新建json.jsp文件:
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
request.setCharacterEncoding("UTF-8");//防止乱码!
String name = request.getParameter("name");
String address = request.getParameter("address");
String comment = request.getParameter("comment");
System.out.println(name + " - " +address + " - " +comment);
out.println( "{ name : '" +name+ "' , address : '"+address+ "' ,comment : '"+comment+ "' }" );
%>
新建xml.jsp文件:
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
request.setCharacterEncoding("UTF-8");//防止乱码!
String name = request.getParameter("xmlname");
String address = request.getParameter("xmladdress");
String comment = request.getParameter("xmlcomment");
System.out.println(name + " - " +address + " - " +comment);
response.setContentType("text/xml");//注意,由于你是以xml形式传递过来的,所以这里必须写。
out.print("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
out.print("<root>");
out.print("<name>"+name+"</name>");
out.print("<address>"+address+"</address>");
out.print("<comment>"+comment+"</comment>");
out.print("</root>");
%>
新建一个html.jsp文件:
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
request.setCharacterEncoding("UTF-8");//防止乱码!
String name = request.getParameter("htmlname");
String address = request.getParameter("htmladdress");
String comment = request.getParameter("htmlcomment");
System.out.println(name + " - " +address + " - " +comment);
out.println( "<div style='background-color:#ffa; padding:20px'>"+name+" "+address+" "+comment+"</div>" );
