实体框架 – ASP.net身份,IoC和共享DbContext

由于ASP.NET Identity使用的IdentityDbContext继承自DbContext,您可以简单地创建自己的继承自IdentityDbContext的实现,如此

public class ApplicationContext : IdentityDbContext<ApplicationUser>
{
     //additional DbSets
    public DbSet<OtherEntity> OtherEntities { get; set; } 
}

public class ApplicationUser : IdentityUser
{
    //any custom properties you want for your user.
}

public class OtherEntity
{
    [Key]
    public int Id { get; set; }
}

现在就使用IoC而言,从统一的角度来看,我就像这样注册UserStore的一个实例

public static void RegisterTypes(IUnityContainer container)
{
    container.RegisterType<IUserStore<ApplicationUser>,UserStore<ApplicationUser>>(new InjectionConstructor(typeof(ApplicationContext)));
}

然后围绕用户管理器创建一个包装器

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    public ApplicationUserManager(IUserStore<ApplicationUser> store) : base(store)
    {
    }
}

并在我需要用户经理的任何地方注入.

对于OWIN管道,您需要通过容器实例化OAuthAuthorizationProvider,就像这样.

container.RegisterType<IOAuthAuthorizationServerProvider,ApplicationOAuthProvider>(new InjectionConstructor("self",typeof(ApplicationUserManager)));

然后,例如在WebApi中,您只需要在启动时从容器中获取实例.

static Startup()
        {
            OAuthOptions = new OAuthAuthorizationServerOptions
            {
                TokenEndpointPath = new PathString("/Token"),Provider = (IOAuthAuthorizationServerProvider)GlobalConfiguration.Configuration.DependencyResolver.GetService(typeof(IOAuthAuthorizationServerProvider)),AccessTokenExpireTimeSpan = TimeSpan.FromDays(5),AllowInsecureHttp = true,RefreshTokenProvider = new SimpleRefreshTokenProvider()
            };
        }
