錯誤401，而試圖連接到URL讀取xml

Question

我想通過連接到URL讀取一個XML文件並讀取輸入流，但我有一個錯誤 「java.io.IOException：服務器返回的HTTP響應代碼：401網址：https：// ......」

我通過驗證器類

這裏處理身份驗證的情況下是代碼：

private static InputStream getConnection(String url) { 
     InputStream in = null; 
     try { 

      final String login="cloudtest@arrow.com"; 
      final String password="password"; 

      Authenticator.setDefault(new Authenticator() { 

       @Override 
       protected PasswordAuthentication getPasswordAuthentication() {   
        return new PasswordAuthentication(login, password.toCharArray()); 

       } 
      }); 

      URL myUrl = new URL(url); 


      URLConnection urlConn = myUrl.openConnection(); 
      urlConn.connect(); 
      in = urlConn.getInputStream(); 




     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
     return in; 
    }

試試下面的代碼Source

private static InputStream getConnection(String url) { 
    InputStream in = null; 
    try { 

     final String login="cloudtest@arrow.com"; 
     final String password="password"; 

     Authenticator.setDefault(new Authenticator() { 

      @Override 
      protected PasswordAuthentication getPasswordAuthentication() {   
       return new PasswordAuthentication(login, password.toCharArray()); 

      } 
     }); 

     URL myUrl = new URL(url); 


     URLConnection urlConn = myUrl.openConnection(); 

     urlConn .setDoInput(true); 

     // stuff the Authorization request header 
     byte[] encodedPassword = (login + ":" + password).getBytes(); 
     BASE64Encoder encoder = new BASE64Encoder(); 
     urlConn .setRequestProperty("Authorization", 
         "Basic " + encoder.encode(encodedPassword)); 


     urlConn.connect(); 
     in = urlConn.getInputStream(); 




    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
    return in; 
}
