Typora笔记导出html 图片内嵌入html

import os
import base64
import sys
from bs4 import BeautifulSoup

# 环境 有python编译器 本人在pycharm中安装库文件
# 首先在设置中的python解释器中安装Beautifulsoup4库，然后在终端通过镜像源安装lxml库
# python -m pip install lxml -i https://pypi.tuna.tsinghua.edu.cn/simple
# 将保存好的typora_images.py放到html的同级目录下
# 在html目录运行终端后 输入：python typora_images.py "你的笔记.html"

还有一个一劳永逸的办法-通过脚本命令

把脚本文件放到C盘某个文件夹下（自定义）,然后写一个记事本文件，内容如图所示，保存并且更改后缀为cmd；然后在typora设置中找到html导出设置，运行脚本，并且输入命令，就完美啦！
