[英]This resolve operation has already ended. Autofac, Automapper & IMemberValueResolver
[英]Autofac, resolve operation ended
我剛開始使用 Autofac 並嘗試連接 Asp.Net Identity,但失敗了。 我以為我一切正常,但我卡住了,需要幫忙。
UserManager 通過構造函數注入。
private readonly ApplicationUserManager UserManager;
private readonly ApplicationSignInManager SignInManager;
public UserController(IDocumentSession documentSession, ApplicationUserManager userManager, ApplicationSignInManager signInManager) : base(documentSession) {
UserManager = userManager;
SignInManager = signInManager;
}
當我到達這個異步調用時,我的 UserController.cs 出現了問題。
var user = await UserManager.FindAsync(model.Email, model.Password);
此解析操作已結束。 使用 lambda 注冊組件時,無法存儲 lambda 的 IComponentContext 'c' 參數。 相反,要么從“c”再次解析 IComponentContext,要么解析基於 Func<> 的工廠以從中創建后續組件。
問題是我得到了一個非常明確的信息,但我不知道如何繼續; 我應該以不同的方式注冊我的 ApplicationUserManager 嗎?
我已經像這樣設置了我的容器。 我希望有人可以看看。
public static void RegisterContainer(IAppBuilder app)
{
// Autofac container ..
var builder = new ContainerBuilder();
// Register all MVC Controllers
builder.RegisterControllers(Assembly.GetExecutingAssembly());
// Register all services that implement the Module interface
builder.RegisterAssemblyModules(BuildManager.GetReferencedAssemblies().Cast<Assembly>().ToArray());
// Register the DocumentStore instance
builder.Register(context => new RavenDocumentStoreFactory()
.FindOrCreate())
.As<IDocumentStore>()
.SingleInstance();
// Multi tenancy part
var tenantIdStrategy = new TenantIdStrategy();
var multitenantContainer = new MultitenantContainer(tenantIdStrategy, builder.Build());
var tenantIds = new[]
{
"subdomain1.tickets",
"localhost"
};
foreach (var tenantId in tenantIds)
{
var databaseName = $"ticketTenant-{tenantId.Replace('.', '_')}";
multitenantContainer.ConfigureTenant(tenantId, b =>
{
// Init RavenDB
b.Register(context => new RavenDocumentSessionFactory(databaseName))
.InstancePerTenant()
.AsSelf();
// Session per request
b.Register(context => context.Resolve<RavenDocumentSessionFactory>()
.FindOrCreate(context.Resolve<IDocumentStore>()))
.As<IDocumentSession>()
.InstancePerRequest()
.OnRelease(x =>
{
x.SaveChanges();
x.Dispose();
});
// ASP.Net Identity Registrations
b.Register(context => new UserStore<User>(context.Resolve<IDocumentSession>))
.AsImplementedInterfaces()
.InstancePerRequest()
.OnRelease(x =>
{
x.Dispose();
});
b.Register<IdentityFactoryOptions<ApplicationUserManager>>(c =>
new IdentityFactoryOptions<ApplicationUserManager>() {
DataProtectionProvider = new Microsoft.Owin.Security.DataProtection.DpapiDataProtectionProvider("ApplicationName")
});
b.RegisterType<ApplicationUserManager>().AsSelf().InstancePerRequest();
b.RegisterType<ApplicationSignInManager>().AsSelf().InstancePerRequest();
b.Register<IAuthenticationManager>(c => HttpContext.Current.GetOwinContext().Authentication).InstancePerRequest();
b.Register<IDataProtectionProvider>(c => app.GetDataProtectionProvider()).InstancePerRequest();
});
}
// Register in Owin
app.UseAutofacMiddleware(multitenantContainer);
app.UseAutofacMvc();
// Dependency Resolver to Autofac
DependencyResolver.SetResolver(new AutofacDependencyResolver(multitenantContainer));
}
}
我解決了我自己的問題,但老實說......我不知道我是如何解決這個問題的。 這只是反復試驗。 這是新的配置; 舊部分已注釋。
它甚至不需要 Owin 部分的最后一個 Register ......甚至評論說它現在看起來工作得很好。
