Android Java - 如何获取真实文件（图像和视频）路径并使用AsyncHttp上传到服务器

Question

我有一个项目，我需要允许用户上传图像和视频到服务器...目前用户可以选择图像和视频..但我不知道如何获得真正的文件路径然后上传使用AsyncHttp Post ...

这是我在下面选择图片的代码：

 pphoto.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Intent intent = new Intent();
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);

        }


    });

这是我的onactivityresult代码

protected void onActivityResult(int requestCode, int resultCode,
                                Intent imageReturnedIntent){

    super.onActivityResult(requestCode, resultCode, imageReturnedIntent);

    switch(requestCode) {
        case PICK_IMAGE_REQUEST: // Do your stuff here...
            if (resultCode == RESULT_OK) {

                final String path = imageReturnedIntent.getData().getPath();


                final File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath());




                Uri selectedData = imageReturnedIntent.getData();


                final Button up = (Button) findViewById(R.id.up);

                final ImageView etPhoto = (ImageView) findViewById(R.id.imgg);



                String[] filePathColumn = {MediaStore.Images.Media.DATA};

                Cursor cursor = getContentResolver().query(
                        selectedData, filePathColumn, null, null, null);
                cursor.moveToFirst();

                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                final String filePath = cursor.getString(columnIndex);
                cursor.close();


                final Bitmap dImage = BitmapFactory.decodeFile(filePath);


                etPhoto.setImageURI(selectedData);

然后，如果我想发布到服务器...这是我正在使用的代码但不工作......

AsyncHttpClient client = new AsyncHttpClient();
                        RequestParams params = new RequestParams();
                        params.put("token", "token");
                        try {
                            params.put("photo", file);
                        } catch (FileNotFoundException e) {
                            e.printStackTrace();
                        }
                        client.post("http://10.205.165.237/Android/uploadimages.php", params, new AsyncHttpResponseHandler() {

                            @Override
                            public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
                                System.out.println("statusCode " + statusCode);//statusCode 200
                            }

                            @Override
                            public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {

                            }
                        });

现在我的问题是我不知道如何获取用于上传的真实文件路径，我不确定AsyncHttp帖子是否正确cos我已经尝试了PHP代码我将文件发送到html表单它工作正常....请有人知道如何去做...？您的贡献将受到高度赞赏。
