您如何在GO（golang）中找到本地主机的FQDN？

Question

How do you find the FQDN of the local host in GO (golang)?

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

Answer 1

By default there is no short way.

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
