为什么使用RestTemplate提取数据时总是得到403？

尝试将“ User-Agent”标头添加到您的请求中。

将您的代码更改为：

try { RestTemplate restTemplate = new RestTemplate(); HttpHeaders headers = new HttpHeaders(); headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON)); headers.add("user-agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36"); HttpEntity<String> entity = new HttpEntity<String>("parameters", headers); Object response = restTemplate.exchange("https://api.hearthstonejson.com/v1/19776/enUS/cards.json", HttpMethod.GET,entity,Object.class); System.out.println(response);        } catch (Exception ex) {ex.printStackTrace();        }
