苏宁爬虫 === 苏宁scrapy爬虫,依据搜索引擎实现指定商品爬虫并将商品参数与评论下载入库。 依赖 === scrapy redis mongodb pyqt5 使用 === $ git clone ssh://git@42.123.127.93:10022/bujue/suning.git $ cd suning $ python start.py 分布式爬虫配置 === 在suning/suning/settings.py中 ```python # -*- coding: utf-8 -*- # Scrapy settings for suning project # # For simplicity, this file contains only settings considered important or # commonly used.
