为 ASP.NET Identity 配置 Unity DI [英] Configure Unity DI for ASP.NET Identity

问题描述

我成功地将 Unity 用于所有常规构造函数注入，例如存储库等，但我无法让它与 ASP.NET Identity 类一起使用.设置是这样的:

I'm using Unity successfully for all regular constructor injection such as repositories etc., but I can't get it working with the ASP.NET Identity classes. The setup is this:

public class AccountController : ApiController
{
    private UserManager<ApplicationUser> _userManager { get; set; }

    public AccountController(UserManager<ApplicationUser> userManager)
    {
        if (userManager == null) { throw new ArgumentNullException("userManager"); }
        _userManager = userManager;
    }

    // ...
}

使用这些 Unity 配置:

with these configs for Unity:

unity.RegisterType<AccountController>();
unity.RegisterType<UserManager<ApplicationUser>>(new HierarchicalLifetimeManager());
unity.RegisterType<IUserStore<ApplicationUser>, UserStore<ApplicationUser>>(new HierarchicalLifetimeManager());

这与 Autofac 的其他帖子相同，例如 Ninject，但在我的情况下不起作用.错误信息是:

That's the same as other posts here for Autofac, Ninject e.g., but it doesn't work in my case. The error message is:

尝试创建类型为AccountController"的控制器时出错.确保控制器具有无参数的公共构造函数.当然是手工创作作品:

An error occurred when trying to create a controller of type 'AccountController'. Make sure that the controller has a parameterless public constructor. Manual creation works of course:

public AccountController()
    : this(new UserManager<ApplicationUser>(new UserStore<ApplicationUser>("Mongo")))
{
}

怎么了?

更新

正如@emodendroket 所建议的那样，将代码缩短为这样可以解决问题.不需要 Unity.Mvc 包.

As suggested by @emodendroket, shortening the code to this does the trick. No need for the Unity.Mvc package.

unity.RegisterType<IUserStore<IdentityUser>, 
  MyCustomUserStore>(new HierarchicalLifetimeManager());

和

public AccountController(UserManager<IdentityUser> _userManager,
  IAccountRepository _account)
{
    // ...

推荐答案

您还需要解决UserManager.以下是如何使用 UserManager 和 RoleManager 执行此操作的示例.在这个示例中，我使用了常规的 Unity 3 包，而不是派生类或引导程序之一(过去它们有一些问题).

You also need to resolve the UserManager. The following is an example how you could do it with the UserManager and the RoleManager. In this sample I use the regular Unity 3 package instead of one of the derivates or bootstrappers (had some problems with them in the past).

账户控制器

private readonly UserManager<ApplicationUser> _userManager;

private readonly RoleManager<IdentityRole> _roleManager;

public AccountController(IUserStore<ApplicationUser> userStore, IRoleStore<IdentityRole> roleStore)
{
  _userManager = new UserManager<ApplicationUser>(userStore);
  _roleManager = new RoleManager<IdentityRole>(roleStore);
}

Unity Bootstrapper

var accountInjectionConstructor = new InjectionConstructor(new IdentitySampleDbModelContext(configurationStore));
container.RegisterType<IUserStore<ApplicationUser>, UserStore<ApplicationUser>>(accountInjectionConstructor);
container.RegisterType<IRoleStore<IdentityRole>, RoleStore<IdentityRole>>(accountInjectionConstructor);
