机构官网 URL 补全器 v7.0.0 (url_completer.py)
|
||
|
||
为 registry 中无官网（website 为空）的机构批量补全 URL：
|
||
1. 多引擎搜索 "{机构名} 官网"（百度/搜狗/DDG HTML，走 search_engine 统一入口）
|
||
2. 候选过滤：剔除搜索引擎自身/聚合平台（天眼查/企查查/百科/门户频道等）
|
||
与一切政务类域名（脱敏红线，绝不入库）
|
||
3. 可达性验证：GET 状态 < 400 才回填
|
||
4. 增量落盘：每 N 家写一次 registry + 进度文件（data/url_completion_progress.json），
|
||
支持断点续跑（--resume，默认开）
|
||
|
||
用法：
|
||
python scripts/url_completer.py --limit 50 # 补 50 家
|
||
python scripts/url_completer.py --type 期货公司 # 只补某类型
|
||
python scripts/url_completer.py --report # 看缺 URL 统计
