jsp内置对象—response对象学习笔记

Response对象用于动态响应客户端请示，控制发送给用户的信息，并将动态生成响应。
今天上机课做response将网页保存为word、excel和ppt。很奇怪下载的文件格式为.jsp。贴代码：

<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">

    <title>My JSP 'index.jsp' starting page</title>
    <meta http-equiv="pragma" content="no-cache">
    <meta http-equiv="cache-control" content="no-cache">
    <meta http-equiv="expires" content="0">    
    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    <meta http-equiv="description" content="This is my page">
    <!--
    <link rel="stylesheet" type="text/css" href="styles.css">
    -->
  </head>

  <body>
  <p>将本网页分别保存为word、excel和ppt。</p>
  <p>将为网页存储为?</p>
  <form action="" mothed="get" name=form>
  <input type="submit" value="word" name="submit">
  <input type="submit" value="excel" name="submit">
  <input type="submit" value="ppt" name="submit">
  </form>
  <% String str=request.getParameter("submit");
  if(str==null){
  str="";
  }
  if(str.equals("word")){
  response.setContentType("application/msword;charset=gb2312");
  }
  if(str.equals("excel")){
  response.setContentType("application/ms-excel;charset=gb2312");
  }
  if(str.equals("ppt")){
  response.setContentType("application/ms-powerpoint;charset=gb2312");
  }
  %>
  </body>
</html>
