Gin：获取本机IP，获取访问IP

 获取本机IP

func GetLocalIP() []string {
  var ipStr []string
  netInterfaces, err := net.Interfaces()
  if err != nil {
      fmt.Println("net.Interfaces error:", err.Error())
      return ipStr
  }

  for i := 0; i < len(netInterfaces); i++ {
      if (netInterfaces[i].Flags & net.FlagUp) != 0 {
          addrs, _ := netInterfaces[i].Addrs()
          for _, address := range addrs {
              if ipnet, ok := address.(*net.IPNet); ok && !ipnet.IP.IsLoopback() {
                  //获取IPv6
                  /*if ipnet.IP.To16() != nil {
                      fmt.Println(ipnet.IP.String())
                      ipStr = append(ipStr, ipnet.IP.String())

                  }*/
                  //获取IPv4
                  if ipnet.IP.To4() != nil {
                      fmt.Println(ipnet.IP.String())
                      ipStr = append(ipStr, ipnet.IP.String())

                  }
              }
          }
      }
  }
  return ipStr

}

 获取访问IP

  //获取ip
func GetRequestIP(c *gin.Context)string{
    reqIP := c.ClientIP()
  if reqIP == "::1" {
      reqIP = "127.0.0.1"
  }
    return reqIP
}
