#普通登录存到session和cookie
# 1浏览器每次请求 → 自动带上这个 session Cookie
# 2服务器拿到 Cookie → 解密 → 得到 user_info
# 3服务器判断：你已登录
# 为什么由session改成redis
# 1登录流程：账号密码校验通过 → 生成唯一 Token → Token + 用户信息存入 Redis（带过期）→ Token 写入浏览器 Cookie
# 2访问流程：前端请求接口 → 自动携带 Cookie 里的 Token → 后端从 Redis 查 Token 是否有效 → 有效则放行，无效跳登录
# 3退出流程：删除 Redis 里的 Token → 删除浏览器 Cookie → 彻底登出
# 细节问题:
# Redis key 前缀login:token:，和你原来的队列 key 完全隔离，不会冲突
# Token 用 uuid 全局唯一，不会重复、不会被猜解
# Redis 自动过期 + 访问自动续期，闲置 30 分钟自动登出
# 只存用户名，不存明文密码到 Redis，更安全import redis
