源代码：https://github.com/Ckend/taobao_scrapy
语言：Python3
爬取平台：手机端
PS：在当前文件夹下先创建好result文件夹
源代码包含两个Python文件，get_items.py 用于通过关键词获得商品基本信息，包括商品名称、店铺、销量、评论数、图片、优惠、出货地、原价等等。输出格式为.csv文件。
另一个Python文件: get_review_cloud.py 用于通过userID和itemID (从get_items.py中获得这两个信息) 获得某商品的评论云。输出.csv文件。
源代码很简单，十几行，逻辑如下：
1. 访问接口(f=urllib.request.urlopen(url))
2. 读取源代码并解码为utf-8然后转化为json
3. 写入至.csv文件。
以下给出get_items.py的内容，其他的请见GitHub，如果你有收获，请帮忙点个Star~
