您好我使用发送图片和文字到PHP Web服务下code。

Hello I am sending Images and Text to php webservice using following code.

try {


            HttpClient httpClient = new DefaultHttpClient();
            HttpContext localContext = new BasicHttpContext();
            HttpPost httpPost = new HttpPost(URL);

            MultipartEntity entity = new MultipartEntity(
                    HttpMultipartMode.BROWSER_COMPATIBLE);

            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            bitmap.compress(CompressFormat.JPEG, 75, bos);
            byte[] data = bos.toByteArray();

            entity.addPart("files[]",
                    new ByteArrayBody(data, "myImage.jpg"));

            entity.addPart("message0", new StringBody(caption.getText()
                    .toString()));

            httpPost.setEntity(entity);
            HttpResponse response = httpClient.execute(httpPost,
                    localContext);
            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(
                            response.getEntity().getContent(), "UTF-8"));

            String sResponse = reader.readLine();
            return sResponse;
        } catch (Exception e) {
            if (dialog.isShowing())
                dialog.dismiss();
            Toast.makeText(ImageUpload.this, e.getMessage(),
                    Toast.LENGTH_LONG).show();
            Log.e(e.getClass().getName(), e.getMessage(), e);
            return null;
        }

    }

这很好地工作。但是这仅用于一个图像的发送。现在我送5的图像和文字吧。

It work perfectly. But this is for only one image send. Now i send 5 images and text with it.

例： - Image1的 - 文本1           IMAGE2 - 文本2等。

Example:- Image1 - Text1 Image2 - Text2 etc..

所以我很迷惑有关如何存储5图像一招一式，在最终提交点击发送与之相关的图片和文字到服务器。

So I am confuse about how to store 5 images one by one and at final submit click send images and text associated with it to server.

我是从相机获得的图像而已。

I am get image from Camera only.

Intent intent = new Intent();
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);

        o2.inSampleSize = scale;

public static byte[] bitmapToByteArray(Bitmap bitmap) {
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    bitmap.compress(CompressFormat.PNG, 0 /* ignored for PNG */, bos);
    byte[] bitmapdata = bos.toByteArray();
    return bitmapdata;
}

所以，最后我坚持这个请大家帮帮忙。

So Finally i am stuck about this please help.

推荐答案

对于所有细节，请对我的文章一看的点击此处

它相当困难的使用MultipartEntity多个图像发送到服务器。我没有搜索这个，但没有找到任何合适的解决方案的话，我做了我自己的方式去多张图片发送到服务器 ，在这里我送的选择的路径阵列的AsyncTask和AsyncTask的我发图片到服务器的

调用Asysnctask功能 - 新Upload_Multiple.excute（Array_of_Path []））

Calling Asysnctask Function- new Upload_Multiple.excute(Array_of_Path[]))

    Private class Upload_Multiple_img extends AsyncTask<String, Void, String> {

    @Override
    protected void onPreExecute() {
        // TODO Auto-generated method stub
        super.onPreExecute();

    }

    protected String doInBackground(String... paths_array) {



        String data = "";

        for (int i = 0; i < paths_array.length; i++) {

            //  get_Picture_bitmap() returns bitmap by passing path of image 
             //   get_Picture_bitmap() is mentioned below. 
            Bitmap bitmap = get_Picture_bitmap(paths_array[i]);

            ByteArrayOutputStream stream = new ByteArrayOutputStream();

            bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
            InputStream in = new ByteArrayInputStream(stream.toByteArray()); // convert

            DefaultHttpClient httpclient = new DefaultHttpClient();

            String server_funtion_url="...serveraddres"+funtion_at_server"";
            HttpPost httppost = new HttpPost(server_funtion_url); // server

            MultipartEntity reqEntity = new MultipartEntity();

            obj_SP = ImagePicker.this.getSharedPreferences("Eperty", 0);

            String id_prop = obj_SP.getString("new_prop_id", "");

            String Image_Name =
                    + String.valueOf(System.currentTimeMillis()) + ".jpg";
// image is a key which is used at server end to get this 
            reqEntity.addPart("image", Image_Name, in);

            httppost.setEntity(reqEntity);

            HttpResponse response = null;
            try {
                response = httpclient.execute(httppost);
                data = EntityUtils.toString(response.getEntity());
                System.out.println("FFFF== " + data);

            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (ParseException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();

            }

        }

        return data;
    }

    @Override
    protected void onProgressUpdate(Void... values) {

        super.onProgressUpdate(values);
    }

    @Override
    protected void onPostExecute(String result) {

        ConstantData.ToastAlert(ImagePicker.this,
                "Images Uploaded successfully");

    }
}

//）;

//);

有关COM pressing图像和获取的位图我提出以下funtion *

For compressing the images and getting bitmap for i made below funtion*

public Bitmap get_Picture_bitmap(String imagePath) {

long size_file = getFileSize(new File(imagePath));

size_file = (size_file) / 1000;// in Kb now
int ample_size = 1;

if (size_file <= 250) {

    System.out.println("SSSSS1111= " + size_file);
    ample_size = 2;

} else if (size_file > 251 && size_file < 1500) {

    System.out.println("SSSSS2222= " + size_file);
    ample_size = 4;

} else if (size_file >= 1500 && size_file < 3000) {

    System.out.println("SSSSS3333= " + size_file);
    ample_size = 8;

} else if (size_file >= 3000 && size_file <= 4500) {

    System.out.println("SSSSS4444= " + size_file);
    ample_size = 12;

} else if (size_file >= 4500) {

    System.out.println("SSSSS4444= " + size_file);
    ample_size = 16;
}

Bitmap bitmap = null;

BitmapFactory.Options bitoption = new BitmapFactory.Options();
bitoption.inSampleSize = ample_size;

Bitmap bitmapPhoto = BitmapFactory.decodeFile(imagePath, bitoption);

ExifInterface exif = null;
try {
    exif = new ExifInterface(imagePath);
} catch (IOException e) {
    // Auto-generated catch block
    e.printStackTrace();
}
int orientation = exif
        .getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);
Matrix matrix = new Matrix();

if ((orientation == 3)) {
    matrix.postRotate(180);
    bitmap = Bitmap.createBitmap(bitmapPhoto, 0, 0,
            bitmapPhoto.getWidth(), bitmapPhoto.getHeight(), matrix,
            true);

} else if (orientation == 6) {
    matrix.postRotate(90);
    bitmap = Bitmap.createBitmap(bitmapPhoto, 0, 0,
            bitmapPhoto.getWidth(), bitmapPhoto.getHeight(), matrix,
            true);

} else if (orientation == 8) {
    matrix.postRotate(270);
    bitmap = Bitmap.createBitmap(bitmapPhoto, 0, 0,
            bitmapPhoto.getWidth(), bitmapPhoto.getHeight(), matrix,
            true);

} else {
    matrix.postRotate(0);
    bitmap = Bitmap.createBitmap(bitmapPhoto, 0, 0,
            bitmapPhoto.getWidth(), bitmapPhoto.getHeight(), matrix,
            true);

}

return bitmap;
