氧登陆源码
Ⅰ 有什么源码可以实现要登陆之后才能显示一个网页，请直接附上源码和教程谢谢啦~
登录后建立Session 如：Session["User"]=用户名;
判断如果存在这个Session不为空则进入页面 if(Session["User"]!=null){Response.Redirect("LuRusysterm.aspx")} 否则提示登录
或者在WebConfig里配置表单验证 在System.web下添加
<authentication mode="Forms">
<forms loginUrl="LRperson.aspx" defaultUrl="LuRusysterm.aspx" name=".ASPNETFORMSTEST" protection="All" timeout="30" ></forms>
</authentication>
<authorization>
<deny users="?"/>
</authorization>
Ⅱ JSP+javaBEAN+SERVLET登陆源码
他的意思是要,jsp里面，用了javabean，和servlet技术实现的注册登陆的源代码
Ⅲ 本地试运行源代码,想登陆后台,输入http://localhost/admin/后出现如下,怎么办
是IIS,不是ISS...
楼主是开启了目录浏览,正常的
Ⅳ JSP登陆源码
login.jsp
<%@ 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>Insert title here</title>
</head>
<body>
<form action="login" method="post">
用户名：<input type="text" name="username"/><br/>
密码：<input type="password" name="password"/><br/>
<input type="submit" value="确定"/>
</form>
</body>
</html>
success.jsp 和 error.jsp 你自己写就好一个登陆成功 一个登陆失败
三个页面都放在WebRoot下
后台
login.java
package test;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class Login extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request,response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String username = request.getParameter("username");
String password = request.getParameter("password");
if("admin".equals(username)){
request.getRequestDispatcher("/success.jsp").forward(request, response);
}else{
request.getRequestDispatcher("/error.jsp").forward(request, response);
}
}
}
web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<servlet>
<servlet-name>login</servlet-name>
<servlet-class>test.TestServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>login</servlet-name>
<url-pattern>/login</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
</web-app>
直接访问
http://127.0.0.1:8080/项目名称
用户名 admin 点击确定 登陆成功 否则 失败
Ⅳ 网页登陆源代码 （高手请进!！）
那就在IIS设置
Ⅵ asp登录界面源代码
要是你要的话。我可以发一个文件给你。里面的内容是一本书的所有例子。包括有
“留言板、注册和登陆、Blog、小型论坛、新闻发布等等。”
都是ASP版的。只要你建好站点。复制相应的文件到你站点下就行了。
Ⅶ 求一个用Java写的登陆界面的源代码，输入用户名，密码，登录后显示欢迎登录，加分
这个是我之前做着玩的，只做了个登录，不要介意，登录名：admin，密码：admin。
Ⅷ 求php实现登录成功后返回首页并在原登录处显示用户名的源代码（类似于铁血网的登录）
<?php
session_start();//用SESSION记录模式，并开启。
//用户登录信息，并记录
if(@$_POST['GoLog']){
$_SESSION['user']=@$_POST['login'];
}
//主页的检查用户登录与否，并显示欢迎信息
if(@$_SESSION['user']==''){
echo"目前没有登录";
}else{
echo$_SESSION['user']."欢迎你的回来！";
}
?>
<formaction=''method='post'>
<inputtype='text'name='login'/>
<inputtype='submit'name='GoLog'value='登录'/>
</form>
我只是给你写了个原理，你可以加入更多的判断。
Ⅸ jsp登陆界面源代码

if(name.equals("abc")&& password.equals("123")) {
3、afterLogin.jsp文件
%>
