OmniAuth::MojeID
MojeID authentication strategy.
OmniAuth::MojeID is an extension to OmniAuth::OpenID with some useful defaults and added attributes.
Installation
gem install omniauth-mojeid
Configuration
Rails 3 + Devise + OmniAuthable
Inside devise.rb, add a simple line:
config.omniauth :mojeidThis will prompt the user for the default attributes. If you want to configure which attributes to obtain from the user, specify them in the required and optional fields.
config.omniauth :mojeid, :required => [:name, :email], :optional => [:city]See full list of profile attributes.
Stand-Alone Example
Use the strategy as a middleware in your application:
require 'omniauth-mojeid'
use Rack::Session::Cookie
use OmniAuth::Strategies::MojeIDOmniAuth Builder
If MojeID is one of several authentication strategies, use the OmniAuth Builder:
require 'omniauth-mojeid'
use OmniAuth::Builder do
provider :mojeid
endBy default, the omniauth information during the response handling is stored in ruby-openid's Memory Store. To change this, override the store option:
require 'omniauth-openid'
require 'openid/store/filesystem'
use OmniAuth::Builder do
provider :mojeid, :store => OpenID::Store::Filesystem.new('/tmp')
endAuthentization Verification
Create an xml file and make it available at YOUR_URL/xrds.xml. The file should contain this text (don't forget to replace YOUR_URL):
<?xml version="1.0" encoding="UTF-8"?>
<xrds:XRDS xmlns:xrds="xri://$xrds" xmlns="xri://$xrd*($v*2.0)">
<XRD>
<Service>
<Type>http://specs.openid.net/auth/2.0/return_to</Type>
<URI>***YOUR_URL***/auth/mojeid/callback</URI>
</Service>
</XRD>
</xrds:XRDS>Usage
Simply point users to /auth/mojeid which will redirect them to MojeID.cz website to prompt them for their profile information.
In the response callback at /auth/mojeid/callback, the attributes will become available in the ["omniauth.auth"]["info"] hash. So, to print out user's email, use ["omniauth.auth"]["info"][:email].
To learn about the internals please read the specification (in Czech).
Profile attributes
By default, mojeid asks user for the following profile attributes:
:required => [:email, :name, :first_name, :last_name]
:optional => [:nickname, :street, :city, :postal_code, :country]If you want to customize the information, use the attributes listed in the table below.
You can also use the Simple Reg name (as a string) to name the attributes. (Though in my experience the mapping doesn't seem to be working well.)
:required => ['email', 'fullname', :first_name, :last_name, 'dob']Note that the user can decide if they share the information with you, so even if you request certain fields, they may be empty (nil).
Also note that you may not request the same attribute both in the required and optional fields otherwise an error will be raised.
