Alias not working with mezzio-authentication-oauth2

Questions Mezzio

Hi,

I am trying to get the oAuth2 working with a mezzio application using mezzio-authentication-oauth2.
I can’t seem to get past an error:
Too few arguments to function Mezzio\Authentication\AuthenticationMiddleware::__construct(), 0 passed

As far as I understand, it shouldn’t need a value passed as I am setting an alias as described in the docs here:
https://docs.mezzio.dev/mezzio-authentication-oauth2/v1/usage/#authenticate-a-middleware

Is there a bug here? It sounds very similar to what weierophinney was experiencing here:

Perhaps I should be using a different library for oAuth2?
Any help is appreciated.

It seems that the factory for this middleware is not used / registered. Please check your configuration that the config provider of mezzio-authentication (Mezzio\Authentication\ConfigProvider::class) was added.

That interesting @froschdesign, thanks for that. I would not have worked that out without your help.

Getting in “AuthenticationInterface service is missing” in /vendor/mezzio/mezzio-authentication/src/AuthenticationMiddlewareFactory.php:33

Any idea what is causing that?

Hi,
Looks like I need 2 of them in the config:
\Mezzio\Authentication\OAuth2\ConfigProvider::class,
\Mezzio\Authentication\ConfigProvider::class,

Unfortunately I am off an application generated by OpenApiTool Generator instead of the mezzio skeleton, which provides a lot of features I would take for granted.

It is looking for the public.key file now, so I should be able to work with that.

Thanks again @froschdesign
