通知用户帐户锁定,即在ASP .NET MVC2下

Question

我必须在MVC2项目中为SqlMembershipProvider 实现" Your Account is Locked! "消息.

我怎么能这样做？

基本上我的登录代码如下:

[RequireHttps]
[HttpPost]
public ActionResult LogOn(LogOnModel model, string returnUrl)
{
      if (ModelState.IsValid)
      {
                if (MembershipService.ValidateUser(model.UserName, model.Password))
                {
                     FormsService.SignIn(model.UserName, model.RememberMe);

                     UserProfile profile = UserProfile.GetUserProfile(model.UserName);

                 //.... 
                }
                else
                {
          ModelState.AddModelError("", "The user name or password provided is incorrect.");
        }
   }

   return View(model);
}

它就像普通会员一样吗？

MembershipUser user = Membership.GetUser("Username")

if (user != null && user.IsLockedOut)
{
    return View("YourPasswordIsTooAmbiguousSoYouGotLockedOut");
}

MSDN:Membership.GetUser(字符串用户名)

- 旁注 -

您进行身份验证的顺序实际上是一个Security&UX事物.我建议使用以下伪代码(但我不是专家):

public ActionResult LogOn(LogOnModel model)
{
    // Is model valid?
    if (!ModelState.IsValid)
    {
        this.ViewData["LogOnError"] = "Bad Credentials.";
        return this.View(model);
    }

    // Is user valid?
    if(!MembershipService.ValidateUser(model.UserName, model.Password))
    {
        this.ViewData["LogOnError"] = "Wrong Credentials.";
        return this.View(model);
    }

    MembershipUser user = Membership.GetUser(model.UserName);

    // Was the user deleted in the last nano-second?
    if (user == null)
    {
        this.ViewData["LogOnError"] = "Race Condition: User previously deleted.";
        return this.View(model);
    }

    // Is user locked out?
    if(user.IsLockedOut)
    {
        this.ViewData["LogOnError"] = "You are locked out.";
        return this.View(model);
    }

    // Sign the user in.
    FormsService.SignIn(model.UserName, model.RememberMe);

    return this.View("LogOnSuccessful");
}
