将IOC容器与IdentityFactory中间件一起使用 [英] using IOC container with IdentityFactory Middleware

问题描述

我试图了解此处解释的UserManagerFactory中间件

I am trying to understand the UserManagerFactory middleware explained here per request lifetime management for usermanager.

我创建了这个类，该类是通过启动配置"方法调用的

I created this class which I am calling from the Startup Configuration method

public class CustomUserManagerProvider
{
    public static CustomUserStore<CustomUser> CreateCustomUserStore()
    {
        return new CustomUserStore<CustomUser>(/*Need to inject dependencies here*/);
    }

    public static CustomUserManager CreateCustomUserManager(IdentityFactoryOptions<CustomUserManager> options,
        IOwinContext context)
    {
        return new CustomUserManager(context.Get<CustomUserStore<CustomUser>>());
    }
}

和启动配置

public void Configuration(IAppBuilder app)
    {
        app.CreatePerOwinContext(CustomUserManagerProvider.CreateCustomUserStore);
        app.CreatePerOwinContext<IngramUserManager>(CustomUserManagerProvider.CreateCustomUserManager);
        ////....Other things
    }

现在，我的CustomUserStore有一些依赖关系，我想在构造函数中注入这些依赖关系.

Now, My CustomUserStore has some dependencies which I want to inject in the constructor.

IOC容器的组合根知道如何解决这些依赖关系.

The composition root of the IOC container knows how to resolve these dependencies.

如何使CustomUserManagerProvider DI容器知道(如果有意义)...

How do I make the CustomUserManagerProvider DI container aware(If that makes sense)...

虽然有效

public static CustomUserStore<CustomUser> CreateCustomUserStore()
    {
        var dependency = DependencyResolver.Current.GetService<ISomeDependency>();          
        return new CustomUserStore<CustomUser>(dependency);
    }

但是，我试图避免使用服务定位器(反)模式.这是我唯一的选择，这还对吗?

But, I was trying to avoid the service locator (anti)pattern. Is this my only option, Is this even right??

我正在使用Ninject.

I am using Ninject.

我不能在组合根目录的requestScope中创建一个UserManager并注入到控制器中，

Cant I just create a UserManager in requestScope in the composition root and inject into the controllers, wont that be the same thing?

在网络应用中，CreatePerOwinContext是否与创建InRequestScope相同?

In a web app, is CreatePerOwinContext same as creating InRequestScope?

推荐答案

是的，您可以根据需要将UserManager以不同的方式注入到控制器中，不需要使用CreatePerOwinContext/IdentityFactoryMiddleware.

Yes, you can inject the UserManager into your controllers a different way if you like, there's nothing that requires using the CreatePerOwinContext/IdentityFactoryMiddleware.
