#爬取梨视频 热门视频

我感觉视频类网站，反爬措施都挺严厉的
网上教程未必能与时俱进

./是什么路径

抉择啊

1. for li in li_list:
   
2.     detail_url = 'https://www.pearvideo.com/' + li.xpath('./div/a/@href')[0]
   
3.     new_name = li.xpath('./div/a/div[2]/div[@class="vervideo-name"]/text()')[0] + '.mp4' #保存的文件名错了,改为.mp4
   
4.     #对详情页的url发起请求

./是什么路径

当前文件所在目录，一般Windows PowerShell支持这么写，但更推荐用反斜杠.\，cmd会报错，Python不知道可不可以

我总得懂点什么

./是什么路径

一个点  。  是指代当前路径

mp4的命名问题，有非法字符。
