Summary

实现了知乎问答和专栏内容爬取功能，使用 Playwright 拦截 API 请求获取结构化 JSON 数据。

What Was Built

ZhihuCrawler 类 (kb_workflow/crawler/zhihu_crawler.py)

crawl_answer(url) - 爬取知乎问答，返回 AnswerData
crawl_article(url) - 爬取知乎专栏，返回 ArticleData
API 拦截器 ZhihuApiInterceptor 捕获 /api/v4/answers/ 和 /api/v4/articles/ 响应
DOM 解析备选方案（使用 ZhihuPlaywrightExtractor）

数据模型 (kb_workflow/crawler/models.py)

AuthorInfo - 作者信息（名称、URL token、签名）
ContentMetadata - 内容元数据（作者、点赞数、评论数、时间戳）
AnswerData - 问答数据（ID、问题ID、标题、内容、摘要、元数据）
ArticleData - 专栏数据（ID、标题、内容、摘要、元数据）
CrawlResult - 统一结果包装（成功/失败、内容类型、数据/错误）

Test Coverage

15 个测试全部通过

test_answer_crawler.py - 5 个测试
test_article_crawler.py - 4 个测试
test_metadata_extraction.py - 6 个测试

Commits

a102a75 feat(08-01): create crawler data models and test scaffolding
912773f test(08-01): add failing tests for ZhihuCrawler
aa96bc9 feat(08-01): implement ZhihuCrawler with API interception

Key Decisions

API 拦截 vs 直接 API 调用: 使用 Playwright page.route() 拦截浏览器请求，自动处理签名和 Cookie
TDD 工作流: 先写测试，使用 mock fixtures 确保测试可维护性
备选方案: 当 API 拦截失败时，回退到 DOM 解析

Requirements Completed

CONT-01: 爬取知乎问答，获取问题标题、描述、回答内容 ✓
CONT-02: 爬取知乎专栏/文章，获取标题和正文 ✓
CONT-04: 爬取结果包含作者信息、发布时间、点赞数等元数据 ✓
