获取IP

package main

import (
    "fmt"
    "net"
    "os"
)

func main() {

    addrs, err := net.InterfaceAddrs()

    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    for _, address := range addrs {

        // 检查ip地址判断是否回环地址
        if ipnet, ok := address.(*net.IPNet); ok && !ipnet.IP.IsLoopback() {
            if ipnet.IP.To4() != nil {
                fmt.Println(ipnet.IP.String())
            }

        }
    }

}

获取MAC

package main

import (

    "net"

    "fmt"

)

func main() {

  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, inter.HardwareAddr)

  }

}
