分享golang获取本机公网与内网ip地址的几种代码

go获取公网ip代码

package main

import (
	"fmt"
	"io/ioutil"
	"net/http"
)

func main() {
	resp, err := http.Get("https://api.ipify.org")
	if err != nil {
		fmt.Println("Error:", err)
		return
	}
	defer resp.Body.Close()

	body, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		fmt.Println("Error:", err)
		return
	}

	fmt.Println("Public IP Address:", string(body))
}

go获取内网ip地址代码

package main
 
import (
	"fmt"
	"net"
)
 
func main() {
	addrList, err := net.InterfaceAddrs()
	if err != nil {
		panic(err)
	}
	for _, address := range addrList {
		if ipNet, ok := address.(*net.IPNet); ok && !ipNet.IP.IsLoopback() {
			if ipNet.IP.To4() != nil {
				fmt.Println(ipNet.IP.String())
			}
		}
	}
}

package main
 
import (
	"fmt"
	"net"
	"strings"
)
 
func main() {
	conn, err := net.Dial("udp", "8.8.8.8:53")
	if err != nil {
		panic(err)
	}
	addr := conn.LocalAddr().(*net.UDPAddr)
	ip := strings.Split(addr.String(), ":")[0]
	fmt.Println(ip)
