            string data_m_ninushi = JsonConvert.SerializeObject(m_ninushis);
            string sentResponse = Util.FilterData(data_m_ninushi);
            Dictionary<string, string> dataResponse = JsonConvert.DeserializeObject<Dictionary<string, string>>(sentResponse);
            if (dataResponse["ReturnValue"].Equals("0"))
            {
                return 0;

this id my code in webservice use asp.net. I use HttpWebRequest send data to symfony2 api FilterData

    XElement xdoc = XElement.Load(configFileName);
    var objStringConnection = xdoc.Descendants("URL").Select(e => new { filter_data =    e.Descendants("URL_FILTER_DATA").FirstOrDefault().Value }).SingleOrDefault();
    string urlAddress = objStringConnection.filter_data;
    System.Net.ServicePointManager.ServerCertificateValidationCallback = (senderX, certificate, chain, sslPolicyErrors) => { return true; };
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(urlAddress);
    Dictionary<string, string> json = new Dictionary<string, string>();
    json.Add("M_Ninushi", data);
    byte[] dataSent = Encoding.ASCII.GetBytes(json.ToString());
    request.Method = "POST";
    request.ContentType = "application/x-www-form-urlencoded";
    //application/x-www-form-urlencoded
    request.ContentLength = dataSent.Length;
    Stream writer = request.GetRequestStream();

    writer.Write(dataSent, 0, dataSent.Length);
    writer.Close();

    HttpWebResponse response = (HttpWebResponse)request.GetResponse();

    if (response.StatusCode == HttpStatusCode.OK)
    {
        Stream receiveStream = response.GetResponseStream();
        StreamReader readStream = null;
        if (response.CharacterSet == null)
            readStream = new StreamReader(receiveStream);
        else
            readStream = new StreamReader(receiveStream, Encoding.GetEncoding(response.CharacterSet));
        string dataResponse = readStream.ReadToEnd();
        response.Close();
        readStream.Close();
        return dataResponse;
    }

C# Code Corrections

First, we need to correct the Content-Type sent to the server hosting the Symfony2 application. The data you are sending is not in the proper format for application/x-www-form-urlencoded. Change it to application/json.

Also, JSON data MUST be encoded in Unicode. In PHP, json_decode() only supports UTF-8 encoded strings. Therefore you must use Encoding.UTF8.GetBytes instead of Encoding.ASCII.GetBytes.

Dictionary.toString() does not return a JSON string. Use Json.NET.

Receiving JSON Data in Symfony2

In your Controller, you can use Symfony\Component\HttpFoundation\Request::getContent() to retrieve the form content.

<?php
namespace Company\CodeExampleBundle\Controller;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpKernel\Exception\HttpException;

class RestAPIController extends Controller
{
    public function doSomethingInterestingAction(Request $request)
    {
        if($request->headers->get('Content-Type') !== 'application/json') {
            throw $this->createBadRequestException();
        }

        $jsonData = json_decode($request->getContent(), true);

        if($jsonData === null) {
            throw $this->createBadRequestException();
        }

        // DO SOMETHING WITH $jsonData
    }

    protected function createBadRequestException()
    {
        return new HttpException(400, 'This endpoint expects JSON data in the POST body and requires Content-Type to be set to application/json.');
    }
}
