Question

我将多个数据发送到服务器，如视频，图像和文本在我的情况下，当我上传所有数据时，它将被上传但是，在我的应用程序中，某些数据不是必需的所以它将是空白或NUll。当我向Volly发送此类请求（空值或空白）时，它会从错误列表器中向我提供Toast。在下面的代码（AdvertiseImage2ImageBitmap）将为null，我从错误列表器获取Toast 如何解决这个问题。我正在寻找2天。

private void uploadAdNewUser() {
    String[] parts = Duration.split("\\:"); // escape .
    Video_Min = parts[0];
    Video_Sec = parts[1];
    Utils.pdialogMk(AddAdvertisePublicity.this);
    VolleyMultipartRequest volleyMultipartRequest = new VolleyMultipartRequest(Request.Method.POST, AppConstants.MainUrl + AppConstants.AddAdvertise,
            new Response.Listener<NetworkResponse>() {
                @Override
                public void onResponse(NetworkResponse response) {
                    try {
                        JSONObject obj = new JSONObject(new String(response.data));
                        Utils.pdialog_dismissMk();
                        if (obj.getString(AppConstants.flag).equals("true")) {
                            Utils.ShowToast(obj.getString(AppConstants.message));
                            startActivity(new Intent(AddAdvertisePublicity.this, MainActivity.class));

    //adding the request to volley
    Volley.newRequestQueue(this).add(volleyMultipartRequest);
    volleyMultipartRequest.setRetryPolicy(mRetryPolicy);

以下是对getByteData（）方法的一些更改。如下所列。

@Override
    protected Map<String, DataPart> getByteData() {
        Map<String, DataPart> params = new HashMap<>();
        long AdImage1 = System.currentTimeMillis();
        long AdImage2 = System.currentTimeMillis() + 1;
        long VideoName = System.currentTimeMillis() + 3;
        if (AdvertiseImage1ImageBitmap != null) {
            params.put(AppConstants.advertise_image1, new DataPart(AdImage1 + ".png", getFileDataFromDrawable(AdvertiseImage1ImageBitmap)));
        }
        if (AdvertiseImage2ImageBitmap != null) {
            params.put(AppConstants.advertise_image2, new DataPart(AdImage2 + ".jpg", getFileDataFromDrawable(AdvertiseImage2ImageBitmap)));
        }
        if (Vidbuffer != null) {
            params.put(AppConstants.video, new DataPart(VideoName + ".mp4", Vidbuffer));
        }
        return params;
    }

如何在多部分请求中通过Volly-Library向空间参数发送空参数？
