org.springframework.web.client.HttpClientRoreXception$BadRequest:400错误请求

Question

对于下面的代码，我收到了一个400错误的请求

public String saveQuoteCall(String jsonObjectStr) {

            try {
                preparePostHttpEntity(jsonObjectStr);
                response = restTemplate.exchange(CREATE_QUOTE_URL, HttpMethod.POST, entity, String.class);
                log.info("Response : " + response.getStatusCode());
                if (response.getStatusCode() == HttpStatus.OK) {
                    return response.getBody();
                }
            } catch (Exception e) {
                log.error("Error in saveQuoteCall : ", e);
            }
            return "No Data";
        }

        private void preparePostHttpEntity(String sendingStr) {

            try {
                headers = new HttpHeaders();
                log.info("request in checkCDBalance preparePostHttpEntity: " + sendingStr);
                headers.set(HttpHeaders.WWW_AUTHENTICATE, ServiceSecurity.getHeaderValue());
                // log.info("request in checkCDBalance preparePostHttpEntity:
                // "+HttpHeaders.WWW_AUTHENTICATE);
                headers.setAccept(Arrays.asList(new MediaType[] { MediaType.TEXT_PLAIN }));
                headers.setContentType(MediaType.TEXT_PLAIN);
                entity = new HttpEntity<String>(sendingStr, headers);
                log.info("entity value: " + entity);
                restTemplate = new RestTemplate();
            } catch (Exception e) {
                log.error("Error in preparePostHttpEntity : ", e);
            }
        }

下面是stacktrace

400 Bad Request response status code表示服务器不能或不会处理该请求，原因是被认为是客户端错误（例如，错误的请求语法、无效的请求消息帧或欺骗性的请求路由）

由于请求中的某种错误，您得到了400响应。

如果希望了解更多信息，可以在DefaultResponseErrorHandler::HandleError方法中调试收到的响应（由ClientHtPresponse对象表示）。您应该能够通过查看响应的主体来检测问题。
