Integration with PiranhaCMS on ASP.NET Core 2.1

I’ve got a PiranhaCMS site in ASP.NET Core 2.1 that I’m trying to add ecommerce capability to and use Auth0 for customer authentication. I followed (near as I can tell) the QuickStart ( guide.

When I click my Login link, I get the Auth0 login page, I can log in and I get sent back to my app/site, but I get dumped at the blog home page with User.Identity not populated.

My guess is that one of the PiranhaCMS routes is grabbing what should be routed to Auth0 handling. But, I’m not sure how to figure out what’s not working and fix it. I had already disabled the Piranha StartPages module because it wouldn’t let me route “/” to my own controller action.

What I find myself reaching for is something that would let me see how an incoming request got routed through various components to see what’s grabbing it.

So not familiar with PiranhaCMS, but do you have any authentication sample code you’re using and any logs you can share?

Here’s my entire Startup.cs, which, based on the quickstart, is where pretty much everything happens. I’m relatively new to PiranhaCMS myself and am using this as my project to learn ASP.NET Core. I’ve gotten Auth0 working with non-core ASP.NET in the past several times, so I figured I’d delegate that and focus on the other stuff.

As for logging, I think that’s what I’m trying to figure out if I can get it to do more of so I can see what’s going on. This kind of opaque failure is way more frustrating than actual errors. It just appears to work, but doesn’t.

That file has become a bit of a mess as the various tutorials have had me add things. I’ll definitely be re-factoring it once it works.

Do you see any logs in the console?

I had been running in IIS Express, so I switched over to console. This is the relevant bit from the output:

info: Microsoft.AspNetCore.Hosting.Internal.WebHost[1]
      Request starting HTTP/1.1 POST http://localhost:49790/signin-auth0 application/x-www-form-urlencoded 332

      AuthenticationScheme: Identity.External signed in.

      Request starting HTTP/1.1 GET http://localhost:49790/
info: Microsoft.AspNetCore.Authentication.Cookies.CookieAuthenticationHandler[7]
      Identity.Application was not authenticated. Failure message: Ticket expired

From there, it moves on to the CMS path stuff that leads to the blog URL being loaded.
