Typora 官方文档中清楚的介绍了怎么自定义使用图片上传工具

You could config a custom command to upload images, using tools that is not listed in above options, or event write your own tools / scripts. Typora will append all images that needs to be uploaded after the custom command you filled.
Then, Typora will fetch image urls from the last N lines of the standard output of your custom command. (N is the number of images to upload).
For example, if you write a tool upload-image.sh, then you can input [some path]/upload-image.sh in the command filed. Typora will call [some path]/upload-image.sh “image-path-1” “image-path-2” to upload two images located in image-path-1 and image-path-2. Then the command may return something like:
Upload Success:
http://remote-image-1.png
http://remote-image-2.png
Then Typora will get the two remote image url from the output, and replace the original local images used in the Markdown document.
You could click the “Test Uploader” button to verify your custom commands.

效果：

upload.sh

#!/bin/bash

base_url="apiurl/1.1/files/"
lc_id="api-id"
lc_key="api-key"

i=0
for file in "$@"
do
result[((i++))]=$(curl -X POST \
  -H "X-LC-Id: $lc_id" \
  -H "X-LC-Key: $lc_key" \
  -H "Content-Type: image/${file##*.}" \
  --data-binary "@$1"  \
  $base_url${file##*/})

done

parse_json(){
        value=`echo $1 | sed 's/.*"url":\([^,}]*\).*/\1/'`
        echo $value | sed 's/\"//g'
}

echo "Upload Success:"
for url in "${result[@]}"
do
        output=$(parse_json $url "url")
        echo $output | sed 's/\\//g'
done
