一、写前台jsp页面index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>My JSP 'index.jsp' starting page
二、写后台Servlet加random随机数,关键代码如下:
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("utf-8"); //用utf-8转换获得传输过来的码
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String txt = request.getParameter("txt");
// String tx = new String(txt.getBytes("iso-8859"),"utf-8");
out.print("txt="+txt+Math.random());
out.flush();
out.close();
}
/**
* The doPost method of the servlet.
*
* This method is called when a form has its tag value method equals to post.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
String username = request.getParameter("username");
// String txt = new String(username.getBytes("ISO-8859-1"),"UTF-8");
String txt = new String(username);
out.print("txt="+txt+":"+Math.random());
out.flush();
out.close();
