JSP使http獲取請求並獲得json響應

Question

我想做一個獲取json響應的http get請求。在該會話響應中，我想將值存儲到我的會話中。這是如何實現的？

謝謝

這裏是示例代碼。你會在recvbuff中有迴應。

<%@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); 
%>
