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>" ); %>
