'openid-connect client in ruby with example code

I want to read data from an API which requires authorization with openid-connect. My client should be written in ruby, so I can use it in a task to import data into my rails app.

I am given a configuration under theapi/.well-known/openid-configuration along with a client_id and a client_secret.

Having never worked with openid before I did some research an found the following gems that might help to obtain an auth token:

Both gems lack of any documentation or examples to get started, in fact I am not even sure if they are useful for my case.

Also there is a similar SO-post, but it's five years old with zero answers: Ruby Openid connect library with client consumption example

Could anybody help me out with a simple example on how to authorize against openid_connect in ruby, possibly using one of the mentioned gems?

I had the same issue and found a nice tutorial to solve this challenge FusionAuth

You require these 2 gems in your gemfile: gem 'jwt' and gem 'oauth2'

You will also be able to initialize the OAuth Client while replacing actual values of your Identity Server:

@oauth_client = OAuth2::Client.new(Rails.configuration.x.oauth.client_id,
                                   Rails.configuration.x.oauth.client_secret,
                                   authorize_url: '/oauth2/authorize',
                                   site: Rails.configuration.x.oauth.idp_url,
                                   token_url: '/oauth2/token',
                                   redirect_uri: Rails.configuration.x.oauth.redirect_uri)

With the OAuthClient initalised you can be able to perform your desired OAuth Flow.

For Authorization with password_credentials you can use:

response = @oauth_client.client_credentials.get_token
token = response.token

You can find more Authorization Type References here: OAuth2 Docs

These two resources should enable you to complete your integration with any IdentityServer. Hope these resources stay updated.
