这是我的入门班

public class Startup

    public Startup(IConfiguration configuration)

        services.AddDbContext<ConfArchDbContext>(options =>
            options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"),
                assembly => 
                   assembly.MigrationsAssembly(typeof(ConfArchDbContext).Assembly.FullName)));

               options.Cookie.IsEssential = true;
               //options.Cookie.SameSite = SameSiteMode.None;
           })

}

这是我的控制器，在行中抛出错误：var result = await HttpContext.AuthenticateAsync(

public class AccountController : Controller
{
    private readonly IUserRepository userRepository;

    public AccountController(IUserRepository userRepository)
    {
        this.userRepository = userRepository;
    }

    // This method must be anonymous to allow access to not logged users
    [AllowAnonymous]

        var principal = new ClaimsPrincipal(identity);

        await HttpContext.SignInAsync(

            principal,
            new AuthenticationProperties { IsPersistent = 
                 model.RememberLogin,

Answer 1

我想出了答案，在配置服务代码中应该是这样：

// Demand authentication in the whole application
services.AddControllersWithViews(o => o.Filters.Add(new 
AuthorizeFilter()));

services.AddScoped<IConferenceRepository, ConferenceRepository>();
services.AddScoped<IProposalRepository, ProposalRepository>();
services.AddScoped<IAttendeeRepository, AttendeeRepository>();
services.AddScoped<IUserRepository, UserRepository>();

services.AddDbContext<ConfArchDbContext>(options =>


 options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"),
        assembly => 
 assembly.MigrationsAssembly(typeof(ConfArchDbContext).Assembly.FullName)));

services.AddAuthentication(o => {
    o.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    //o.DefaultChallengeScheme = GoogleDefaults.AuthenticationScheme;
})
.AddCookie()
.AddCookie(ExternalAuthenticationDefaults.AuthenticationScheme)
.AddGoogle(o =>
{   // ClienteId and Secret to authenticate the user from Google          
    o.SignInScheme = 
        ExternalAuthenticationDefaults.AuthenticationScheme;
    o.ClientId = Configuration["Authentication:Google:ClientId"];
    o.ClientSecret = 
       Configuration["Authentication:Google:ClientSecret"];
});
