把个人博客放在了 netilfy 托管，它给了一个优化建议，可以压缩图片节省带宽。但是每次截图后都要再压缩下图片有点麻烦，于是想着应该可以偷偷懒。目标很明确，截图后图片传到我的 git 仓库 images 目录后，能给我自动压缩，并且上传 COS ，这样我就只用在 markdown 文件里面拼链接就好了。

on run {input, parameters}
	set currentDate to do shell script "date '+%Y%m%d'"
	tell application "System Events"
		repeat with i in input
			set filePath to POSIX path of i
			set fileExtension to name extension of i
			set folderName to do shell script "dirname " & filePath
			if fileExtension is "png" then
				set fileName to name of i
				set AppleScript's text item delimiters to "."
				set baseName to first text item of fileName
				if baseName does not start with currentDate then
					do shell script "/opt/homebrew/bin/pngquant --force --ext .png " & quoted form of filePath
					set newBaseName to currentDate & "_" & baseName
					set newFileName to newBaseName & "." & fileExtension
					set name of i to newFileName
					set newFilePath to folderName & "/" & newFileName
					set uploadCommand to "/opt/homebrew/Caskroom/miniconda/base/bin/coscmd upload " & quoted form of newFilePath & " /"
					do shell script uploadCommand
				end if
			end if
		end repeat
	end tell
end run
