_wait_for_login(): Poll with configurable timeout (tenacity) - login_by_qrcode(): Main entry point for login flow Key design decisions: - Uses tenacity Retrying for configurable timeout - QR code saved to intermediate_path with timestamp -

| +| python-dotenv | 1.0+ | 环境变量加载 | 代理配置读取 | + +### Alternatives Considered +| Instead of | Could Use | Tradeoff | +|------------|-----------|----------| +| Playwright route | requests + 逆向签名 | 需要持续维护签名算法，Playwright 方式更稳定 | +| 直接调用 API | Selenium + DOM 解析 | DOM 结构变化频繁，API 响应更稳定 | + +**Installation:** +```bash +# 已安装，无需额外安装 +playwright install chromium # 如需更新浏览器 +``` + +## Architecture Patterns + +### Recommended Project Structure +``` +kb_workflow/ +├── crawler/ # 新建爬虫模块 +│ ├── __init__.py +│ ├── zhihu_crawler.py # 主爬虫类 +│ ├── api_interceptor.py # API 拦截逻辑 +│ ├── models.py # 响应数据模型

Interception +**What:** 拦截浏览器发出的 API 请求，直接获取 JSON 响应 +**When to use:** 获取结构化数据，避免 DOM 解析 +**Example:** +```python +# Source: https://playwright.dev/python/docs/network +from playwright.sync_api import sync_playwright + +def intercept_api(route): + """拦截知乎 API 请求""" + if "/api/v4/" in route.request.url: + # 继续请求以获取响应 + response = route.fetch() + json_data = response.json() + # 存储拦截到的数据 + route.fulfill(response=response) + else: + route.continue_() + +with sync_playwright() as p: + browser = p.chromium.launch() + page = browser.new_page() + page.route("**/api/v4/**", intercept_api) + page.goto("https://www.zhihu.com/question/123/answer/456") +``` + +### Pattern 2: 代理配置 +**What:** 通过环境变量配置代理，在 Playwright 中应用 +**When to use:** 所有爬取请求，防止 IP 被封 +**Example:** +```python +# Source: https://playwright.dev/python/docs/network +import os +from playwright.sync_api import sync_playwright + +def get_proxy_config(): + """从环境变量获取代理配置""" + proxy_server = os.environ.get("HTTP_PROXY") or os.environ.get("HTTPS_PROXY") + if proxy_server: + # 解析代理 URL + # http://user:pass@host:port 或 http://host:port + return {"server": proxy_server} + return None + +# 在 new_context 中应用代理 +browser = chromium.launch() +context = browser.new_context(proxy=get_proxy_config()) +``` + +### Pattern 3: 随机延迟与重试 +**What:** 请求间随机延迟，失败时有限重试 +**When to use:** 所有网络请求 +**Example:** +```python +import random +import time +from tenacity import Retrying, stop_after_attempt, wait_exponential + +def crawl_with_retry(crawl_func, url): + """带重试的爬取""" + for attempt in Retrying( + stop=stop_after_attempt(3), + wait=wait_exponential(multiplier=1, min=2, max=10), + reraise=True + ): + with attempt: + # 随机延迟 + time.sleep(random.uniform(1, 3)) + return crawl_func(url) +``` + +### Anti-Patterns to Avoid +- **硬编码延迟时间:** 使用固定延迟容易被检测，应使用随机值 +- **忽略代理检查:** 不检查代理配置直接爬取可能导致 IP 被封 +- **无限重试:** 重试次数应有限制，避免无限循环 + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| 请求重试 | 自定义重试循环 | tenacity.Retrying | 支持指数退避、超时、回调 | +| API 签名 | 逆向 x-zse-96 算法 | Playwright 浏览器自动处理 | 签名算法频繁更新，逆向成本高 | +| Cookie 管理 | 手动解析存储 | 现有 ZhihuLogin + PlaywrightBrowser | 已有成熟实现 | +| 代理解析 | 自定义 URL 解析 | Playwright proxy 参数 | 支持认证、SOCKS5 | + +**Key insight:** Playwright 拦截模式的核心优势是复用浏览器的完整上下文（Cookie、签名、指纹），无需维护逆向代码。 + +## Common Pitfalls + +### Pitfall 1: Service Worker 干扰 +**What goes wrong:** 使用 `page.route()` 时某些请求未被捕获 +**Why it happens:** Service Worker 拦截了网络请求 +**How to avoid:** 在 `new_context()` 中设置 `service_workers="block"` +**Warning signs:** API 拦截处理器未被调用 + +```python +context = browser.new_context(service_workers="block") +``` + +### Pitfall 2: 代理未生效 +**What goes wrong:** 配置了环境变量但请求仍使用直连 +**Why it happens:** Playwright 默认不读取环境变量 +**How to avoid:** 显式读取环境变量并传入 `new_context(proxy=...)` +**Warning signs:** IP 被封、请求频率限制 + +### Pitfall 3: 评论 API 分页处理 +**What goes wrong:** 只获取了第一页评论 +**Why it happens:** 评论 API 使用 cursor 分页 +**How to avoid:** 使用 `offset` 参数处理分页，但根据决策只爬热门评论（单页） +**Warning signs:** 评论数量固定为 20 条 + +### Pitfall 4: Cookie 过期未检测 +**What goes wrong:** 爬取时返回登录页面 +**Why it happens:** Cookie 已过期但未提前验证 +**How to avoid:** 爬取前调用 `/api/v4/me` 验证 Cookie 有效性 +**Warning signs:** 响应包含"登录"关键词 + +## Code Examples + +Verified patterns from official sources: + +### API 拦截存储响应 +```python +# Source: https://playwright.dev/python/docs/network +class ZhihuApiInterceptor: + """知乎 API 拦截器""" + + def __init__(self): + self.captured_data = {} + + def handle_route(self, route): + """处理拦截的请求""" + url =

