Android volley put request not working with name value pairs

Question

In my application i need to post some parameters to the server by using HttpPut method. so for that i checked with the Basic Authentication technique and succeed to get the same in that way. But when i tried to implement the same with Json Volley i am unable to get the result. Every time it is throwing the server error.

Here is my code to pass the Basic Authentication using Asynctask::

@Override
        protected Void doInBackground( String... params )
        {
            // TODO Auto-generated method stub

            try
            {
                HttpPut request = new HttpPut( params[0] );

                Log.d("debug", "Posting URL" + params[0]);

                String creds = String.format( "%s:%s",
                        "user123",
                        "abcd" );

                String auth = "Basic " + Base64.encodeToString( creds.getBytes(),
                        Base64.NO_WRAP );

                request.setHeader( "Authorization",
                        auth );

                List<NameValuePair> urlParameters = new ArrayList<NameValuePair>();
                urlParameters.add(new BasicNameValuePair("id", "409"));
                urlParameters.add(new BasicNameValuePair("parent_id", "0"));
                urlParameters.add(new BasicNameValuePair("content", "I am android developer"));
                urlParameters.add(new BasicNameValuePair("email", "[email protected]"));
                urlParameters.add(new BasicNameValuePair("username", "King Of Masses"));

                request.setEntity(new UrlEncodedFormEntity(urlParameters));

                DefaultHttpClient httpClient = new DefaultHttpClient();
                HttpResponse response = httpClient.execute( request );
                HttpEntity Entity = response.getEntity();
                String jsondata = EntityUtils.toString( Entity );

                Log.d( "debug",
                        "Response Code::  " + response.getStatusLine().getStatusCode() );

                Log.d( "debug",
                        "Json Data in Asynctask:: " + jsondata );

                JSONObject ljsJsonObject=new JSONObject(jsondata);

                Log.d( "debug",
                        "Json Object Data:: " + ljsJsonObject.toString() );

            }
            catch( ClientProtocolException e )
            {
                Log.d( "debug",
                        "Exception" + e.toString() );
                e.printStackTrace();
            }
            catch( IOException e )
            {

                Log.d( "debug",
                        "Exception" + e.toString() );
                e.printStackTrace();
            }
            catch( Exception e )
            {

                e.printStackTrace();
            }
            return null;
        } 

So in this above way i got the result what i expected.. but i am unable to implement the same with VolleyJson.. Can any one guide me how to achieve this.. I tried too many ways like ( getBody(), getParams()) but unfortunately nothing worked for me..

Any help would be highly appreciate.. Thank you

Answer 1

After few trails i finally got the solution for my question and i got the same result with VollyJson too.. Here i am posting the solution. It may be helpful for some one in future.

Here is my VollyJson call::

String postUrl="http://xxxxxxxxx/xxxx";

final List<NameValuePair> params = new ArrayList<NameValuePair>();


                params.add(new BasicNameValuePair("id", "409"));
                params.add(new BasicNameValuePair("parent_id", "0"));
                params.add(new BasicNameValuePair("content", "I am android developer"));
                params.add(new BasicNameValuePair("email", "[email protected]"));
                params.add(new BasicNameValuePair("username", "King Of Masses"));


        StringRequest stringReq = new StringRequest( Method.PUT,
                                                     postUrl,
                                                     new Response.Listener<String>()
                                                     {

                                                         @Override
                                                         public void onResponse( String arg0 )
                                                         {

                                                             mListener.notifyResponse( arg0 );

                                                         }

                                                             trimErrorMessage( arg0,

Answer 2

There's a bug in Android Volley in which it doesn't read the getParas key value pairs.

You have 2 options

1. Use StringRequest and then parse this into JSON (I use this!)- something like this - and then override the getParams method as you would do normally.

   RequestQueue queue = Volley.newRequestQueue(this);
   String url ="http://www.google.com";
   
   // Request a string response from the provided URL.
   StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
           new Response.Listener<String>() {
   @Override
   public void onResponse(String response) {
       JSONObject obj = new JSONObject(response);
       //Now you can manipulate/store your JSON
   
   }
       }, new Response.ErrorListener() {
     @Override
        public void onErrorResponse(VolleyError error) {
          mTextView.setText("That didn't work!");
       }
     })
    {  
   
    protected Map<string, string=""> getParams() throws      com.android.volley.AuthFailureError {  
       Map<string, string=""> params = new HashMap<string, string="">();  
       params.put("param1", num1);  
       params.put("param2", num2);  
       return params;  
       };  
   };  
              // Add the request to the RequestQueue.
              queue.add(stringRequest);
   

2. Use a Custom Request object - Similar to something like this

   CustomRequest request = new CustomRequest(Method.POST, URL, null, new Response.Listener<JSONObject>() {
       @Override
      public void onResponse(JSONObject response) {
          Toast.makeText(getActivity(), response.toString(),  Toast.LENGTH_SHORT).show();
        }
    }, new Response.ErrorListener() {
        @Override
       public void onErrorResponse(VolleyError error) {
          Toast.makeText(getActivity(), "Error.", Toast.LENGTH_SHORT).show();
      }
      }) {
        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
         Map<String, String> params = new HashMap<String, String>();
          params.put("id", id);
          params.put("password", password);
          return params;
       }
      };
    VolleySingleton.getInstance().addToRequestQueue(request);
   

The code for the CustomRequest helper is posted here
