(req, res) {
+        // body 已自动解析
+        const { name, age } = req.body as { name: string; age: number }
+        res.json({ received: { name, age } })
+    }
+})
+```
+
+## HttpResponse 对象
+
+HTTP 响应对象提供链式 API：
+
+```typescript
+interface HttpResponse {
+    /** 原始 Node.js ServerResponse */
+    raw: ServerResponse
+
+    /** 设置状态码 */
+    status(code: number): HttpResponse
+
+    /** 设置响应头 */
+    header(name: string, value: string): HttpResponse
+
+    /** 发送 JSON 响应 */
+    json(data: unknown): void
+
+    /** 发送文本响应 */
+    text(data: string): void
+
+    /** 发送错误响应 */
+    error(code: number, message: string): void
+}
+```
+
+### 使用示例
+
+```typescript
+export default defineHttp({
+    method: 'POST',
+    handler(req, res) {
+        // 设置状态码和自定义头
+        res
+            .status(201)
+            .header('X-Custom-Header', 'value')
+            .json({ created: true })
+    }
+})
+```
+
+```typescript
+export default defineHttp({
+    method: 'GET',
+    handler(req, res) {
+        // 发送错误响应
+        res.error(404, '资源不存在')
+        // 等价于: res.status(404).json({ error: '资源不存在' })
+    }
+})
+```
+
+```typescript
+export default defineHttp({
+    method: 'GET',
+    handler(req, res) {
+        // 发送纯文本
+        res.text('Hello, World!')
+    }
+})
+```
+
+## 文件路由规范
+
+### 命名转换
+
+文件名会自动转换为路由路径：
+
+| 文件路径 | 路由路径（prefix=/api） |
+|---------|----------------------|
+| `login.ts` | `/api/login` |
+| `users/profile.ts` | `/api/users/profile` |
+| `users/[id].ts` | `/api/users/:id` |
+| `game/room/[roomId].ts` | `/api/game/room/:roomId` |
+
+### 动态路由参数
+
+使用 `[param]` 语法定义动态参数：
+
+```typescript
+// src/http/users/[id].ts
+import { defineHttp } from '@esengine/server'
+
+export default defineHttp({
+    method: 'GET',
+    handler(req, res) {
+        // 从路径获取参数
+        // 注意：当前版本需要手动解析 path
+        const id = req.path.split('/').pop()
+        res.json({ userId: id })
+    }
+})
+```
+
+### 跳过规则
+
+以下文件会被自动跳过：
+
+- 以 `_` 开头的文件（如 `_helper.ts`）
+- `index.ts` / `index.js` 文件
+- 非 `.ts` / `.js` / `.mts` / `.mjs` 文件
+
+### 目录结构示例
+
+```
+src/
+└── http/
+    ├── _utils.ts        # 跳过（下划线开头）
+    ├── index.ts         # 跳过（index 文件）
+    ├── health.ts        # GET /api/health
+    ├── login.ts         # POST /api/login
+    ├── register.ts      # POST /api/register
+    └── users/
+        ├── index.ts     # 跳过
+        ├── list.ts      # GET /api/users/list
+        └── [id].ts      # GET /api/users/:id
+```
+
+## CORS 配置
+
+### 快速启用
+
+```typescript
+const server = await createServer({
+    port: 3000,
+    cors: true  // 使用默认配置
+})
+```
+
+### 自定义配置
+
+```typescript
+const server = await createServer({
+    port: 3000,
+    cors: {
+        // 允许的来源
+        origin: ['http://localhost:5173', 'https://myapp.com'],
+        // 或使用通配符
+        // origin: '*',
+        // origin: true,  // 反射请求来源
+
+        // 允许的 HTTP 方法
+        methods: ['GET', 'POST', 'PUT', 'DELETE'],
+
+        // 允许的请求头
+        allowedHeaders: ['Content-Type', 'Authorization', 'X-Requested-With'],
+
+        // 是否允许携带凭证（cookies）
+        credentials: true,
+
+        // 预检请求缓存时间（秒）
+        maxAge: 86400
+    }
+})
+```
+
+### CorsOptions 类型
+
+```typescript
+interface CorsOptions {
