前言
想必小伙伴都经历过，当你想要把PDF转为WORD时，自己打字赫赫甩在你眼前：
不充钱就想白嫖？？想得美~
然而，博主是不会退缩的，毕竟迎难而上是传统美德。于是，今天的主题出来了：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。
没有错了~思路就是如此的简单明了，今天的主角便是：
https://app.xunjiepdf.com
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：
- #2020最新python学习资源分享：1156465813
- class PDF2Word():
- def __init__(self):
- self.machineid = 'ccc052ee5200088b92342303c4ea9399'
- self.token = ''
- self.guid = ''
- self.keytag = ''

- data = {'machineid':self.machineid}
- res = requests.post(url,headers=headers,data=data)
- res_json = res.json()
- if res_json['code'] == 10000:
- self.token = res_json['token']

- res= requests.post(url,headers=headers,params=params,files=files)
- res_json = res.json()
- if res_json['message'] == '上传成功':
- self.keytag = res_json['keytag']
- print('成功上传PDF')
- return True
- else:
- return False
- def progress(self):
- url = 'https://app.xunjiepdf.com/api/Progress'
- headers = {

- res= requests.post(url,headers=headers,data=data)
- res_json = res.json()
- if res_json['message'] == '处理成功':
- print('PDF处理完成')
- return True
- else:
- print('PDF处理中')
- return False
- def downloadWord(self,output):
- url = 'https://app.xunjiepdf.com/download/fileid/%s'%self.keytag
- res = requests.get(url)
- with open(output,'wb') as f:
- f.write(res.content)
- print('PDF下载成功("%s")'%output)
- def convertPDF(self,filepath,outpath):
- filename = filepath.split('/')[-1]
- filename = filename.split('.')[0]+'.docx'
- self.produceToken()
- self.uploadPDF(filepath)
- while True:
- res = self.progress()
- if res == True:
- break
- 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~
