+# 项目交接说明
+
+更新时间：2026-03-18  
+项目根目录：`/Users/mac/Documents/my_site`
+
+## 1. 项目概况
+
+这是一个前后端分离的个人门户项目：
+
+- 前端：`front/`
+- 后端：`backend/`
+- 线上主站：`https://yoyuzh.xyz`
+- 线上 API：`https://api.yoyuzh.xyz`
+
+主要功能：
+
+- 登录 / 注册
+- 网盘文件列表与最近文件
+- 教务相关接口（课表 / 成绩）
+
+## 2. 当前线上架构
+
+当前建议保持的生产架构是：
+
+- `yoyuzh.xyz`：继续走 OSS / ESA，负责静态站点
+- `api.yoyuzh.xyz`：直接指向后端服务器，不要继续走 ESA 代理
+
+原因：
+
+- 主站静态资源走 ESA 没问题
+- API 一旦走 ESA，之前出现过：
+  - `525 Origin SSL Handshake Error`
+  - `ERR_CONNECTION_CLOSED`
+  - `ERR_EMPTY_RESPONSE`
+- 当前最稳方案是“静态站加速，API 直连”
+
+## 3. 当前前端生产配置
+
+文件：
+
+- `front/.env.production`
+
+当前应保持为：
+
+```env
+VITE_API_BASE_URL="https://api.yoyuzh.xyz/api"
+VITE_ROUTER_MODE="hash"
+VITE_ENABLE_DEV_LOGIN="false"
+```
+
+说明：
+
+- 不要再切回同域 `/api`，除非以后重新正确配置边缘转发
+- 目前生产前端已经恢复为直连 `api.yoyuzh.xyz`
+
+## 4. 当前已完成的前端改动
+
+### 4.1 登录页
+
+`front/src/pages/Login.tsx`
+
+- 已替换为模板版登录 / 注册页
+- 登录调用：`POST /auth/login`
+- 注册调用：`POST /auth/register`
+- 登录成功后写入 session 并跳转 `/overview`
+
+### 4.2 网络错误处理
+
+`front/src/lib/api.ts`
+
+- 对网络错误统一包装为更清晰的前端错误
+- 登录和只读接口有轻量重试机制
+- 当前策略是“尽量兜底，但不要把登录拖到 7-8 秒”
+
+### 4.3 登录成功与总览初始化失败拆分提示
+
+相关文件：
+
+- `front/src/lib/session.ts`
+- `front/src/pages/Overview.tsx`
+- `front/src/pages/overview-state.ts`
+
+已做：
+
+- 登录成功后会标记一次“post-login pending”
+- `/overview` 初始化失败时，会提示“登录已成功，但总览加载失败”
+- 避免把 overview 并发初始化失败误判成登录失败
+
+## 5. 当前后端与服务器状态
+
+通过 SSH 已确认：
+
+- `my-site-api.service` 正常运行
+- 后端本机 `127.0.0.1:8080` 正常
+- 服务器本机直打登录接口返回 `200`
+- Nginx 正常反代 `api.yoyuzh.xyz -> 127.0.0.1:8080`
+
+服务器上关键配置：
+
+- Nginx：`/etc/nginx/sites-enabled/my-site-api`
+- 后端配置：`/opt/yoyuzh/application-prod.yml`
+- 服务名：`my-site-api.service`
+
+## 6. 线上排查结论
+
+### 6.1 已确认不是后端业务慢
+
+在服务器本机测试结果：
+
+- `POST http://127.0.0.1:8080/api/auth/login` 约 `95ms`
+- `POST https://api.yoyuzh.xyz/api/auth/login` 从服务器发起约 `681ms`
+
+所以：
+
+- 后端本身不是“登录 5 秒”的根因
+
+### 6.2 之前登录很慢的主要原因
+
+更像是以下问题叠加：
+
+- 旧 DNS / 旧代理链路未收敛
+- API 域名曾被 ESA 代理，导致 TLS / 回源问题
+- 浏览器前链路偶发 `ERR_CONNECTION_CLOSED`
+
+### 6.3 当前更可信的状态
+
+服务器日志已经看到真实浏览器请求成功：
+
+- `OPTIONS /api/auth/login` => `200`
+- `POST /api/auth/login` => `200`
+- `/api/user/profile` => `200`
+- `/api/files/recent` => `200`
+- `/api/files/list` => `200`
