Changes Made

• Removed cnblogs entry from LOGIN_CHECK_CONFIG in configs.js
• Added new detectCnblogsUser function in platforms/cnblogs.js
• Integrated detectCnblogsUser into PLATFORM_DETECTORS map in detect.js
• Implemented MV3 service worker compatible cookie collection mechanism

Implementation Details

Key Changes:

1. New Detection Strategy: Implemented a three-step detection process:

   • Collect cookies via chrome.cookies.getAll() API (MV3 compatible)
   • Fetch user info from account.cnblogs.com/user/userinfo with cookies attached manually
   • Extract username and avatar from API response

2. Cookie Collection: Gather cookies from multiple domains (.cnblogs.com, www.cnblogs.com, account.cnblogs.com) and deduplicate them to ensure proper authentication.

3. Avatar Handling: Process avatar URLs by:

   • Converting protocol-relative URLs to HTTPS
   • Converting Cnblogs-hosted avatars to Base64 format

Technical Notes:

• Used chrome.cookies.getAll() instead of DOM-based detection to ensure compatibility with MV3 service workers
• Implemented proper error handling with try-catch blocks
• Returns structured response with loggedIn, username, and avatar fields
• Falls back gracefully with { loggedIn: false } on any error
