Question

I can successfully get the contacts from google using OAuth gem in rails. my gmail configuration is :

:google=>{
    :key=>"***",
    :secret=>"***",
    :expose => true, 
    :scope=>"https://www.google.com/m8/feeds/" 
  }

now i want to get contact from yahoo and hot mail. How to get that contact I have given following configuration in my oauth_consumer.rb file

:yahoo=>{
   :client=>:oauth_gem, 
   :expose => true, 
   :allow_login => true, 
   :key=>"**",
   :secret=>"**",
   :scope=>"https://me.yahoo.com"
 }

:hotmail=>{
   :client=>:oauth_gem, 
   :expose => true, 
   :allow_login => true, 
   :key=>"**",
   :secret=>"**"  
 }

Please try to use OmniContacts https://github.com/Diego81/omnicontacts this will help you alot.

1. In your gemfile

   gem "omnicontacts"
   

2. Create config/initializers/omnicontacts.rb

   require "omnicontacts"
   
   Rails.application.middleware.use OmniContacts::Builder do
     importer :gmail, "client_id", "client_secret", {:redirect_path => "/oauth2callback", :ssl_ca_file => "/etc/ssl/certs/curl-ca-bundle.crt"}
     importer :yahoo, "consumer_id", "consumer_secret", {:callback_path => '/callback'}
     importer :hotmail, "client_id", "client_secret"
     importer :facebook, "client_id", "client_secret"
   end
   

3. Create an app to yahoo https://developer.apps.yahoo.com/projects

   This will ask to verify your domain. So, just change your domain of localhost:3000 to local.appname.com:3000 or prefer your live server... (change host in local --- sudo gedit /etc/hosts)

4. in your controller

     @contacts = request.env['omnicontacts.contacts']
     @user = request.env['omnicontacts.user']
     puts "List of contacts of #{user[:name]} obtained from #{params[:importer]}:"
     @contacts.each do |contact|
       puts "Contact found: name => #{contact[:name]}, email => #{contact[:email]}"
     end
