Instructions

操作指南

  1. 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).
  2. 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).
  3. Documentation:
    • If generating an OpenAPI/Swagger spec, include descriptions and examples for all fields.
  4. Versioning:
    • Recommend URL versioning (e.g., /v1/users) if breaking changes are likely.
  1. 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)。
  2. 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)。
  3. 文档:
    • 如果生成OpenAPI/Swagger规范,需包含所有字段的描述和示例。
  4. 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)。