+    /** 允许的来源：字符串、字符串数组、true（反射）或 '*' */
+    origin?: string | string[] | boolean
+
+    /** 允许的 HTTP 方法 */
+    methods?: string[]
+
+    /** 允许的请求头 */
+    allowedHeaders?: string[]
+
+    /** 是否允许携带凭证 */
+    credentials?: boolean
+
+    /** 预检请求缓存时间（秒） */
+    maxAge?: number
+}
+```
+
+## 路由合并
+
+文件路由和内联路由可以同时使用，内联路由优先级更高：
+
+```typescript
+const server = await createServer({
+    port: 3000,
+    httpDir: './src/http',
+    httpPrefix: '/api',
+
+    // 内联路由会与文件路由合并
+    http: {
+        '/health': (req, res) => res.json({ status: 'ok' }),
+        '/api/special': (req, res) => res.json({ special: true })
+    }
+})
+```
+
+## 与 WebSocket 共用端口
+
+HTTP 路由与 WebSocket 服务自动共用同一端口：
+
+```typescript
+const server = await createServer({
+    port: 3000,
+    // WebSocket 相关配置
+    apiDir: './src/api',
+    msgDir: './src/msg',
+
+    // HTTP 相关配置
+    httpDir: './src/http',
+    httpPrefix: '/api',
+    cors: true
+})
+
+await server.start()
+
+// 同一端口 3000：
+// - WebSocket: ws://localhost:3000
+// - HTTP API:  http://localhost:3000/api/*
+```
+
+## 完整示例
+
+### 游戏服务器登录 API
+
+```typescript
+// src/http/auth/login.ts
+import { defineHttp } from '@esengine/server'
+import { createJwtAuthProvider } from '@esengine/server/auth'
+
+interface LoginRequest {
+    username: string
+    password: string
+}
+
+interface LoginResponse {
+    token: string
+    userId: string
+    expiresAt: number
+}
+
+const jwtProvider = createJwtAuthProvider({
+    secret: process.env.JWT_SECRET!,
+    expiresIn: 3600
+})
+
+export default defineHttp<LoginRequest>({
+    method: 'POST',
+    async handler(req, res) {
+        const { username, password } = req.body as LoginRequest
+
+        // 验证用户
+        const user = await db.users.findByUsername(username)
+        if (!user || !await verifyPassword(password, user.passwordHash)) {
+            res.error(401, '用户名或密码错误')
+            return
+        }
+
+        // 生成 JWT
+        const token = jwtProvider.sign({
+            sub: user.id,
+            name: user.username,
+            roles: user.roles
+        })
+
+        const response: LoginResponse = {
+            token,
+            userId: user.id,
+            expiresAt: Date.now() + 3600 * 1000
+        }
+
+        res.json(response)
+    }
+})
+```
+
+### 游戏数据查询 API
+
+```typescript
+// src/http/game/leaderboard.ts
+import { defineHttp } from '@esengine/server'
+
+export default defineHttp({
+    method: 'GET',
+    async handler(req, res) {
+        const limit = parseInt(req.query.limit ?? '10')
+        const offset = parseInt(req.query.offset ?? '0')
+
+        const players = await db.players.findMany({
+            sort: { score: 'desc' },
+            limit,
+            offset
+        })
+
+        res.json({
+            data: players,
+            pagination: { limit, offset }
+        })
+    }
+})
+```
+
+## 最佳实践
+
+1. **使用 defineHttp** - 获得更好的类型提示和代码组织
+2. **统一错误处理** - 使用 `res.error()` 返回一致的错误格式
+3. **启用 CORS** - 前后端分离时必须配置
+4. **目录组织** - 按功能模块组织 HTTP 路由文件
+5. **验证输入** - 始终验证 `req.body` 和 `req.query` 的内容
+6. **状态码规范** - 遵循 HTTP 状态码规范（200、201、400、401、404、500 等）

-### 文件路由
+```typescript
-
+const server = await createServer({
-在 `httpDir` 目录下创建路由文件，自动映射为 HTTP 端点：
+    port: 3000,
