用 Python 写了一个PDF转换器,以后再也不用花钱转了
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:
