Ala*_*n T 24 asp.net-mvc mixed-mode
我有一个场景,我要求用户能够使用Windows身份验证或Forms身份验证对ASP.NET MVC Web应用程序进行身份验证.如果用户在内部网络上,他们将使用Windows身份验证,如果他们在外部连接,他们将使用Forms身份验证.我见过很多人问这个问题我如何为此配置ASP.NET MVC Web应用程序,但我还没有找到完整的解释.
有人可以通过代码示例提供有关如何完成此操作的详细说明吗？
谢谢.

这可以做到.反转配置,将app/root设置为使用匿名和表单身份验证...这样,您可以在同一个Web应用程序中配置混合身份验证,但这很棘手.首先,使用loginUrl ="〜/ WinLogin/WinLogin2.aspx"为您配置表单身份验证的应用程序.在MVC中,路由会覆盖IIS设置的身份验证规则,因此需要使用aspx页面,因为IIS可以在文件上设置身份验证.在根Web应用程序上启用匿名和表单身份验证.启用Windows身份验证并禁用root/WinLogin目录中的匿名身份验证.添加自定义401和401.2错误页面以重定向回帐户/登录URL.
这将允许任何能够传递的浏览器使用Windows集成身份验证来自动登录.虽然某些设备会被提示输入凭据(如iPhone)和其他设备,如黑莓重定向到登录页面.
这还会创建一个cookie,显式添加用户角色并创建一个通用原则,以便可以使用基于角色的授权.
在WinLogin2.aspx中(在IIS中的"根"Web应用程序下的WinLogin目录中,并配置为使用Windows身份验证,禁用匿名和启用表单(因为无法关闭...注意IIS将在您启用Windows身份验证时抱怨,直接无视(好了) :
var logonUser = Request.ServerVariables["LOGON_USER"];
if (!String.IsNullOrWhiteSpace(logonUser))
{
if (logonUser.Split('\\').Length > 1)
{
var domain = logonUser.Split('\\')[0];
var username = logonUser.Split('\\')[1];
var timeout = 30;
var encTicket = CreateTicketWithSecurityGroups(false, username, domain, timeout);
var authCookie = new HttpCookie(".MVCAUTH", encTicket) { HttpOnly = true };
Response.Cookies.Add(authCookie);
}
//else
//{
// this is a redirect due to returnUrl being WinLogin page, in which logonUser will no longer have domain attached
// ignore as forms ticket should already exist
//}
string returnUrl = Request.QueryString["ReturnUrl"];
if (returnUrl.IsEmpty())
{
Response.Redirect("~/");
}
else
{
Response.Redirect(returnUrl);
}
}
public static string CreateTicketWithSecurityGroups(bool rememberMe, string username, string domain, int timeout)
{
using (var context = new PrincipalContext(ContextType.Domain, domain))
{
using (var principal = UserPrincipal.FindByIdentity(context, IdentityType.SamAccountName, username))
{
var securityGroups = String.Join(";", principal.GetAuthorizationGroups());
var ticket =
new FormsAuthenticationTicket(1,
username,
DateTime.UtcNow,
DateTime.UtcNow.AddMinutes(timeout),
rememberMe,
securityGroups,
"/");
string encTicket = FormsAuthentication.Encrypt(ticket);
return encTicket;
}
}
}
在IIS 7.5中,单击"错误页面",将401页面设置为Redirect401.htm文件的文件路径,使用以下代码:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script>
window.location.assign('../Account/Signin');
</script>
</head>
<body>
</body>
</html>
在AccountController中......
public ActionResult SignIn()
{
return View(new SignInModel());
}
//
// POST: /Account/SignIn
[HttpPost]
public ActionResult SignIn(SignInModel model, string returnUrl)
{
if (ModelState.IsValid)
{
if (Membership.ValidateUser(model.UserName, model.Password))
{
string encTicket = CreateTicketWithSecurityGroups(model.RememberMe, model.UserName, model.Domain, FormsAuthentication.Timeout.Minutes);
Response.Cookies.Add(new HttpCookie(".MVCAUTH", encTicket));
//var returnUrl = "";
for (var i = 0; i < Request.Cookies.Count; i++)
{
HttpCookie cookie = Request.Cookies[i];
if (cookie.Name == ".MVCRETURNURL")
{
returnUrl = cookie.Value;
break;
}
}
if (returnUrl.IsEmpty())
{
return Redirect("~/");
}
return Redirect(returnUrl);
}
ModelState.AddModelError("Log In Failure", "The username/password combination is invalid");
}
return View(model);
}
//
// GET: /Account/SignOut
public ActionResult SignOut()
{
FormsAuthentication.SignOut();
if (Request.Cookies[".MVCRETURNURL"] != null)
{
var returnUrlCookie = new HttpCookie(".MVCRETURNURL") { Expires = DateTime.Now.AddDays(-1d) };
Response.Cookies.Add(returnUrlCookie);
}
// Redirect back to sign in page so user can
// sign in with different credentials
return RedirectToAction("SignIn", "Account");
}
在global.asax中:
protected void Application_BeginRequest(object sender, EventArgs e)
{
try
{
bool cookieFound = false;
HttpCookie authCookie = null;
for (int i = 0; i < Request.Cookies.Count; i++)
{
HttpCookie cookie = Request.Cookies[i];
if (cookie.Name == ".MVCAUTH")
{
cookieFound = true;
authCookie = cookie;
break;
}
}
if (cookieFound)
{
// Extract the roles from the cookie, and assign to our current principal, which is attached to the HttpContext.
FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(authCookie.Value);
HttpContext.Current.User = new GenericPrincipal(new FormsIdentity(ticket), ticket.UserData.Split(';'));
}
}
catch (Exception ex)
{
throw;
}
}
protected void Application_AuthenticateRequest()
{
var returnUrl = Request.QueryString["ReturnUrl"];
if (!Request.IsAuthenticated && !String.IsNullOrWhiteSpace(returnUrl))
{
var returnUrlCookie = new HttpCookie(".MVCRETURNURL", returnUrl) {HttpOnly = true};
Response.Cookies.Add(returnUrlCookie);
}
}
web.config中
<system.web>
