Instructions

操作指南

RESTful Conventions:
- Use correct HTTP verbs (GET, POST, PUT, DELETE).
- Use nouns for resource paths (e.g., /users, /orders/{id}).
- Implement pagination for list endpoints (e.g., ?page=1&limit=50).
Data Contracts:
- Use standard status codes (200, 201, 400, 401, 403, 404, 500).
- Standardize response envelopes (e.g., { data: ..., error: ... }).
- Validate input strictly (types, ranges, formats).
Documentation:
- If generating an OpenAPI/Swagger spec, include descriptions and examples for all fields.
Versioning:
- Recommend URL versioning (e.g., /v1/users) if breaking changes are likely.

RESTful 规范：
- 使用正确的HTTP动词（GET、POST、PUT、DELETE）。
- 资源路径使用名词（例如：/users、/orders/{id}）。
- 列表端点实现分页功能（例如：?page=1&limit=50）。
数据契约：
- 使用标准状态码（200、201、400、401、403、404、500）。
- 统一响应包格式（例如：{ data: ..., error: ... }）。
- 严格验证输入（类型、范围、格式）。
文档：
- 如果生成OpenAPI/Swagger规范，需包含所有字段的描述和示例。
版本控制：
- 如果可能存在破坏性变更，建议使用URL版本控制（例如：/v1/users）。
