氧登陸源碼
Ⅰ 有什麼源碼可以實現要登陸之後才能顯示一個網頁，請直接附上源碼和教程謝謝啦~
登錄後建立Session 如：Session["User"]=用戶名;
判斷如果存在這個Session不為空則進入頁面 if(Session["User"]!=null){Response.Redirect("LuRusysterm.aspx")} 否則提示登錄
或者在WebConfig里配置表單驗證 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登陸源碼
他的意思是要,jsp裡面，用了javabean，和servlet技術實現的注冊登陸的源代碼
Ⅲ 本地試運行源代碼,想登陸後台,輸入http://localhost/admin/後出現如下,怎麼辦
是IIS,不是ISS...
樓主是開啟了目錄瀏覽,正常的
Ⅳ JSP登陸源碼
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">
用戶名：<input type="text" name="username"/><br/>
密碼：<input type="password" name="password"/><br/>
<input type="submit" value="確定"/>
</form>
</body>
</html>
success.jsp 和 error.jsp 你自己寫就好一個登陸成功 一個登陸失敗
三個頁面都放在WebRoot下
後台
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>
直接訪問
http://127.0.0.1:8080/項目名稱
用戶名 admin 點擊確定 登陸成功 否則 失敗
Ⅳ 網頁登陸源代碼 （高手請進!！）
那就在IIS設置
Ⅵ asp登錄界面源代碼
要是你要的話。我可以發一個文件給你。裡面的內容是一本書的所有例子。包括有
「留言板、注冊和登陸、Blog、小型論壇、新聞發布等等。」
都是ASP版的。只要你建好站點。復制相應的文件到你站點下就行了。
Ⅶ 求一個用Java寫的登陸界面的源代碼，輸入用戶名，密碼，登錄後顯示歡迎登錄，加分
這個是我之前做著玩的，只做了個登錄，不要介意，登錄名：admin，密碼：admin。
Ⅷ 求php實現登錄成功後返回首頁並在原登錄處顯示用戶名的源代碼（類似於鐵血網的登錄）
<?php
session_start();//用SESSION記錄模式，並開啟。
//用戶登錄信息，並記錄
if(@$_POST['GoLog']){
$_SESSION['user']=@$_POST['login'];
}
//主頁的檢查用戶登錄與否，並顯示歡迎信息
if(@$_SESSION['user']==''){
echo"目前沒有登錄";
}else{
echo$_SESSION['user']."歡迎你的回來！";
}
?>
<formaction=''method='post'>
<inputtype='text'name='login'/>
<inputtype='submit'name='GoLog'value='登錄'/>
</form>
我只是給你寫了個原理，你可以加入更多的判斷。

<%
request.setCharacterEncoding("GB18030");
String name = request.getParameter("userName");
String password = request.getParameter("password");
if(name.equals("abc")&& password.equals("123")) {
3、afterLogin.jsp文件
%>
<jsp:forward page="afterLogin.jsp">
<jsp:param name="userName" value="<%=name%>"/>
</jsp:forward>
<%

</head>
<body>
<?php

$username=$_post['username'];
$password=$_post['password'];
$sql="select * from userinfo where username='$username' and password='$password'";
$re=mysql_query($sql);
$row=mysql_num_rows[$re];
if(!$row){
echo "<script>alert('用戶名或密碼錯誤!');history.back(-1);</script>";
}
else {
echo '用戶登錄成功！';
echo '<meta http-equiv=refresh content=2;url=2.php>';
}
?>
<form name="login" method="post" action="index.php">
用戶名：<input type="text" name="username" /><br/>
