Go Command Agent - 技术栈

很多时候大家需要去某个服务器上去执行一段命令或者上传/下载一个文件，这个命令还可能是时间比较久的，不想一直等在那里，特别是内网里面，不要复杂的认证，比如CICD里面，这时候大家可以使用这个command agent部署在server上，从而通过rest api来轻松的执行命令。

github：GodQ/go-rest-agent (github.com)

这个agent是使用Go编写的，提供了多种OS/CPU的版本，可以拿来即用。

部署命令：

nohup ./agent_linux_amd64 5000 &

下面是这个agent的5个api：
