volley how to parse params to JsonObjectRequest getParams does not work

Question

As an old version of volley.jar. I pass params by following method:

@Override
public byte[] getBody() {
    if (params != null && params.size() > 0) {
        return encodeParameters(params, getParamsEncoding());
    }
    return null;
}                

But I need to update volley, and find that this method(encodeParameters()) was changed to private.

I also found that to override the method of getParams(), which did not work for me. the Method getBody of JsonObjectRequest is as following:

public byte[] getBody() {
    try {
        return mRequestBody == null ? null : mRequestBody.getBytes(PROTOCOL_CHARSET);
    } catch (UnsupportedEncodingException uee) {
        VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s",
            mRequestBody, PROTOCOL_CHARSET);
        return null;
    }
}

getParams() would never be called. so I cannot pass the params now.

I also tried to pass the params in the construct method which has JsonObject param, but it did not work either.

hope I'm understanding you correctly.

an easier way to pass params with volley would be:

    String url = "some/url";

    Map<String, Object> jsonParams = new HashMap<>();
    jsonParams.put("someparam", getSomeParamObject());

    JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url, new JSONObject(jsonParams),
            new Response.Listener<JSONObject>()
            {
                @Override
                public void onResponse(JSONObject response)
                {
                 //do your magic...
                }
            }

for the encoding issue, see if this SO Question helps.

Hope this Helps.
