如何在Identity 3.0中获取当前的UserId? User.GetUserId返回null [英] How to get current UserId in Identity 3.0? User.GetUserId returns null

问题描述

我需要获取发出某些请求的用户的ID. 在以前的Identity版本中，我可以这样:

I need to get ID of user that made some request. In previous versions of Identity I could do it like this:

User.Identity.GetUserId();

但是它似乎不再可用.

还有类似的东西:

User.GetUserId();

但是即使User.Identity.IsAuthenticated为true并且User.Identity.Name设置正确，它也始终返回null.

But it always returns null, even if User.Identity.IsAuthenticated in true and User.Identity.Name is set correctly.

我应该怎么做?

我的身份验证逻辑基于

My authenticaton logic is based on [default Visual Studio 2015 template], I hadn't changed much so far in identity, so if you want to check how is it done, you can simply see it on github link I pasted.

推荐答案

在我们的讨论之后，您的用户身份似乎不包含User.GetUserId()使用的正确声明.

Following our discussion, it seems your user identity does not contain the correct claim used by User.GetUserId().

以下是您可以手动设置NameIdentifier声明的方法:

Here is how you can manually set the NameIdentifier claim:

// ClaimsIdentity identity = new ClaimsIdentity...

identity.AddClaim(ClaimTypes.NameIdentifier, user.Id);
