Spring mvc 谷歌验证码总是失败，没有错误代码

在网页中添加了reCAPTCHA v2 API，但我无法使其正常工作。我已经在html页面中配置了添加验证码的密钥

    <!-- Google reCAPTCHA -->
    <script th:src="@{https://www.google.com/recaptcha/api.js}"></script>

在服务器端（使用Spring）

@RequestMapping（value=“/contact”，method=RequestMethod.POST）
公共可调用的contactQuery（final@modeldattribute（“contact”）@有效的ContactForm ContactForm，
final@RequestParam（“g-recaptcha-response”）字符串captchaResponse，final BindingResult，
最终模型（模型）{
.....
}

然后在另一节课上

@Service
public class ReCaptchaResponseVerfier {

  @Resource
  private Environment environment;

  private static final Logger LOGGER = LoggerFactory.getLogger(ReCaptchaResponseVerfier.class);

  @Async
  public Future<GoogleCaptchaResponseData> isCaptchaResponseValid(String captchaResponse) throws InterruptedException,
      ExecutionException {

    LOGGER.debug(" Validating captcha {}", captchaResponse);

    if (captchaResponse.isEmpty()) {
      GoogleCaptchaResponseData response = new GoogleCaptchaResponseData();
      response.setSuccess(false);
      response.setErrorCodes("The \"I am not a robot\" genie says you didn't verify, please do so.");
      return new AsyncResult<GoogleCaptchaResponseData>(response);
    }

    AsyncRestTemplate restTemplate = new AsyncRestTemplate();

    Map<String, String> uriVariables = new HashMap<String, String>();


    ListenableFuture<ResponseEntity<GoogleCaptchaResponseData>> futureResponse = restTemplate.postForEntity(
        "https://www.google.com/recaptcha/api/siteverify", buildCaptachRequest(captchaResponse),
        GoogleCaptchaResponseData.class);

    GoogleCaptchaResponseData response;
    response = futureResponse.get().getBody();

    return new AsyncResult<GoogleCaptchaResponseData>(response);

  }

  private HttpEntity<GoogleCaptchaRequestData> buildCaptachRequest(String captchaResponse) {
    GoogleCaptchaRequestData request = new GoogleCaptchaRequestData();

    request.setResponse(captchaResponse);
    request.setSecret(environment.getProperty("google.recaptcha.secret"));

    return new HttpEntity<GoogleCaptchaRequestData>(request);
  }

@服务

然而，我总是获得成功：错误响应，即使验证码与页面上的匹配。

问题在于请求，在它提到的发送POST请求的文档上，而在注册密钥的页面上是get request。更改为get request，它现在可以工作了。请提供GoogleCaptCharResponseData sourceIts sorted.p问题出现在文档中。在一个地方发布，在另一个地方获取。获取是正确的方法。我正在尝试实现recaptcha服务器验证。如果你能提供你的代码，这将有助于在这里发布mt

  @RequestMapping(value = "/contact", method = RequestMethod.POST)
  public Callable<String> contactQuery(final @ModelAttribute("contact") @Valid ContactForm contactForm,
      final @RequestParam("g-recaptcha-response") String captchaResponse, final BindingResult bindingResult,
      final Model model) {
   .....
  }
