Android: posting to Laravel with Volley doesn't work

Question

I'm using google Volley library to handle my application networking.

My backend is an apache server with Laravel 4. When i'm trying to make a POST request using JsonObjectRequest I'm getting an empty $_POST array.

I was able to solve it using the method described here: Volley JsonObjectRequest Post request not working

but it seems like a solution for simple cases where the object is not very complicated. Also, i'd like to use Gson and a custom GsonRequest, but it gives the same problem.

Seems odd to me that php and especially Laravel don't know how to deal with JSON requests as this is a REST framework, am I missing something? Is there a better way to solve it?

Well, apparently the solution is very simple, just needed to dig deeper into documentation :)

http://laravel.com/docs/requests

and specifically this NOTE:

Some JavaScript libraries such as Backbone may send input to the application as JSON. You may access this data via Input::get like normal.

This is how I solved it. Below is the custom class I created extending class of volley. Parameters is provided as Map

public class CustomJsonRequest extends Request {

Map<String, String> params;       
private Response.Listener listener; 

public CustomJsonRequest(int requestMethod, String url, Map<String, String> params,
                      Response.Listener responseListener, Response.ErrorListener errorListener) {

    super(requestMethod, url, errorListener);
    this.params = params;
    this.listener = responseListener;
}

@Override
protected void deliverResponse(Object response) {
    listener.onResponse(response); 

}

@Override
public Map<String, String> getParams() throws AuthFailureError {
         return params;
}

@Override
protected Response parseNetworkResponse(NetworkResponse response) {
    try {
        String jsonString = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
        return Response.success(new JSONObject(jsonString),
        HttpHeaderParser.parseCacheHeaders(response));
    } catch (UnsupportedEncodingException e) {
        return Response.error(new ParseError(e));
    } catch (JSONException je) {
        return Response.error(new ParseError(je));
    }
}

}

and you can provide pamas as

Map<String, String> params = new HashMap<String, String>();
  params.put("email", email.getText().toString());
  params.put("password", password.getText().toString());

using this you will be able to use GET or POST verbs in your api.

this is only good for simple cases where the object is flat, but what if you have a complex data structure you want to send? — Tomer, Jan 21 '14 at 20:33
I have come across such situation but i think that can be solved by using $_POST['userinfo']['email']. — user98239820, Jan 22 '14 at 04:25
