Client gem for interacting with the CloudFoundry UAA server
For documentation see: https://rubygems.org/gems/cf-uaa-lib
gem install cf-uaa-lib
bundle install
rake install
Create a UAA client that allows users to authenticate with username/password and allow client application to use openid scope to invoke /userinfo endpoint for the user.
uaa create-client decode-token-demo -s decode-token-demo -v \
--authorized_grant_types password,refresh_token \
--scope "openid" \
--authorities uaa.none
Create a user with which to authorize our decode-token-demo client application.
uaa create-user myuser \
--email [email protected] \
--givenName "My" \
--familyName "User" \
--password myuser_secret
Create this Ruby script (script is available at examples/password_grant_and_decode_token.rb):
#!/usr/bin/env ruby
require 'uaa'
url = ENV["UAA_URL"]
client, secret = "decode-token-demo", "decode-token-demo"
username, password = ENV["UAA_USERNAME"], ENV["UAA_PASSWORD"]
def show(title, object)
puts "#{title}: #{object.inspect}"
puts
end
uaa_options = {}
uaa_options[:ssl_ca_file] = ENV["UAA_CA_CERT_FILE"] if ENV["UAA_CA_CERT_FILE"]
show "uaa_options", uaa_options
uaa_info = CF::UAA::Info.new(url, uaa_options)
show "UAA server info", uaa_info.server
token_keys = uaa_info.validation_keys_hash
show "Signing keys for access tokens", token_keys
token_issuer = CF::UAA::TokenIssuer.new(url, client, secret, uaa_options)
show "Login prompts", token_issuer.prompts
token = token_issuer.owner_password_grant(username, password, "openid")
show "User '#{username}' password grant", token
auth_header = "bearer #{token.info["access_token"]}"
show "Auth header for resource server API calls", auth_header
userinfo = uaa_info.whoami(auth_header)
show "User info", userinfo
last_exception = nil
token_keys.each_pair do |keyname, token_key|
begin
token_coder = CF::UAA::TokenCoder.new(uaa_options.merge(pkey: token_key["value"], verify: true))
token_info = token_coder.decode(auth_header)
show "Decoded access token", token_info
last_exception = nil
rescue CF::UAA::Decode => e
last_exception = e
end
end
raise last_exception if last_exceptionTo run the script, setup the env vars for your UAA and run the ruby script:
export UAA_URL=https://192.168.50.6:8443
export UAA_CA_CERT_FILE=/path/to/ca.pem
export UAA_USERNAME=myuser
export UAA_PASSWORD=myuser_secret
ruby examples/password_grant_and_decode_token.rbThe output will look similar to:
uaa_options: {:ssl_ca_file=>"/var/folders/wd/xnncwqp96rj0v1y2nms64mq80000gn/T/tmp.R6wpXYdC/ca.pem"}

Cookie#domain returns dot-less domain name now. Use Cookie#dot_domain if you need "." at the beginning.
