# 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)
|
||||
|
||||
- [x] **VERIFY-01**: ZhihuCrawler 集成指纹伪装后能正常访问问答页面
|
||||
- [x] **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 |
|
||||
|-------------|-------|--------|

|
||||
|
||||
### Phase 11: Stealth Fingerprinting (指纹伪装)

|
||||
**Depends on**: Phase 10
|
||||
**Requirements**: STEALTH-01, STEALTH-02, STEALTH-03, STEALTH-04, VERIFY-01, VERIFY-02
|
||||
**Success Criteria** (what must be TRUE):
|
||||
1. ZhihuCrawler 访问问答页面时不再被 40362 错误拦截
|
||||
2. 爬虫的 navigator.webdriver 属性对知乎不可见
|
||||
3. Playwright 特有的 JS 属性（__playwright, pwInspect 等）被移除
|
||||
4. 现有功能（登录、Cookie 持久化、内容爬取）保持正常工作
|
||||
**Plans**: 2 plans (all complete)
|
||||
|
||||
Plans:
|
||||
- [x] 11-01-PLAN.md — 创建 StealthConfig 模块和单元测试

|
||||
|
||||
**Key Decisions:**
|
||||
- 使用 playwright-stealth 库进行指纹伪装
|
||||
- stealth_config=None 表示默认启用 stealth (向后兼容)
|
||||
- launch 时添加 --disable-blink-features=AutomationControlled 参数
