Spring의 RestTemplate을 사용하여 사용자 지정 개체 및 헤더를 보내는 방법

Question

RestTemplate을 사용하여 URL에 POST 요청으로 사용자 지정 개체와 사용자 지정 헤더를 보내려고합니다. 다음은 내가 사용하고있는 코드입니다.

MultiValueMap<String, String> headers = new LinkedMultiValueMap<String, String>(); 
    headers.add("Authorization: key=", SERVER_KEY); 
    headers.add("Content-Type", "application/json"); 

    RestTemplate restTemplate = new RestTemplate(); 
    restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter()); 

    CustomDataModel customDataModel = new CustomDataModel(); 
    customDataModel.setTitle(message); 
    customDataModel.setBody(rowId); 

    CustomNotificationModel customNotificationModel = new CustomNotificationModel(); 
    customNotificationModel.setRegistration_ids(list); 
    customNotificationModel.setPriority("high"); 
    customNotificationModel.setData(customDataModel); 

    HttpEntity<CustomNotificationModel> entity = new HttpEntity<CustomNotificationModel>(customNotificationModel, headers); 

    restTemplate.postForLocation(REST_SERVICE_URI, entity); 

하지만 다음과 같은 오류가 발생합니다.

변경해야 할 사항을 알려주십시오.

Answer 1

죄송합니다. 인증 헤더를 잘못 작성했습니다. 다음과 같이 작성해야합니다.

headers.add("Authorization", "key=" + SERVER_KEY); 

코드가 잘 작동합니다. 다시 한번 죄송합니다.
