发布请求导致连接异常导致流意外结束

Question

我正在尝试在我的应用中执行发布请求，但是我却不断收到表示“ Connection上的strean意外结束”的异常。我检查了我的请求结构几次，找不到任何错误。 如果有人可以指出我的要求出了什么问题，我将不胜感激。 预先感谢。

这是我的代码段：

            @Override
            protected JSONObject doInBackground(JSONObject... jsonObjects) {

                JSONObject serverResponse = null;
                String response = "";
                String data = jsonObjects[0].toString();
                try {

                    URL myURL = new URL(GET_INFO);
                    HttpURLConnection connection  = (HttpURLConnection)myURL.openConnection();

                    connection.setRequestMethod(REQUEST_METHOD); 
                    connection.setReadTimeout(READ_TIMEOUT);
                    connection.setConnectTimeout(CONNECTION_TIMEOUT);
                    connection.setRequestProperty("Content-Type", "application/json");

                    OutputStream outputPost = new BufferedOutputStream(connection.getOutputStream());
                    BufferedWriter writer = new BufferedWriter (new OutputStreamWriter(outputPost, "UTF-8"));
                    writer.write(data);
                    writer.flush();
                    writer.close();
                    outputPost.close();

                    if(connection.getResponseCode() == HttpURLConnection.HTTP_OK){

                        //
                    }
                    else{

                        Log.e("getDeviceInfo", "Error occurred while trying to connect to server");
                    }

                } catch (MalformedURLException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                } catch (JSONException e) {
                    e.printStackTrace();
                }


                return serverResponse;
            }
