我现在看几天来解决这个问题。 使用user.identity.name或user.identity.username登录后我得到了正确的值。
但是，当我想知道用户ID时，我得到一个null。
一切正常我可以登录我可以通过user.identity.name看到我的用户名 但是当我想看到我的用户ID然后我得到一个空的，有人知道这个问题是什么？

答案 0 :(得分：3)
我遇到了与OAuth相同的问题。 RequestContext.Principal.Identity.GetUserName()返回了用户名，但RequestContext.Principal.Identity.GetUserId()返回了null。
原来我必须在用户登录时设置NameIdentifier声明。对我而言，这是GrantResourceOwnerCredentials
OAuthAuthorizationServerProvider方法
identity.AddClaim(new Claim(ClaimTypes.NameIdentifier, user.Id));
添加此声明后，GetUserId开始返回用户的ID。
