如何在 ASP.NET Core 中获取当前登录的用户 ID?

问题描述：

我之前使用 User.Identity.GetUserId() 使用 MVC5 完成了此操作，但这在这里似乎不起作用.User.Identity 没有 GetUserId() 方法.

I've done this before with MVC5 using User.Identity.GetUserId() but that doesn't seem to work here. The User.Identity doesn't have the GetUserId() method.

我正在使用 Microsoft.AspNet.Identity.

答

我包括使用 System.Security.Claims 并且我可以访问 GetUserId() 扩展方法

I included using System.Security.Claims and I could access the GetUserId() extension method

注意:我已经使用了 Microsoft.AspNet.Identity 但无法获得扩展方法.所以我想这两者必须相互结合使用

NB: I had the using Microsoft.AspNet.Identity already but couldn't get the extension method. So I guess both of them have to be used in conjunction with one another

using Microsoft.AspNet.Identity;
using System.Security.Claims;

编辑:这个答案现在已经过时了.查看 Soren 或 Adrien 的答案，了解在 CORE 1.0 中实现这一目标的过时方法

EDIT: This answer is now outdated. Look at Soren's or Adrien's answer for a dated way of achieving this in CORE 1.0
