JSP使http获取请求并获得json响应 [英] JSP make http get request and get json response

问题描述

我想创建一个获取json响应的http get请求。在该会话响应中，我想将值存储到我的会话中。这怎么可以实现？

I would like to make a http get request which gets a json response. In that session response I would like to store a value into my session. How is this achievable?

谢谢

推荐答案

以下是示例代码。你将在recvbuff中得到回复。

Here is the sample code. You'll have response in recvbuff.

<%@page import="java.io.*" %>
<%@page import="java.net.*" %>

<%
   String recv;
   String recvbuff;
   URL jsonpage = new URL("http://www.yoursite.com/jsonresponse");
   URLConnection urlcon = jsonpage.openConnection();
   BufferedReader buffread = new BufferedReader(new InputStreamReader(urlcon.getInputStream()));

   while ((recv = buffread.readLine()) != null)
    recvbuff += recv;
   buffread.close();

   System.out.println(recvbuff);
%>
