如何使用 RestTemplate 传递 headers？

Question

在我的方法中，我最初使用 RestTemplate postForObject 方法向端点 post 请求。现在我必须添加默认 OAuth 令牌并将其作为 Post 请求传递。有什么方法可以通过使用 postForObject?

作为 POST 请求的一部分同时传递 request 和 Default Header

下面我用的初始postForObject

 String result = restTemplate.postForObject(url, request, String.class);

我正在寻找类似下面的内容

             restTemplate.exchange(url,HttpMethod.POST,getEntity(),String.class );

这是我的代码

    private final String url;
        private final MarkBuild header;

    public DataImpl(@Qualifier(OAuth) MarkBuild header,RestTemplate restTemplate) {
               this.restTemplate= restTemplate;
                this.header = header;
    }

    public void postJson(Set<String> results){
        try {
             Map<String, String> requestBody = new HashMap<>();
             requestBody.put("news", "data");
              JSONObject jsonObject = new JSONObject(requestBody);

             HttpEntity<String> request = new HttpEntity<String>(jsonObject.toString(), null);

            String result = restTemplate.postForObject(url, request, String.class);
        } 
    }

下面是 getHttpEntity 我想通过 Post 请求


    private HttpEntity getHttpEntity(Set <String>results) {
          return new HttpEntity<>( null, getHttpHeaders() );
    }

    private HttpHeaders getHttpHeaders() {
        return header.build();
    }
}

Is there any way I can pass both request as well as Default Header as part of POST request by using postForObject?

是的，有办法做到这一点，我可以举一个基本的例子：

HttpHeaders lHttpHeaders = new HttpHeaders();
lHttpHeaders.setContentType( MediaType.APPLICATION_JSON );//or whatever it's in your case
String payload="<PAYLOAD HERE>"
try
{
    String lResponseJson = mRestTemplate.postForObject( url, new HttpEntity<Object>( payload, lHttpHeaders ), String.class);
    return lResponseJson;
}
catch( Exception lExcp )
{
    logger.error( lExcp.getMessage(), lExcp );
}

如果这不起作用请告诉我！！
