java 微信授权后获取微信用户信息昵称乱码问题 解决

String getUserInfoUrl = "https://api.weixin.qq.com/sns/userinfo?access_token="+access_token+"&openid="+openid+"&lang=zh_CN";
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);
