Custom session property with .NET Core project #2333

Hi,

I am adding custom properties to a session with the process outlined on this page: <a class="postlink" href="https://gist.github.com/hikalkan/67469e05475c2d18cb88">https://gist.github.com/hikalkan/67469e05475c2d18cb88</a>, this worked fine on an .NET MVC 5.x project, however implementing it in the same fashion on a .NET Core project causes a null reference error with HttpContext when adding a new cookie to the authentication manager.

Is there another way of achieving custom session properties with the new .NET Core project? I need to be able to add them in the overridden TryAuthenticateAsync method in a custom authentication layer.

Thanks

    Hi,

    You can add custom claims before this line: <a class="postlink" href="https://github.com/aspnetzero/aspnet-zero-core/blob/dev/aspnet-core/src/MyCompanyName.AbpZeroTemplate.Web.Mvc/Controllers/AccountController.cs#L155">https://github.com/aspnetzero/aspnet-ze ... er.cs#L155</a> like shown below:

    loginResult.Identity.AddClaim(...);

    Alternatively, you can override CreateIdentityAsync method in UserManager, like this:

    public override async Task<ClaimsIdentity> CreateIdentityAsync(User user, string authenticationType)
{
    var identity = await base.CreateIdentityAsync(user, authenticationType);
    identity.AddClaim(...);
    return identity;
}

    Hi,

    Thanks for the reply

    Apologies I should have mentioned it was the Angular 2 and .NET Core project, I don't have that controller in the server project.

    This is what I was using in another project that was .NET MVC 5.x, if possible I'd like for it to be achieved in a similar fashion:

    public string UserToken
        {
            get
            {
                ClaimsPrincipal claimsPrincipal = Thread.CurrentPrincipal as ClaimsPrincipal;
                if (claimsPrincipal == null)
                {
                    return null;
                }

                ClaimsIdentity identity = claimsPrincipal.Identities.First();
                if (identity == null)
                {
                    return null;
                }

                Claim tokenClaim = identity.Claims.FirstOrDefault(c => c.Type == "User_Token");
                if (tokenClaim == null || string.IsNullOrEmpty(tokenClaim.Value))
                {
                    return null;
                }

                return tokenClaim.Value;
            }
            set
            {
                ClaimsPrincipal claimsPrincipal = Thread.CurrentPrincipal as ClaimsPrincipal;
                var identity = claimsPrincipal.Identities.First();

                Claim tokenClaim = identity.Claims.FirstOrDefault(c => c.Type == "User_Token");

                if (tokenClaim != null)
                {
                    identity.RemoveClaim(tokenClaim);
                }

                identity.AddClaim(new Claim("User_Token", value));
                var authenticationManager = HttpContext.Current.GetOwinContext().Authentication;
                authenticationManager.SignOut(DefaultAuthenticationTypes.ApplicationCookie);
                authenticationManager.SignIn(new AuthenticationProperties { IsPersistent = true }, identity);
            }
        }

    Thanks

    Hi,

    If you are using angular2 template, then you can do it in TokenAuthController just before this line <a class="postlink" href="https://github.com/aspnetzero/aspnet-zero-core/blob/dev/aspnet-core/src/MyCompanyName.AbpZeroTemplate.Web.Core/Controllers/TokenAuthController.cs#L136">https://github.com/aspnetzero/aspnet-ze ... er.cs#L136</a>.
