如何从httpclient获取身份验证方案？

我使用apache httpclient连接到url。每当我收到401错误时，我想知道服务器的身份验证方案？

相似的响应代码得到相似的响应。getStatusLine（）.getStatusCode（）类似地，如何获得哪种身份验证方案？

HttpClient httpclient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpGet httpget = new HttpGet("http://localhost:8080/"); 
HttpResponse response = httpclient.execute(httpget, localContext);

AuthState targetAuthState = (AuthState) localContext.getAttribute(ClientContext.TARGET_AUTH_STATE);
System.out.println("Target auth scope: " + targetAuthState.getAuthScope());
System.out.println("Target auth scheme: " + targetAuthState.getAuthScheme());
