windows身份验证: IIS根据应用程序的设置执行身份验证.要使用这种验证方式,在IIS中必须禁用匿名访问.
Forms验证:用Cookie来保存用户凭证,并将 未经身份验证的用户重定向到自定义的登录页.
Passport验证:通过Microsoft的集中身份验证服务执行的,他为成员站点提供单独登录 和核心配置文件服务.
一. 配置windows身份验证
1)配置IIS设置
2)设置Web.config
<system.web>
<authentication mode = "Windows">
<!--通知操作系统将当前登录的用户的信任书传递给浏览器-->
<authorization>
<!--禁止匿名用户访问-->
<deny users = "?"/>
</authorization>
</system.web>
二.配置Forms身份认证
1)配置web.config
复制代码 代码如下:
<?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/>
<!--允许匿名用户登录register.aspx页-->
<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 loginUrl="login.aspx" timeout="30" protection="All" path="https://www.jb51.net/"></forms>
</authentication>
<!--禁止匿名用户登录-->
<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)登录页面代码
login.aspx
[/code]
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="login.aspx.cs" Inherits="login" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form runat="server">
<div>
<asp:TextBox runat="server"></asp:TextBox>
<asp:Button runat="server" Text="登陆" /></div>
</form>
</body>
</html>
复制代码 代码如下:
[code]
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class login : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
FormsAuthentication.RedirectFromLoginPage(this.TextBox1.Text, false);
}
}
三.配置Passport身份认证
需要安装Passport Software Developer Kit.这种认证方式适合于跨站之间的应用,用户只有一个用户名和密码可以访问任何成员站。
IIS 身份验证
如果 ASP.NET 针对 Windows 身份验证进行配置，则 ASP.NET 依靠 IIS，利用配置好的身份验证模式对其客户端进行身份验证。IIS 通过检查特定应用程序的元数据库设置来确定其身份验证模式。成功验证某个用户的身份后，IIS 将代表经过身份验证的用户的 Windows 令牌传递给宿主 ASP.NET 的 ASP.NET 辅助进程 (w3wp.exe)。如果应用程序使用在 IIS 中配置的虚拟目录来支持匿名访问，该令牌代表匿名 Internet 用户帐户；否则，该令牌代表经过身份验证的用户。
IIS 支持以下身份验证模式：
