    const [server_ip, setServer_ip] = useState();

    /* 페이지 로드 완료시 호출 이벤트 */
    useEffect( () =>
    {
        var host = window.location.hostname
        setServer_ip('http://' + host + ':8086')

    }, []);

def get_server_ip(request):

    try:
        # weda_port_num = 8090
        # return Response({'port': weda_port_num})

        s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        s.connect(("8.8.8.8", 80))
        print(s.getsockname()[0])

        host = s.getsockname()[0]
