RestTemplate的使用

String url = Config.XXX_BASE_URL + "/userlevel?inviterId=" + invit1;
String restInfo = MessageFormat.format("url:{0}, inviterId:{1}", url, invit1);
UtilFunctions.log.info("UserController#register call rest api info, " + restInfo);

HttpHeaders requestHeaders = new HttpHeaders();
List<String> cookieList = UtilFunctions.getCookieList(request);
requestHeaders.put("Cookie", cookieList);
HttpEntity<String> requestEntity = new HttpEntity<String>(null, requestHeaders);
restTemplate.exchange(url, HttpMethod.GET, requestEntity, JSONObject.class).getBody();

public static List<String> getCookieList(HttpServletRequest request) {
    List<String> cookieList = new ArrayList<>();
    
    Cookie[] cookies = request.getCookies();
    if (cookies == null || cookies.length == 0) {
        return cookieList;
    }

    for (Cookie cookie : cookies) {
        cookieList.add(cookie.getName() + "=" + cookie.getValue());
    }
    
    return cookieList;
}
