Request.IsAuthenticated is always false
提问by Kmaczek
Can you tell me why FormsAuthentication.SetAuthCookie(user.Name, false);is not causing Request.IsAuthenticatedto be true?
你能告诉我为什么FormsAuthentication.SetAuthCookie(user.Name, false);不是Request.IsAuthenticated真的吗？
Here is my code:
这是我的代码：
[HttpPost]
public ActionResult LogIn(karcioszki.Models.UserLoginModel user)
{
if (ModelState.IsValid)
{
if (IsValid(user.Name, user.Password))
{
FormsAuthentication.SetAuthCookie(user.Name, false);
return RedirectToAction("Index", "Home");
}
else
{
ModelState.AddModelError("", "Login or password is incorrect");
}
}
return View(user);
}
and if statement:
和 if 语句：
@if (Request.IsAuthenticated)
{
<a href="@Href("~/")" class="active">Home</a>
<a href="@Href("~/Cards")">Cards</a>
@Html.ActionLink("Log out", "Logout", "User")
@Html.Encode(User.Identity.Name)
}
Also, please tell me, how to make it work?
另外，请告诉我，如何使它工作？
EDIT: I added authentication in web.config(both) but it still isn't working.
编辑：我在 web.config(both) 中添加了身份验证，但它仍然无法正常工作。

I had the same problem in an MVC5 project. The solution was to add the following lines to the modules section in the system.webServer
我在 MVC5 项目中遇到了同样的问题。解决方案是将以下几行添加到 system.webServer 中的模块部分
<remove name="FormsAuthentication" />
<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" />

You are checking if the user is authenticated. So use:
您正在检查用户是否已通过身份验证。所以使用：
if (User.Identity.IsAuthenticated)
This will fix the issue and as mentioned set the authentication element in your web.config to Forms and not Windows.
这将解决该问题，并如前所述将 web.config 中的身份验证元素设置为 Forms 而不是 Windows。
回答by Sanjay Sharma
you must set FormsAuthentication.SetAuthCookie(acct.UserName, true);after validating user and please check you must set authentication mode="Forms"in web.config.
您必须FormsAuthentication.SetAuthCookie(acct.UserName, true);在验证用户后进行设置，请检查您是否必须authentication mode="Forms"在 web.config 中设置。

I had exactly same problem in my MVC4 Web Application. One more possible reason for this problem is below method in IdentityModels.csfile
我的MVC4 Web Application. 此问题的另一个可能原因是IdentityModels.cs文件中的方法
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here
return userIdentity;
}
Make sure DefaultAuthenticationTypesis ApplicationCookie
确保DefaultAuthenticationTypes是ApplicationCookie

I was looking for about 2 hours now to solve the problem. And in case you already got setups like you are told to in several guides (as MSDN and so) and you still got the problem, the one and only thing that will solve it is to add:
我现在正在寻找大约 2 个小时来解决问题。如果您已经获得了一些指南（如 MSDN 等）中告诉您的设置，但仍然遇到问题，唯一可以解决的方法是添加：
<system.webServer>
<modules>
<remove name="FormsAuthentication" />
<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" />
</modules>
<system.webServer>
within the webconfig.
在 webconfig 中。

In my case I had this issue which ended up in a redirect-loop where the user would be redirected to the login, successfully logged in and then back to our site but since Request.IsAuthenticated was false the user was redirected to the login agan.
在我的情况下，我遇到了这个问题，它最终出现在重定向循环中，用户将被重定向到登录名，成功登录然后返回到我们的网站，但由于 Request.IsAuthenticated 为假，用户被重定向到登录名。
In our case this was solved by using another CookieManager,
在我们的例子中，这是通过使用另一个 CookieManager 解决的，
var cookieOptions = new CookieAuthenticationOptions();
cookieOptions.CookieManager = new SystemWebCookieManager();
app.UseCookieAuthentication(cookieOptions);
Turns out that there was some kind of bug in Katana that this other CookieManager worked around, in out case this solved the issue.
事实证明，Katana 中存在一些其他 CookieManager 解决的错误，以防万一这解决了问题。
