用 Python 寫了一個PDF轉換器,以后再也不用花錢轉了
前言
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,博主是不會退縮的,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(基于某網站接口)。
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,通過網站提供的測試接口,我們便可以通過爬蟲模擬的方式實現轉換。
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,這個接口僅用于測試,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。
導入相關庫:
- import time
- import requests

- self.uploadPDF(filepath)
- while True:
- res = self.progress()
- if res == True:
- break
- time.sleep(1)
- self.downloadWord(outpath+filename)
執行主函數:
- if __name__=='__main__':
- pdf2word = PDF2Word()
- pdf2word.convertPDF('001.pdf','')
注意:convertPDF函數有兩個參數,第一個為需要轉換的PDF,第二個參數為轉換后的目錄。
run一下,一鍵入魂,".docx"文件已經躺在了我的目錄中,舒服了~
