public String[] getUsernameAndTokenFromCookies(HttpServletRequest request){
    String[] usernameAndToken = new String[2];

    Cookie[] cookies = request.getCookies();
    String usernameInCookie = null;
    String tokenInCookie = null;

    if( cookies != null ){
        for (int i = 0; i < cookies.length; i++){
            Cookie cookie = cookies[i];
            if (cookie.getName().equals("username")){
                usernameInCookie = cookie.getValue();
            }
            if (cookie.getName().equals("token")){
                tokenInCookie = cookie.getValue();
            }
        }
    }

    usernameAndToken[0] = usernameInCookie;
    usernameAndToken[1] = tokenInCookie;

    return usernameAndToken;
