私有资源认证

一、 架构设计与请求流转核心流程图客户端(浏览器)│ ▼(1. 请求受保护资源 /secure/data.pdf 或 /api/user/info)┌─────────────────────────────────────────────────────┐ │ Nginx(反向代理静态资源服务器)│ │ ├─(2)拦截请求发起内部子请求(auth_request)│ │ │ └─转发至 /_auth(携带 Cookie/Token, 原始URI)│ │ │ │ │ ├─(3)接收 Spring Boot 鉴权结果 │ │ │ ├─200OK: 提取用户信息放行请求 │ │ │ ├─401Unauthorized: 重定向到登录页或返回401 │ │ │ └─403Forbidden: 返回无权限页面 │ │ │ │ │ └─(4)鉴权通过将请求转发给后端业务服务或返回静态文件│ └─────────────────────────────────────────────────────┘ │ ▼ ┌─────────────────────────┐ ┌─────────────────────────┐ │ Spring Boot(鉴权服务)│ │ Spring Boot(业务服务)│ │ - 校验 Token/JWT │ │ - 直接读取 Nginx 传来的 │ │ - 校验 URL/RBAC 权限 │ │ X-User-Id 等 Header │ │ - 返回200/401/403 │ │ - 无需再解析 Token │ └─────────────────────────┘ └─────────────────────────┘二、 Nginx 生产级配置在生产环境中Nginx 配置需要处理凭证传递、原始 URI 传递、错误重定向、以及跨域预检OPTIONS放行。. --with-http_auth_request_module 添加auth模块# 定义上游服务upstream auth_backend{server127.0.0.1:8080;# Spring Boot 鉴权服务keepalive64;# 生产环境必须开启长连接降低子请求延迟}upstream
