scrapy抓取淘宝商品详情页，读取url随机强制302，跳转到h5.taobao。

Question

1. 使用scrapy+redis从一定量的淘宝详情页url获取商品详情

2. 已设置user-agent，已传入cookie，已设置proxy-ip

3. 获取url，response.status有时是200，有时是302，随机改变

4. 1000个url，成功获取商品信息大概有400多

5. 是否为cookie未传入成功，还是proxy-ip不稳定？或者其他原因。请帮忙分析，谢谢！

6. 报错Traceback：

Answer 1

1. 已找到异常原因，导入user-agent里面有mobile端的ua，删除之后，就没问题了

2. 自己更新了一个2017最新的ua_list(pc端)给大家：https://github.com/lovebaicai...
