    Dictionary<string, string> data = JsonConvert.DeserializeObject<Dictionary<string, string>>(json);
        if (data["ReturnValue"].Equals("0"))
        {
            List<M_Ninushi> m_ninushis = new M_NINUSHI_DAO().GetList(data["LastUpdateDate"]);
            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);

c#代码更正

首先，我们需要更正发送到承载Symfony2应用程序的服务器的Content-Type。您发送的数据不是application/x-www-form-urlencoded的正确格式。修改为application/json

同样，JSON数据必须用Unicode编码。在PHP中，json_decode()只支持UTF-8编码的字符串。因此，您必须使用Encoding.UTF8.GetBytes而不是Encoding.ASCII.GetBytes。

Dictionary.toString()不返回JSON字符串。使用Json.NET .

在Symfony2中接收JSON数据

在Controller中，您可以使用Symfony'Component'HttpFoundation'Request::getContent()来检索表单内容。

<?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.');
    }
}
