直接上代码
代码语言：javascript复制func GetClientIp(filter string) (string, error) {
interfaces, err := net.Interfaces()
if err != nil {
return "", err
}
nameIPS := map[string]string{}
names := []string{}
for _, i := range interfaces {
name := i.Name
addrs, err := i.Addrs()
if err != nil {
panic(err)
}
// handle err
for _, addr := range addrs {
var (
ip net.IP
)
switch v := addr.(type) {
case *net.IPNet:
ip = v.IP
case *net.IPAddr:
ip = v.IP
}
if filter == "" || strings.Contains(name, filter) {
names = append(names, name)
nameIPS[name] = ip.String()
}
}
}
sort.Strings(names)
if len(names) == 0 {
return "", errors.New("can not find the client ip address ")
}
logrus.Infof("GetClientIP ips:%v", nameIPS)
return nameIPS[names[0]], nil
}
