asp登陸源碼
⑴ asp程序實現簡單的注冊，登錄網頁的源代碼
1，（index.asp 用戶登陸頁面）
<!-- #include file="conn.asp" -->

</table>
</form>
</center>
</body>
</html>
5，（addnewdata.asp 新用戶注冊數據處理文件）
<!-- #include file="conn.asp" -->
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>成功</title>
</head>
<body>
<%

<a href="index.asp" target="_self">注冊成功,點擊登陸</a>
</center>
<%
end if
%>
</body>
</html>
6，（conn.asp 資料庫連接文件）
<%
'連接資料庫開始
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="
'創建記錄對象
set rs=server.createobject("adodb.recordset")
%>
7，（userinfo.mdb ACCESS 資料庫）
在ACCESS中建一個表，然後在這個表中建立欄位名稱
表名：info
欄位名稱 數據類型
id 自動編號
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中的登錄注冊的源碼
分5個文件：
1：登錄頁面 login.htm
<html>
<head>
<meta http-equiv="Content-Language" content="zh-cn">
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>登錄</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>用戶名：<input name="user"></td>
</tr>
<tr>
<td>密 碼：<input type="password" name="pwd"></td>
</tr>
<tr>
<td><input name="sub" value="登錄" type="submit"></td>
</tr></form>
</table>
</body>
</html>
------------------------
2.資料庫連接文件 conn.asp
<%set rs=server.createobject("adodb.recordset")
conn = "driver={Microsoft Access Driver (*.mdb)};DBQ="&server.mappath("data.mdb")
%>
-------------------------
3:登錄檢測頁面 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'如果用戶名不存在
response.Write"<script language=javascript>alert('請輸入正確的用戶名！');history.go(-1);</script>"
Response.End()
else
if rs("pwd")<>pwd then'如果密碼不對
response.write "<script language=JavaScript>alert('密碼有誤！');history.back();</script>"
else
response.write("登錄成功")'
end if
end if%>
-------------------------------
4。注冊文件 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 ("注冊成功!")
else
rs.close
set rs=nothing
response.write ("此用戶已被注冊")
end if
%>
4。注冊頁面 re.htm
<html>
<head>
<meta http-equiv="Content-Language" content="zh-cn">
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>注冊</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>用戶名：<input name="user" size="23"></td>
</tr>
<tr>
<td>密 碼：<input name="pwd" size="23" id="pwd"></td>
</tr>
<tr>
<td><input name="sub" value="注冊" type="submit"></td>
</tr></form>
</table>
</body>
</html>
將這幾個文件和資料庫「data.mdb」放在同一目錄內
資料庫建一個USER表
含name pwd 兩個欄位 文本類型
運行login.htm測試登錄
運行re.htm測試注冊
⑶ 用戶登錄 asp+sql源碼
資料庫建立一個表admin 3個列：Username Passwd oskey（用戶級別）
ODBC數據源創建一個sql的數據源與你建立的資料庫連上。
conn.asp
<%
set conn=server.createobject("adodb.connection")
conn.connectionstring="DSN=ccsw;uid=sa;pwd=1234"
conn.open
%>

檢查用戶界面：
<!--#include file=articleconn.asp-->
<%
dim rs
UserName1=request.form("UserName")'獲得登錄界面輸入的用戶名
Passwd1=request.form("PassWd")''獲得登錄界面輸入的密碼
set rs=server.CreateObject("ADODB.RecordSet")'建立資料庫連接
rs.open "select * from admin where UserName='" & UserName1 & "' and passwd='"&passwd1&"'",conn,1 '查詢該用戶名和密碼是否存在
if rs.eof or rs.bof then '當沒有符合篩選結果時，則執行下面的句子
response.write "<script language=javascript>"
response.write "alert('用戶或密碼不對!');"
response.write "javascript:history.go(-1);"
response.write "</script>" '用javascript腳本提示用戶
else '如果符合條件的時候
session("UserName")=RS("Username") '新建session，值等於表單傳來的用戶名
session("KEY")=rs("OSKEY")
response.write"<SCRIPT language=JavaScript>alert('登錄成功');"
response.write"this.location.href='admin.asp';</SCRIPT>"
end if '結束if語句
%>
