天猫和唯品会类似，商品信息都是通过json传递

遇到一些难点，分步骤梳理

第一步还是找到天猫的评论js

在点开评论之后，可以看到有个list_detail文件是我们要找的js文件。里面有我们所需要的评论

接下来就是常规的导入requests包、BeautifulSoup包、json包

天猫一样有反爬虫机制，我们需要先登陆天猫帐号。

并加入headers模拟正常浏览器访问

最后找到我们需要的json开头和结尾

这里易错点是ends，不要把反括号加进去了。

最后由于天猫的评论有可能会有买家不晒图或者多张晒图，所以加入try

最后放上代码

import requests
from bs4 import BeautifulSoup
import json
from urllib.parse import quote

结果可以正常导出这一页的评论和买家的晒图（最多5张）。之后只要分类进行保存即可

通过这种方式，可以快速把同行的好评晒图快速的复制保存。不用手动一张一张保存。效率大幅提升。

接下来再更新如何把评论翻页处理完，实现一次性把所有评论全部爬取。
