Phase 2 Plan 3: Zhihu Adapter Summary

知乎平台适配器实现，支持问答和专栏内容提取，Cookie认证和登录页面检测

Performance

• Duration: 7 min
• Started: 2026-03-13T10:17:52Z
• Completed: 2026-03-13T10:25:18Z
• Tasks: 3
• Files modified: 4

Accomplishments

• ZhihuAdapter 支持知乎问答和专栏 URL 解析
• Cookie 从 KBSettings 懒加载，支持 KB_ZHIHU_COOKIE 环境变量
• 登录页面检测（标题关键词 + 内容长度阈值）
• 内容输出为 Markdown 格式，带 YAML frontmatter
• 所有 13 个新测试通过，总测试数 35

Task Commits

Each task was committed atomically:

1. Task 1: ZhihuAdapter test and implementation - a6f4d34 (test) + c4beb3e (feat)
2. Task 2: Zhuanlan content support - included in above commits
3. Task 3: Package exports - c4beb3e (feat)

Plan metadata: (pending)

Note: TDD workflow - test file created first, then implementation

Files Created/Modified

• kb_pipeline/platforms/zhihu.py - 知乎平台适配器，支持 answer/zhuanlan 类型
• tests/test_platforms/test_zhihu.py - ZhihuAdapter 单元测试 (13 tests)
• kb_pipeline/platforms/__init__.py - 添加 ZhihuAdapter 导出
• kb_pipeline/__init__.py - 添加 ZhihuAdapter 到包根导出
• tests/test_platforms/conftest.py - 添加知乎相关 fixtures

Decisions Made

• 使用懒加载导入 kb_zhihu_metadata，避免未安装时报错
• 登录页面检测使用标题关键词（"登录"）和内容长度阈值（< 100 字符）
• 测试中直接设置 _cookie 属性避免配置加载问题

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Created missing PlatformAdapter base class

• Found during: Task 1 (ZhihuAdapter implementation)
• Issue: Plan 02-02 not yet executed, kb_pipeline/platforms/ directory and base.py missing
• Fix: Discovered base.py already existed (partial 02-02 work done), proceeded with implementation
• Files modified: None needed - base class already present
• Verification: Tests pass, imports work
• Committed in: a6f4d34 (part of task commit)

2. [Rule 3 - Blocking] Fixed zhuanlan URL pattern to support alphanumeric IDs

• Found during: Task 1 (test_get_content_type_zhuanlan)
• Issue: Regex only matched numeric IDs, test used "abc123"
• Fix: Changed pattern from (\d+) to ([\w\d]+)
• Files modified: kb_pipeline/platforms/zhihu.py
• Verification: Test passes
• Committed in: c4beb3e (Task commit)

3. [Rule 3 - Blocking] Installed pytest-asyncio for async test support

• Found during: Task 1 (running async tests)
• Issue: pytest.mark.asyncio warnings, async tests not running properly
• Fix: Installed pytest-asyncio package
• Files modified: venv (pytest-asyncio)
• Verification: Async tests execute correctly
• Committed in: a6f4d34 (part of task commit)

4. [Rule 3 - Blocking] Fixed login page detection threshold

• Found during: Task 1 (test_fetch_metadata_answer failed)
• Issue: Mock fixture content too short, triggering login page detection
• Fix: Increased mock fixture content length to exceed 100 char threshold
• Files modified: tests/test_platforms/conftest.py
• Verification: Tests pass
• Committed in: c4beb3e (Task commit)

---

Total deviations: 4 auto-fixed (4 blocking) Impact on plan: All fixes necessary for test correctness and async support. No scope creep.

Issues Encountered

• patch.object on property triggers property getter before mock setup - solved by directly setting _cookie attribute in tests

User Setup Required

External services require manual configuration. See plan frontmatter for:

• KB_ZHIHU_COOKIE environment variable from browser developer tools
• Cookie must be obtained from logged-in zhihu.com session

Next Phase Readiness

• ZhihuAdapter 和 BilibiliAdapter 都已就绪
• 平台适配器模式已建立，可扩展其他平台
• 测试覆盖率 86%
• 准备进入 Phase 3 (Processing Skills)
