只有1kb大小的文件上传到服务器上

Question

我成功从sdcard获取文件，从那里我能够获得输出流，在这里我正在检查它的可用大小，我正在获取大小，现在在使用byteoutputstream上传时，只有1Kb上传到服务器？它可能存在什么问题。 这是我的代码片段，

public String PostData(String path) {
        try {
    SharedPreferences preferences = getSharedPreferences(
    LoginPageActivity.MYPREF, 0);

            HttpClient httpClient = new DefaultHttpClient();
            HttpContext localContext = new BasicHttpContext();

            HttpPost httpPost = new HttpPost(
                    "http://www.idolgreeting.com/app/movie_done.php" /* + postStr */);

            MultipartEntity entity = new MultipartEntity(
                    HttpMultipartMode.BROWSER_COMPATIBLE);

            Log.d("System out", "path is "+path);

            FileInputStream fileInputStream = new FileInputStream(
                    new File(path));


            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            int bytesavailable = fileInputStream.available();
            Log.d("System out", "bytes available "+bytesavailable);
            byte[] buffer = new byte[bytesavailable];
            int test = fileInputStream.read(buffer, 0, bytesavailable);
            Log.d("System out", "test "+test);
//          bos.write(test);
//          
            int maxBufferSize =1000;
             while (test > 0) {
                 bos.write(buffer, 0, bytesavailable);
                 bytesavailable = fileInputStream.available();
                 bytesavailable = Math.min(bytesavailable, maxBufferSize);
                 test= fileInputStream.read(buffer, 0, bytesavailable);
                 Log.d("System out", "test in while loop"+test);
                 }

             byte[] data = bos.toByteArray();
                Log.d("System out", "Length is "+data.length);

            if (imagePath.contains(".mp4")) {
                entity.addPart("_filename", new StringBody("newFile.mp4"));
                Log.d("System out", "MP4 file ");
            } else {
                entity.addPart("_filename", new StringBody("newFile.3gp"));
                Log.d("System out", "3GP file ");
            }
            String[] userID = preferences.getString(LoginPageActivity.USER,
                    null).split("#");
            Log.d("System out", "user id " + userID[0]);
            Log.d("System out", "user id " + userID[1]);

            // entity.addPart("userid", new StringBody(preferences.getString(
            // LoginPageActivity.USER, null)));
            entity.addPart("userid", new StringBody(userID[0]));
            entity.addPart("taskid", new StringBody(bundle.getString("id")));

            entity.addPart("_Get", new StringBody("&android=1"));

            if (imagePath.contains(".mp4")) {
                entity.addPart("uploaded", new ByteArrayBody(data,
                        "newFile.mp4"));
                Log.d("System out", "MP4 file ");
            } else {
                entity.addPart("uploaded", new ByteArrayBody(data,
                        "newFile.3gp"));
                Log.d("System out", "3GP file ");
            }

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

            String sResponse = reader.readLine();
            Log.d("System out", "response " + sResponse);
            if (sResponse.equalsIgnoreCase("true")) {
                dataFlag = true;
            } else {
                dataFlag = false;
            }
            handler.sendEmptyMessage(0);
            return sResponse;
        } catch (Exception e) {
            // if (dialog.isShowing())
            // dialog.dismiss();
            // Toast.makeText(getApplicationContext(),
            // e.getMessage(),
            // Toast.LENGTH_LONG).show();
            Log.e(e.getClass().getName(), e.getMessage(), e);
            dataFlag = false;
            handler.sendEmptyMessage(0);
            return null;
        }
    }
