============问题描述============
小弟在做一个客户端的购物车功能，要获取到服务器session中保存的购物车列表，上传了sessionid却依旧没法获取到购物车，代码在下面：
String urlString = "http://192.168.1.128:8080/Pinzhuo04/servlet/ShowCartServlet";
HttpURLConnection httpURLConnection = (HttpURLConnection) new URL(
urlString).openConnection();
httpURLConnection.setRequestProperty("cookie", sessionid);
httpURLConnection.setConnectTimeout(5000);
httpURLConnection.setRequestMethod("POST");
if (httpURLConnection.getResponseCode() != -1) {
InputStream inputStream = httpURLConnection.getInputStream();
return XMLparse(inputStream);
}
