HttpContext.Current.GetOwinContext().Authentication.Challenge() 不打开 adfs 页面

Question

我有一个与 Angular js 一起使用的单页 mvc 应用程序。 Angular 从我的 asp mvc 应用程序（包括登录名）调用 api。我想在我的应用程序中添加单点登录

在转移到本地登录页面之前我的角度检查“GetUserRoles”功能..

我做错了什么，所以 UserAccountApiController 中的 HttpContext.Current.GetOwinContext().Authentication.Challenge() 行没有打开 adfs sso 页面???

UserAccountApiController

    [HttpPost]
    public bool IsLogedInRoled(NR role)
    {
        if (User.Identity.IsAuthenticated)
        {
            if (!string.IsNullOrEmpty(role.role))
            {
                var isLogedInRoled = GetUserRoles().Select(x => x.ToLower()).Contains(role.role);
                return isLogedInRoled;
            }
            return true;
        }
        HttpContext.Current.GetOwinContext().Authentication.Challenge(new AuthenticationProperties { RedirectUri = "~/" },
            WsFederationAuthenticationDefaults.AuthenticationType);

        return false;

    }

请从您的 UserAccountApiController 中的以下代码中删除当前代码

 Old - HttpContext.Current.GetOwinContext().Authentication.Challenge(new AuthenticationProperties { RedirectUri = "~/" },
           WsFederationAuthenticationDefaults.AuthenticationType);

New - HttpContext.GetOwinContext().Authentication.Challenge(new AuthenticationProperties { RedirectUri = "~/" },
           WsFederationAuthenticationDefaults.AuthenticationType);

OWIN 在附加到HttpContext 对象的IAuthenticationManager 接口中有自己的身份验证管理器版本。该对象处理用于通过站点跟踪用户的安全cookie 的创建和删除。身份 cookie 用于跟踪所有登录用户，无论他们是使用用户名和密码在本地登录还是使用 Google 等外部提供商登录。一旦用户通过身份验证，就会调用 SignIn 方法来创建 cookie。在随后的请求中，基于 OWIN 的身份子系统随后会获取 Cookie，并在用户访问您的网站时向用户授权相应的基于 IPrinciple（具有 ClaimsIdentity 的 ClaimsPrincipal）的用户。
