配置统一DI为ASP.NET身份 [英] Configure Unity DI for ASP.NET Identity

问题描述

我使用Unity成功为所有常规构造注射，如仓库等，但我不能让它与ASP.NET身份类的工作。该设置是这样的：

 公共类的AccountController：ApiController
{
    私人的UserManager＆LT; ApplicationUser＆GT; _userManager {搞定;组; }    公众的AccountController（的UserManager＆LT; ApplicationUser＆GT;的UserManager）
    {
        如果（的UserManager == NULL）{抛出新的ArgumentNullException（的UserManager）; }
        _userManager =的UserManager;
    }    // ...
}
 

这些CONFIGS团结：

  unity.RegisterType＆LT;＆的AccountController GT;（）;
unity.RegisterType＆所述;的UserManager＆下; ApplicationUser＆GT;＆GT;（新HierarchicalLifetimeManager（））;
unity.RegisterType＆所述; IUserStore＆下; ApplicationUser＆gt;中UserStore＆所述; ApplicationUser＆GT;＆GT;（新HierarchicalLifetimeManager（））;
 

这是一样在这里的其他职位Autofac，Ninject例如，但它并不在我的情况下工作。错误消息是：

  

试图创建类型的控制器的AccountController时发生错误。确保控制器具有一个无参数公共构造函数。
  手动创作的作品，当然：

 公开的AccountController（）
    ：这（新的UserManager＆LT; ApplicationUser＆GT;（新UserStore＆LT; ApplicationUser＆GT;（蒙戈）））
{
}
 

怎么了？

更新

由于建议的@emodendroket，缩短了code到这样做的伎俩。不需要对Unity.Mvc包

  unity.RegisterType＆LT; IUserStore＆LT; IdentityUser＆gt;中
  MyCustomUserStore＆GT;（新HierarchicalLifetimeManager（））;
 

和

 公开的AccountController（的UserManager＆LT; IdentityUser＆GT; _userManager，
  IAccountRepository _account）
{
    // ...
 

解决方案

您还需要解决在的UserManager 。下面是一个例子中，你如何与在的UserManager 做到这一点，在 RoleManager 。在这个示例中，我使用常规的统一3包，而不是衍生物或bootstrappers之一（在过去的一些问题与他们）。

的AccountController

 私人只读的UserManager＆LT; ApplicationUser＆GT; _userManager;私人只读RoleManager＆LT; IdentityRole＆GT; _roleManager;公众的AccountController（IUserStore＆LT; ApplicationUser＆GT; userStore，IRoleStore＆LT; IdentityRole＆GT; Rolestore的）
{
  _userManager =新的UserManager＆LT; ApplicationUser＆GT;（userStore）;
  _roleManager =新RoleManager＆LT; IdentityRole＆GT;（Rolestore的）;
}
 

团结引导程序

  VAR accountInjectionConstructor =新InjectionConstructor（新IdentitySampleDbModelContext（configurationStore））;
container.RegisterType＆所述; IUserStore＆下; ApplicationUser＆gt;中UserStore＆所述; ApplicationUser＆GT;＆GT;（accountInjectionConstructor）;
container.RegisterType＆所述; IRoleStore＆下; IdentityRole＆gt;中Rolestore的＆所述; IdentityRole＆GT;＆GT;（accountInjectionConstructor）;
 

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;
    }

    // ...
}

with these configs for Unity:

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

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:

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")))
{
}

What's wrong?

UPDATE

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());

and

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

解决方案

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).

AccountController

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);
