研究方向

Investigate the current authentication flow in the backend, likely using JWT. Identify where tokens are generated and verified (e.g., in auth routes). Review existing comments in the issue (#204) for any discussion on implementation details. Propose a solution using a refresh token stored in an httpOnly cookie instead of localStorage for better security. Consider adding a token refresh endpoint and updating the frontend to handle token expiration.