+    httpDir: './src/http',   // HTTP 路由目录
+    httpPrefix: '/api',       // 路由前缀
+    cors: true,
 
+    // 或内联定义
+    http: {
+        '/health': (req, res) => res.json({ status: 'ok' })
+    }
+})
 ```
-src/http/
-├── login.ts       → POST /api/login
-├── register.ts    → POST /api/register
-├── health.ts      → GET  /api/health (需设置 method: 'GET')
-└── users/
-    └── [id].ts    → POST /api/users/:id (动态路由)
-```
-
-### 定义路由
-
-使用 `defineHttp` 定义类型安全的路由处理器：
 
 ```typescript
 // src/http/login.ts
 import { defineHttp } from '@esengine/server'
 
-interface LoginBody {
+export default defineHttp<{ username: string; password: string }>({
-    username: string
+    method: 'POST',
-    password: string
-}
-
-export default defineHttp<LoginBody>({
-    method: 'POST',  // 默认 POST，可选 GET/PUT/DELETE/PATCH
     handler(req, res) {
         const { username, password } = req.body
-
+        // 验证并返回 token...
-        // 验证凭证...
+        res.json({ token: '...' })
-        if (!isValid(username, password)) {
-            res.error(401, 'Invalid credentials')
-            return
-        }
-
-        // 生成 token...
-        res.json({ token: '...', userId: '...' })
     }
 })
 ```
 
-### 请求对象 (HttpRequest)
+> 详细文档请参考 [HTTP 路由](/modules/network/http)
-
-```typescript
-interface HttpRequest {
-    raw: IncomingMessage     // Node.js 原始请求
-    method: string           // 请求方法
-    path: string             // 请求路径
-    query: Record<string, string>  // 查询参数
-    headers: Record<string, string | string[] | undefined>
-    body: unknown            // 解析后的 JSON 请求体
-    ip: string               // 客户端 IP
-}
-```
-
-### 响应对象 (HttpResponse)
-
-```typescript
-interface HttpResponse {
-    raw: ServerResponse      // Node.js 原始响应
-    status(code: number): HttpResponse   // 设置状态码（链式）
-    header(name: string, value: string): HttpResponse  // 设置头（链式）
-    json(data: unknown): void            // 发送 JSON
-    text(data: string): void             // 发送文本
-    error(code: number, message: string): void  // 发送错误
-}
-```
-
-### 使用示例
-
-```typescript
-// 完整的登录服务器示例
-import { createServer, defineHttp } from '@esengine/server'
-import { createJwtAuthProvider, withAuth } from '@esengine/server/auth'
-
-const jwtProvider = createJwtAuthProvider({
-    secret: process.env.JWT_SECRET!,
-    expiresIn: 3600 * 24,
-})
-
-const server = await createServer({
-    port: 8080,
-    httpDir: 'src/http',
-    httpPrefix: '/api',
-    cors: true,
-})
-
-// 包装认证（WebSocket 连接验证 token）
-const authServer = withAuth(server, {
-    provider: jwtProvider,
-    extractCredentials: (req) => {
-        const url = new URL(req.url, 'http://localhost')
-        return url.searchParams.get('token')
-    },
-})
-
-await authServer.start()
-// HTTP: http://localhost:8080/api/*
-// WebSocket: ws://localhost:8080?token=xxx
-```
-
-### 内联路由
-
-也可以直接在配置中定义路由（与文件路由合并，内联优先）：
-
-```typescript
-const server = await createServer({
-    port: 8080,
-    http: {
-        '/health': {
-            GET: (req, res) => res.json({ status: 'ok' }),
-        },
-        '/webhook': async (req, res) => {
-            // 接受所有方法
-            await handleWebhook(req.body)
-            res.json({ received: true })
-        },
-    },
-})
-```
