+# HTTP Server Capability Specification
+
+## Purpose
+该规范描述了本项目中 HTTP 服务器的功能和设计目标。它确保了 API 的可靠性和可维护性。
+## Requirements
+### Requirement: API 服务器框架已更新
+
+- **说明**: 底层 Web 框架从 Gin 迁移到 Echo。所有现有的 API 端点 **MUST** 保持功能齐全和向后兼容。
+- **理由**: 为了提高路由灵活性并使技术栈现代化。这是一次技术重构，不会改变任何外部 API 行为。
+- **影响**: 高。影响核心请求处理、路由和中间件。
+- **受影响的端点**: 全部。
+
+#### Scenario: 所有现有的 API 端点保持功能齐全和向后兼容
+- **假如**: API 服务器在迁移到 Echo 后正在运行。
+- **当**: 客户端向任何现有的 API 端点（例如, `POST /api/v1/users/login`）发送请求。
+- **那么**: 服务器处理该请求并返回与使用 Gin 框架时完全相同的响应（状态码、头部和正文格式）。
