angular - 从 Identity Server 4 注销不会从客户端注销

Question

我有类似的问题 https://github.com/IdentityServer/IdentityServer4/issues/3153

我正在使用 Asp Net Identity 和 EF Core 组合示例，一切正常，数据库、播种、api 调用，除了我尝试从 IS 页面注销时。它不会删除 .AspNetCore.Cookies这是保持用户登录客户端的方式。

    [HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> Logout(LogoutInputModel model)
    {

        // build a model so the logged out page knows what to display
        var vm = await BuildLoggedOutViewModelAsync(model.LogoutId);

        if (User?.Identity.IsAuthenticated == true)
        {
            _log.LogCustomInfo(LoggingType.Information, "<AUDIT>" + "Logout: User Is Authenticated" + "</AUDIT>");

            try
            {
                await _signInManager.SignOutAsync();
                await HttpContext.SignOutAsync(IdentityConstants.ApplicationScheme);
                await HttpContext.SignOutAsync(IdentityConstants.ExternalScheme);
                // raise the logout event
                await _events.RaiseAsync(new UserLogoutSuccessEvent(User.GetSubjectId(), User.GetDisplayName()));
            }
            catch (NotSupportedException)
            {
                _log.LogCustomInfo(LoggingType.Information, "<AUDIT>" + "Logout: SignOutAsync Not Supported" + "</AUDIT>");
            }

        }

        /* https://github.com/IdentityServer/IdentityServer4/issues/855 */
        // check if we need to trigger sign-out at an upstream identity provider

        // delete local authentication cookie
        Response.Cookies.Delete(".AspNetCore.Identity.Application");
        Response.Cookies.Delete("idserv.external");
        Response.Cookies.Delete("idserv.session");


        _log.LogCustomInfo(LoggingType.Information, "<AUDIT>" + "Logout: Trigger external signout " + vm.TriggerExternalSignout +  "</AUDIT>");

        if (vm.TriggerExternalSignout)
        {

            // build a return URL so the upstream provider will redirect back
            // to us after the user has logged out. this allows us to then
            // complete our single sign-out processing.
            string url = Url.Action("Logout", new { logoutId = vm.LogoutId });
            //url = _configuration["AppSettings:PostLogoutRedirectUri"]; 
            url = vm.PostLogoutRedirectUri;
            //url = "redirect.html";
                                            // this triggers a redirect to the external provider for sign-out
            _log.LogCustomInfo(LoggingType.Information, "<AUDIT>" + "Logout: Redirect to " + url +  "</AUDIT>");

            return SignOut(new AuthenticationProperties { RedirectUri = url }, vm.ExternalAuthenticationScheme);
        }

        return View("LoggedOut", vm);
    }

我在 angular 客户端和 MVC 应用程序中遇到了同样的问题。

如果我手动删除 .AspNetCore.Identity.Application客户端已注销。我正在使用 keycloak 进行身份验证并使用

    options.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme;
    options.SignOutScheme = IdentityServerConstants.SignoutScheme;

在启动IS配置选项中。

我知道这是一个老问题，但我遇到了同样的问题。
事实证明，我从 repo 中获得的代码没有删除问题所做的 cookie 的行。一旦我添加它，注销实际上已注销。

Response.Cookies.Delete(".AspNetCore.Identity.Application");
Response.Cookies.Delete("idserv.external");
Response.Cookies.Delete("idserv.session");

该 repo 适用于当前最新的 IdentityServer4 4.1.1 并且应该可以正常工作，因为它是演练的结果。
