说明

插件爬虫相当于二次爬虫,二次加工信息,因为大部分插件信息也是从正规网上去获取数据,这次列举helium插件爬虫案例,其他插件爬虫也是类似这个方式.

需求

1、⽤⾕歌浏览器，下载chrome extension：“Helium 10

2、登录helium10 

3、打开

  1. 打开Amazon⾸⻚搜索women clothes https://www.amazon.com/s?

k=women+clothes&crid=F0IYFXRNCJHD&sprefix=women+clothes%2Caps%2C113&ref=n b_sb_noss_1

点击插件，点击Xray，得到如上图的弹窗。

  1. 针对这个表格⾥的每⼀⾏：

（1）记录所有的信息（序号，Product，ASIN，Brand，Price，Sales，Revenue，BSR，

Seller Country/Region, Fees, Active Sellers, Ratings, Reviews, Size Tier, Buy Box, Fulfillment, Dimensions, Weight, Creation Date)等信息

(2) 在Sales，BSR和Reviews旁边如果不是空值的话，会有⼀个图标

点进图标，选All Time：

下载CSV，以每个产品的ASIN命名csv⽂件。

⽐如：

B0CRKQ44NH_sales.csv, B0CRKQ44NH_bsr.csv, B0CRKQ44NH_review.csv

也就是说，针对每个产品，我想要得到⼀个总表和三个分表（Sales，BSR和Review Count）。遍历所有的women clothes产品（我⼀共需要10000个产品）。
