RestTemplate POST 表单 URL 编码数据给出 400 错误

Question

我正在使用 Spring（版本 2.5.4）RESTTemplate 对 REST 端点 (url) 进行 POST 调用。这是我的代码：

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
    MultiValueMap<String,String> requestBody = new LinkedMultiValueMap<>();
    requestBody.add("token", "abc");
    HttpEntity<MultiValueMap<String,String>> request = new HttpEntity<>(requestBody, headers);
    try
    {       
        ResponseEntity<TokenValidationResponse> responseEntity = restTemplate.exchange(url, HttpMethod.POST, request, TokenValidationResponse.class);   
        TokenValidationResponse response = responseEntity.getBody();
        Boolean isActive = response.getActive();
        if(isActive == null || !isActive) {
            log.info("The token supplied isn't active");
        }
    }
    catch(RestClientException e)
    {
        log.error("An error occurred while posting query to security URI for token validation", e);
    }

我不断遇到 400 错误请求 -

org.springframework.web.client.HttpClientErrorException$BadRequest: 400 Bad Request: [{"error_description":"token parameter is required for the security endpoint.","error":"invalid_request"}]
    at org.springframework.web.client.HttpClientErrorException.create(HttpClientErrorException.java:101)

    at org.springframework.web.client.RestTemplate.execute(RestTemplate.java:711)
    at org.springframework.web.client.RestTemplate.exchange(RestTemplate.java:602)

这是对安全端点 url 给出的要求 - 此端点仅接受 HTTP POST 方法。所需的 Content-Type 值为 application/x-www-form-urlencoded。该端点具有以下参数： token

我可以看到令牌正在传入。当我提供令牌作为正文的一部分时，我能够验证该调用在 POSTMAN 上是否正常工作。我想知道我是否缺少什么？

您需要在标头中指定令牌，例如：

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("Authorization", "Bearer "+accessToken);
