md图片链接替换

批量替换图片url

自己的笔记都是采用md存储，且图片均为本地的服务器，所以发布博客的时候，需要一个脚本批量处理一下自己的所有md文件

import os,re
from typing import *

img_patten = r'!\[.*?\]\((.*?)\)|<img.*?src=[\'\"](.*?)[\'\"].*?>'
img_match = re.compile(img_patten)
  
def replace_url(md_file_path:str, old:str, new:str) -> str:


    md_data_new = ""
    with open(md_file_path, 'r', encoding='utf-8') as f:
        for each in f.readlines():
            # print(each)
            res = img_match.findall(each)
            if res and len(res) > 0:
                # print(res[0])
                md_data_new += each.replace(old, new)

            else:
                md_data_new += each

    with open(md_file_path, 'w', encoding='utf-8') as f:
        f.write(md_data_new)

    return md_data_new

if ( __name__ == "__main__"):
    target_path = os.path.abspath(r'D:\CPS\MyProject\gitee\cps\NoteBooks\【01】前端相关\JavaScript\实用demo\【canvas】画框拖拽.md')
    search_str = r'https://gitee.com/capsion/markdown-image/raw/master/image/'
    replace_str = r'http://localhost:45462/image/'

    replace_url(target_path, search_str, replace_str)
