带有autofac的IdentityServer3

Question

我正在尝试将 IdentityServer3 实施到使用 Autofac 的现有项目中。我遇到的问题是，当我设置我的自定义服务时，如果我运行我的项目并尝试验证我得到这个错误：

"An error occurred when trying to create a controller of type 'TokenEndpointController'. Make sure that the controller has a parameterless public constructor."

现在我知道这是服务未正确设置时的一般性 autofac 错误。该错误实际上抱怨我的自定义 UserService 声明：

None of the constructors found with 'Autofac.Core.Activators.Reflection.DefaultConstructorFinder' on type 'Business.IdentityServer.IdentityServerUserService' can be invoked with the available services and parameters: Cannot resolve parameter 'Business.Providers.IUserProvider userProvider' of constructor 'Void .ctor(Business.Providers.IUserProvider)'.

现在，在我开始使用 IdentityServer3 之前，我已经有了一个 UserProvider，它在 autofac 中的设置如下：

builder.RegisterType<DatabaseContext>().As<DbContext>().InstancePerDependency();
builder.RegisterType<UserProvider>().As<IUserProvider>().InstancePerDependency();

这之前是有效的，所以我知道 UserProvider 实际上有它的所有依赖项。

我的用户服务看起来像这样：

public class IdentityServerUserService : UserServiceBase
{
    private readonly IUserProvider _userProvider;

    public IdentityServerUserService(IUserProvider userProvider)
    {
        _userProvider = userProvider;
    }

    public override async Task AuthenticateLocalAsync(LocalAuthenticationContext context)
    {
        var user = await _userProvider.FindAsync(context.UserName, context.Password);

        if (user != null && !user.Disabled)
        {
            // Get the UserClaims

            // Add the user to our context
            context.AuthenticateResult = new AuthenticateResult(user.Id, user.UserName, new List<Claim>());
        }
    }
}

有谁知道我该如何解决这个问题？

这是因为我配置工厂的方式。我现在是这样的：

    private static IdentityServerServiceFactory Configure(this IdentityServerServiceFactory factory, CormarConfig config)
    {
        var serviceOptions = new EntityFrameworkServiceOptions { ConnectionString = config.SqlConnectionString };
        factory.RegisterOperationalServices(serviceOptions);
        factory.RegisterConfigurationServices(serviceOptions);

        factory.CorsPolicyService = new Registration<ICorsPolicyService>(new DefaultCorsPolicyService { AllowAll = true }); // Allow all domains to access authentication
        factory.Register<DbContext>(new Registration<DbContext>(dr => dr.ResolveFromAutofacOwinLifetimeScope<DbContext>()));
        factory.UserService = new Registration<IUserService>(dr => dr.ResolveFromAutofacOwinLifetimeScope<IUserService>());
        factory.ClientStore = new Registration<IClientStore>(dr => dr.ResolveFromAutofacOwinLifetimeScope<IClientStore>());
        factory.ScopeStore = new Registration<IScopeStore>(dr => dr.ResolveFromAutofacOwinLifetimeScope<IScopeStore>());

        return factory;
    }

我的用户服务还是一样的，所以一切正常。
