如何将ASP Net Identity转换为OpenId Connect

Question

我有一个使用.NET Framework 4.6 AspNetIdentity的项目，我正在尝试升级它以使用OpenIdConnect。有没有人使用.NET Framework 4.6取代ASPNetIdentity和OpenIdConnect？

我查看了owin示例和一些.NET核心2.0快速入门示例，例如these，但它们似乎与我想要完成的内容不兼容。

我正在尝试专门添加类似于以上代码片段中的以下代码片段：

services.AddAuthentication(options =>
{
    options.DefaultScheme = "Cookies";
    options.DefaultChallengeScheme = "oidc";
});
    .AddCookie("Cookies")
    .AddOpenIdConnect("oidc", options =>
    {
        options.SignInScheme = "Cookies";

        options.Authority = "http://xxx.xxx.xxx.xxx:5000";
        options.RequireHttpsMetadata = false;

        options.ClientId = "foo";
        options.ClientSecret = "secret";
        options.ResponseType = "code id_token";

        options.SaveTokens = true;
        options.GetClaimsFromUserInfoEndpoint = true;

        options.Scope.Add("api1");
        options.Scope.Add("offline_access");
    });

我需要类似于我的Startup.cs文件的ConfigureServices（）方法中的IServiceCollection服务参数的AddAuthentication（）扩展，以允许客户端通过IdentityServer4登录。

在.net框架中，您可以使用Microsoft.Owin.Security.OpenIdConnect文件中的Startup.Auth.cs库配置OpenID Connect，例如：

public void ConfigureAuth(IAppBuilder app)
    {
        app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);

        app.UseCookieAuthentication(new CookieAuthenticationOptions());

        app.UseOpenIdConnectAuthentication(
            new OpenIdConnectAuthenticationOptions
            {
                ClientId = clientId,
                Authority = Authority,
                PostLogoutRedirectUri = redirectUri,
                RedirectUri = redirectUri,

                Notifications = new OpenIdConnectAuthenticationNotifications()
                {
                    //
                    // If there is a code in the OpenID Connect response, redeem it for an access token and refresh token, and store those away.
                    //
                    AuthenticationFailed = OnAuthenticationFailed
                }

            });
    }

    private Task OnAuthenticationFailed(AuthenticationFailedNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> context)
    {
        context.HandleResponse();
        context.Response.Redirect("/Home/Error?message=" + context.Exception.Message);
        return Task.FromResult(0);
    }

谢谢你的回复！我会说@Nan Yu可能得到了最接近我提出的解决方案的答案，但我想我会分享我最终在Startup.cs文件的Configure（）方法中得到的结果。

using Microsoft.AspNetCore.Authentication.OpenIdConnect;
using Microsoft.IdentityModel.Protocols.OpenIdConnect;
...
var openidOptions = new OpenIdConnectOptions(authenticationScheme)
{
    ClientSecret = secret,
    AutomaticAuthenticate = true,
    SignInScheme = "Identity.External",
    Authority = identityServerAddress,
    ClientId = clientId,
    RequireHttpsMetadata = true,
    ResponseType = OpenIdConnectResponseType.CodeIdToken,
    AutomaticChallenge= true,
    GetClaimsFromUserInfoEndpoint = true,
    SaveTokens = true,
    Events = new OpenIdConnectEvents
    {
        OnRemoteSignOut = async remoteSignOutContext =>
        {
            remoteSignOutContext.HttpContext.Session.Clear();
        },
    },
};
openidOptions.Scope.Clear();
openidOptions.Scope.Add("openid");
app.UseOpenIdConnectAuthentication(openidOptions);

将此添加到我的.NET Framework 4.6客户端最终让我成功与我的.NET Core 2.0 Identity Server通信！我感谢所有试图帮助的人:)
