asp登陆源码
⑴ asp程序实现简单的注册，登录网页的源代码
1，（index.asp 用户登陆页面）
<!-- #include file="conn.asp" -->
<!-- blog.soowooo.cn 悠悠长假期 -->

<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>会员</title>
<style type="text/css">
<!--
body,td,th {
font-family: 宋体;
font-size: 14px;
}
-->
</style>
</head>
<body>

2，（login.asp 用户数据处理文件）

</body>
</html>
6，（conn.asp 数据库连接文件）
<%
'连接数据库开始
dim conn,rs,sql
on error resume next
dbpath=server.mappath("userinfo.mdb")
set conn=server.createobject("adodb.connection")
conn.open "PROVIDER=Microsoft.jet.OLEDB.4.0;data source="
'创建记录对象
set rs=server.createobject("adodb.recordset")
%>
7，（userinfo.mdb ACCESS 数据库）
在ACCESS中建一个表，然后在这个表中建立字段名称
表名：info
字段名称 数据类型
id 自动编号
username 文本
password 文本
sex 文本
quest 文本
qq 文本
mail 文本
personalinfo 文本
ntime 文本
⑵ 求asp中的登录注册的源码
分5个文件：
1：登录页面 login.htm
<html>
<head>
<meta http-equiv="Content-Language" content="zh-cn">
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>登录</title>
</head>
<body>
<table border="0" cellpadding="0" cellspacing="0" width="33%" height="64" id="table1">
<form name="form" action="go.asp" method="post"><tr>
<td>用户名：<input name="user"></td>
</tr>
<tr>
<td>密 码：<input type="password" name="pwd"></td>
</tr>
<tr>
<td><input name="sub" value="登录" type="submit"></td>
</tr></form>
</table>
</body>
</html>
------------------------
2.数据库连接文件 conn.asp
<%set rs=server.createobject("adodb.recordset")
conn = "driver={Microsoft Access Driver (*.mdb)};DBQ="&server.mappath("data.mdb")
%>
-------------------------
3:登录检测页面 go.asp
<!-- #include file="conn.asp" -->
<%
pwd=request.Form("pwd")
set rs=server.createobject("adodb.recordset")
sql="select * from user where name='"&request.Form("user")&"'"
rs.open sql,conn,1,1
if rs.eof or rs.bof then'如果用户名不存在
response.Write"<script language=javascript>alert('请输入正确的用户名！');history.go(-1);</script>"
Response.End()
else
if rs("pwd")<>pwd then'如果密码不对
response.write "<script language=JavaScript>alert('密码有误！');history.back();</script>"
else
response.write("登录成功")'
end if
end if%>
-------------------------------
4。注册文件 add.asp
<!-- #include file="conn.asp" -->
<%
sql="select * from user where u_user='"&request.Form("user")&"'"
set rs=server.createobject("adodb.recordset")
rs.open sql,conn,1,3
if rs.BOF or rs.EOF then
rs.addnew
rs("name")=request.Form("user")
rs("pwd")=request.Form("pwd")
rs.update
rs.close
set rs=nothing
response.Write ("注册成功!")
else
rs.close
set rs=nothing
response.write ("此用户已被注册")
end if
%>
4。注册页面 re.htm
<html>
<head>
<meta http-equiv="Content-Language" content="zh-cn">
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>注册</title>
</head>
<body>
<table border="0" cellpadding="0" cellspacing="0" width="33%" height="64" id="table1">
<form name="form" action="add.asp" method="post"><tr>
<td>用户名：<input name="user" size="23"></td>
</tr>
<tr>
<td>密 码：<input name="pwd" size="23" id="pwd"></td>
</tr>
<tr>
<td><input name="sub" value="注册" type="submit"></td>
</tr></form>
</table>
</body>
</html>
将这几个文件和数据库“data.mdb”放在同一目录内
数据库建一个USER表
含name pwd 两个字段 文本类型
运行login.htm测试登录
运行re.htm测试注册
⑶ 用户登录 asp+sql源码
数据库建立一个表admin 3个列：Username Passwd oskey（用户级别）
ODBC数据源创建一个sql的数据源与你建立的数据库连上。
conn.asp
<%
set conn=server.createobject("adodb.connection")
conn.connectionstring="DSN=ccsw;uid=sa;pwd=1234"
conn.open
%>
index.asp

检查用户界面：
<!--#include file=articleconn.asp-->
<%
dim rs
UserName1=request.form("UserName")'获得登录界面输入的用户名
Passwd1=request.form("PassWd")''获得登录界面输入的密码
set rs=server.CreateObject("ADODB.RecordSet")'建立数据库连接
rs.open "select * from admin where UserName='" & UserName1 & "' and passwd='"&passwd1&"'",conn,1 '查询该用户名和密码是否存在
if rs.eof or rs.bof then '当没有符合筛选结果时，则执行下面的句子
response.write "<script language=javascript>"
response.write "alert('用户或密码不对!');"
response.write "javascript:history.go(-1);"
response.write "</script>" '用javascript脚本提示用户
else '如果符合条件的时候
session("UserName")=RS("Username") '新建session，值等于表单传来的用户名
session("KEY")=rs("OSKEY")
response.write"<SCRIPT language=JavaScript>alert('登录成功');"
response.write"this.location.href='admin.asp';</SCRIPT>"
end if '结束if语句
%>
