从外部访问 User.Identity 和 Claims

Question

我正在尝试使用 OpenID Connect 构建 SSO(.net core) 服务，这将是 Webforms 应用程序和服务提供者之间的一个层。我创建了一些端点来检查用户是否通过身份验证并从服务中获取用户声明。当我从浏览器调用这些端点时，我能够获得正确的结果。但是，当我从网站（使用 HttpWebRequest）调用它们时。User.Identity总是空的。我用来检查用户是否通过身份验证的端点如下所示：[HttpGet][Route("IsAuthenticated")]public IActionResult IsAuthenticated(){    return Json(User.Identity.IsAuthenticated);}或者获取访问令牌：[HttpGet][Route("access_token")]public async Task<IActionResult> AccessToken(){    var tokenResult = await HttpContext.GetTokenAsync("access_token");    return Json(tokenResult);}我的启动 ConfigureServices 看起来像这样：var OIDCConfiguration = new OIDCSettings(){    Authority = Configuration["OIDCSettings:Authority"],    ClientId = Configuration["OIDCSettings:ClientId"],    ClientSecret = Configuration["OIDCSettings:ClientSecret"],    CallbackPath = Configuration["OIDCSettings:CallbackPath"],    UserInfoEndpoint = Configuration["OIDCSettings:UserInfoEndpoint"]};services.AddAuthentication(options => {    options.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;    options.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;    options.DefaultChallengeScheme = "oidc";}).AddCookie(CookieAuthenticationDefaults.AuthenticationScheme).AddOpenIdConnect("oidc", options => {    options.Authority = OIDCConfiguration.Authority;    options.ClientId = OIDCConfiguration.ClientId;    options.ClientSecret = OIDCConfiguration.ClientSecret;    options.CallbackPath = new PathString(OIDCConfiguration.CallbackPath);    options.ResponseType = OpenIdConnectResponseType.Code;    options.GetClaimsFromUserInfoEndpoint = true;    options.Scope.Add("openid emailAddress");    options.AuthenticationMethod = OpenIdConnectRedirectBehavior.RedirectGet;    options.SaveTokens = true;});为了启动中间件，我使用了 ChallengeResult 对象。我是 OpenID Connect 和中间件架构的初学者，所以我不确定我缺少什么，或者我的架构是否正确。
