從soap web服務中獲取圖像到android應用程序時出錯

Question

我想通過SOAP web服務從服務器獲取圖像到android應用程序中。我在那裏得到一些錯誤。 我想從Web服務接收字節數組中的圖像。 我的代碼是 -

Web服務代碼是 -

@WebMethod(operationName = "GetDiseasePic") 
public byte[] picFromServer(@WebParam(name = "file_name") String filename) { 
    String filePath = "C:/Users/Ashraful/Desktop/layout/icons/" + filename; 
    System.out.println("Sending file: " + filePath); 

    try { 
     File file = new File(filePath); 
     FileInputStream fis = new FileInputStream(file); 
     BufferedInputStream inputStream = new BufferedInputStream(fis); 
     byte[] fileBytes = new byte[(int) file.length()]; 
     inputStream.read(fileBytes); 
     inputStream.close(); 

     return fileBytes; 
    } catch (IOException ex) { 
     System.err.println(ex); 
     throw new WebServiceException(ex); 
    } 

} 

我的Android應用程序是 -

private void imageSelect() { 

final String NAMESPACE_D_PIC = "http://DiseaseInformationWS/"; // target namespace of the Web service available 

final String METHOD_NAME_D_PIC = "GetDiseasePic";// Name of the method in the Webservice file 

final String SOAP_ACTION_D_PIC = "http://DiseaseInformationWS/GetDiseasePic"; // SoapAction that consists of the NAMESPACE+ METHOD_NAME1 

final String URL_D_PIC = "http://"+IpchangeInteface.IPADDRESS+":8080/AshrafThesisWebService/DiseaseWebSer vice?wsdl"; 

    new AsyncTask<String,Void, Bitmap>(){ 
     @Override 
     protected void onPreExecute() { 
      super.onPreExecute(); 
     } 


     @Override 
     protected Bitmap doInBackground(String... params) { 

      SoapObject request_d_pic = new SoapObject(NAMESPACE_D_PIC,METHOD_NAME_D_PIC); 
      request_d_pic.addProperty("file_name",imagefilename); 

      SoapSerializationEnvelope envelop_d_pic = new SoapSerializationEnvelope(SoapEnvelope.VER10); 
      envelop_d_pic.setOutputSoapObject(request_d_pic); 

      HttpTransportSE androidHttpTransport_d_pic = new HttpTransportSE(URL_D_PIC); 

      try { 
       androidHttpTransport_d_pic.call(SOAP_ACTION_D_PIC,envelop_d_pic); 

       SoapObject result_d_pic = (SoapObject) envelop_d_pic.bodyIn; 
       SoapObject result_d_picSP = (SoapObject) envelop_d_pic.bodyIn; 
       String getresult = result_d_pic.toString(); 
       Log.d("IMAGEFILE",getresult); 
       if (getresult!=""){ 
       filebyte = Base64.decode(getresult,Base64.DEFAULT); 
        bitmapImage = BitmapFactory.decodeByteArray(filebyte,0,filebyte.length); 
       } 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } catch (XmlPullParserException e) { 
       e.printStackTrace(); 
      } 
      return bitmapImage; 
     } 
     @Override 
     protected void onPostExecute(Bitmap bitmap) { 
      if(bitmapImage!=null) { 
       diseasePic.setImageBitmap(bitmapImage); 
      } 
     } 

    }.execute(); 
}

請建議我現在要做什麼？

Answer 1

使用此：

filebyte = Base64.decode(getresult, Base64.NO_PADDING);
