找不到资源asp.net MVC

Question

I am familiarizing myself with asp.net mvc, Identity and trying a simple log off but get The resource cannot be found.

in my html page

<li><a href="@Url.Action("LogOff", "Account")" id="home">Log off</a></li>

and this is in the AccountController

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult LogOff()
    {
        AuthenticationManager.SignOut();
        return RedirectToAction("Index", "Home");
    }

and this in my route config file

 routes.MapRoute(
         null,
         "LogOff",
         new { controller = "Account", action = "LogOff" }

What could I be missing?

Answer 1

Remove [HttpPost] from LogOff method

[ValidateAntiForgeryToken]
public ActionResult LogOff()
{
    AuthenticationManager.SignOut();
    return RedirectToAction("Index", "Home");
}

Answer 2

simply putting by removing HttpPost

public ActionResult LogOff()
{
    AuthenticationManager.SignOut();
    return RedirectToAction("Index", "Home");
}

works for me

Answer 3

Use the post method to log off. See the below example.

   @using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new { id = "logoutForm" })) {
            @Html.AntiForgeryToken()
            <a href="javascript:document.getElementById('logoutForm').submit()">Log off</a>
        }

Answer 4

By default when you creating project with some Authentication it creates LogOff method with HttpPost attribute.

So You have two ways to fix it

first one is to remove this attribute. And let your Code looks like

[ValidateAntiForgeryToken]
public ActionResult LogOff()
{
    AuthenticationManager.SignOut();
    return RedirectToAction("Index", "Home");
}

second one is to change your html to use @Html.BeginForm with POST method docs here .

By default projects used second type of realization

EDIT While I was typing this answer Rad give an sample how to use BeginForm helper here it is
