無法從Web服務檢索結果

Question

爲什麼我無法從Web服務獲取結果？當我調試代碼時，它顯示一個異常。

以下代碼用於Web服務請求。

@SuppressWarnings("deprecation") 
protected boolean UserNameAvailability(final String sUserName) 
{ 
    boolean result = false; 

    SoapObject request = new SoapObject(getResources().getString(R.string.targetnamespace), getResources().getString(R.string.usernameavailabilitymethod)); 
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
    envelope.dotNet = true; 

    PropertyInfo piUserName = new PropertyInfo(); 
    piUserName.name = "UserName"; 

    request.addProperty(piUserName, sUserName); 

    HttpTransportSE httpTransport = new HttpTransportSE(getResources().getString(R.string.webserviceurl));     
     try { 
      httpTransport.debug =true; 
      httpTransport.call(getResources().getString(R.string.usernameavailabilitysoapaction), envelope);      
      SoapPrimitive response = (SoapPrimitive)envelope.getResponse(); 
      if (!response.toString().equals("false")) { 
       result = true; 

      } 
      //else 
      //{ 
      // alertBox("User Name already exists.Please enter different username."); 
      // } 

      }catch (Exception exception) { 
       Log.w("UserNameAvailability - RegisterActivity", "Error message is "+exception.getMessage(), exception); 
      } 


      return result; 
}

Answer 1

@Prakash看看下面的代碼，它調用從活動Web服務

public class FirstAppUI extends Activity 
{ 

    private static final String NAMESPACE = "test.org"; 
    private static final String URL = 
    "http://localhost:8080/AndriodBackend/services/listServices/server-config.wsdd";  
    private static final String SOAP_ACTION = "Test"; 
    private static final String METHOD_NAME = "rate"; 

    private static final String[] sampleACTV = new String[] {"android", "iphone", blackberry"}; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     ArrayAdapter<String> arrAdapter = new ArrayAdapter<String> 
     (this, android.R.layout.simple_dropdown_item_1line, sampleACTV); 

     AutoCompleteTextView ACTV = (AutoCompleteTextView)findViewById 
         (R.id.AutoCompleteTextView01); 
     ACTV.setAdapter(arrAdapter); 
     SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);   
     SoapSerializationEnvelope envelope =new SoapSerializationEnvelope(SoapEnvelope.VER11); 

     envelope.setOutputSoapObject(request); 
     HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 

     try { 
       androidHttpTransport.call(SOAP_ACTION, envelope); 
      SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn; 
      ACTV.setHint("Received :" + resultsRequestSOAP.toString()); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 
} 

Answer 2

SoapPrimitive response = (SoapPrimitive)envelope.getResponse(); 

if (!response.toString().equals("false")) 
     result = true; 

嘗試使用它後面可能會解決你的問題。

SoapObject resultRequestSOAP = (SoapObject) envelope.bodyIn; 

String resultString = resultRequestSOAP.getProperty(0).toString(); 

resultString你將得到結果爲真或假。
