Original Pull Request: https://github.com/langgenius/dify/pull/27190

State: closed
Merged: Yes

Fixes #27189

Which enable Next.js running like dify.thape.com.cn and Backend running like diff-api.thape.com.cn

Summary

  • api/libs/token.py:32-159 now strips an optional COOKIE_DOMAIN, skips the __Host- prefix when it’s set, and applies the Domain attribute to every console/session cookie so they can flow between dify-api and dify.
  • api/configs/feature/__init__.py:340-343 exposes COOKIE_DOMAIN; see the usage notes added to api/.env.example:159-161 (and mirrored in web/.env.example:37-38) for deployment guidance.
  • api/tests/unit_tests/libs/test_token.py:30-58 adds regression coverage for both host-only and shared-domain cookie scenarios.
  • web/config/index.ts:147-151 respects NEXT_PUBLIC_COOKIE_DOMAIN, ensuring the browser now grabs the plain csrf_token cookie when you share it across subdomains.

Checklist

  • This change NOT requires a documentation update, included: Dify Document
  • I understand that this PR may be closed in case there was no previous discussion or issues. (This doesn't apply to typos!)
  • I've added a test for each change that was introduced, and I tried as much as possible to make a single atomic change.
  • No need updated the documentation accordingly.
  • I ran dev/reformat(backend) and cd web && npx lint-staged(frontend) to appease the lint gods
