将json作为对象从android发送到wcf

我有一个“wcf”rest服务，它接收一个自定义类作为输入参数。我想通过android平台发送这个类对象数据。我使用了

httpUrlConnection

。我总是收到回复代码500。但该服务在windows窗体应用程序中正常工作。我的android代码如下：

        HttpURLConnection urlConnection = null;
        String jsonString = "";
        JSONObject jsonObject = new JSONObject();
        JSONObject jsonObject2 = new JSONObject();
        try {

            jsonObject.put("A","rtrt");
            jsonObject2.put("c",jsonObject);
               } catch (JSONException e) {
                 e.printStackTrace();
               }


        try{
            URL url = new URL("http://.../Service1.svc/GetTestData");
            urlConnection = (HttpURLConnection) url.openConnection();
            urlConnection.setDoOutput(true);
            urlConnection.setDoInput(true);
            urlConnection.setRequestMethod("POST");
              urlConnection.setRequestProperty("ContentType","applicaiton/json");


          urlConnection.setUseCaches(false);

      urlConnection.connect();

            OutputStream outputStream = new BufferedOutputStream(urlConnection.getOutputStream());
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(outputStream, "utf-8"));
            writer.write(jsonObject2.toString());
            writer.flush();
            writer.close();
            outputStream.close();

       int statusCode = urlConnection.getResponseCode();

           // Log.d("TRAFFIC", "err: " + urlConnection.getErrorStream().toString());

在HttpUrlConnection中，不应在读取inputstream之前关闭outputstream。所以我删除了所有outputstream关闭

这是不正确的。如果您更改绑定并将其设置为webhttpbinding，Wcf支持rest。我是.Net和Android开发者，很久以前就遇到过这个问题，Ksoap2是解决方案。这是不正确的。如果您更改绑定并将其设置为webhttpbinding，Wcf支持rest。我是.Net和Android开发者，早在几天前就面临这个问题，Ksoap2就是解决方案。

    SoapPrimitive result = (SoapPrimitive)envelope.getResponse();

    //to get the data
    String resultData = result.toString();
    // 0 is the first object of data 


    sb.append(resultData + "\n");
    } catch (Exception e) {
    sb.append("Error:\n" + e.getMessage() + "\n");
    }

}
