Android Studio Webservice調用「HTTP請求失敗，HTTP狀態：401」未授權

Question

我嘗試將我的Android應用程序連接到Web服務。 我寫了一個新的類和定義的一些變量：

從來就拿到了異步類使用網絡

class GetValueTask extends AsyncTask<ApiConnector,Long,String> { 
    @Override 
    protected String doInBackground(ApiConnector... params) { 
     //wird im Background Thread ausgeführt 
     return params[0].getValue(); 

    } 

    @Override 
    protected void onPostExecute(String s) { 
     //wird im Mainthread ausgeführt 
     MainActivity.this.setText(s); 
    } 
} 

而且我有一個類，我想調用web服務

public class ApiConnector 
{ 
    private static final String SOAP_ACTION ="urn:microsoft-dynamics-schemas/codeunit/AddService:Add"; 
    private static final String METHOD_NAME ="Add"; 
    private static final String NAMESPACE ="urn:microsoft-dynamics-schemas/codeunit/AddService"; 
    private static final String URL ="http://192.168.0.154:9047/DynamicsNAV80/WS/CRONUS%20AG/Codeunit/AddService"; 
    private static final String USERNAME="B.Denger"; 
    private static final String PASSWORD ="TestPW123!"; 



    public String getValue() { 

     SoapObject request = new SoapObject(NAMESPACE,METHOD_NAME); 
     request.addProperty("no","10"); 

     PropertyInfo unamePI = new PropertyInfo(); 
     PropertyInfo passPI = new PropertyInfo(); 
     // Set Username 
     unamePI.setName("username"); 
     // Set Value 
     unamePI.setValue(USERNAME); 
     // Set dataType 
     unamePI.setType(String.class); 
     // Add the property to request object 
     request.addProperty(unamePI); 
     //Set Password 
     passPI.setName("password"); 
     //Set dataType 
     passPI.setValue(PASSWORD); 
     //Set dataType 
     passPI.setType(String.class); 
     //Add the property to request object 
     request.addProperty(passPI); 

     SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
       SoapEnvelope.VER11); 

     soapEnvelope.setOutputSoapObject(request); 

     HttpTransportSE aht= new HttpTransportSE(URL); 

     try { 
      aht.call(SOAP_ACTION, soapEnvelope); 
      SoapPrimitive resultString = (SoapPrimitive) soapEnvelope.getResponse(); 
      return resultString.toString(); 
     }catch(Exception e) { 
      e.printStackTrace(); 
      return "Fail at Call"; 
     } 
    } 
} 

我已經設置了使用許可權在清單文件

<uses-permission android:name="android.permission.INTERNET"/> 

在我的MainActivity做我執行AsynkTask一個按鈕

btn.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      GetValueTask getValueTask = new GetValueTask(); 
      getValueTask.execute(new ApiConnector()); 
     } 
    }); 

執行後，我獲得以下logcat的條目：

W/System.err﹕ org.ksoap2.transport.HttpResponseException: HTTP request failed, HTTP status: 401 

我GOOGLE了一整天了，但我並沒有解決了這個問題。 有沒有人可以幫助我，或者可以給我提示，我必須搜索？

Answer 1

我發現這裏的解決方案：

Android Consuming Dynamics NAV SOAP Web Service

但它沒有在https://jcifs.samba.org/src/與jcif 1.3.17罐子 工作，你可以下載最新版本。

List<HeaderProperty> llstHeadersProperty = new ArrayList<>(); 
llstHeadersProperty.add(new HeaderProperty("Authorization", "Basic " + org.kobjects.base64.Base64.encode("user:password".getBytes()))); 
loHttpTransport.call(sSOAP_ACTION, loEnvelope, llstHeadersProperty); 

完成的任務：

在我的情況下，通過添加此代碼我固定的同樣的問題

private class fnAsyncTask extends AsyncTask<Void, Void, Void> { 

     @Override 
     protected Void doInBackground(Void... params) 
     { 
      //for linear parameter 
      SoapObject loRequest = new SoapObject(sNAMESPACE, sMETHOD_NAME); 
      // adding method property here serially 
//   loRequest.addProperty("CountryName", "france"); 

      SoapSerializationEnvelope loEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
      loEnvelope.implicitTypes = true; 
      loEnvelope.setOutputSoapObject(loRequest); 
      loEnvelope.dotNet = true; 


      HttpTransportSE loHttpTransport = new HttpTransportSE(_sURL); 
      loHttpTransport.debug = true; 
      try 
      { 
       List<HeaderProperty> llstHeadersProperty = new ArrayList<>(); 
       llstHeadersProperty.add(new HeaderProperty("Authorization", "Basic " + org.kobjects.base64.Base64.encode("user:password".getBytes()))); 
       loHttpTransport.call(sSOAP_ACTION, loEnvelope, llstHeadersProperty); 
      } 
      catch (HttpResponseException e) 
      { 
       // TODO Auto-generated catch block 
       Log.e("HTTPLOG", e.getMessage()); 
       e.printStackTrace(); 
      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       Log.e("IOLOG", e.getMessage()); 
       e.printStackTrace(); 
      } catch (XmlPullParserException e) { 
       // TODO Auto-generated catch block 
       Log.e("XMLLOG", e.getMessage()); 
       e.printStackTrace(); 
      } //send request 

      Object result = null; 
      try { 
       result = (Object)loEnvelope.getResponse(); 
       //See output in the console 
       Log.i("RESPONSE",String.valueOf(result)); 
      } catch (SoapFault e) { 
       // TODO Auto-generated catch block 
       Log.e("SOAPLOG", e.getMessage()); 
       e.printStackTrace(); 
      } 
      return null; 
     } 
    }