DownloadProcessor 依赖接口稳定 +- **不要在 ZhihuCrawler 中添加 Pipeline 逻辑**: 保持爬虫职责单一 +- **不要同步阻塞调用爬虫**: 使用 asyncio.to_thread 包装 +- **不要忽略 Cookie 过期**: 必须触发扫码登录流程 + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| HTML to Markdown | 自定义转换器 | MarkdownConverter (已存在) | zhihu_extractor.py 已有 | +| Cookie 解析 | 手动解析 cookie 字符串 |

ZhihuCrawler 已完整实现问答/专栏/评论爬取，只需要正确调用和结果转换。 + +## Common Pitfalls + +### Pitfall 1: CrawlResult 到 Metadata Dict 转换不完整 +**What goes wrong:** ZhihuCrawler 返回 CrawlResult(AnswerData/ArticleData)，但 DownloadProcessor 期望特定格式的 metadata dict +**Why it happens:** 数据模型不完全匹配 +**How to avoid:** 实现 _convert_crawl_result_to_metadata() 转换函数，确保所有字段正确映射 +**Warning signs:** DownloadProcessor 提取 title/author 时返回空字符串 + +### Pitfall 2: 评论未正确追加到正文 +**What goes wrong:** fetch_content() 返回的内容不包含评论 +**Why it happens:** include_comments=True 未正确传递或评论格式化逻辑遗漏 +**How to avoid:** fetch_content() 必须调用 fetch_metadata(include_comments=True)，格式化时追加评论 +**Warning signs:** 输出 Markdown 文件无评论部分 + +### Pitfall 3: Cookie 过期检测不准确 +**What goes wrong:** 误判 Cookie 有效/无效，导致不必要的登录或无限重试 +**Why it happens:** 仅依赖 HTTP 状态码，未检查响应内容 +**How to avoid:** 检查 API 响应中的 error 字段和 401/403 状态码 +**Warning signs:** 登录循环或认证错误未触发 + +### Pitfall 4: asyncio.to_thread 调用错误 +**What goes wrong:** ZhihuCrawler 方法调用参数传递不正确 +**Why it happens:** to_thread 需要函数引用和参数分开传递 +**How to avoid:** `await asyncio.to_thread(crawler.crawl_answer, url, include_comments=True)` +**Warning signs:** TypeError: 'CrawlResult' object is not callable + +## Code Examples + +### ZhihuCrawler Usage (from existing code) + +```python +# Source: kb_workflow/crawler/zhihu_crawler.py +crawler = ZhihuCrawler(headless=True, timeout=30) + +# 爬取回答（含评论） +result = crawler.crawl_answer( + url="https://www.zhihu.com/question/123/answer/456", + include_comments=True +) +# result = CrawlResult(success=True, content_type="answer", data=AnswerData, comments=[...])
