csdn 文章批量转换markdown格式下载至本地-阿里云开发者社区

文章目录

1. 背景

最近准备搭建新博客,所以想把所有csdn的文章下载下来，但实在太多，不可能一篇一篇去导出，所以写了一个批量导出脚本，尽管csdn的在线编辑、发布、专栏、自定义模块、模板等比较成熟,但实在没有一点美感,这一点令人比较失望，一开始我比较在意在线编辑速度快，笔记更新方便，检索也还算可以,前几天阿里云开发者社区、infoQ中国社区运营人员相继邀请我去他们平台发布文章，但我更想尝试本地利用Obsidian工具编写笔记试试，并同步github或gitee仓库存储,博客也许会以github page依托利用hexo、Jekyll等工具发布，如果还可以同步notion或云雀就更完美。

2. 功能

通过传入id确立个人用户主页；
创建个人博客目录，专栏目录；
获取专栏URL、名称、篇数量；
依靠专栏URL获取对应的多页文章URL、标题；
遍历文章URL通过cookie获取文章内容并转换markdown格式。

3. 下载

$ git clone https://github.com/Ghostwritten/csdn_to_md.git

4. 配置

chrome浏览器登陆csdn平台，按"F12"找到自己网页cookie,选择部分cookie内容复制至csdn_to_md.py脚本109行。
