+# Zulip Gateway Module
+
+## 📋 模块概述
+
+Zulip网关模块，负责提供Zulip相关功能的HTTP API接口。
+
+## 🏗️ 架构定位
+
+- **层级**: Gateway层（网关层）
+- **职责**: HTTP协议处理、API接口暴露、请求验证
+- **依赖**: Business层的ZulipModule
+
+## 📁 文件结构
+
+```

+└── README.md                             # 本文档
+```
+
+## 🎯 主要功能
+
+### 1. 动态配置管理 (DynamicConfigController)
+- 获取当前配置
+- 同步远程配置
+- 配置状态查询
+- 备份管理
+
+### 2. WebSocket文档 (WebSocketDocsController)
+- 提供WebSocket API使用文档
+- 消息格式示例
+- 连接示例代码
+
+### 3. WebSocket OpenAPI (WebSocketOpenApiController)
+- 在Swagger中展示WebSocket接口
+- 提供测试工具推荐
+- 架构信息展示
+
+### 4. WebSocket测试工具 (WebSocketTestController)
+- 交互式WebSocket测试页面
+- 支持连接、认证、消息发送测试
+- API调用监控功能
+
+### 5. Zulip账号管理 (ZulipAccountsController)
+- Zulip账号关联CRUD操作
+- 账号验证和统计
+- 批量管理功能
+
+## 🔗 依赖关系
+
+```
+ZulipGatewayModule
+  ├─ imports: ZulipModule (Business层)
+  ├─ imports: AuthModule (Business层)
+  └─ controllers: [所有Controller]
+```
+
+## 📝 使用示例
+
+### 在AppModule中导入
+
+```typescript
+import { ZulipGatewayModule } from './gateway/zulip/zulip.gateway.module';
+
+@Module({
+  imports: [
+    // ... 其他模块
+    ZulipGatewayModule,
+  ],
+})
+export class AppModule {}
+```
+
+## 🚨 架构规范
+
+### Gateway层职责
+- ✅ HTTP协议处理
+- ✅ 请求参数验证（DTO）
+- ✅ 调用Business层服务
+- ✅ 响应格式转换
+- ✅ 错误处理和转换
+
+### Gateway层禁止
+- ❌ 包含业务逻辑
+- ❌ 直接访问数据库
+- ❌ 直接调用Core层（应通过Business层）
+- ❌ 包含复杂的业务规则

+ * WebSocket API 文档控制器
+ * 
+ * 功能描述：
+ * - 提供 WebSocket API 的详细文档
+ * - 展示消息格式和事件类型
+ * - 提供连接示例和测试工具
+ * 
+ * 架构定位：
+ * - 层级：Gateway层（网关层）
+ * - 职责：HTTP协议处理、文档接口暴露
+ * - 依赖：无业务逻辑依赖，纯文档展示
+ * 
+ * 职责分离：
+ * - API文档：提供完整的WebSocket API使用说明
+ * - 示例代码：提供各种编程语言的连接示例
+ * - 调试支持：提供消息格式验证和测试工具
+ * - 开发指导：提供最佳实践和故障排除指南
+ * 
+ * 最近修改：
+ * - 2026-01-14: 架构优化 - 从Business层迁移到Gateway层，符合四层架构规范 (修改者: moyin)

+/**
+ * Zulip账号关联管理控制器
+ * 
+ * 功能描述：
+ * - 提供Zulip账号关联管理的REST API接口
+ * - 支持CRUD操作和批量管理
+ * - 提供账号验证和统计功能
+ * - 集成性能监控和结构化日志记录
+ * - 实现统一的错误处理和响应格式
+ * 
+ * 架构定位：
+ * - 层级：Gateway层（网关层）
+ * - 职责：HTTP协议处理、API接口暴露
+ * - 依赖：调用Business层的ZulipAccountsBusinessService
+ * 
+ * 职责分离：
+ * - API接口：提供RESTful风格的HTTP接口
+ * - 参数验证：使用DTO进行请求参数验证
+ * - 业务调用：调用Service层处理业务逻辑
+ * - 响应格式：统一API响应格式和错误处理
+ * - 性能监控：记录接口调用耗时和性能指标
+ * - 日志记录：使用AppLoggerService记录结构化日志
+ * 
+ * 最近修改：
+ * - 2026-01-14: 架构优化 - 从Business层迁移到Gateway层，符合四层架构规范 (修改者: moyin)
+ * - 2026-01-14: 代码质量优化 - 移除未使用的requestLogger属性 (修改者: moyin)
+ * - 2026-01-14: 代码质量优化 - 移除未使用的导入 (修改者: moyin)
+ * - 2026-01-12: 性能优化 - 集成AppLoggerService和性能监控，优化错误处理
+ * - 2025-01-07: 初始创建 - 实现基础的CRUD和管理接口
