我正在将大型代码库从ninject迁移到autoFac，并在我认为基于我的某些调试的一种绑定上挣扎。
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);
(看似(关联的构造函数：
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)
{
}
我有一个可帮助我调试的记录模块，这是我拥有的消息列表：
Resolving _______.Login.Controllers.AccountController
--Resolving _______.ApiGateway.Services.Auth.LoginService
----Resolving _______.ApiGateway.Security.OAuth.BearerTokenCookieStore

从ninject到autoFac的迁移似乎是正确的，但是 ISecureDataFormat<AuthenticationTicket>接口的绑定可能无法正常工作，导致某些依赖项的激活误差。基于调试消息，BearerTokenCookieStore类无法解决此依赖关系。
在Ninject版本中，ISecureDataFormat<AuthenticationTicket>绑定到检索IOwinContext实例的方法，并使用它来解析ISecureDataFormat<AuthenticationTicket>命名为" SecuredataFormat。"。但是，在AUTOFAC版本中，ISecureDataFormat<AuthenticationTicket>实例是使用IOwinContext实例直接解决的，但没有提供名称。
可能在AutoFac容器中未正确注册ISecureDataFormat<AuthenticationTicket>。要解决此问题，您可以尝试使用命名扩展方法明确注册命名实例：
builder.Register(context =>
context.Resolve<IOwinContext>()
.Get<ISecureDataFormat<AuthenticationTicket>>("SecureDataFormat"))
.Named<ISecureDataFormat<AuthenticationTicket>>("SecureDataFormat");
builder.Register(context =>
context.ResolveNamed<ISecureDataFormat<AuthenticationTicket>>("SecureDataFormat"))
.As<ISecureDataFormat<AuthenticationTicket>>();
然后，在BearerTokenCookieStore构造函数中，您可以解决这样的命名实例：
public BearerTokenCookieStore(
IOwinContext owinContext,
[Named("SecureDataFormat")] ISecureDataFormat<AuthenticationTicket> secureDataFormat,
IAppSettingsReader appSettingsReader,
ICookieService cookieService)
{ }
这应该确保BearerTokenCookieStore类正确解析ISecureDataFormat<AuthenticationTicket>名为"SecureDataFormat"的CC_12，并且需要其他需要它的依赖项使用。
我们可以将autoFac与control的那些c＃owin倒置( ninject to autoFac (一样，如下
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)
}
});
}
}
