MalformedChallengeException：身份验证的挑战是空的

Question

我想绕过Android的基本身份验证，并陷入了这个错误。 请参阅下面我的代码：

HttpUriRequest request = new HttpGet(url); 
String credentials = "username" + ":" + "password"; 
String base64EncodedCredentials = Base64.encodeToString(credentials.getBytes(), Base64.NO_WRAP); 
request.addHeader("Authorization", "Basic " + base64EncodedCredentials); 

HttpClient httpclient = new DefaultHttpClient(); 

try { 
HttpResponse response = httpclient.execute(request); 
Log.d("Login: Response", EntityUtils.toString(response.getEntity())); 
} catch (IOException e) { 
e.printStackTrace(); 
} 

这是我得到的错误..

替换：

request.addHeader("Authorization", "Basic " + base64EncodedCredentials); 

有了：

request.addHeader("Authorization", "Basic "+Base64.encodeToString("rat#1:rat".getBytes(),Base64.NO_WRAP));
