本文介绍了一种使用Python爬虫从百度文库下载PPT的方法，通过解析网页获取图片链接并保存到本地文件夹，同时利用VB宏脚本批量创建PPT页面并导入图片。

今天帮媳妇儿做一个PPT，无奈百度文库没有积分。偶然用一次，如今互联网上哪哪都要充值还得是包月，很烦。
分两步：

爬取文库的PPT，输出图片，放到一个文件夹中
PPT开发者模式，写一个宏文件，批量创建PPT页并按顺序导入图片

下面是代码：
Python版爬虫脚本，输入参数是URL。PPT版的已经经过测试验证，其他的应该原理都一样，需要的自行验证。
VB版PPT宏脚本，文件夹路径需要自己指定。

import requests
import re
import argparse
import json
import os

    doc_id = re.findall('view/(.*).html', url)[0]
    html = requests.get(url).text
    lists = re.findall('(https.*?0.json.*?)\\\\x22}', html)
    lenth = (len(lists) // 2)
    NewLists = lists[:lenth]
    for i in range(len(NewLists)):
        NewLists[i] = NewLists[i].replace('\\', '')
        txts = requests.get(NewLists[i]).text
        txtlists = re.findall('"c":"(.*?)".*?"y":(.*?),', txts)
