當前位置：
asp.net提供了3種認證方式: windows身份驗證, Forms驗證和Passport驗證.
windows身份驗證: IIS根據應用程序的設置執行身份驗證.要使用這種驗證方式,在IIS中必須禁用匿名訪問.
Forms驗證:用Cookie來保存用戶憑證,并將未經身份驗證的用戶重定向到自定義的登錄頁.
Passport驗證:通過Microsoft的集中身份驗證服務執行的,他為成員站點提供單獨登錄和核心配置文件服務.
一. 配置windows身份驗證
1)配置IIS設置
2)設置Web.config
<system.web>
<authentication mode = "Windows">
<!--通知操作系統將當前登錄的用戶的信任書傳遞給瀏覽器-->
<authorization>
<!--禁止匿名用戶訪問-->
<deny users = "?"/>
</authorization>
</system.web>
二.配置Forms身份認證
1)配置web.config
<?xml version="1.0"?>
<!--
Note: As an alternative to hand editing this file you can use the
web admin tool to configure settings for your application. Use
the Website->Asp.Net Configuration option in Visual Studio.
A full list of settings and comments can be found in
machine.config.comments usually located in
/Windows/Microsoft.Net/Framework/v2.x/Config
-->
<configuration>
<appSettings/>
<connectionStrings/>
<!--允許匿名用戶登錄register.aspx頁-->
<location path="register.aspx">
<system.web>
<authorization>
<allow users="?" />
</authorization>
</system.web>
</location>
<system.web>
<!--
Set compilation debug="true" to insert debugging
symbols into the compiled page. Because this
affects performance, set this value to true only
during development.
-->
<compilation debug="true"/>
<!--
The <authentication> section enables configuration
of the security authentication mode used by
ASP.NET to identify an incoming user.
-->
<authentication mode="Forms">
<forms name="auth" loginUrl="login.aspx" timeout="30" protection="All" path="/"></forms>
</authentication>
<!--禁止匿名用戶登錄-->
<authorization>
<deny users="?"/>
</authorization>
<!--
The <customErrors> section enables configuration
of what to do if/when an unhandled error occurs
during the execution of a request. Specifically,
it enables developers to configure html error pages
to be displayed in place of a error stack trace.
<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>
-->
</system.web>
</configuration>
2)登錄頁面代碼
login.aspx
1<%@ Page Language="C#" AutoEventWireup="true" CodeFile="login.aspx.cs" Inherits="login" %>
2
3<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
4
5<html xmlns="http://www.w3.org/1999/xhtml" >
6<head runat="server">
7 <title>Untitled Page</title>
8</head>
9<body>
10 <form id="form1" runat="server">
11 <div>
12 <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
13 <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="登陸" /></div>
14 </form>
15</body>
16</html>
1using System;
2using System.Data;
3using System.Configuration;
4using System.Collections;
5using System.Web;
6using System.Web.Security;
7using System.Web.UI;
8using System.Web.UI.WebControls;
9using System.Web.UI.WebControls.WebParts;
10using System.Web.UI.HtmlControls;
11
12public partial class login : System.Web.UI.Page
13{
14 protected void Page_Load(object sender, EventArgs e)
15 {
16
17 }
18 protected void Button1_Click(object sender, EventArgs e)
19 {
20 FormsAuthentication.RedirectFromLoginPage(this.TextBox1.Text, false);
21 }
22}
23
三.配置Passport身份認證
需要安裝Passport Software Developer Kit.這種認證方式適合于跨站之間的應用,用戶只有一個用戶名和密碼可以訪問任何成員站。
