Spring restTemplate获取原始的json字符串

Question

如何从spring rest模板中获取原始json字符串？我试过跟随代码,但它返回我没有引号的json导致其他问题,我怎么能得到json原样.

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

Answer 1

你甚至不需要ResponseEntitys!只要使用getForObject了String.class,如:

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

System.out.println(response);

它将打印如下:

{
  "origin": "1.2.3.4"
}
