您如何找到本地主机的FQDN? [英] How do you find the FQDN of the local host?

问题描述

如何在Go中找到本地主机的FQDN?

How do you find the FQDN of the local host in Go?

顺便说一句:net.LookupAddr()在Windows上不起作用.所以这不是一个选择.

BTW: net.LookupAddr() doesn't work on Windows. So that's not an option.

推荐答案

默认情况下，没有捷径可做.

By default there is no short way.

os.Hostname()默认不提供完全合格的域名

os.Hostname() doesn't provide the Fully Qualified Domain Name by default.

cmd := exec.Command("/bin/hostname", "-f")
var out bytes.Buffer
cmd.Stdout = &out
err := cmd.Run()
if err != nil {
    log.Errorf(err)
}
fqdn := out.String()
fqdn = fqdn[:len(fqdn)-1] // removing EOL
