2 HttpURLConnection httpURLConnection = (HttpURLConnection) realurl.openConnection();
3 httpURLConnection.setRequestMethod("POST");
4 httpURLConnection.setRequestProperty("Content-type","application/json");
5 httpURLConnection.setDoInput(true);
6 httpURLConnection.setDoOutput(true);
7 DataOutputStream out = new DataOutputStream(httpURLConnection.getOutputStream());
8 out.write(info.toString().getBytes("UTF-8")); //info为JSONObject类型，为请求参数，格式为{"entity":{"id":"123456","name":"levi"}}
9 out.flush();
10 out.close();
11 InputStream inputStream = httpURLConnection.getInputStream();
12 String byteArrayOutputStream = streamToString(inputStream); //streamToString为一个转化方法，将inputStream 类型转为String类型
13 JSONObject result = JSONObject.parseObject(byteArrayOutputStream);
