Asp.Net Core 2中AuthenticationResponseGrant的替代方案

Question

AspNet Core 2中是否有以下代码的替代方法？

<div class="container">
  <div>Element</div>
  <div class="top">Top Element</div>
  <div>Element</div>
  <div class="bottom">Bottom Element</div>
  <div>Element</div>
</div>

我想更改cookie中的一些User Principal值，我不打算在数据库中保留这些值。是否可以在Asp Net Core版本2中使用上述代码？我查看了var identity = HttpContext.User.Identity as ClaimsIdentity; identity.RemoveClaim(Identity.FindFirst("AnnounceCount")); identity.AddClaim(new Claim("AnnounceCount", "Updated Value")); var authenticationManager = System.Web.HttpContext.Current.GetOwinContext().Authentication; authenticationManager.AuthenticationResponseGrant = new AuthenticationResponseGrant(new ClaimsPrincipal(identity), new AuthenticationProperties() { IsPersistent = true }); ，OnValidatePrincipal实现，但这两个都不符合我的需求。我在这里错过了什么吗？
