Closed by v5 deployment. Sticky proxy sessions (ao3_sessid_proxy cookie) now keep users on one proxy for the entire session, preventing CSRF token mismatch across proxy switches.

诊断更新

已部署修复（3 项）

  1. Origin/Referer 头重写 — 浏览器发 → 重写为 ，通过 AO3 CSRF 校验
  2. 粘性会话强化 — 有 session cookie 的请求不换代理，防止 CSRF/session 跨代理不匹配
  3. CF Challenge 路径映射 — → 绕过我们的 CF CDN，challenge JS 能正确加载

当前状态

  • ✅ GET /users/login — 200，CSRF + session cookie 正常获取
  • ✅ Sticky proxy 跨请求保持一致（同一代理 2857）
  • ⚠️ POST /users/login — 返回 Session Expired + CF inline challenge
  • ⚠️ curl 无法执行 CF JS，需要真实浏览器测试

期望流程（浏览器）

  1. GET login → CSRF + session cookie
  2. POST login → CF challenge 检测 → 返回 challenge 页面（200 + auto-refresh 6s）
  3. 浏览器执行 CF JS → 路径代理到 AO3 → 解 challenge → cf_clearance 写入代理
  4. 6 秒后 auto-refresh → 重新 POST → 代理有 cf_clearance → AO3 接受登录

请在浏览器中测试登录，观察是否出现 challenge solving → auto-refresh → 登录成功。

Auto-triage report: Issue is a legitimate bug about session expired / CSRF validation failures when proxying to AO3. Labels (bug, priority:high) and assignee (@akiba) already correctly set. The v5 fix was deployed but latest test still shows session expired -- needs further browser-based testing. Keeping open.

Triage Summary

Issue: Bug #2 - session expired / CSRF validation failure

Status: Still open

  • Issue body says "Closed by v5 deployment" but latest test (comment #1305) reports "没有成功 session expired" - fix not verified
  • Labels: bug, priority:high - correct
  • Assignee: @akiba - correct

Next steps:

  1. Test login in a real browser (CF challenge needs JS execution)
  2. Verify sticky proxy session cookie persists across login POST
  3. If confirmed working, update issue body to reflect actual status and close
  4. If not fixed, investigate CF challenge solving in proxy layer

Note: Keeping open until browser-verified.
