How to get current UserId in Identity 3.0? User.GetUserId returns null
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();
But it seems it isn't available anymore.
There is also something like:
User.GetUserId();
But it always returns null, even if User.Identity.IsAuthenticated in true and User.Identity.Name is set correctly.
What should I use to do it?
EDIT: 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.
Following our discussion, it seems your user identity does not contain the correct claim used by User.GetUserId().
Here is how you can manually set the NameIdentifier claim:
// ClaimsIdentity identity = new ClaimsIdentity...
identity.AddClaim(ClaimTypes.NameIdentifier, user.Id);
I think there was a built in extension method for that in previous versions but they removed it. you can implement your own to replace it:
using System;
using System.Security.Claims;
using Microsoft.AspNet.Identity;
namespace cloudscribe.Core.Identity
{
public static class ClaimsPrincipalExtensions
{
public static string GetUserId(this ClaimsPrincipal principal)
{
if (principal == null)
{
throw new ArgumentNullException(nameof(principal));
}
var claim = principal.FindFirst(ClaimTypes.NameIdentifier);
return claim != null ? claim.Value : null;
}
}
}
ClaimType.NameIdentifier should map to userid
@Joe Audette
it turns out it has been move to other place.
User.GetUserId => UserManager.GetUserId(User)
User.GetUserName => UserManager.GetUserName(User)
User.IsSignedIn => SignInManager.IsSignedIn(User)
