Phase 7 Plan 1: QR Code Login Core Summary

ZhihuLogin class implementing QR code login flow: navigate to signin page, capture canvas screenshot, poll for z_c0 cookie with configurable timeout

Performance

• Duration: 15 min
• Started: 2026-03-17T09:47:15Z
• Completed: 2026-03-17T10:02:48Z
• Tasks: 2
• Files modified: 5

Accomplishments

• Created Wave 0 test scaffolding with pytest fixtures for mocking PlaywrightBrowser
• Implemented ZhihuLogin class with full QR code login flow
• All 8 unit tests passing with TDD approach
• Configurable timeout via tenacity Retrying (default 60 seconds)

Task Commits

Each task was committed atomically:

1. Task 1: Create test module and fixtures - f90de6b (test)
2. Task 2: Implement ZhihuLogin core class - fb9bc2d (test - TDD RED) + 072d83d (feat - TDD GREEN)

Note: TDD tasks have multiple commits (test -> feat)

Files Created/Modified

• kb_workflow/auth/__init__.py - Module exports ZhihuLogin and ZhihuLoginResult
• kb_workflow/auth/zhihu_login.py - Core login implementation (175 lines)
• tests/test_auth/__init__.py - Test module init
• tests/test_auth/conftest.py - Pytest fixtures (mock_browser, sample_cookies, etc.)
• tests/test_auth/test_qrcode_login.py - 8 unit tests for login flow

Decisions Made

• Used tenacity Retrying object instead of @retry decorator to support configurable timeout per instance
• Multiple canvas selectors (canvas.SignIn-qrcode, canvas[class*='qrcode'], canvas) for robustness against UI changes
• QR code filename format: zhihu_qrcode_{timestamp}.png in intermediate directory

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Fixed tenacity reraise behavior in timeout test

• Found during: Task 2 (TDD GREEN phase)
• Issue: Test expected RetryError but reraise=True re-raises the original exception
• Fix: Updated test to expect Exception with message "Not logged in yet"
• Files modified: tests/test_auth/test_qrcode_login.py
• Verification: All 8 tests pass
• Committed in: 072d83d (Task 2 GREEN commit)

---

Total deviations: 1 auto-fixed (1 bug) Impact on plan: Minor test adjustment, no functional impact

Issues Encountered

• Initial @retry decorator had hardcoded 60-second timeout - switched to Retrying object for instance-level configuration

User Setup Required

None - no external service configuration required for this plan.

Next Phase Readiness

• ZhihuLogin class ready for integration in 07-02 (Cookie persistence)
• Test fixtures can be reused for cookie import testing
• Need to add CLI command integration in 07-03
