	"os/exec"
	"strings"
)

func main() {
	s := GetLocalNetDeviceNames()
	fmt.Println(s)
}

func GetLocalNetDeviceNames() []string {
	baseNicPath := "/sys/class/net/"
	cmd := exec.Command("ls", baseNicPath)
	buf, _ := cmd.Output()
	output := string(buf)
	str := ""
	for _, device := range strings.Split(output, "\n") {
		if len(device) > 1 {
			if device != "lo" {
				str += device+"|"
			}
		}
	}
	return strings.Split(str[:len(str)-1],"|")
}

输出
