我正在将一个大型代码库从 Ninject 迁移到 Autofac，并且正在努力处理其中一个绑定(bind)(根据我的一些调试，我认为这会导致激活错误)。

注入(inject):

Bind<ISecureDataFormat<AuthenticationTicket>>()
     .ToMethod(context =>
         {
             var owinContext = context.Kernel.Get<IOwinContext>();
             return owinContext
                    .Get<ISecureDataFormat<AuthenticationTicket>>("SecureDataFormat");
         });

Autofac(我有什么):

builder.Register(
    context => context.Resolve<IOwinContext>()
        .Get<ISecureDataFormat<AuthenticationTicket>>("SecureDataFormat"))
        .As<ISecureDataFormat<AuthenticationTicket>>();

启动.cs:

var container = RegisterIoC(app, config);

public IContainer RegisterIoC(IAppBuilder app, HttpConfiguration config)
    {
        var builder = new ContainerBuilder();
        builder = RegisterDependencies(builder);
        builder = RegisterFilters(builder, config);

        /*builder.RegisterModule<DebuggingRequestModule>();*/

        var container = builder.Build();

        DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
        config.DependencyResolver = new AutofacWebApiDependencyResolver(container);

        app.UseAutofacMiddleware(container);
        app.UseAutofacMvc();
        app.UseAutofacWebApi(config);
        app.UseWebApi(config);

        return container;
    }

更多:

builder.RegisterModule<ApiDependencyModule>().RegisterModule<AutofacWebTypesModule>();
builder.RegisterApiControllers(Assembly.GetExecutingAssembly());
builder.RegisterApiControllers(typeof(AccountController).Assembly);

(看似)关联​​的构造函数:

账户 Controller .cs:

public AccountController(ILoginService loginService,
                             IBearerTokenStore tokenStore,
                             IRememberMeCookieService rememberMeCookieService,
                             IInternalSsoChallenge ssoChallenge)
{
}

登录服务.cs:

public LoginService(IBearerTokenStore tokenStore, 
        IGrantTypeProvider grantProvider, 
        IRememberMeCookieService rememberMeCookieService)
{
}

BearerTokenCookieStore.cs:

public BearerTokenCookieStore(IOwinContext owinContext, ISecureDataFormat<AuthenticationTicket> secureDataFormat, IAppSettingsReader appSettingsReader, ICookieService cookieService)
{
}

我有一个帮助我调试的日志记录模块，这是我拥有的消息列表

最里面:

最佳答案

我们可以将 autofac 与那些 c# owin 控制反转(ninject to autofac)一起使用，一般如下所示

Startup.cs

public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {

            var config = new HttpConfiguration();
            WebApiConfig.Register(config);    

            ConfigureIoC(app, config);
            Components.Config();

            Auth.ConfigureForApi(app);

            app.UseAutofacWebApi(config);
            app.UseCors(CorsOptions.AllowAll);
            app.UseWebApi(config);
            config.EnsureInitialized();
        }

        private void ConfigureIoC(IAppBuilder app, HttpConfiguration config)
        {
            IoC.RegisterModules(
                builder =>
                {
                    builder.Register<IAuthenticationManager>(c => c.Resolve<IOwinContext>().Authentication).InstancePerRequest();
                    builder.Register<IDataProtectionProvider>(c => app.GetDataProtectionProvider()).InstancePerRequest();
                    builder.RegisterApiControllers(typeof(Startup).Assembly).PropertiesAutowired();
                },
                container =>
                {
                    config.DependencyResolver = new AutofacWebApiDependencyResolver(container);
                    app.UseAutofacMiddleware(container);

                },
                true
                );
        }

    }

WebApiConfig.cs

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

    }
}

组件配置:

public static class Components
{
    public static void Config() {
        TypeAdapterConfig.GlobalSettings.AllowImplicitDestinationInheritance = true;
        var registers = new List<IRegister>();
        registers.Add(new DtoMapping());
        registers.Add(new MappingRegistration());
        TypeAdapterConfig.GlobalSettings.Apply(registers);

        ObjectMapper.Current = new MapsterAdapter();
        DbConfiguration.Loaded += DbConfiguration_Loaded;

        var r = new Registrations();
        r.Run();
    }


    private static void DbConfiguration_Loaded(object sender, System.Data.Entity.Infrastructure.DependencyResolution.DbConfigurationLoadedEventArgs e)
    {
        e.ReplaceService<DbProviderServices>((s, k) => System.Data.Entity.SqlServer.SqlProviderServices.Instance);
    }

}

身份验证:

public class Auth
    {
        public static void ConfigureForMvc(IAppBuilder app)
        {
            app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                LoginPath = new PathString("/Login"),

                Provider = new CookieAuthenticationProvider
                {
                    OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, UserEntity, int>(
                        validateInterval: TimeSpan.FromMinutes(30),
                        regenerateIdentityCallback: (manager, user) =>
                        user.GenerateUserIdentityAsync(manager, DefaultAuthenticationTypes.ApplicationCookie),
                        getUserIdCallback: (Identity) => Identity.GetUserId<int>())
                }
            });
        }

        public static void ConfigureForApi(IAppBuilder app)
        {
            var OAuthServerOptions = new OAuthAuthorizationServerOptions()
            {
                AllowInsecureHttp = true,
                TokenEndpointPath = new PathString("/oauth2/token"),
                AccessTokenExpireTimeSpan = TimeSpan.FromMinutes(120),
                Provider = new CustomOAuthProvider(),
                AccessTokenFormat = new CustomJwtFormat(ConfigConstants.Issuer)
            };

            app.UseOAuthAuthorizationServer(OAuthServerOptions);

            app.UseJwtBearerAuthentication(
                new JwtBearerAuthenticationOptions
                {
                    AuthenticationMode = AuthenticationMode.Active,
                    AllowedAudiences = new[] { ConfigConstants.AudienceId },
                    IssuerSecurityTokenProviders = new IIssuerSecurityTokenProvider[]
                    {
                        new SymmetricKeyIssuerSecurityTokenProvider(ConfigConstants.Issuer, ConfigConstants.AudienceSecurityKey)
                    }
                });

        }
    }
