如何从httpclient获取认证方案？

Question

我使用Apache httpclient连接到一个url.Whenever我得到401错误我想知道服务器的身份验证方案？ 像响应代码越来越像response.getStatusLine（）。getStatusCode（）类似如何得到哪个auth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());
