• 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
  }
