在ASP.NET MVC 4中的SignOut（）
[英]SignOut() in asp.net MVC 4
问题描述
I have the following code to sign out and redirect to another page in the controller: 
我有以下代码可以注销并重定向到控制器中的另一个页面：
...
public ActionResult Logout(){
FormsAuthentication.SignOut();
return Redirect("Index");
}
...
I have the following "Master Page": 我有以下“母版页”：
...
<body>
<header>
<div style="background-color:deepskyblue; width:100%; height:20px">
@if(User.Identity.IsAuthenticated){
<a style="position:relative; float:right; right:15px" href="@Url.Action("Logout", "Home", null)">Logout</a>
}
else{
<a style="position: relative; float: right; right: 15px" href="@Url.Action("Login", "Home", null)">Login</a>
}
</div>
</header>
@RenderBody()
<footer>
<div style="position:relative; background-color:lightslategrey; width:100%; height:20px">
@if(User.Identity.IsAuthenticated){
<a style="position: relative; float: left; left: 15px" href="@Url.Action("Index", "Home", null)">Go back</a>
}
</div>
</footer>
</body>
...
The problem is: when the Logout action is called, it redirects to de Index page, but the header and footer do not change, I have to click "Sign out" again or Refresh the page and then it works. 问题是：调用注销操作时，它将重定向到de Index页面，但是页眉和页脚没有更改，我必须再次单击“注销”或刷新页面，然后它才能工作。
How can it work without having to click twice or refreshing the page? 它如何工作而无需单击两次或刷新页面？

Why are you using Redirect() here? 为什么在这里使用Redirect() ？ RedirectToAction() is the preferred way to issue a 302 redirect within the context of your application. RedirectToAction()是在应用程序上下文内发出302重定向的首选方法。 It adheres to your routing. 它遵循您的路由。 I would thing that Redirect("Index") would not always work as Redirect("/Controller/Index") would. 我想Redirect("Index")不会总是像Redirect("/Controller/Index")那样工作。
return RedirectToAction("Controller", "Index");

I fixed it changing this: 我修复了这一问题：
@if(User.Identity.IsAuthenticated){
<a style="position:relative; float:right; right:15px" href="@Url.Action("Logout", "Home", null)">Logout</a>
}
else{
<a style="position: relative; float: right; right: 15px" href="@Url.Action("Login", "Home", null)">Login</a>
}
with this: 有了这个：
@if(User.Identity.IsAuthenticated){
@Html.ActionLink("Logout", "Logout", "MyAccount", null, new{@style="position:relative; float:right; right:15px"})
}
else{
@Html.ActionLink("Login", "Login", "MyAccount", null, new{@style="position: relative; float: right; right: 15px"})
}
Thank you anyways for your answers. 无论如何，谢谢您的回答。
