Asp.Net核心Cookie身份验证的注销操作

我已经在Asp.Net Core 2.2中实现了身份验证,如下所示:

public async Task<IActionResult> LoginAsync(string user, string password)
    {
        if (user == "admin" && password == "admin")
        {
            var claims = new[] { new Claim(ClaimTypes.Name, user),
            new Claim(ClaimTypes.Role, "Admin") };

            var identity = new ClaimsIdentity(claims, CookieAuthenticationDefaults.AuthenticationScheme);

            await HttpContext.SignInAsync(
                CookieAuthenticationDefaults.AuthenticationScheme,
                new ClaimsPrincipal(identity));

            return RedirectToAction("Index", "Home");
        {
        else
        {
            return RedirectToAction("Login", "Users");
        }

我需要立即执行注销操作。我曾经在Asp.Net MVC中使用FormsAuthentication.SignOut()实现此目的...我需要知道在Asp.Net Core 2.2中执行此操作的正确方法

我尝试做的是这样的注销操作:

    public async void Logout()
    {
        await HttpContext.SignOutAsync();
        return RedirectToAction("Index","Home");
    }

并在我的NavBar中使用以下代码:

@if (User.Identity.IsAuthenticated)
            {
                using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" }))
                {
                    @Html.AntiForgeryToken()

                    <ul class="nav navbar-nav navbar-right">
                        <li>
                            @Html.ActionLink("Hello " + User.Identity.Name + "!", "Index", "Manage", routeValues: null, htmlAttributes: new { title = "Manage" })
                        </li>
                        <li class="nav-item">
                            <form class="form-inline" asp-area="Identity" asp-page="/Users/Logout" asp-route-returnUrl="@Url.Action("Index", "Home", new { area = "" })">
                                <button type="submit" class="nav-link btn btn-link text-dark">Logout</button>
                            </form>
                        </li>
                    </ul>
                }
            }
            else
            {
                <ul class="nav navbar-nav navbar-right">
                    <li>@Html.ActionLink("Register", "Register", "Account", routeValues: null, htmlAttributes: new { id = "registerLink" })</li>
                    <li>@Html.ActionLink("Log in", "Login", "Account", routeValues: null, htmlAttributes: new { id = "loginLink" })</li>
                </ul>
            }

遵循此documentaion

中的说明

这可以正确显示“注销”按钮,但是按该按钮似乎不会触发我的操作,并且用户也没有注销。

答案 0 :(得分:0)

原来,我只是在View中犯了一个错误。我在表单中称呼错误的动作。

  

使用(Html.BeginForm(“ 注销”,“ 帐户”,FormMethod.Post,新的{id =“ logoutForm”,@class =“ navbar-right “}))

应该已经Html.BeginForm("Logout","Users, ...)

此外,我的表单正在发送一个Post请求,因此我的动作必须用[HttpPost]装饰,如下所示:

[HttpPost]
public async Task<IActionResult> Logout()
{
    await HttpContext.SignOutAsync();
    return RedirectToAction("Index","Home");
}
