I want to make request through curl or other stuff (Net::HTTP.get). How can I set request.env['omniauth.auth'] when I make request? What is request.env in general? 
For example, take a look at https://github.com/intridea/omniauth#integrating-omniauth-into-your-application
class SessionsController < ApplicationController
  def create
    @user = User.find_or_create_from_auth_hash(auth_hash)
    self.current_user = @user
    redirect_to '/'
  end
  protected
  def auth_hash
    request.env['omniauth.auth']
  end
end
I don't know how to set request.env['omniauth.auth'] when I do curl
