Phase 09 Plan 01: ZhihuAdapter Integration Summary

ZhihuAdapter integrated with ZhihuCrawler, supporting comment crawling, cookie auto-login, and idempotent execution

Performance

• Duration: 11 min
• Started: 2026-03-17T15:04:22Z
• Completed: 2026-03-17T15:15:11Z
• Tasks: 3
• Files modified: 2

Accomplishments

• ZhihuAdapter now uses ZhihuCrawler instead of ZhihuPlaywrightExtractor
• Comments are included by default and appended to content in Markdown format
• Cookie expiration triggers automatic QR code login flow
• Idempotent execution via IdempotencyChecker when output_dir is configured

Task Commits

Each task was committed atomically:

1. Task 1: Update ZhihuAdapter to use ZhihuCrawler - 76f06c3 (feat)
   • Includes Task 2 (Cookie auto login) and Task 3 (Comment formatting + idempotency)

Plan metadata: (to be committed after this summary)

Note: All three tasks were completed in a single commit due to tight integration between the components

Files Created/Modified

• kb_workflow/pipeline/platforms/zhihu.py - Core adapter implementation with ZhihuCrawler integration
• tests/test_platforms/test_zhihu.py - Complete test suite with 19 passing tests

Decisions Made

• Used ZhihuCrawler for content extraction (replacing ZhihuPlaywrightExtractor)
• Comments included by default (include_comments=True)
• Cookie expiration detected via error message keywords (login, expired, etc.)
• QR code login with 2-minute timeout and visible browser window
• HTML to Markdown conversion using html2text library

Deviations from Plan

None - plan executed exactly as written. All three tasks were integrated into a single implementation because:

1. Task 1 requires TDD tests that cover Task 2 and Task 3 scenarios
2. Cookie handling and comment formatting are integral parts of the adapter implementation
3. Separating commits would require partial/incomplete code

Issues Encountered

Missing dependency (Rule 3 - Blocking): html2text package was not installed in the virtual environment. Fixed by installing via pip install html2text.

User Setup Required

None - no external service configuration required beyond the existing Zhihu cookie setup.

Next Phase Readiness

• ZhihuAdapter is ready for integration with DownloadProcessor
• All 19 tests passing, covering:
  • Basic content type detection
  • Metadata and content fetching
  • Cookie handling and auto-login
  • Comment formatting
  • Idempotency
