Question

我正在尝试将MVC 5网页的某个部分限制为某个Active目录组的用户，但[Authorize]属性（在控制器上）会阻止用户登录。

我的登录页面代码如下所示：

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;
    }
}

用户通过并重定向到Home Controller中的Index。

然而，该控制器的[授权]值设置如下：

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

此处用户反弹回登录页面，好像他没有被授权。

这也是web.config：

编辑：问题已经解决，在通过评论中链接的惊人指南后，我意识到我从未在Global.asaz.cs类中处理我的库克。

为Application_PostAuthenticateRequest添加一个Overover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。

Answer 1

AuthorizeAttribute checks 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，则还需要实现这些接口并在AcquireRequestState（如果使用会话状态）或PostAuthorizeRequest事件中进行设置。

有关后者的示例以及自定义IPrincipal和IIdentity实施，请参阅ASP.NET MVC - Set custom IIdentity or IPrincipal。
