L'envoi des fichiers (au moins 11 fichiers) à partir du dossier par le service Web pour Android app

Question

Je coincé au milieu de cette situation, S'il vous plaît aidez-moi.

Ma question est que je veux envoyer des fichiers (Total 11 fichiers PDF) à l'application Android en utilisant le service Web.

Je l'ai essayé avec le code ci-dessous. classe principale à partir de laquelle le service Web est créé

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;
}

}

L'interface aussi MultipleFiles: -

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

Ici, je suis l'envoi d'un tableau de haricot « Fichier de données » , à savoir ayant des propriétés. FileData & FileName. FileData- contient des données de fichier dans codée. FileName- nom de fichier codé.

Le 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;
    }

}

L'androïde DDMS donne à exception de mémoire lorsque essayé ci-dessous le code et quand j'ai essayé d'envoyer deux fichiers alors que premier fichier est créé.

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();
        }
    }
}

S'il vous plaît aider quelques explications ou des changements dans mon code. Merci d'avance.

Answer 1

Moi-même a la solution de cette question.

Le problème majeur que je fait face à l'aide kSoap2 api version 2.4 est que je ne peux pas en mesure d'obtenir l'objet complexe (tableau de haricots dans mon cas)

Alors j'ai changé mon code de ce (en utilisant 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();
        }

à ce code (en utilisant 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;
        }
    }

D'où je suis arrivé solution.
