如何使用字节数组上传图像?

I'm trying to upload image using this code:

我正在尝试用这段代码上传图片:

   private String uploadFile() {
 String responseString = null;

 try {

  HttpClient httpclient = new DefaultHttpClient();
  HttpPost httppost = new HttpPost(Config.FILE_UPLOAD_URL_M);



  Log.i("UploadApp", "upload url: " + Config.FILE_UPLOAD_URL_M);


  AndroidMultiPartEntity entity;
  entity = new AndroidMultiPartEntity(
   new AndroidMultiPartEntity.ProgressListener() {

    @Override
    public void transferred(long num) {
     // publishProgress((int) ((num / (float) totalSize) * 100));
    }
   });

  File sourceFile;
  sourceFile = new File(compressImage(filePath));

  Log.i("UploadApp", "file path: " + filePath);

  // Adding file data to http body

  entity.addPart("f", new FileBody(sourceFile)); //problem is here


  entity.addPart("category", new StringBody("Bill"));
  entity.addPart("description", new StringBody("test single"));
  entity.addPart("file", new StringBody("unknown1"));
  entity.addPart("clientid", new StringBody("4"));



  totalSize = entity.getContentLength();
  httppost.setEntity(entity);

  // Making server call
  HttpResponse response = httpclient.execute(httppost);
  HttpEntity r_entity = response.getEntity();

  int statusCode = response.getStatusLine().getStatusCode();
  if (statusCode == 200) {
   // Server response
   responseString = EntityUtils.toString(r_entity);
  } else {
   responseString = "Error occurred! Http Status Code: " + statusCode;
  }

 } catch (ClientProtocolException e) {
  responseString = e.toString();
  Log.e("UploadApp", "exception: " + responseString);
 } catch (IOException e) {
  responseString = e.toString();
  Log.e("UploadApp", "exception: " + responseString);
 }

 return responseString;

}

I have a web service for uploading image which has 5 parameters and 4 of them are string but one is byte array (byte[] f)

我有一个用于上传图像的web服务，它有5个参数，其中4个是字符串，但一个是字节数组(byte[] f)

main problem: how to convert my source file(image) in byte array to upload the image on server in above code corresponding this web service.

主要问题:如何将我的源文件(图像)转换成字节数组，并在上面对应此web服务的代码中上载到服务器上。

first of all ,from source file you can get absolute path then called upload method

首先，从源文件中可以得到绝对路径，然后称为上传方法

String mCurrentPhotoPath = sourceFile.getAbsolutePath();


private String upload() {
        Bitmap bm = BitmapFactory.decodeFile(mCurrentPhotoPath);
        ByteArrayOutputStream bao = new ByteArrayOutputStream();
        bm.compress(Bitmap.CompressFormat.JPEG, 50, bao);
        byte[] ba = bao.toByteArray();
        return Base64.encodeToString(ba, Base64.DEFAULT);

    }
