Question

我们有一个全新的ASP.NET Core网站，目的是升级旧的ASP.NET Framework网站。那时我们使用DotNetOpenAuth进行OpenID登录，现在我们正尝试在ASP.NET Core中进行复制。

我们已经可以将网站重定向到OpenID提供程序，并且能够登录，但是在回拨到我们的网站时会引发异常：

InvalidOperationException: No authenticationScheme was specified, and there was no DefaultSignInScheme found.

我找不到完整的示例，这确实有助于我理解整个过程。我从各种来源整理了以下内容...

在启动公司的ConfigureServices中：

            services.AddDistributedMemoryCache();

            services.AddSession(options =>
            {
                // Set a short timeout for easy testing.
                options.IdleTimeout = TimeSpan.FromSeconds(10);
                options.Cookie.HttpOnly = true;
                options.Cookie.SecurePolicy = CookieSecurePolicy.Always; //require https
                // Make the session cookie essential
                options.Cookie.IsEssential = true;
            });

            services.Configure<CookiePolicyOptions>(options =>
            {
                // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                options.CheckConsentNeeded = context => false; //true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });

            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

            services.AddSimpleInjector(_simpleInjectorContainer, options =>
            {
                // AddAspNetCore() wraps web requests in a Simple Injector scope.
                options.AddAspNetCore()
                    // Ensure activation of a specific framework type to be created by
                    // Simple Injector instead of the built-in configuration system.
                    .AddControllerActivation()
                    .AddViewComponentActivation();
                //.AddPageModelActivation()
                //.AddTagHelperActivation();
            });

            services.AddAuthentication(options =>
            { /* Authentication options */
              //options.DefaultAuthenticateScheme = "Steam";

            })
                .AddSteam(options =>
                {
                });

由于没有使用ASP.NET Core的经验，我盲目地尝试将{Steam}分配给DefaultAuthenticateScheme内的AddAuthentication，但这会引发一个错误，表明它无法自我调用。

我们一直在使用默认的Home控制器作为测试平台：

    [HttpGet("~/signin")]
    public IActionResult SignIn()
    {
        // Instruct the OIDC client middleware to redirect the user agent to the identity provider.
        // Note: the authenticationType parameter must match the value configured in Startup.cs
        return Challenge(new AuthenticationProperties
        {
            RedirectUri = Url.Action("HandleSteamLogin", "Home"),
        }, "Steam");
    }

    public async Task<IActionResult> HandleSteamLogin()
    {
        //Everything in this method is marked as obsolete, so it's a poor example.  I guess it's from an older version of ASP.NET Core?

        var claimsPrincipal = await HttpContext.Authentication.AuthenticateAsync("ExternalCookie");

        //do something the the claimsPrincipal, possibly create a new one with additional information
        //create a local user, etc

        await HttpContext.Authentication.SignInAsync("MainCookie", claimsPrincipal);
        await HttpContext.Authentication.SignOutAsync("ExternalCookie");
        return Redirect("~/");
    }

我什至可以在异常数据中看到，我们正在获取必要的登录信息，但是我确实需要一个完整的示例以使我能够理解。
