MalformedChallengeException：身份驗證的挑戰是空的

我想繞過Android的基本身份驗證，並陷入了這個錯誤。請參閱下面我的代碼：MalformedChallengeException：身份驗證的挑戰是空的

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(); 
}

這是我得到的錯誤..

試過這些，仍然沒有發現認證挑戰。 – user142020a 2014-09-29 04:41:43

如果用戶名和密碼正確，它正在工作，但在憑證錯誤時引發異常。 – user142020a 2014-09-29 05:13:22

替換：

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

有了：

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