Getting Data From Authentication

[NachoVazquez]

Please I'm struggling trying to get the data from the authenticated user could you made an tutorial explaining this. Thanks.

could you made an tutorial explaining this

Unfortunately, writing a tutorial needs time. Much more than I can dedicate to this project at this moment.

Have you tried the MVC sample?

I have a similar problem. I created a new project .NET Core > ASP.NET Core Web Application (.NET Core) > Web Application (Change Authentication > Individual User Accounts), I added this nuget package and added a line to Startup.cs:

            app.UseIdentity();

            // Add external authentication middleware below. To configure them please see http://go.microsoft.com/fwlink/?LinkID=532715
            app.UseSteamAuthentication();

            app.UseMvc(
                routes => { routes.MapRoute(name: "default", template: "{controller=Home}/{action=Index}/{id?}"); });
        }

But I get just one claim from steam and that is

http://schemas.microsoft.com/ws/2008/06/identity/claims/authenticationmethod: Steam

[kevinchalet]

@j2ghz you should at least get one claim: ClaimTypes.NameIdentifier (http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier)

To get more claims, create a new app via Steam's portal and register the application key you get in the Steam options:

app.UseSteamAuthentication(options => {
    options.ApplicationKey = "...";
});

I did exactly what the MVC example shows, my problem is that when the OpenId server redirects to my page none controller catch the request and for that reason I can't get the values. Debugging I can see that I already have the values but I can access them from any controller.
Thanks Again and sorry for my English if I made any mistakes.

[NachoVazquez]

This is what I get when the server redirects me, this with a white page. As you can see the address contains the data that I looking for, but I can't find a way to get it.
Also I have to say that i have to alter some constants in the implementation of the client because the server had some other values, for example openid.alias3 instead of openid.ax

I moved my issue so it doesn't get mixed

@NachoVazquez the payload looks fine. If you're getting a blank page, make sure the CallbackPath setting is correct in the OpenID middleware options.

Note: only the claimed identifier will be automatically stored as a claim. To store the other values (e.g the role), you'll have to use the Authenticated event to add a custom claim:

app.UseOpenIdAuthentication(options => {
    // ...

    options.Events = new OpenIdAuthenticationEvents {
        OnAuthenticated = context => {
            string role;
            if (context.Attributes.TryGetValue("role", out role)) {
                context.Identity.AddClaim(new Claim(ClaimTypes.Role, role));
            }

            return Task.FromResult(0);
        }
    };
});
