### Requirements Coverage
|
||
|
||
| Requirement | Source Plan | Description | Status | Evidence |
|
||
| --- | --- | --- | --- | --- |
|
||
| AUTH-01 | 07-01 | 用户可通过二维码扫码登录知乎 | SATISFIED | ZhihuLogin.login_by_qrcode() 完整实现，测试通过 |
|
||
| AUTH-02 | 07-02 | 用户可手动设置 Cookie 进行认证 | SATISFIED | parse_json_cookies() + --import-cookie 参数 |
|
||
| AUTH-03 | 07-02 | Cookie 自动持久化到本地文件，下次自动复用 | SATISFIED | CookieManager.save_cookie/load_cookie + get_settings 缓存清除 |
|
||
| AUTH-04 | 07-03 | Cookie 过期时自动检测并提示重新登录 | SATISFIED | validate_cookie() + CookieValidationResult |
|
||
|
||
### Anti-Patterns Found
|
||
|
||
| File | Line | Pattern | Severity | Impact |
|
||
| --- | --- | --- | --- | --- |
|
||
| (none) | - | - | - | auth 模块无 TODO/FIXME/placeholder |
|
||
|
||
**Note:** 在 `kb_workflow/pipeline/platforms/bilibili.py` 中存在 TODO 注释，但这不在阶段7范围内。
|
||
|
||
### Human Verification Required
|
||
|
||
虽然所有自动化测试通过，以下场景需要人工验证：
|
||
|
||
#### 1. 二维码扫码登录端到端测试
|
||
|
||
**Test:** 运行 `python3 kb-workflow/kb_workflow.py login`
|
||
**Expected:**
|
||
- 二维码图片生成在 `~/work/intermediate/zhihu_qrcode_*.png`
|
||
- 使用知乎 APP 扫码后命令返回 `{"success": true, "cookie_str": "..."}`
|
||
- `~/.kb_env` 文件包含 `ZHIHU_COOKIE="..."` 行
|
||
|
||
**Why human:** 需要真实的知乎 APP 扫码，无法自动化测试
|
||
|
||
#### 2. Cookie 状态检查
|
||
|
||
**Test:** 运行 `python3 kb-workflow/kb_workflow.py login --status`
|
||
**Expected:**
|
||
- 有效 Cookie: 返回 `{"valid": true, "username": "...", "user_id": "..."}`
|
||
- 过期 Cookie: 返回 `{"valid": false, "reason": "Cookie expired"}`
|
||
|
||
**Why human:** 需要真实有效的 Cookie 才能验证 API 返回
|
||
|
||
#### 3. JSON Cookie 导入
|
||
|
||
**Test:** 使用 Chrome Cookie Editor 导出 cookies.json，运行 `python3 kb-workflow/kb_workflow.py login --import-cookie cookies.json`
|
||
**Expected:** Cookie 正确导入并保存到 ~/.kb_env
|
||
|
||
**Why human:** 需要真实的 Chrome Cookie Editor 导出文件
|
||
|
||

### Summary
|
||
|
||
**Phase 7 (登录认证体系) 验证通过:**
|
||
|
||
1. **AUTH-01 二维码扫码登录** - ZhihuLogin 类实现完整，支持多选择器回退、可配置超时、二维码保存
|
||
2. **AUTH-02 手动 Cookie 导入** - parse_json_cookies 支持 Chrome Cookie Editor 格式，域名过滤
|
||
3. **AUTH-03 Cookie 持久化** - CookieManager 保存到 ~/.kb_env，权限 600，缓存清除
|
||
4. **AUTH-04 Cookie 过期检测** - validate_cookie 通过 /api/v4/me 验证，返回详细状态
|
||
|
||
所有 33 个单元测试通过，关键连接点验证通过，无阻塞性 anti-pattern。
|
||
|
||
**Ready for Phase 8 (内容爬取实现)**
