如何构造ISecureDataFormat< AuthenticationTicket>.团结一致 [英] How to construct ISecureDataFormat<AuthenticationTicket> with unity

问题描述

我的webapi帐户控制器上的构造函数如下:

I have consturctor on my webapi account controller looking like that:

public AccountController(ApplicationUserManager userManager, ISecureDataFormat<AuthenticationTicket> accessTokenFormat)
{
   _userManager = userManager;
   AccessTokenFormat = accessTokenFormat;
}

但是Unity无法构造ISecureDataFormat<AuthenticationTicket>，因为构造函数要等到我取下第二个参数后才能工作.

But Unity is not able to consruct the ISecureDataFormat<AuthenticationTicket>because the constructor is not working untill I taking off the second param.

public AccountController(ApplicationUserManager userManager)
{
   _userManager = userManager;
}

如何使用Unity构造第二个参数? 我的Unityconfig:

How I can construct the second param with Unity? My Unityconfig:

.RegisterType<DbContext, ApplicationDbContext>(new HierarchicalLifetimeManager())
.RegisterType<UserManager<ApplicationUser, int>, ApplicationUserManager>()                
.RegisterType<ApplicationDbContext>(new HierarchicalLifetimeManager())
.RegisterType<ApplicationUserManager>()

.RegisterType<ISecureDataFormat<AuthenticationTicket>, SecureDataFormat<AuthenticationTicket>>()
.RegisterType<ITextEncoder, Base64UrlTextEncoder>()
.RegisterType<IDataSerializer<AuthenticationTicket>, TicketSerializer>()
//.RegisterType<IDataProtector>(() => new DpapiDataProtectionProvider().Create("ASP.NET Identity"))

.RegisterType<IUserStore<ApplicationUser, int>, CustomUserStore>(new InjectionConstructor(typeof(ApplicationDbContext)))
.RegisterType<IAuthenticationManager>(new InjectionFactory(o => HttpContext.Current.GetOwinContext().Authentication))
.RegisterType<IOwinContext>(new InjectionFactory(o => HttpContext.Current.GetOwinContext()))
.RegisterType<IRepository, Repository>();

推荐答案

您尚未在UnityContainer中注册类型IDataProvider (我不知道为什么在统一配置中将其注释掉)，但是SecureDataFormat<AuthenticationTicket>构造函数需要这样做.

You haven't registered type IDataProvider within UnityContainer (I don't knows why you comment out that within your unity config) however SecureDataFormat<AuthenticationTicket> constructor requires that.

public class SecureDataFormat<TData> : ISecureDataFormat<TData>
{
    public SecureDataFormat(IDataSerializer<TData> serializer, IDataProtector protector, ITextEncoder encoder)

我也面临着同样的问题.以下统一配置为我解决了问题

I was also facing the same issue. Following unity config resolved issue for me

container.RegisterType<ITextEncoder, Base64UrlTextEncoder>();
container.RegisterType<IDataSerializer<AuthenticationTicket>, TicketSerializer>();
container.RegisterInstance(new DpapiDataProtectionProvider().Create("ASP.NET Identity"));
container.RegisterType<ISecureDataFormat<AuthenticationTicket>, SecureDataFormat<AuthenticationTicket>>();
