我正在将一个大型代码库从Ninject迁移到Autofac，并且正在努力解决其中一个绑定问题（我认为这会导致基于我的一些调试的激活错误）。
Ninject：
Bind<ISecureDataFormat<AuthenticationTicket>>()
.ToMethod(context =>
{
var owinContext = context.Kernel.Get<IOwinContext>();
return owinContext
.Get<ISecureDataFormat<AuthenticationTicket>>("SecureDataFormat");
});
Autofac（我拥有的）：
builder.Register(
context => context.Resolve<IOwinContext>()
.Get<ISecureDataFormat<AuthenticationTicket>>("SecureDataFormat"))
.As<ISecureDataFormat<AuthenticationTicket>>();
Startup.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);
（貌似）相关的构造函数：
AccountController.cs：
public AccountController(ILoginService loginService,
IBearerTokenStore tokenStore,
IRememberMeCookieService rememberMeCookieService,
IInternalSsoChallenge ssoChallenge)
{
LoginService.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，这是我有的消息列表

我们可以将autofac与以下c＃OWIN控制反转（注入到autofac ）一起使用
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)
}
});
}
}