+- `/api/cqu/*` => `200`
+
+因此：
+
+- 现在如果仍有个别客户端不稳定，优先怀疑本地 DNS / 浏览器缓存 / 本地网络链路
+
+## 7. DNS / ESA 方面的重要结论
+
+### 7.1 过去踩过的坑
+
+不要再轻易做下面这件事：
+
+- 让 `yoyuzh.xyz/api/*` 通过 ESA 回源到 API
+
+之前已经明确踩到：
+
+- `/api/*` 误回 OSS，报 `403 NonCnameForbidden`
+- 回源 HTTPS 握手失败，报 `525 Origin SSL Handshake Error`
+
+### 7.2 当前建议
+
+- `yoyuzh.xyz`：可以继续 ESA
+- `api.yoyuzh.xyz`：不要走 ESA 代理
+
+### 7.3 用户侧现象
+
+曾出现：
+
+- 无痕模式能登录
+- 本机 `dig` 还查到旧的 `198.18.0.148`
+
+这说明某一阶段存在 DNS 传播不一致。  
+如果下一个 Codex 遇到“浏览器能用，命令行不行”的情况，先查 DNS 链路，不要直接改代码。
+
+## 8. OSS 前端部署方式
+
+已经写好自动部署脚本：
+
+- `scripts/deploy-front-oss.mjs`
+- 配套库：`scripts/oss-deploy-lib.mjs`
+- 配置模板：`.env.oss.example`
+
+### 8.1 本地使用方式
+
+先准备：
+
+```bash
+cp .env.oss.example .env.oss.local
+```
+
+然后填入 OSS 参数。
+
+### 8.2 发布命令
+
+```bash
+./scripts/deploy-front-oss.mjs
+```
+
+### 8.3 只看将要上传什么
+
+```bash
+./scripts/deploy-front-oss.mjs --skip-build --dry-run
+```
+
+### 8.4 部署逻辑
+
+脚本会：
+
+- 读取 `.env.oss.local`
+- 构建 `front/dist`
+- 上传到 OSS
+- 自动设置缓存头
+
+缓存策略：
+
+- `index.html` => `no-cache`
+- `assets/*` => `public,max-age=31536000,immutable`
+
+## 9. 测试账号
+
+开发测试账号文档：
+
+- `开发测试账号.md`
+
+常用账号：
+
+- `portal-demo / portal123456`
+
+注意：
+
+- 这些开发账号只在特定环境下才会自动初始化
+- 如果线上账号密码不对，不要默认认为后端坏了
+
+## 10. SSH 与敏感信息
+
+有 SSH 凭据文件：
+
+- `账号密码.txt`
+
+下一个 Codex 可以读取该文件用于 SSH，但不要在普通交互回复里直接回显其中的明文密码。
+
+## 11. 推荐的排查顺序
+
+如果后续又出现“登录失败 / 网络连接异常”，按这个顺序排：
+
+1. 先查前端当前生产包是否正确
+   - 看 `https://yoyuzh.xyz/` 的 `index.html`
+   - 确认引用的是最新构建产物
+
+2. 再查 API 域名是否直连服务器
+   - `dig +short api.yoyuzh.xyz`
+   - `curl -vkI https://api.yoyuzh.xyz/`
+
+3. 再查服务器本机和 systemd
+   - `systemctl status my-site-api`
+   - `curl http://127.0.0.1:8080/...`
+
+4. 最后查 Nginx access/error log
+   - `/var/log/nginx/access.log`
+   - `/var/log/nginx/error.log`
+
+不要上来就改前端逻辑。
+
+## 12. 当前最重要的改进建议
+
+### 短期建议
+
+- 保持 API 直连，不再给 `api.yoyuzh.xyz` 套 ESA
+- 用现有自动部署脚本发布前端
+
+### 中期建议
+
+- 给后端加一个明确的健康检查接口，比如 `/api/healthz`
+- 给 Nginx access log 加 upstream timing 和 request id
+
+### 长期建议
+
+- 如果未来还想做同域 `/api`，要单独做一轮边缘转发设计
+- 先确保：
+  - 源站类型正确
+  - 不会回 OSS
+  - 不会再发生 `525`
+
+## 13. 给下一个 Codex 的一句话总结
+
+当前项目已经从“链路混乱”恢复到“后端基本正常、主站正常、前端直连 API”的状态。  
+接手时优先维持现状，不要贸然重新启用 ESA 的 `/api` 回源方案。
