c# - ASP.Net Core 1.1 MVC 应用程序中的 401 未经 IdentityServer3 授权

Question

去年我在多个应用程序中使用 IdentityServer3。所有这些应用程序都在 .Net Framework 4.5 上运行。现在我已经创建了 ASP.Net Core MVC (1.1) 应用程序，我想使用我的 IdentityServer 来保护该应用程序。但我正在努力让它发挥作用。我收到 401 未经授权的错误。

这是我正在使用的配置:

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    AuthenticationScheme = "Cookies",
    AutomaticAuthenticate = true,
    AutomaticChallenge = true
});

JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();

app.UseOpenIdConnectAuthentication(new OpenIdConnectOptions
{
    AuthenticationScheme = "oidc",
    SignInScheme = "Cookies",

    Authority = "<IdentityServer URL>",
    RequireHttpsMetadata = false,

    ClientId = "clientid",

    ResponseType = "token id_token",
    Scope = { "openid","email"},

    SaveTokens = true,

    PostLogoutRedirectUri = "http://localhost:29995/",

    Scope = { "openid, email" },
    ResponseType = "id_token token",

    Events = new OpenIdConnectEvents()
    {
        OnTokenValidated = (context) =>
        {
            //my code
            return Task.FromResult(0);
        }
    }
});

当我尝试访问安全页面时，我收到 401 Unauthorized。它甚至不会进入 IdentityServer 的登录页面。

尝试访问的 URL

https://<IdentityServerUrl>/connect/authorize?client_id=APITestweb&redirect_uri=http://localhost:29995/signin-oidc&response_type=code id_token&scope=openid profile email&response_mode=form_post&nonce=<data>&state=<data>

客户端 ID 和 URL 已正确配置。我尝试创建另一个 ASP.Net MVC 应用程序(不是 ASP.Net Core)，并且使用相同的配置信息可以正常工作。

请帮忙。

如果您使用的是 Microsoft.AspNetCore.Authentication.OpenIdConnect v.1.1.0，目前存在一个错误(或者人们可能会称之为重大更改)。

对我来说，1.0.0 软件包仍然有效，因此请检查降级是否有帮助。
