L'invio dei file (almeno 11 file) dalla cartella attraverso il servizio web per android app

Question

Ho attaccato nel bel mezzo di questa situazione, per favore darmi una mano.

La mia domanda è che voglio inviare file (Totale 11 file PDF) per android app utilizzando il servizio web.

ho provato con sottostante Codice. principale Classe da cui viene creato il servizio web

public class MultipleFilesImpl implements MultipleFiles {

public FileData[] sendPDFs() {
    FileData fileData = null;
    // List<FileData> filesDetails = new ArrayList<FileData>();
    File fileFolder = new File(
            "C:/eclipse/workspace/AIPWebService/src/pdfs/");
    // File fileTwo = new File(
    // "C:/eclipse/workspace/AIPWebService/src/simple.pdf");

    File sendFiles[] = fileFolder.listFiles();
    // sendFiles[0] = fileOne;
    // sendFiles[1] = fileTwo;

    DataHandler handler = null;
    char[] readLine = null;
    byte[] data = null;
    int offset = 0;
    int numRead = 0;
    InputStream stream = null;
    FileOutputStream outputStream = null;
    FileData[] filesData = null;
    try {
        System.out.println("Web Service Called Successfully");

        for (int i = 0; i < sendFiles.length; i++) {
            handler = new DataHandler(new FileDataSource(sendFiles[i]));
            fileData = new FileData();
            data = new byte[(int) sendFiles[i].length()];
            stream = handler.getInputStream();
            while (offset < data.length
                    && (numRead = stream.read(data, offset, data.length
                            - offset)) >= 0) {
                offset += numRead;
            }
            readLine = Base64Coder.encode(data);
            offset = 0;
            numRead = 0;
            System.out.println("'Reading File............................");
            System.out.println("\n");
            System.out.println(readLine);
            System.out.println("Data Reading Successful");

            fileData.setFileName(sendFiles[i].getName());
            fileData.setFileData(String.valueOf(readLine));

            readLine = null;
            System.out.println("Data from bean " + fileData.getFileData());

            outputStream = new FileOutputStream("D:/"
                    + sendFiles[i].getName());

            outputStream.write(Base64Coder.decode(fileData.getFileData()));

            outputStream.flush();
            outputStream.close();
            stream.close();
            // FileData fileDetails = new FileData();
            // fileDetails = fileData;
            // filesDetails.add(fileData);
            filesData = new FileData[(int) sendFiles[i].length()];
        }
        // return fileData;
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }

    return filesData;
}

}

Anche l'interfaccia MultipleFiles: -

public interface MultipleFiles extends Remote {
    public FileData[] sendPDFs() throws FileNotFoundException, IOException,
            Exception;
}

Ecco, mando un array di fagiolo "file dati" , con proprietà vale a dire. FileData & FileName. FileData- contiene dati dei file in codificato. FileName- nome del file codificato.

The Bean: - (FileData)

public class FileData {
    private String fileName;
    private String fileData;

    public String getFileName() {
        return fileName;
    }

    public void setFileName(String fileName) {
        this.fileName = fileName;
    }

    public String getFileData() {
        return fileData;
    }

    public void setFileData(String string) {
        this.fileData = string;
    }

}

I DDMS Android dà fuori di eccezione di memoria quando ha cercato di seguito il codice & quando ho provato a inviare due file, allora viene creato solo primo file.

public class PDFActivity extends Activity {
    private final String METHOD_NAME = "sendPDFs";
    private final String NAMESPACE = "http://webservice.uks.com/";
    private final String SOAP_ACTION = NAMESPACE + METHOD_NAME;
    private final String URL = "http://192.168.1.123:8080/AIPWebService/services/MultipleFilesImpl";

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        TextView textViewOne = (TextView) findViewById(R.id.textViewOne);

        try {
            SoapObject soapObject = new SoapObject(NAMESPACE, METHOD_NAME);

            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                    SoapEnvelope.VER11);
            envelope.setOutputSoapObject(soapObject);

            textViewOne.setText("Web Service Started");
            AndroidHttpTransport httpTransport = new AndroidHttpTransport(URL);

            httpTransport.call(SOAP_ACTION, envelope);

            // SoapObject result = (SoapObject) envelope.getResponse();
            Object result = envelope.getResponse();
            Log.i("Result", result.toString());
            // String fileName = result.getProperty("fileName").toString();
            // String fileData = result.getProperty("fileData").toString();

            // Log.i("File Name", fileName);
            // Log.i("File Data", fileData);

            // File pdfFile = new File(fileName);


            // FileOutputStream outputStream =
            // openFileOutput(pdfFile.toString(),
            // MODE_PRIVATE);

            // outputStream.write(Base64Coder.decode(fileData));
            Log.i("File", "File Created");
            // textViewTwo.setText(result);
            // Object result = envelope.getResponse();
            // FileOutputStream outputStream = openFileOutput(name, mode)

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

Si prega di aiuto con qualche spiegazione o cambiamenti nel mio codice. Grazie in anticipo.

Answer 1

mi sono preso la soluzione di questo problema.

Il problema principale che ho riscontrato utilizzando kSoap2 API 2.4 versione è che non posso in grado di ottenere oggetto complesso (array di fagioli nel mio caso)

Poi ho cambiato il mio codice da questo (utilizzando ver 2.4): -

try {
            SoapObject soapObject = new SoapObject(NAMESPACE, METHOD_NAME);

            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                    SoapEnvelope.VER11);
            envelope.setOutputSoapObject(soapObject);

            textViewOne.setText("Web Service Started");
            AndroidHttpTransport httpTransport = new AndroidHttpTransport(URL);

            httpTransport.call(SOAP_ACTION, envelope);

            // SoapObject result = (SoapObject) envelope.getResponse();
            Object result = envelope.getResponse();
            Log.i("Result", result.toString());
            // String fileName = result.getProperty("fileName").toString();
            // String fileData = result.getProperty("fileData").toString();

            // Log.i("File Name", fileName);
            // Log.i("File Data", fileData);

            // File pdfFile = new File(fileName);


            // FileOutputStream outputStream =
            // openFileOutput(pdfFile.toString(),
            // MODE_PRIVATE);

            // outputStream.write(Base64Coder.decode(fileData));
            Log.i("File", "File Created");
            // textViewTwo.setText(result);
            // Object result = envelope.getResponse();
            // FileOutputStream outputStream = openFileOutput(name, mode)

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

a questo codice (utilizzando ver 2.5.1): -

    try {
        SoapObject soapObject = new SoapObject(NAMESPACE, METHOD_NAME);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);

        envelope.setOutputSoapObject(soapObject);

        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        androidHttpTransport.call(SOAP_ACTION, envelope);

        SoapObject result = (SoapObject) envelope.bodyIn;

        for (int i = 0; i < result.getPropertyCount(); i++) {
            SoapObject object = (SoapObject) result.getProperty(i);

            Log.i("File Data", object.getProperty("fileData").toString());
            Log.i("File Name", object.getProperty("fileName").toString());

            pdfFiles = new File(object.getProperty("fileName").toString());
            outputStream = openFileOutput(pdfFiles.toString(), MODE_PRIVATE);
            outputStream.write(Base64Coder.decode(object.getProperty(
                    "fileData").toString()));
        }

        outputStream.flush();
        outputStream.close();
        Log.d("File Creation Message", "Files Created Succesfully");
    } catch (SoapFault fault) {
        fault.printStackTrace();
    } catch (XmlPullParserException e) {
        e.printStackTrace();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (outputStream != null) {
            outputStream = null;
        }
    }

Quindi ho avuto soluzione.
