又一软件开发商面临破产，背后原因尽然是这个

想必小伙伴都经历过，当你想要把PDF转为WORD时，页面上就会出现四个字甩在你眼前：

不充钱就想白嫖？？想得美~不能这样说，咱们是资源合理利用，今天用python写一个PDF转WORD的小工具（基于某网站接口）。

一、思路分析

网上一搜，你可以发现很多PDF转换的工具，其中不乏在线转换的网站，比如这样的：

那么，通过网站提供的测试接口，我们便可以通过爬虫模拟的方式实现转换。

通过抓包分析，知道这是一个POST请求，接下来用requests库模拟即可。
需要注意的是，这个接口仅用于测试，所以可供转换的页面等都有所限制，如需更完整的功能还请支持原版。

二、我的代码

正所谓一万个coders，就有一万种codes，以下为我的代码，仅供参考。
导入相关库：

import time
import requests

定义PDF2Word类：

class PDF2Word():
    def __init__(self):
        self.machineid = 'ccc052ee5200088b92342303c4ea9399'
        self.token = ''
        self.guid = ''
        self.keytag = ''
    
    def produceToken(self):
        url = 'https://app.xunjiepdf.com/api/producetoken'
        headers = {

        res_json = res.json()
        if res_json['code'] == 10000:
            self.token = res_json['token']
            self.guid = res_json['guid']
            print('成功获取token')

            time.sleep(1)
        self.downloadWord(outpath+filename)

执行主函数：

if __name__=='__main__':    
    pdf2word = PDF2Word()
    pdf2word.convertPDF('001.pdf','')

注意：convertPDF函数有两个参数，第一个为需要转换的PDF，第二个参数为转换后的目录。
run一下，一键入魂，".docx"文件已经躺在了我的目录中，舒服了~
