如何从RestTemplate读取响应头？ [英] How do I read the response header from RestTemplate?

问题描述

我使用RestTemplate.postForObject将信息发布到Web服务。除了结果字符串，我还需要响应头中的信息。有没有办法得到这个？

I am posting information to a web service using RestTemplate.postForObject. Besides the result string I need the information in the response header. Is there any way to get this?

RestTemplate template = new RestTemplate();
String result = template.postForObject(url, request, String.class);

推荐答案

好的，我终于明白了。交换方法正是我所需要的。它返回一个包含完整标题的HttpEntity。

Ok, I finally figured it out. The exchange method is exactly what i need. It returns an HttpEntity which contains the full headers.

RestTemplate template = new RestTemplate();
HttpEntity<String> response = template.exchange(url, HttpMethod.POST, request, String.class);

String resultString = response.getBody();
HttpHeaders headers = response.getHeaders();
