Omniauth OAuth2 made a breaking change to callback_url

[jtokoph]

This merged commit removed the callback_url method override: omniauth/omniauth-oauth2#70

It now defers to the base strategy callback_url which appends the current query string to the redirect_uri that is passed to the token request. This breaks the omniauth-twitch gem since twitch expects a redirect_uri that exactly matches the config

Two possible fixes:

1. Pin the omniauth-oauth2 dependency to 1.3.1 or less:

   spec.add_runtime_dependency 'omniauth-oauth2', ['>= 1.1', '<= 1.3.1']

2. Override the callback_url method in the strategy:

   def callback_url
     full_host + script_name + callback_path
   end

Thanks for the fix, works like a charm. Saved my project for school! ʘ ͜ʖ ʘ
