Post Method using Volley not working

android, android-volley, dhc, json

Solution

Solved your problem. Just used `JsonArrayRequest` and passed parameters in `JsonObject` form:

    Map<String, String> params = new HashMap<String, String>();
    params.put("userID", "userid");
    params.put("email","email");
    params.put("passwd", "password");
    JsonArrayRequest request = new JsonArrayRequest(Request.Method.POST, "url", new JSONObject(params),
            new Response.Listener<JSONArray>() {
                @Override
                public void onResponse(JSONArray response) {
                    System.out.println("response -->> " + response.toString());
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    System.out.println("change Pass response -->> " + error.toString());
                }
            });

    request.setRetryPolicy(new

            DefaultRetryPolicy(60000,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));


    Volley.newRequestQueue(activity).add(request);

No need of overriding `getParams()` or `getHeaders()`.

Problem : 1 You were getting response code 500 because the server was accepting the `params` as `JsonObject` and we are trying to feed `String`.

Problem : 2 You were using `JsonObjectRequet` but the response from the server was in `JsonArray` so you need to use `JsonArrayRequest` to accept the response in `JsonArray`

Try and let me know this helps or not :)

Problem

Hi i am using `Volley` for my login page. I need to pass data like this manner ``` { userID : '-988682425884628921', email :'aditya@vyas.com', passwd : '123ss' } ``` I am using POST Method to send data,I already check in DHC, The Api is working fine in DHC and I am getting JSON Response, But when i try with Volley i am not able to get response. and not even any error in my logcat. JAVA code ``` RequestQueue mVolleyQueue = Volley.newRequestQueue(this); CustomRequest req = new CustomRequest(Request.Method.POST,url,null, new Response.Listener<JSONObject>() { @Override public void onResponse(JSONObject response) { Log.v("tag","login response " + response); } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { Log.v("tag","login error response " + error.getMessage()); } }){ @Override public Map<String, String> getParams() throws AuthFailureError { Map<String, String> params = new HashMap<String, String>(); params.put("userID", "-988682425884628921"); params.put("email", "aditya@vyas.com"); params.put("passwd", "123ss"); return params; } @Override public Map<String, String> getHeaders() throws AuthFailureError { Map<String, String> headers = new HashMap<String, String>(); headers.put("Content-Type", "application/json; charset=utf-8"); return headers; } }; mVolleyQueue.add(req); ``` Error ``` 05-28 09:20:14.696 2450-2468/com.android.msahakyan.expandablenavigationdrawer E/tag﹕ parseNetworkError is ! null 05-28 09:20:14.697 2450-2468/com.android.msahakyan.expandablenavigationdrawer E/tag﹕ parseNetworkError status code : 400 05-28 09:20:14.697 2450-2468/com.android.msahakyan.expandablenavigationdrawer E/tag﹕ parseNetworkError message : <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd"> <HTML><HEAD><TITLE>Bad Request</TITLE> <META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD> <BODY><h2>Bad Request - Invalid Header</h2> <hr><p>HTTP Error 400.
