# Requirements: v1.4 Zhihu Anti-Crawler

**Defined:** 2026-03-18
**Core Value:** 绕过知乎反爬检测，让爬虫正常工作

## v1 Requirements

### 指纹伪装 (Stealth)

- [x] **STEALTH-01**: 隐藏 navigator.webdriver 属性
- [x] **STEALTH-02**: 移除 Playwright 特有的 JS 属性（__playwright, pwInspect 等）
- [x] **STEALTH-03**: 模拟正常浏览器的 Chrome 属性
- [x] **STEALTH-04**: 修改 User-Agent 为正常浏览器格式

### 集成验证 (Verify)

- [ ] **VERIFY-01**: ZhihuCrawler 集成指纹伪装后能正常访问问答页面
- [ ] **VERIFY-02**: 保持现有功能不变（登录、Cookie、内容爬取）

## Out of Scope

| Feature | Reason |
|---------|--------|
| 其他平台适配 | 本里程碑只针对知乎 |
| 验证码识别 | 知乎主要用二维码登录，验证码场景少 |
| 代理池扩展 | v1.3 已实现，本版本不改动 |
| 行为伪装（鼠标轨迹等） | 先用最小改动验证效果，如需要再加 |

## Traceability

| Requirement | Phase | Status |
|-------------|-------|--------|
