如何使用Spring的RestTemplate發送自定義對象和頁眉

Question

我想使用RestTemplate將自定義對象和自定義頁眉作爲POST請求發送到URL。以下是我正在使用的代碼;

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); 

但它給了我以下錯誤;

請指教我需要做些什麼改變。

Answer 1

對不起，我在授權標題中犯了一個錯誤，它必須是這樣的;

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

該代碼工作正常，再次抱歉。
