在.Net Core中创建PerOwinContext

Question

如何在.net Core中创建这样的owin上下文，以便可以使用用户和角色管理器？

 public void ConfigureAuth(IAppBuilder app)
    {
        // Configure the db context, user manager and signin manager to use a single instance per request
        //app.CreatePerOwinContext(ApplicationDbContext.Create);

        app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
        app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
        app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);


   }

并在Controller中使用，如

  private ApplicationSignInManager _signInManager;
    private ApplicationUserManager _userManager;
    private ApplicationRoleManager _roleManager;

    public UsersAdminController()
    {
    }

    public UsersAdminController(ApplicationUserManager userManager, ApplicationSignInManager signInManager, ApplicationRoleManager roleManager)
    {
        UserManager = userManager;
        SignInManager = signInManager;
        RoleManager = roleManager;
    }


  public ApplicationSignInManager SignInManager
    {
        get
        {
            return _signInManager ?? HttpContext.GetOwinContext().Get<ApplicationSignInManager>();
        }
        private set
        {
            _signInManager = value;
        }
    }

    public ApplicationUserManager UserManager
    {
        get

        {
     //GetOwinContext is not available in .Net Core
            return _userManager ?? HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>();
        }
        private set
        {
            _userManager = value;
        }
    }

     public ApplicationRoleManager RoleManager
    {
        get
        {
            return _roleManager ?? HttpContext.GetOwinContext().GetUserManager<ApplicationRoleManager>();
        }
        private set
        {
            _roleManager = value;
        }
    }

我尝试过this，但没有得到想要的结果。

这是ASP.NET MVC 5的代码，不是核心。尽管两个名称中都有“ ASP.NET”，但它们都是完全不同的框架。

在Core中，诸如UserManager<TUser>之类的服务是请求范围的，其功能与“每个OWIN上下文”相同。但是，身份在ASP.NET Core中有所不同，因此ApplicationSignInManager之类的内容不再适用。您需要参考文档并实现auth，因为它应该在ASP.NET Core中完成。
