';SignInScheme';必须提供选项

我正在创建一个仅使用Facebook/Google身份验证的ASP.NET 5 MVC 6应用程序。我还试图在没有整个ASP.NET Identity的情况下使用cookie中间件——下面是本文:https://docs.asp.net/en/latest/security/authentication/cookie.html

因此,我从一个没有身份验证的空白应用程序开始,然后添加了Microsoft.AspNet.authentication.Cookies和Microsoft.AspNet.Authentications.Facebook NuGet包,以便采用一种非常简约的方法,不包含任何我不需要的内容。

我在Startup.cs中的Configure中添加了以下代码,但我得到了"必须提供SignInScheme选项"错误。知道我错过了什么吗?

app.UseCookieAuthentication(options =>
            {
                options.AuthenticationScheme = "MyCookieMiddlewareInstance";
                options.LoginPath = new PathString("/Accounts/Login/");
                options.AccessDeniedPath = new PathString("/Error/Unauthorized/");
                options.AutomaticAuthenticate = true;
                options.AutomaticChallenge = true;
            });
            app.UseFacebookAuthentication(options =>
            {
                options.AppId = "myFacebookAppIdGoesHere";
                options.AppSecret = "myFacebookAppSecretGoesHere";
            });

';SignInScheme';必须提供选项

如您看到的错误消息所示,您需要在Facebook中间件选项中设置options.SignInScheme

app.UseFacebookAuthentication(options => {
    options.AppId = "myFacebookAppIdGoesHere";
    options.AppSecret = "myFacebookAppSecretGoesHere";
    // This value must correspond to the instance of the cookie
    // middleware used to create the authentication cookie.
    options.SignInScheme = "MyCookieMiddlewareInstance";
});

或者,您也可以从ConfigureServices全局设置它(它将配置每个身份验证中间件,这样您就不必设置options.SignInScheme):

public void ConfigureServices(IServiceCollection services) {
    services.AddAuthentication(options => {
        // This value must correspond to the instance of the cookie
        // middleware used to create the authentication cookie.
        options.SignInScheme = "MyCookieMiddlewareInstance";
    });
}
