Ahh okay, the NeoPass spec says to pass the `client_id` and
`client_secret` as POST form data when exchanging the code for the
access token, but the default behavior of our client is to pass it as
an `Authorization` header instead.
In this change, we set an option to change that behavior, and also add
a lot of comments about this and the other options!
Wowie, it's starting to happen! :3
When you run this in production, though, you get back the auth failure
message, and the OmniAuth logs say the server returned the following:
> invalid_client: Client authentication failed (e.g., unknown client,
> no client authentication included, or unsupported authentication
> method). The OAuth 2.0 Client supports client authentication method
> 'client_secret_post', but method 'client_secret_basic' was requested.
> You must configure the OAuth 2.0 client's
> 'token_endpoint_auth_method' value to accept 'client_secret_basic'.
I'll add a fix for this in the next commit, with some explanations as
to why!
Right, I didn't totally connect the dots that there's some OpenID
features in the mix here for how we expect to identify the user once
they authenticate. It requires looking up the provider's public key,
and validating the JWT they sent us. This gem does all that for us!
I don't actually know what a real NeoPass `id_token` looks like yet?
But I'll fill in some placeholder stuff for now, and use that for
initializing the account!
In this change, we wire up a new NeoPass OAuth2 strategy for OmniAuth,
and hook up the "Log in with NeoPass" button to use it!
The authentication currently fails with `invalid_credentials`, and
shows the `owo` response we hardcoded into the NeoPass server's token
response. We need to finally follow up on the little `TODO` written in
there!
This is setting us up for NeoPass, but first we're just gonna try stuff
with the "developer" strategy that's built in for testing, rather than
using the NeoPass dev server!
A lot of rough edges here (e.g. no styles on the flash messages), but it's working and that's good!!
I tested this by temporarily switching to the production database and logging in as matchu!
Still missing a lot of big features too, like registration, password resets, settings page, etc.
This removes login/logout/session logic for integrating with OpenNeo ID, replacing them with stubs that just redirect to `/?TODO` when you click login, and helpers that act as if you're not logged in.
This gives us a clean slate to plug in new Devise logic to integrate with the `openneo_id` database directly!
I guess the APIs changed here, but these were placeholder settings we weren't actually using anyway (cuz we use the OpenNeo ID integration), so I just commented them out and it seems fine for now!
