我正在尝试从 Android 客户端连接到 RESTful Web 服务。
但是,我总是得到一个HttpClientErrorException: 401 Unauthorized even if provide the correct authorization token in the request header.
提供的网址是正确的。
我也试过这个请求工厂:
template.setRequestFactory(new SimpleClientHttpRequestFactory());
如果我使用具有相同标题和 url 的 Postman for Chorme,我会得到响应。
这是我的代码:
public class PutSomeObjectTask extends AsyncTask<SomeObject, Void, SomeObject>{
@Override
protected SomeObject doInBackground(SomeObject... params) {
SomeObject object = params[0];
String url = ...;
RestTemplate template = new RestTemplate();
template.setRequestFactory(new HttpComponentsClientHttpRequestFactory());
template.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
template.getMessageConverters().add(new FormHttpMessageConverter());
HttpHeaders headers = new HttpHeaders();
headers.add("Content-Type", "application/json");
headers.set("Authorization", AuthUtil.getCurrentUserAuthorization());
HttpEntity<SomeObject> requestEntity = new HttpEntity<SomeObject>(object, headers);
ResponseEntity<SomeObject> responseEntity = template.exchange(url, HttpMethod.PUT, requestEntity, SomeObject.class);
return responseEntity.getBody();
}}
