我工作的一个ASP.NET网站，我需要离开一些自定义，但简单的登录机制。我是从著名的员工信息入门套件

I'm working on a ASP.NET website and I need to get away with some custom but simple login mechanism. I started from the famous Employee Info Starter Kit

这是我到目前为止有：

在一个ASP.NET页面：

protected void ButtonLogOn_Click(object sender, EventArgs e)
{
    if (String.IsNullOrEmpty(txtUserName.Value) || String.IsNullOrEmpty(txtPassword.Value))
        labelMessage.Text = MessageFormatter.GetFormattedErrorMessage("You can login using a username and a password associated with your account. Make sure that it is typed correctly.");
    else
    {
        //if the log-in is successful
        LoginPage LoginBack = new LoginPage();

        if (LoginBack.VerifyCredentials(txtUserName.Value, txtPassword.Value) == 0)
        {
            SiteLogin.PerformAuthentication(txtUserName.Value, checkBoxRemember.Checked);
        }
        else
        {
            labelMessage.Text = MessageFormatter.GetFormattedErrorMessage("<strong>Login Failed!</strong><hr/>The username and/or password you entered do not belong to any User account on our system.<br/>You can login using a username and a password associated with your account. Make sure that it is typed correctly.");
        }
    }
}

protected void ButtonAdminLogOn_Click(object sender, EventArgs e)
{
    if (String.IsNullOrEmpty(txtUserName.Value) || String.IsNullOrEmpty(txtPassword.Value))
        labelMessage.Text = MessageFormatter.GetFormattedErrorMessage("<strong>Login Please!</strong><hr/>You can login using a username and a password associated with your account. Make sure that it is typed correctly.");
    else
    {
        //if the log-in is successful
        if (txtUserName.Value == "admin" && txtPassword.Value == "123123")
        {
            SiteLogin.PerformAdminAuthentication("admin", checkBoxRemember.Checked);
        }
        else
        {
            labelMessage.Text = MessageFormatter.GetFormattedErrorMessage("<strong>Login Failed!</strong><hr/>The username and/or password you entered do not belong to any Administrator ccount on our system.<br/>You can login using a username and a password associated with your account. Make sure that it is typed correctly.");
        }
    }
}

和一项实用类

public static void PerformAuthentication(string userName, bool remember)
{
    FormsAuthentication.RedirectFromLoginPage(userName, remember);

    if (HttpContext.Current.Request.QueryString["ReturnUrl"] == null)
    {
        RedirectToDefaultPage();
    }
    else
    {
        HttpContext.Current.Response.Redirect(HttpContext.Current.Request.QueryString["ReturnUrl"]);
    }
}

public static void PerformAdminAuthentication(string userName, bool remember)
{
    FormsAuthentication.RedirectFromLoginPage(userName, remember);

    if (HttpContext.Current.Request.QueryString["ReturnUrl"] == null)
    {
        RedirectToAdminDefaultPage();
    }
    else
    {
        HttpContext.Current.Response.Redirect(HttpContext.Current.Request.QueryString["ReturnUrl"]);
    }
}

我的登录表单，有两个按钮：管理员登录是硬codeD名/密码。正常登录程序返回到调用Web服务并获得用户名和密码核对域登录另一个程序。

My login form has two buttons: The Admin login is hard-coded name/password. The normal login routine goes back to another assembly that calls a web service and get the username and password checked against a domain login.

现在，也有code和莫名其妙我。另一个文件

Now, there is one other file that has code and is baffling me.

的Global.asax

<script RunAt="server">
protected void Application_AuthenticateRequest(Object sender, EventArgs e)
{
    if (HttpContext.Current.User != null)
    {
        if (HttpContext.Current.User.Identity.IsAuthenticated)
        {
            if (HttpContext.Current.User.Identity.AuthenticationType != "Forms")
            {
                throw new InvalidOperationException("Only forms authentication is supported, not " +
                        HttpContext.Current.User.Identity.AuthenticationType);
            }

            IIdentity userId = HttpContext.Current.User.Identity;

            //if role info is already NOT loaded into cache, put the role info in cache
            if (HttpContext.Current.Cache[userId.Name] == null)
            {
                string[] roles;

                if (userId.Name == "admin")
                {
                    roles = new string[1] { "administrators" };
                }
                else if (userId.Name == "member1")
                {
                    roles = new string[1] { "employees" };
                }
                else
                {
                    roles = new string[1] { "public" };
                }

                //1 hour sliding expiring time. Adding the roles in cache. 
                //This will be used in Application_AuthenticateRequest event located in Global.ascx.cs 
                //file to attach user Principal object.
                HttpContext.Current.Cache.Add(userId.Name, roles, null, DateTime.MaxValue, TimeSpan.FromHours(1), CacheItemPriority.BelowNormal, null);
            }

            //now assign the user role in the current security context
            HttpContext.Current.User = new GenericPrincipal(userId, (string[])HttpContext.Current.Cache[userId.Name]);
        }
    }

}
</script>

该网站有一些关于页面，允许自由进入，但其余的要么是管理员或员工。我的管理员用户名/密码是固定的，但雇员登录输入域格式，需要在目标域进行验证（所有正在做的），然后设置员工的作用。

The website has a few About pages that allow free access but the rest is either for admin or employee. My admin username/password is fixed but the employee login is entered in domain format and needs to be verified on target domain (all being done) and then set the employee role.

我该怎样做，在Application_AuthenticateRequest方法在Global.asax文件？

How am I to do that in the Application_AuthenticateRequest method in Global.asax file?

推荐答案

设置不同的身份验证模式不同的文件夹（通过的的Web.config 甚至只是的 IIS管理单元）：

Set different auth modes for different folders (via Web.config or even just IIS snap-in):

你也可以使用扩展登录控制自定义会员提供。

Also you can use extended Login control with custom Membership provider.
