MVC 4 - 注销控制器行为给予404未找​​到 [英] MVC 4 - LogOff controller action giving 404 not found

问题描述

我刚刚结束了一个大学的项目，我不知道如果我一直在看电脑太久，我缺少明显的东西，但是当我尝试了登录用户，我越来越404未找​​到URL /帐号/注销。

I'm just wrapping up a college project, I'm not sure if I've been staring at my computer for too long and am missing something obvious, but when I try to log a user out, I'm getting a 404 not found for the URL /Account/LogOff.

我有一个导航栏，显示登录/注销取决于用户是否，登录，或者登出：

I have a navbar that shows Log in/Log out depending on whether a user is, logged in, or, logged out:

<div class="nav-collapse collapse">
    <ul class="nav pull-right">
        <li class="dropdown" id="dropdown-login-div">
            @if (!Request.IsAuthenticated)
            {
                <a class="dropdown-toggle" href="#" data-toggle="dropdown">Sign In <strong class="caret"></strong></a>
            }
            else
            {
                @Html.ActionLink("Log Off", "LogOff", "Account")
            }
            <div class="dropdown-menu" id="dropdown-login">
                @Html.Partial("~/Views/Account/_LoginPartial.cshtml", new ViewDataDictionary<LetLord.Models.LoginModel>())
            </div>
        </li>
    </ul>
</div>

在我的帐户控制器，自带的模板互联网的默​​认注销等动作：

In my Account controller the default LogOff action that comes with the Internet template:

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult LogOff()
{
    WebSecurity.Logout();

    return View("Index");
}

有人能告诉我，为什么出现这种情况 - 之前，我把我的笔记本电脑靠在墙上。干杯。

Could someone tell me why this happening - before I throw my laptop against the wall. Cheers.

推荐答案

您使用的链接（＆LT; A /＆GT; 标签）注销导致< STRONG> HTTP GET 请求时，用户点击了它，但你的行动被限制到只服务（因为它是装饰用上传请求> [HttpPost] 属性）。

You use a link (<a/> tag) to log off which results in HTTP GET request when user clicks on it, but your action is constrained to serve POST request only (because it is decorated with [HttpPost] attribute).

您要么需要把你的链接到表单并产生POST请求，或删除 [HttpPost] 和 [ValidateAntiForgeryToken] 从你的行动（学分GalacticCowboy）。

You either need to put your link into a form and generate POST request, or remove [HttpPost] and [ValidateAntiForgeryToken] (credits to GalacticCowboy) from your action.
