Senden Sie die Dateien (mindestens 11 Dateien) vom Ordner über den Webdienst an Android App aus

Question

Ich habe in dieser Situation geblieben, bitte hilf mir.

Meine Frage ist, dass ich Dateien (insgesamt 11 PDF -Dateien) an Android -App über den Webdienst senden möchte.

Ich habe es mit dem folgenden Code ausprobiert.Hauptklasse, aus der Webdienst erstellt wird

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;
}

}

Auch die Schnittstelle mehrere Dateien:-

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

Hier sende ich eine Array von Bean "Dateidaten", mit Eigenschaften, nämlich. Fileedata & Dateiname. Fieledata enthält Dateidaten in codiert. Dateiname Dateiname.

Die Bohne:- (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;
    }

}

Die Android -DDMS geben die Speicherausnahme aus, wenn sie unter dem Code ausprobiert werden und als ich versucht habe, zwei Dateien zu senden, wird nur die erste Datei erstellt.

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();
        }
    }
}

Bitte helfen Sie mit einer Erklärung oder Änderungen in meinem Code. Vielen Dank im Voraus.

Answer 1

Ich habe die Lösung dieser Frage bekommen.

Das Hauptproblem, mit dem ich mit der KSOAP2 -API 2.4 -Version konfrontiert war, ist, dass ich kein komplexes Objekt erhalten kann (in meinem Fall eine Bean -Array).

Dann habe ich meinen Code daraus geändert (mit 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();
        }

zu diesem Code (mit 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;
        }
    }

Daher bekam ich Lösung.
