asp.net的身份验证方式

来源：互联网发布：淘宝不锈钢关键词软件编辑：程序博客网时间：2024/05/25 18:10

asp.net提供了3种认证方式: windows身份验证, Forms验证和Passport验证.
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">
            
              <authorization>
                   
                  <deny users = "?"/>
            </authorization>
      </system.web>

二.配置Forms身份认证
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

-->

<system.web>

</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.

-->

<!--

The <authentication> section enables configuration

of the security authentication mode used by

ASP.NET to identify an incoming user.

-->

</authentication>

</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>

-->

</system.web>

</configuration>

2)登录页面代码 login.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="login.aspx.cs" Inherits="login" %>

<html xmlns="http://www.w3.org/1999/xhtml" >

<head runat="server">

<title>Untitled Page</title>
8

</head>

<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="登陆" /></div>
14

</form>
15

</body>

{
20

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。
