我正在使用ASP.NET网站,我需要使用一些自定义但简单的登录机制。我从着名的Employee Info Starter Kit
开始这是我到目前为止所拥有的:
在ASP.NET页面上:
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.");
}
}
}
和实用程序类
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:管理员登录名是硬编码的名称/密码。正常的登录例程返回到另一个调用Web服务的程序集,并根据域登录检查用户名和密码。
现在,还有一个其他文件包含代码,令我感到困惑。
Global.asax中
<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>
该网站有一些允许免费访问的关于页面,但其余的是管理员或员工。我的管理员用户名/密码是固定的,但员工登录以域格式输入,需要在目标域上验证(全部完成),然后设置员工角色。
我如何在Global.asax文件的Application_AuthenticateRequest方法中执行此操作?
答案 0 :(得分:1)
为不同的文件夹设置不同的身份验证模式(通过Web.config或甚至IIS snap-in):
此外,您可以将扩展Login control与自定义Membership provider一起使用。
