POST x-www-form-urlencoded

Question

我一直在阅读the following，并试图使用RestTemplate发送带有Spring的POST请求。

HttpHeaders headers = new HttpHeaders();
headers.add("content-type", "application/x-www-form-urlencoded");

final String body = "clipmessage={ bridgeId: \"" + user.getBridgeId() + "\", clipCommand: { url: \"" + setLightState("3") + "\", method: \"PUT\", body: { \"on\": " + state.isOn() + " } } }";
final String url = API_ADDRESS + user.getAccessToken();

HttpEntity<String> entity = new HttpEntity<>(body, headers);

restTemplate.postForEntity(url, entity, String.class);

如果我记录的URL和正文，并发送完全相同的邮递员，它成功。但是，当我从Spring应用程序发送它时，就不会了。

我猜那个特殊的身体必须以某种我不知道的特殊方式被送去？

有谁知道接下来该尝试什么吗？

更新1: --我按建议尝试了MultiValueMap，但也没有成功。

MultiValueMap<String, Object> map = new LinkedMultiValueMap<>();

final String body = "{ bridgeId: \"" + user.getBridgeId() + "\", clipCommand: { url: \"" + setLightState("3") + "\", method: \"PUT\", body: { \"on\": " + state.isOn() + " } } }";

map.add("clipmessage", body);

HttpEntity<String> entity = new HttpEntity<>(body, headers);

我也有同样的情况。在使用以下代码后解决：

  restTemplate = new RestTemplate();

    List<HttpMessageConverter<?>> messageConverters = new ArrayList<>();
    MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
    converter.setSupportedMediaTypes(Collections.singletonList(MediaType.ALL));
    FormHttpMessageConverter formMessageConverter = new FormHttpMessageConverter();
    messageConverters.add(formMessageConverter);
    messageConverters.add(converter);
    restTemplate.setMessageConverters(messageConverters);

参数和头件

...
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
MultiValueMap<String, String> parameters = new LinkedMultiValueMap<>();
        parameters.add("signature", "signature");
        //other parameters
HttpEntity<MultiValueMap<String, String>> requestEntity = new HttpEntity<>(parameters, headers);
ResponseEntity<ResponseMessage> responseEntity = restTemplate.postForEntity(url,  requestEntity, ResponseMessage.class);
ResponseMessage respMsg =responseEntity.getBody();
logMsg.append(",HTTP STATUS=").append(responseEntity.getStatusCode()).append(", RES:").append(marshal(respMsg));
