如何使用Go语言实现远程执行命令

func main() { 
 session, err := connect("root", "olordjesus", "dockers.iotalabs.io", 2210)
 if err != nil {
 log.Fatal(err)
 }
 defer session.Close()

 fd := int(os.Stdin.Fd())
 oldState, err := terminal.MakeRaw(fd)
 if err != nil {
 panic(err)
 }
 defer terminal.Restore(fd, oldState)

 // excute command
 session.Stdout = os.Stdout
 session.Stderr = os.Stderr
 session.Stdin = os.Stdin

 termWidth, termHeight, err := terminal.GetSize(fd)
 if err != nil {
 panic(err)
 }

 // Set up terminal modes
 modes := ssh.TerminalModes{
 ssh.ECHO:  1, // enable echoing
 ssh.TTY_OP_ISPEED: 14400, // input speed = 14.4kbaud
 ssh.TTY_OP_OSPEED: 14400, // output speed = 14.4kbaud
 }

 // Request pseudo terminal
 if err := session.RequestPty("xterm-256color", termHeight, termWidth, modes); err != nil {
 log.Fatal(err)
 }

 session.Run("top")
}
