我正在尝试获取数据，但总是403(Forbidden)与在一起RestTemplate。
403(Forbidden)
RestTemplate
但是当我尝试时org.apache.http.client.HttpClient，一切都很好。我还可以在机器上通过Postman获取数据。
org.apache.http.client.HttpClient
代码很简单，但是我不知道出了什么问题。
public Object get() { try { RestTemplate restTemplate = new RestTemplate(); Object result = restTemplate.getForObject("https://api.hearthstonejson.com/v1/19776/enUS/cards.json", Object.class); return result; } catch (Exception ex) { logger.error(ex.getMessage(), ex); return null; } }
编辑：附加 堆栈跟踪

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(); }
