登录方式：

[HttpPost]
public ActionResult LogIn(UserModel user)
{
     if (ModelState.IsValid)
     {
         if (IsValid(user.Email, user.Password))
         {
             System.Web.Security.FormsAuthentication.SetAuthCookie(user.Email, false);
             return RedirectToAction("Index", "Home");
         }
         else
         {
              ModelState.AddModelError("", "Login data is incorrect.");
         }
     }
     return View(user);
}

和代码：

@if (Request.IsAuthenticated)
{
     <strong>@Html.Encode(User.Identity.Name)</strong>
     @Html.ActionLink("Log Out", "Logout", "User")
 }
 else
 {
     @Html.ActionLink("Register", "Register", "User")
     <span> | </span>
     @Html.ActionLink("Log in", "Login", "User")
 }

@Edit 的登录：

@using (Html.BeginForm())
{
    @Html.ValidationSummary(true, "Login failed. Check your login details")
    <div>
        <fieldset>
            <legend>Login form</legend>
            <div>@Html.LabelFor(u => u.Email)</div>
            <div>
            @Html.TextBoxFor(u=>u.Email)
            @Html.ValidationMessageFor(u=>u.Email)
            </div>

            <div>@Html.LabelFor(u => u.Password)</div>
            <div>
                @Html.PasswordFor(u => u.Password)
                @Html.ValidationMessageFor(u => u.Password)
            </div>

            <input type="submit" value="Log In"/>

        </fieldset>
    </div>
}

然后我点击按钮logIn（这个代码中没有显示）然后我去： public ActionResult LogIn(UserModel user)方法。然后我有vaild等...
下一步：System.Web.Security.FormsAuthentication.SetAuthCookie(user.Email, false); 但是当页面刷新时，我看不到我的user.Email，但是所有时间都看到Register | Log In，但必须是f as2@email.com | Log Out。它类似于：Request.IsAuthenticated == false

我该如何解决？

Answer 1

替换

<authentication mode="None" />

与

<authentication mode="Forms">
  <forms loginUrl="~/Account/Login" timeout="60" />
</authentication>

（调整timeout属性的值以满足您的需求）

Answer 2

您似乎删除了web.config中的FormsAuthenticationModule：

<system.webServer>
    <modules>
      <remove name="FormsAuthenticationModule" />
    </modules>
</system.webServer>

我对MVC中的所有内容都不熟悉，但是如果你没有其他任何东西可以处理身份验证我就不会删除FormsAuthenticationModule

ASP.NET MVC 4中的FormsAuthentication不起作用
