asp.net mvc 4 calling method from controller by button

问题

In my Controllers i have class AccountController and within in i have this method

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

In my Views i have cshtml page with body and this part of code

<form class="float_left" action="Controllers/AccountController" method="post">
    <button class="btn btn-inverse" title="Log out" type="submit">Log   Off</button>
</form>

And this doesn't work, anyone know what is problem or some other simple solution?

回答1:

You're not referencing the action method here:

action="Controllers/AccountController"

For starters, you don't need to specify Controllers/ because the framework will find the controller for you. Indeed, the notion of a "folder" of controllers isn't known to the client/URL/etc. What you need to give it is a "route" to the specific action method.

Since the MVC framework knows where the controllers are, you need only tell it which controller and which action method on that controller:

action="Account/LogOff"

回答2:

The action attribute is pointing to a wrong controller action. Your controller action is called LogOff and not AccountController. You should never be manually building <form> elements like that but always use the html helpers that are designed for this purpose:

@using (Html.BeginForm("LogOff", "Account"))
{
    <button class="btn btn-inverse" title="Log out" type="submit">Log Off</button>
}

回答3:

The form action should probably be /Account/LogOff

< form class="float_left" action="/Account/Logoff" method="post">
    <button class="btn btn-inverse" title="Log out" type="submit">Log Off</button>
</form>

Try putting this in the .cshtml file:

@using (Html.BeginForm("LogOff", "Account"))
{
    <button class="btn btn-inverse" title="Log out" type="submit">Log Off</button>
}
