How can AddCustomAction receive data from an outer scope, or service?

[VictorioBerra]

I have the following code:

Audit.Core.Configuration.AddCustomAction(ActionType.OnScopeCreated, scope =>
{
    var httpContext = contextAccessor.HttpContext;
    scope.Event.Environment.CustomFields["NameIdentifierClaim"] = 
        httpContext.User.Claims.Single(x => x.Type == ClaimTypes.NameIdentifier).Value;
});

This has been working great, however, I recently needed to override an OpenIdConnect method:

services.AddAuthentication()
    .AddCookie()
    .AddOpenIdConnect(options =>
    {
        options.Events = new OpenIdConnectEvents()
        {
            OnTokenValidated = (TokenValidatedContext context) =>
            {
                var dbContext = context.HttpContext.RequestServices.GetRequiredService<ApplicationDbContext>();

                var user = dbContext.Users.SingleOrDefault(x => x.NameIdentifierClaim == nameIdentitfierClaimValue);

                if (user is not null)
                {
                    user.NameClaim = nameClaimValue;
                }
                else
                {
                    dbContext.Users.Add(new User());
                }

                // ISSUE!
                // HttpContext.User is not set yet! This happens later in the OpenIdConnect stuff
                // -----------------------------------------------------------------------------------
                dbContext.SaveChanges();

                return Task.CompletedTask;
            }
        };
    });

    return services;
}

The issue here is, HttpContext.User.Claims is empty in the Audit.Core.Configuration.AddCustomAction, which is envoked when calling dbContext.SaveChanges() in the OnTokenValidated event for AddOpenIdConnect().

Is there some way to propagate that value, so I can look for it, and receive it in the AddCustomAction scope? Like an outer scope, that it could detect?

What I ended up doing was using a scoped service with a property I can set, and later access.

// Startup.cs
services.AddScoped<ICustomRequestContainer, CustomRequestContainer>();

// OpenIdConnectExtensions.cs
// ... somewhere in OnTokenValidated
var customRequestontainer = context.HttpContext.RequestServices.GetRequiredService<ICustomRequestContainer>();
customRequestontainer.NameIdentifierClaim = nameIdentitfierClaimValue;
// ...
dbContext.SaveChanges();

// AuditExtensions.cs
Audit.Core.Configuration.AddCustomAction(ActionType.OnScopeCreated, scope =>
{
    var httpContext = contextAccessor.HttpContext;

    var customRequestContainer = httpContext.RequestServices.GetRequiredService<ICustomRequestContainer>();
    var nameIdentifierFromRequest = customRequestContainer.NameIdentifierClaim;

    if (nameIdentifierFromRequest is not null)
    {
        scope.Event.Environment.CustomFields["NameIdentifierClaim"] = nameIdentifierFromRequest;
    } 
    else
    {
        scope.Event.Environment.CustomFields["NameIdentifierClaim"] = 
            httpContext.User.Claims.Single(x => x.Type == ClaimTypes.NameIdentifier).Value;
    }
});
