+# Ktor Server Demo 接口文档 (RESTful & kotlinx-rpc)
+
+本文档详细描述了 **Ktor Server Demo** 后端服务的 **kotlinx-rpc 远程过程调用接口** 与 **RESTful / WebSocket 接口**
+规范，旨在帮助前端开发者、Kotlin 多平台（KMP）客户端开发者以及联调人员快速集成与测试。
+
+---
+
+## 1. kotlinx-rpc 远程过程调用规范 (推荐)
+
+服务端基于 JetBrains 官方 **kotlinx-rpc** (kRPC 协议) 提供强类型、跨平台、端到端的 RPC 通信支持，基于 WebSocket 传输并支持
+JSON 序列化。
+
+### 1.1 RPC 服务端点
+
+- **RPC 挂载端点**: `ws://localhost:8080/rpc`
+- **传输协议**: `kRPC` (基于 Ktor WebSockets)
+- **序列化格式**: JSON (`kotlinx.rpc.krpc.serialization.json`)
+
+### 1.2 客户端接入方式 (Kotlin / KMP)
+
+在客户端的 `build.gradle.kts` 中引入依赖：
+
+```kotlin
+plugins {
+    id("org.jetbrains.kotlinx.rpc.plugin") version "0.10.4"
+    id("org.jetbrains.kotlin.plugin.serialization") version "2.4.0"
+}
+
+dependencies {
+    implementation("org.jetbrains.kotlinx:kotlinx-rpc-krpc-ktor-client:0.10.4")
+    implementation("org.jetbrains.kotlinx:kotlinx-rpc-krpc-serialization-json:0.10.4")
+    implementation("io.ktor:ktor-client-cio:3.6.0")
+    implementation("io.ktor:ktor-client-websockets:3.6.0")
+}
+```
+
+客户端建立 RPC 连接与调用示例：
+
+```kotlin
+import io.ktor.client.*
+import io.ktor.client.engine.cio.*
+import io.ktor.http.*
+import kotlinx.rpc.krpc.ktor.client.installKrpc
+import kotlinx.rpc.krpc.ktor.client.rpc
+import kotlinx.rpc.krpc.serialization.json.json
+import kotlinx.rpc.withService
+
+val httpClient = HttpClient(CIO) {
+    installKrpc {
+        serialization {
+            json()
+        }
+    }
+}
+
+// 建立连接到 RPC 端点
+val rpcClient = httpClient.rpc {
+    url {
+        protocol = URLProtocol.WS
+        host = "localhost"
+        port = 8080
+        path("/rpc")
+    }
+}
+
+// 1. 获取认证服务代理
+val authService = rpcClient.withService<AuthRpcService>()
+val loginResult = authService.login(LoginVO(username = "test", password = "123456"))
+
+// 2. 获取测试服务代理
+val testService = rpcClient.withService<TestRpcService>()
+println(testService.hello())
+
+// 3. 获取实时流式服务代理 (支持 Flow 双向流)
+val streamService = rpcClient.withService<StreamRpcService>()
+val echoResult = streamService.echo("hello")
+```
+
+---
+
+### 1.3 RPC 契约定义清单
+
+#### 1.3.1 认证服务 (`AuthRpcService`)
+
+定义在包 `io.github.sor2171.backend.rpc.AuthRpcService`：
+
+```kotlin
+@Rpc
+interface AuthRpcService {
+    // 用户名/邮箱与密码登录
+    suspend fun login(loginVO: LoginVO): ApiResponse<AuthorizeVO?>
+
+    // 发送邮箱验证码 (支持 REGISTER 或 RESET)
+    suspend fun askCode(email: String, type: EmailType, clientIp: String = "127.0.0.1"): ApiResponse<String?>
+
+    // 邮箱与验证码注册新账号
+    suspend fun register(registerVO: EmailRegisterVO): ApiResponse<String?>
+
+    // 验证码重置密码
+    suspend fun resetPassword(resetVO: PasswordResetVO): ApiResponse<String?>
+
+    // 注销登录并拉黑 Token
+    suspend fun logout(token: String): ApiResponse<String?>
+
+    // 续签刷新 Token
+    suspend fun relogin(token: String): ApiResponse<ReloginVO?>
+}
+```
+
+#### 1.3.2 辅助与测试服务 (`TestRpcService`)
+
+定义在包 `io.github.sor2171.backend.rpc.TestRpcService`：
+
+```kotlin
+@Rpc
+interface TestRpcService {
+    // 连通性测试，返回 "Hello Kotlin Ktor RPC!"
