Android studio AsyncTask类将OutputStream与get请求一起使用

当我执行程序时，它返回消息：“方法不 支持请求主体：GET“，在OutputStream中，我需要发送Json Web服务的主体。 我在邮递员身上发送JSON，并得到回复

公共类信息扩展异步任务{

@Override
protected String doInBackground(String... params) {

    try {
        // Creating & connection Connection with url and required Header.
        URL url = new URL("http://");
        HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
        urlConnection.setRequestProperty("Content-Type", "application/json");
        urlConnection.setRequestMethod("GET");   //POST or GET
        urlConnection.connect();

        // Create JSONObject Request
        JSONObject jsonRequest = new JSONObject();
        jsonRequest.put("CodigoInical", "1");
        jsonRequest.put("CodigoFinal", "2");




        OutputStream outputStream = urlConnection.getOutputStream();
        DataOutputStream dataOutputStream = new DataOutputStream(outputStream);
        dataOutputStream.writeBytes(jsonRequest.toString());
        dataOutputStream.flush();
        dataOutputStream.close();

        int statusCode = urlConnection.getResponseCode();


        // Connection success. Proceed to fetch the response.
        if (statusCode == 200) {
