前言
某個夜深人靜的夜晚,夜微涼風微揚,月光照進我的書房~
當我打開檔案夾以回顧往事之余,驚現許多看似雜亂的無聊代碼,我拍腿正坐,一個想法油然而生:“生活已然很無聊,不如再無聊些叭”,
于是,我決定開一個專題,便稱之為kimol君的無聊小發明,
妙…啊~~~
想必小伙伴都經歷過,當你想要把PDF轉為WORD時,自己打字赫赫甩在你眼前:

不充錢就想白嫖?? 想得美~
然而,kimol君是不會退縮的,畢竟迎難而上是傳統美德,于是,今天的主題出來了:用python寫一個PDF轉WORD的小工具(基于某網站介面),
一、思路分析
網上一搜,你可以發現很多PDF轉換的工具,其中不乏在線轉換的網站,比如這樣的:

那么,通過網站提供的測驗介面,我們便可以通過爬蟲模擬的方式實作轉換,
沒有錯了~思路就是如此的簡單明了,今天的主角便是:
https://app.xunjiepdf.com
通過抓包分析,知道這是一個POST請求,接下來用requests庫模擬即可,
需要注意的是,這個介面僅用于測驗,所以可供轉換的頁面等都有所限制,如需更完整的功能還請支持原版,
二、我的代碼
正所謂一萬個coders,就有一萬種codes,以下為我的代碼,僅供參考,
匯入相關庫:
import time
import requests
定義PDF2Word類:
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 = {

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('成功獲取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'

'Content-Type': 'application/pdf',
'Origin': 'https://app.xunjiepdf.com',
'Connection': 'keep-alive',

res= requests.post(url,headers=headers,params=params,files=files)
res_json = res.json()
if res_json['message'] == '上傳成功':
self.keytag = res_json['keytag']
print('成功上傳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',

'X-Requested-With': 'XMLHttpRequest',

'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'] == '處理成功':
print('PDF處理完成')
return True
else:
print('PDF處理中')
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下載成功("%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)
執行主函式:
if __name__=='__main__':
pdf2word = PDF2Word()
pdf2word.convertPDF('001.pdf','')
注意:convertPDF函式有兩個引數,第一個為需要轉換的PDF,第二個引數為轉換后的目錄,
run一下,一鍵入魂,".docx"檔案已經躺在了我的目錄中,舒服了~

寫在最后
最后,感謝各位大大的耐心閱讀,咋們下次再會~
創作不易,大俠請留步… 動起可愛的雙手,來個贊再走唄 (???←?)
