Question

我只是想发出一个简单的REST请求，如下所示

    @Test
    public void retcall() {

        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.valueOf(MediaType.APPLICATION_JSON_VALUE));
        headers.set(HttpHeaders.ACCEPT, "*/*");
        headers.set("X-IBM-Client-id", CLIENT_ID);
        headers.set(HEADER_AUTHORIZATION_KEY, "Bearer " + tokenInfo);
        HttpEntity<String> entity = new HttpEntity<>(headers);
        String url = VALIDATION_HTTP_PREFIX + SCF_SB + VALIDATION_HTTP_SUFFIX;
        RestTemplate restTemplate = new RestTemplate();
        List<? extends HttpMessageConverter<?>> httpMessageConverters = Collections.singletonList(new MappingJackson2HttpMessageConverter());
        restTemplate.setMessageConverters((List<HttpMessageConverter<?>>) httpMessageConverters);
        log.info("checking authentication {}", entity);
        ResponseEntity<String> exchange = restTemplate.exchange(url, HttpMethod.GET, entity, String.class);
        System.out.println(exchange);

    }

但是我得到了

我已经尝试了所有方法，例如Invalid mime type in spring rest template?中所述，但仍然无法正常工作...

尽管此“未知”内容类型来自响应；有了邮递员，我就能得到身体的反应...

您有什么想法吗？

谢谢！

尝试更换

headers.setContentType(MediaType.valueOf(MediaType.APPLICATION_JSON_VALUE));

使用

headers.setContentType(MediaType.APPLICATION_JSON);

Spring Rest模板中未知的MIME类型？
