Typora编写markdown插入本地图片时自动上传图片到博客园

Typora编写markdown插入图片时自动上传图片到博客园

1.登录博客园后获取cookie值

Cookie的key为`.Cnblogs.AspNetCore.Cookies`,仅此一个就足够了

2.上脚本代码

# upload_image2cnblogs.py
# 支持本地图片及网络图片

import requests
import sys

ip_middle_octet = r"(?:.(?:1?d{1,2}|2[0-4]d|25[0-5]))"
ip_last_octet = r"(?:.(?:0|[1-9]d?|1dd|2[0-4]d|25[0-5]))"

regex = re.compile(  # noqa: W605

3.设置Typora

• 上传服务选择Custom Command

• 命令为python(或其他虚拟环境python解释器路径) py脚本绝对路径，Typora会自动往脚本里传参图片的绝对路径，参数的长度和参数的个数都是不确定的

• 图片上传完成后，Typora 需要你按指定格式在控制台输出图片的 URL 给它

  Upload Success:
  https://stormbuf.coding.net/p/piccoding/d/piccoding/git/raw/master/typora-icon2.png
  

  第一行一定要是 Upload Success:，然后第二个非空行开始，一行一个图片 URL

• 插入图片时：这个选项可以选择上传图片或者选择无特殊操作

  • 选择上传图片时当你选择插入本地图片时会自动把图片上传到博客园并返回上传后的图片地址
  • 选择无特殊操作时，当你选择插入本地图片时会自动提示你进行其他操作，比如上传图片等

• 上传图片时,如有报错,请仔细查看报错信息,如无明显报错信息,请检查Cookie是否已失效.

4.总结

当前脚本是上传图片到博客园做图床，目前只适用于当前博客园的上传图片接口，脚本是否过期，自行判断。此脚本只是做了个引子，读者照葫芦画瓢也可以上传其它OSS或者图床等。
