How do I get the local IP address in Go?

Question

I want to get the computer\'s IP address. I used the code below, but it returns 127.0.0.1.

I want to get the IP address, such as 10.32.10.111

Answer 1

func GetInternalIP() string {
    itf, _ := net.InterfaceByName("enp1s0") //here your interface
    item, _ := itf.Addrs()
    var ip net.IP
    for _, addr := range item {
        switch v := addr.(type) {
        case *net.IPNet:
            if !v.IP.IsLoopback() {
                if v.IP.To4() != nil {//Verify if IP is IPV4
                    ip = v.IP
                }
            }
        }
    }
    if ip != nil {
        return ip.String()
    } else {
        return ""
    }
}
