前后端分离不只是把前端和后端放到两个仓库。从 API 设计到部署策略，这 7 个实践帮你把分离架构做对。
Frontend-backend separation isn't just putting code in two repos. These 7 practices help you implement the architecture correctly.
1. API 先行设计在写一行代码之前，先用 OpenAPI/Swagger 定义接口文档。前后端根据文档并行开发，而不是后端写完等前端联调。2. 统一响应格式所有接口返回统一的 JSON 结构：{ code, msg, data }。前端可以用一个拦截器统一处理成功和错误。3. RESTful 资源命名URL 用名词不用动词：/api/users 而不是 /api/getUsers。用 HTTP 方法表示操作：GET 查询、POST 创建、PUT 更新、DELETE 删除。4. 分页标准化分页参数用 page 和 size，返回 records、total、page、size。所有列表接口保持一致。5. 认证用 JWT无状态的 JWT Token 适合前后端分离架构。Token 放在 Authorization Header 里，不要放 Cookie（避免 CSRF）。6. CORS 正确配置只允许你的前端域名跨域请求，不要用 *。生产环境要明确指定允许的 Origin。7. 独立部署前端打包为静态文件，用 Nginx 或 CDN 托管。后端独立部署为 API 服务。两者可以独立发版，互不影响。
1. API-First DesignBefore writing a single line of code, define the API documentation with OpenAPI/Swagger. Frontend and backend develop in parallel based on the spec.2. Unified Response FormatAll endpoints return a consistent JSON structure: { code, msg, data }. Frontend uses one interceptor to handle success and errors uniformly.3. RESTful Resource NamingURLs use nouns, not verbs: /api/users instead of /api/getUsers. HTTP methods express operations: GET for queries, POST for creation, PUT for updates, DELETE for removal.4. Pagination StandardsUse page and size parameters, return records, total, page, size. Keep all list endpoints consistent.5. JWT AuthenticationStateless JWT tokens suit frontend-backend separation. Put tokens in the Authorization Header, not cookies (avoids CSRF).6. Proper CORS ConfigurationOnly allow your frontend domain for cross-origin requests — never use *. Production must explicitly specify allowed origins.7. Independent DeploymentFrontend builds to static files hosted on Nginx or CDN. Backend deploys as an independent API service. Both can release independently.