+    suspend fun hello(): String
+
+    // 签发一次性 WebSocket 握手 Token
+    suspend fun getWsToken(handlerName: String = "ExampleHandler"): ApiResponse<String>
+}
+```
+
+#### 1.3.3 实时与双向流通信服务 (`StreamRpcService`)
+
+定义在包 `io.github.sor2171.backend.rpc.StreamRpcService`，利用 Kotlin 协程 `Flow` 进行全双工流式传输：
+
+```kotlin
+@Rpc
+interface StreamRpcService {
+    // 单次回显调用
+    suspend fun echo(message: String): String
+
+    // 响应式双向流传输 (Client Flow -> Server Flow)
+    fun echoStream(messages: Flow<String>): Flow<String>
+}
+```
+
+---
+
+## 2. 全局设计规范 (RESTful API)
+
+### 2.1 服务基础信息
+
+- **服务基础地址 (Base URL)**: `http://localhost:8080`
+- **WebSocket 基础地址 (WS URL)**: `ws://localhost:8080`
+- **字符编码**: `UTF-8`
+- **数据格式**: 请求体与响应体默认采用 `application/json`；部分接口（如登录）额外兼容 `application/x-www-form-urlencoded`。
+
+### 2.2 跨域策略 (CORS)
+
+服务已配置全局跨域支持：
+
+- 支持任意 Host 源请求 (`anyHost()`)
+- 允许携带凭证 (`Access-Control-Allow-Credentials: true`)
+- 允许的请求方法：`GET`, `POST`, `PUT`, `DELETE`, `PATCH`, `OPTIONS`
+- 允许的请求头：`Content-Type`, `Authorization`
+
+### 2.3 身份认证机制 (Authentication)
+
+- 基于 **JWT (JSON Web Token)** 进行无状态认证（HMAC256 签名）。
+- 对于受保护的接口，客户端须在请求头中携带：
+  ```http
+  Authorization: Bearer <your_jwt_token>
+  ```
+- **Token 结构说明**：包含用户 ID (`id`)、用户名 (`username`)、角色权限 (`authorities`)、唯一标识 (`jti`) 及签发/过期时间戳。默认有效期为
+  168 小时（7 天）。
+- **Token 黑名单机制**：用户调用注销登录（Logout）后，Token 的唯一标识（`jti`）将被置入 Redis 黑名单，直至该 Token 自然过期。黑名单中的
+  Token 即使签名有效也无法通过鉴权。
+
+### 2.4 全局限流与防护 (Flow Limit)
+
+- 服务端基于客户端 IP 实现全局访问频率保护：
+    - 默认限频规则： **3 秒内请求次数超过 1000 次** 将触发防护。
+    - 触发防护后封禁时长： **60 秒**。
+    - 被限流时的响应：HTTP 状态码 `403 Forbidden`，返回信息为 `"Too many requests"`。
+- 发送邮件验证码接口具有独立的频控逻辑： **同一 IP 60 秒内仅允许请求一次**。
+
+### 2.5 统一响应结构 (ApiResponse)
+
+所有 RESTful 接口均遵循统一的包装结构（除连通性测试等纯文本接口外）：
+
+```json
+{
+  "code": 200,
+  "data": null,
+  "message": "Success"
+}
+```
+
+#### 字段说明
+
+| 字段名    | 类型     | 说明                                                                      |
+|:----------|:---------|:--------------------------------------------------------------------------|
+| `code`    | `Int`    | 业务状态码，通常与 HTTP 状态码保持一致（如 200、400、401、403、404、500） |
+| `data`    | `Any?`   | 业务数据对象，成功时返回对应实体，无数据或失败时通常为 `null`             |
+| `message` | `String` | 提示消息（如 `"Success"` 或具体错误原因）                                 |
+
+---
+
+## 3. RESTful 接口列表概览
+
+> **说明**：用户认证相关路由同时支持 `/api/v1/auth/...` 与兼容前缀 `/api/auth/...`。
+
+| 分类        | 方法   | 路径                    | 认证方式       | 说明                                   |
+|:------------|:-------|:------------------------|:---------------|:---------------------------------------|
+| **认证**    | `POST` | `/api/v1/auth/login`    | 公开           | 用户名/邮箱与密码登录，返回 JWT        |
+| **认证**    | `GET`  | `/api/v1/auth/ask-code` | 公开           | 发送邮箱验证码（注册/重置密码）        |
+| **认证**    | `POST` | `/api/v1/auth/register` | 公开           | 邮箱验证码注册新账号                   |
+| **认证**    | `POST` | `/api/v1/auth/reset`    | 公开           | 邮箱验证码重置登录密码                 |
+| **认证**    | `GET`  | `/api/v1/auth/logout`   | `Bearer Token` | 注销登录并拉黑当前 Token               |
+| **认证**    | `GET`  | `/api/v1/auth/relogin`  | `Bearer Token` | 续签刷新 Token                         |
+| **测试**    | `GET`  | `/api/test/hello`       | 公开           | 服务连通性测试                         |
+| **测试**    | `GET`  | `/api/test/wstoken`     | 公开           | 签发一次性 WebSocket 握手 Token        |
+| **WS 通信** | `WS`   | `/ws/test`              | 公开           | WebSocket 基础连通测试通道             |
