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:

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 = {
'User-Agent': 'Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:76.0) Gecko/20100101 Firefox/76.0',
'Accept': 'application/json, text/javascript, */*; q=0.01',
'Accept-Language': 'zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2',
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
'X-Requested-With': 'XMLHttpRequest',
'Origin': 'https://app.xunjiepdf.com',
'Connection': 'keep-alive',
'Referer': 'https://app.xunjiepdf.com/pdf2word/',}
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']
self.guid = res_json['guid']
print('成功获取token')
return True
else:
return False

def uploadPDF(self,filepath):
filename = filepath.split('/')[-1]
files = {'file': open(filepath,'rb')}
url = 'https://app.xunjiepdf.com/api/Upload'
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:76.0) Gecko/20100101 Firefox/76.0',
'Accept': '*/*',
'Accept-Language': 'zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2',
'Content-Type': 'application/pdf',
'Origin': 'https://app.xunjiepdf.com',
'Connection': 'keep-alive',
'Referer': 'https://app.xunjiepdf.com/pdf2word/',}
params = (
('tasktype', 'pdf2word'),
('phonenumber', ''),
('loginkey', ''),
('machineid', self.machineid),
('token', self.token),
('limitsize', '2048'),
('pdfname', filename),
('queuekey', self.guid),
('uploadtime', ''),
('filecount', '1'),
('fileindex', '1'),
('pagerange', 'all'),
('picturequality', ''),
('outputfileextension', 'docx'),
('picturerotate', '0,undefined'),
('filesequence', '0,undefined'),
('filepwd', ''),
('iconsize', ''),
('picturetoonepdf', ''),
('isshare', '0'),
('softname', 'pdfonlineconverter'),
('softversion', 'V5.0'),
('validpagescount', '20'),
('limituse', '1'),
('filespwdlist', ''),
('fileCountwater', '1'),
('languagefrom', ''),
('languageto', ''),
('cadverchose', ''),
('pictureforecolor', ''),
('picturebackcolor', ''),
('id', 'WU_FILE_1'),
('name', filename),
('type', 'application/pdf'),
('lastModifiedDate', ''),
('size', ''),)
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 = {
'User-Agent': 'Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:76.0) Gecko/20100101 Firefox/76.0',
'Accept': 'text/plain, */*; q=0.01',
'Accept-Language': 'zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2',
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
'X-Requested-With': 'XMLHttpRequest',
'Origin': 'https://app.xunjiepdf.com',
'Connection': 'keep-alive',
'Referer': 'https://app.xunjiepdf.com/pdf2word/',}
data = {
'tasktag': self.keytag,
'phonenumber': '',
'loginkey': '',
'limituse': '1'}
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~
