URL url1 = new URL(getUserInfoUrl);
HttpURLConnection urlConnection = (HttpURLConnection)url1.openConnection();

// 将返回的输入流转换成字符串
InputStream inputStream = urlConnection.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream,"UTF-8");
BufferedReader in = new BufferedReader(inputStreamReader);
String jsonUserStr =in.readLine().toString();
out.println("jsonUserStr = "+jsonUserStr);

// 释放资源
inputStream.close();
inputStream = null;
urlConnection.disconnect();

JSONObject jsonUserObject = new JSONObject(jsonUserStr);
