mvc, Authorize 退回授权用户

Question

我正在尝试将 MVC 5 网页的一部分限制为特定 Active Directory 组的用户，但是 [Authorize] 属性（在控制器上）也会阻止登录用户。

我的登录页面代码如下：

public class AccountController: Controller
{

    [AllowAnonymous]
    public ActionResult Login(string returnUrl)
    {
        ViewBag.ReturnUrl = returnUrl;
        return View();
    }

    // POST: /Account/Login
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public ActionResult Login(LoginModel model, string returnUrl)
    {
        if (ModelState.IsValid)
        {
            ActiveDirectoryHelper ad = new ActiveDirectoryHelper();

            if (Membership.ValidateUser(model.UserName, model.Password))
            {
                if (ad.CheckGroupMembership(model.UserName))
                {
                    FormsAuthentication.SetAuthCookie(model.UserName, model.RememberMe);

                    if (Url.IsLocalUrl(returnUrl) && returnUrl.Length > 1 && returnUrl.StartsWith("/")
                        && !returnUrl.StartsWith("//") && !returnUrl.StartsWith("/\\"))
                    {
                        return Redirect(returnUrl);
                    }
                    else
                    {
                        return RedirectToAction("Index", "Home");
                    }
                }
                else
                {
                    ModelState.AddModelError("", "Credentials are correct but you are no authorised \n You Need membership in group: HKF-HIT-FortigateAPI-GS");
                }
            }
            else
            {
                ModelState.AddModelError("", "The user name or password provided is incorrect");
            }
        }
        // if we got this far, something failed, redisplay form
        return View(model);
    }
    // POST: /Account/LogOff
    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult LogOff()
    {
        FormsAuthentication.SignOut();
        return RedirectToAction("Index", "Home");
    }
}
public class ActiveDirectoryHelper
{
    string group = "HKF-HIT-FortigateAPI-GS";
     public bool CheckGroupMembership(string name)
    {
        var context = new PrincipalContext(
                            ContextType.Domain,
                            "AD-Domain", @"Username", "Password");

        var userPrincipal = UserPrincipal.FindByIdentity(
                            context,
                            IdentityType.SamAccountName,
                            name);

        var test = userPrincipal;

        if (userPrincipal.IsMemberOf(context,
             IdentityType.Name,
             group))
        {
            return true;
        }
        return false;
    }
}

用户通过并被重定向到 Home 控制器中的 Index。

然而，此控制器的 [Authorized] 值设置如下：

[Authorize]
public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }
}

这里的用户弹回了登录页面，就好像他没有被授权一样。

这也是 web.config：

在浏览器中我可以看到 ADAuthCookie。

编辑：问题已经解决，通过 cmets 中链接的惊人指南后，我意识到我从未在 Global.asaz.cs 类中处理过我的厨师。

向 Application_PostAuthenticateRequest 添加覆盖解决了我的问题。

我添加的代码最终使用：

protected void Application_PostAuthenticateRequest(Object sender, EventArgs e)
{
    HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName];

    if (authCookie != null)
    {
        FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);

        JavaScriptSerializer serializer = new JavaScriptSerializer();

        CustomPrincipalSerializeModel serializeModel = serializer.Deserialize<CustomPrincipalSerializeModel>(authTicket.UserData);

        CustomPrincipal newUser = new CustomPrincipal(authTicket.Name);
        newUser.Name = serializeModel.Name;
        HttpContext.Current.User = newUser;
    }
}

在 global.asax 中，我还添加了：

CustomPrincipalSerializeModel serializeModel = new CustomPrincipalSerializeModel();
serializeModel.Name = model.UserName;

JavaScriptSerializer serializer = new JavaScriptSerializer();

string userData = serializer.Serialize(serializeModel);

FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(
         1,
         model.UserName,
         DateTime.Now,
         DateTime.Now.AddMinutes(15),
         false,
         userData);

string encTicket = FormsAuthentication.Encrypt(authTicket);
HttpCookie faCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encTicket);
Response.Cookies.Add(faCookie);

到我的登录页面。

AuthorizeAttributechecks the HttpContext.User value (an IPrincipal implementation) and the HttpContext.User.Identity value (an IIdentity implementation).

Microsoft 的所有安全框架（身份、成员资格等）都使用这些接口与 MVC/ASP.NET 进行通信。如果您使用的是自定义安全框架，您还需要实现这些接口并在AcquireRequestState（如果使用会话状态）或PostAuthorizeRequest 事件中设置它们。

请参阅 ASP.NET MVC - Set custom IIdentity or IPrincipal 以了解后者以及自定义 IPrincipal 和 IIdentity 实现的示例。
