hn.jinye.cn 卷烟订货平台数据采集脚本 v2（青龙面板专用）
|
||
|
||
功能：
|
||
- 采集卷烟目录全部 378 条产品数据
|
||
- 列表页 DOM 解析（浏览器翻页）+ 详情页 API 调用（纯 HTTP，极快）
|
||
- 支持增量更新、断点续传
|
||
- 输出 Excel 与旧脚本（jinye_scraper.py）格式兼容
|
||
|
||
青龙环境依赖安装:
|
||
pip install playwright openpyxl httpx
|
||
playwright install chromium
|
||
|
||
用法:
|
||
python hn_jinye_scraper.py # 增量更新（默认）
|
||
python hn_jinye_scraper.py --quick # 快速模式（仅列表页，跳过详情API）
|
||
python hn_jinye_scraper.py --template ./模板.xlsx # 指定模板
|
||
python hn_jinye_scraper.py --delay 0.3 # 设置翻页/API间隔
|
||
python hn_jinye_scraper.py --no-images # 跳过图片下载
|
||
python hn_jinye_scraper.py --api-workers 10 # API并发线程数
|
||
python hn_jinye_scraper.py --use-edge # 使用系统Edge浏览器（本地测试用）
