## 1、获取mac地址和ip地址，需要使用golang的net模块，下面通过`net模块`获取本机MAC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: %v\n", err)
    		return macAddrs
    	}
    
    	for _, netInterface := range netInterfaces { 
    		macAddr := netInterface.HardwareAddr.String()
    		if len(macAddr) == 0 { 
    			continue
    		}
    		macAddrs = append(macAddrs, macAddr)
    	}
    	return macAddrs
    }

## 2、直接获取本机的MAC地址 ##

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
    }

## 3、获取IP地址 ##

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