如何防止 SignOutResult 导致重定向循环？

Question

我在基于 Microsoft 提供的 MusicStore 示例的 AccountController 中使用注销方法：

public class AccountController : Controller
{
    public async Task<IActionResult> Logout()
    {
        return new SignOutResult("OpenIdConnect", new AuthenticationProperties
        {
            RedirectUri = Url.Action("Index", "Home")
        });
        ////_logger.LogInformation("{userName} logged out.", userName);
    }
}

（我们正在使用 OpenID Connect 进行身份验证。）

此方法不会注销用户；相反，它会在无限循环中重定向回自身。

.NET Core 1.0.0 在使用 OpenID Connect 时注销用户的正确方法是什么？

更新:

我尝试使用下面的 SignOut 方法，但最终陷入了 302 重定向循环 /Account/SignOut?post_logout_redirect_uri=http%3A%2F%2Flocalhost%3A10565%2FAccount%2FSignedOut

我们在 Startup.cs 中的身份验证设置：

public void ConfigureServices(IServiceCollection services)
{
    services.AddAuthentication(options =>
    {
        options.SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    });

    services.AddMvc(options =>
    {
        // Globally require users to be authenticated for all controller actions
        options.Filters.Add(
            new AuthorizeFilter(
                new AuthorizationPolicyBuilder()
                    .RequireAuthenticatedUser()
                    .Build()));
    });

...

public void Configure(IApplicationBuilder app, 
                      ILoggerFactory loggerFactory, 
                      IHostingEnvironment env)
{
...
    app.UseCookieAuthentication(new CookieAuthenticationOptions());
    OpenIdConnectOptions opts = new OpenIdConnectOptions()
    {
        ClientId = Configuration["Oidc:ClientId"],
        ClientSecret = Configuration["Oidc:ClientSecret"],
        Authority = Configuration["Oidc:BaseUrl"],
        ResponseType = OpenIdConnectResponseType.Code,
        AutomaticAuthenticate = true,
        AutomaticChallenge = true
    };
    app.UseMiddleware<OktaOidcMiddleware>(Options.Create(opts));

以下是我用于 Azure Active Directory OIDC 注销的内容

    public IActionResult SignOut()
    {
        var callbackUrl = Url.Action("SignedOut", "Account", values: null, protocol: Request.Scheme);
        return SignOut(new AuthenticationProperties { RedirectUri = callbackUrl },
            CookieAuthenticationDefaults.AuthenticationScheme, OpenIdConnectDefaults.AuthenticationScheme);
    }

    public async Task EndSession()
    {
        // If AAD sends a single sign-out message to the app, end the user's session, but don't redirect to AAD for sign out.
        await HttpContext.Authentication.SignOutAsync(CookieAuthenticationDefaults.AuthenticationScheme);
    }

    public async Task<IActionResult> SignedOut()
    {
        if (HttpContext.User.Identity.IsAuthenticated)
        {
            await EndSession();
        }

        return View();
    }
