用JSP做个简单的登录注册页面
登录页面代码
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-utf-8"> <title>登录</title> <style> #a {
width:50%; height:200px; border: 1px dashed ; background-color:lightyellow; text-align:center; } body{
background-color:lightblue; } </style> </head> <body> <div id="a"> <h1>登录界面</h1> <form action="check.jsp" method="post"> 账号:<input type="text" name="id"/> <br> 密码:<input type="password"name="password"/> <br> <input type="submit" value="login"/> 没有账号？<a href ="register.jsp">注册账号</a> </form> </div> </body> </html> 注册页面代码
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>账号注册</title> </head> <style> #a {
width:50%; height:50%; border: 1px dashed ; background-color:lightgreen; text-align:center; } body{
background-color:lightyellow; } </style> <body> <%--注册框 --%> <div id="a"> <h1>注册账号</h1> <form action="registersuccess.jsp" method="post"> 账 号: <input type="text" name="id"> <br> 密 码: <input type="password"name="password"> <br> 姓名: <input type="text" name="name"> <br> 手机号: <input type="text" name="phonenumber"> <br> <input type="submit" value="注册"> <input type="submit" value="重置"> </form> </div> </body> </html> 注册成功代码
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>注册成功</title> </head> <style> #a {
width:50%; height:200px; border: 1px dashed ; background-color:lightyellow; text-align:center; } </style> <body> <div id="a"> <form action="check.jsp" method="post"> <% request.setCharacterEncoding("UTF-8"); String id=request.getParameter("id"); session.setAttribute("id", id); String name=request.getParameter("name"); session.setAttribute("name", name); String password=request.getParameter("password"); session.setAttribute("password", password); %> 恭喜您注册成功！<br> 您的账号为:<%=id %><br> 您的密码为:<%=password %><br> 请妥善保管好您的密码！<br> </form> <a href="login.jsp" style="color:#FAAF46 font-size:10px">返回登录页面</a> </div> </body> </html> 登录成功页面
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>登录成功</title> <style> body{
background-color:yellow; } #a {
width:50%; height:200px; border: 1px dashed ; background-color:lightyellow; text-align:center; } </style> </head> <body> <div id="a"> <h1 align="center"> 页面仅供测试。 </h1> <h2 align="center">登录成功</h2> </div> </body> </html> 登录失败页面
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>登录成功</title> <style> body{
background-color:grey; } #a {
width:50%; height:200px; border: 1px dashed ; background-color:lightyellow; text-align:center; } </style> </head> <body> <div id="a"> <h1 align="center"> 页面仅供测试。 </h1> <h2 align="center">登录失败</h2> <h3 align="center"><a href="login.jsp" style="color:#FAAF46 font-size:10px">返回登录页面</a></h3> </div> </body> </html> 在登录时还需要进行检验，看看账号密码是否正确
检查页面（check.jsp）主要代码（在body里面写）
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-utf-8"> <title>check</title> </head> <body> <form method="post" action=""> <% String id=(String)session.getAttribute("id"); String password=(String)session.getAttribute("password"); String name=request.getParameter("id"); session.setAttribute("name", name); String password1=request.getParameter("password"); session.setAttribute("password", password1); if(id.equals(name)&&password1.equals(password)) {
response.sendRedirect("loginsuccess.jsp");} else response.sendRedirect("loginfailure.jsp"); %> </form> </body> </html> 这个只是用session来暂存我们的数据，没有存到数据库中，所以看需求，如果有需要可以了解一下主页中这个系列的内容
