关于go build ./文件压缩的步骤
首先需要在build的时候加上参数
//这样就能使项目降低
go build -ldflags '-w -s' ./
如果还需要更小，则需要安装upx 安装完成后配置到系统环境变量中。cmd运行upx
C:\Users\pan>upx

然后执行upx需要压缩的exe文件或linux文件（upx兼容多系统）
upx XXX.exe
需要给go exe加图标
创建一个XXX.rc文件 内容为IDI_ICON1 ICON "XXX.ico"
使用windres.exe生成syso文件
windres -o XXX.syso XXX.rc
然后再go build ./
