Rack::OAuth2::Client Sample - Authorization Request
require 'rubygems'
require 'rack/oauth2'
client =
:identifier => YOUR_CLIENT_ID,
:redirect_uri => YOUR_REDIRECT_URI, # only required for grant_type = :code
:host => ''
request_type = :token
puts "## request_type = :#{request_type}"
authorization_uri = case request_type
when :code
client.authorization_uri(:scope => :user_about_me)
when :token
client.authorization_uri(:response_type => :token, :scope => :user_about_me)
puts authorization_uri

I don't know how to use and test the client sample. In order to exec the example above, I must have the consts: YOUR_CLIENT_ID,YOUR_CLIENT_SECRET and so on. But where should I register and get the values.


@zhangyuxiu You need a OAuth 2.0 provider, which can be built by rack-oauth2 or any other OAuth2 provider libraries. For example, you can use the Doorkeeper or devise_oauth2_providable.


I must be missing something here; isn't meant to be an OAuth 2.0 provider? How do we use this example client code with that reference implementation using the rack-oauth2 library?
