golang获取本机的mac地址和ip地址

package getNetInfo

import (
	"fmt"
	"net"
)
func GetMac() (macAddrs []string) {
	netInterfaces, err := net.Interfaces()
	if err != nil {
		fmt.Printf("fail to get net interfaces: %vn", err)
		return macAddrs
	}

	for _, netInterface := range netInterfaces {
		macAddr := netInterface.HardwareAddr.String()
		if len(macAddr) == 0 {
			continue
		}
		macAddrs = append(macAddrs, macAddr)
	}
	return macAddrs
}

func GetLocalMac()(mac string){
	// 获取本机的MAC地址
	interfaces, err := net.Interfaces()
	if err != nil {
		panic("Poor soul, here is what you got: " + err.Error())
	}
	for _, inter := range interfaces {
		fmt.Println(inter.Name)
		mac := inter.HardwareAddr //获取本机MAC地址
		fmt.Println("MAC = ", mac)
	}
	return mac
}

func GetIps() (ips []string) {
	interfaceAddr, err := net.InterfaceAddrs()
	if err != nil {
		fmt.Printf("fail to get net interfaces ipAddress: %vn", err)
		return ips
	}

	for _, address := range interfaceAddr {
		ipNet, isVailIpNet := address.(*net.IPNet)
		// 检查ip地址判断是否回环地址
		if isVailIpNet && !ipNet.IP.IsLoopback() {
			if ipNet.IP.To4() != nil {
				ips = append(ips, ipNet.IP.String())
			}
		}
	}
	return ips
}

注：go 语言在获取机器的 mac 地址和 ip 时，windows 和 linux 输出格式不一样，比如 windows 获取的 mac 地址是 8 个字节，而 linux 获取的 mac 是 6 个字节
