如何将图片从Android应用程序上传到服务器？

Question

我已经开发了一小部分。它可以拍照只是现在不存储。我想从Android应用程序上传图片（使用相机）到服务器。我使用过改造库，网络服务（asp.net）。我怎么能这样做？

清单：

public class UploadPhotoActivity extends AppCompatActivity {
    static final int REQUEST_IMAGE_CAPTURE = 1;

    ImageView imageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_upload_photo);

        imageView=(ImageView)findViewById(R.id.imageView);

    }


    public void SelectPhotoMethod(View view){

        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
            startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
        }

    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
            Bundle extras = data.getExtras();
            Bitmap imageBitmap = (Bitmap) extras.get("data");
            imageView.setImageBitmap(imageBitmap);
        }
    }

}

CODE：

#include <conio.h> // put this somewhere up at the top of the file
void intro()
{
    cout << "Stuff being said " << endl;
    cout << "More stuff being said " << endl;
    cout << "Press 'enter' to continue or 'backspace' to skip...";
    int result = _getch(); // returns number equivalent of a character
    if (result == 8) // 8 is the number equivalent of backspace
        return;
    ...
    code
    ...
}
