This article provides an example of how JSP implements a simple user login and displays user information.Share it for your reference.The implementation is as follows:

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>  

<%  

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>  

  </head>  

    

  <body>  

  <form action="login_success.jsp" method = "post">  

    User name: <input type ="text" name = "username"/><br>  

    Password: <input type = "password" name ="password"><br>  

   <input type ="submit" value=" Submit "/>   

   </form>  

  </body>  

</html>

login_success.jsp is used to display user information

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>  

<%  

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>  

  </head>  

    

  <body>  

  <%  

  String uname = request.getParameter("username");  

  String pwd = request.getParameter("password");  

  out.println(uname);  

  out.println(pwd);  

   %>  

  </body>  

</html>

I hope that the description in this paper will be helpful to everyone's jsp program design.
