python还能写PDF转换器?

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

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

                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了
