Spring RestTemplate POST Request with URL encoded data

Question

I\'m new to Spring and trying to do a rest request with RestTemplate. The Java code should do the same as below curl command:

curl --data \"name=feature&colo

I think the problem is that when you try to send data to server didn't set the content type header which should be one of the two: "application/json" or "application/x-www-form-urlencoded" . In your case is: "application/x-www-form-urlencoded" based on your sample params (name and color). This header means "what type of data my client sends to server".

RestTemplate restTemplate = new RestTemplate();

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
headers.add("PRIVATE-TOKEN", "xyz");

MultiValueMap map = new LinkedMultiValueMap<>();
map.add("name","feature");
map.add("color","#5843AD");

HttpEntity> entity = new HttpEntity<>(map, headers);

ResponseEntity response =
    restTemplate.exchange("https://foo/api/v3/projects/1/labels",
                          HttpMethod.POST,
                          entity,
                          LabelCreationResponse.class);
