使用其他模板时遇到错误请求

标签: java spring rest http spring-boot

尝试使用RestTemplate时,我一直收到错误的请求错误。我尝试了getForObject()exchange()两种方法,但都没有工作,所以我做错了吗?

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.add("Accept", MediaType.APPLICATION_JSON.toString());

MultiValueMap<String, String> requestBody = new LinkedMultiValueMap<>();
requestBody.add("param1", "value1");
requestBody.add("param2", "true");

RestTemplate restTemplate = new RestTemplate();
return restTemplate.exchange(API_URI, HttpMethod.POST,
                    new HttpEntity<>(requestBody, headers), String.class);

堆栈跟踪:(隐藏的api名称)

答案 0 :(得分:0)

您可以尝试删除Accept标头,因为它是默认的json

headers.add("Accept", MediaType.APPLICATION_JSON.toString());

OR

尝试添加接受标头,如下所示

headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));

并检查你提到的作为String.class的响应类型对象是什么,请交叉检查

您可以尝试更改

    headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
MultiValueMap<String, Object> requestBody = new LinkedMultiValueMap<>();
        requestBody.add("param1", "value1");
        requestBody.add("param2", true);Try this?
