Spring RestTemplate获取原始JSON字符串 [英] Spring restTemplate get raw json string

问题描述

如何从Spring Rest模板获取原始json字符串?我已经尝试过以下代码，但它会返回不带引号的json，这会导致其他问题，我该如何按原样获取json.

How can I get the raw json string from spring rest template? I have tried following code but it returns me json without quotes which causes other issues, how can i get the json as is.

ResponseEntity<Object> response  = restTemplate.getForEntity(url, Object.class);
String json = response.getBody().toString();

推荐答案

您甚至不需要ResponseEntity！只需使用

You don't even need ResponseEntitys! Just use getForObject with a String.class like:

final RestTemplate restTemplate = new RestTemplate();
final String response = restTemplate.getForObject("https://httpbin.org/ip", String.class);

System.out.println(response);

它将打印类似的内容:

{
  "origin": "1.2.3.4"
}
