RestTemplate使用情况

Question

我试图使用resttemplate来生成put。出于某种原因，我无法重现我使用curl创建的put，该代码可以毫无问题地运行。

下面是我的curl调用成功并返回200：

curl https://www.exampe.com \
  -X PUT \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <bearer-token>" \
  -v \
  -d '{"json":"object"}'

boolean result = false; 
String url = "https://www.example.com";
String json = "{\"json\":\"object\"}";

RestTemplate rest = new RestTemplate();

HttpHeaders headers = new HttpHeaders();
headers.add("Content-Type", "application/json");
headers.add("Authorization", String.format("Bearer %s", authToken));

HttpEntity<String> requestEntity = new HttpEntity<String>(json, headers);
ResponseEntity<String> responseEntity = 
        rest.exchange(url, HttpMethod.PUT, requestEntity, String.class);

HttpStatus status = responseEntity.getStatusCode();

Answer 1

啊，真蠢。缺少的部分是accept标头。显然，curl默认添加accept:*/*。可能是endpoint实现需要正确的accept标头。增加这一行就解决了问题：

headers.add("Accept", "*/*");
