How can I authenticate users in a Rails app with oauth and twitter 1.0.0 gems?

Question

Jnunemaker just updated his twitter (https://github.com/jnunemaker/twitter) and removed the Twitter :: Oauth class. My code is not very similar to its example, so I am having problems updating it. Here is what my code used to look with the twitter 0.9 gem:

UsersController

def oauth
  consumer = Twitter::OAuth.new('mykey','mysecret')
  request_token = consumer.request_token  
  session[:request_token] = request_token.token  
  session[:request_token_secret] = request_token.secret
  redirect_to 'http://api.twitter.com/oauth/authorize?oauth_token='+request_token.token
end

def callback
  consumer = Twitter::OAuth.new('mykey','mysecret')
  atoken, asecret = oauth.authorize_from_request(session[:request_token], session[:request_token_secret], params[:oauth_verifier])  
  consumer.authorize_from_access(atoken,asecret)
  user = Twitter::Base.new(consumer).verify_credentials

  #and then I create a new user in my application, with attributes such as the user follower count, etc
end

Here is an example of what I was trying to do to change this code:

UsersController

def oauth
  consumer = OAuth::Consumer.new("mykey", "mysecret", :site => "siteurl")
  request_token = consumer.get_request_token
  session[:request_token] = request_token.token  
  session[:request_token_secret] = request_token.secret
  redirect_to 'http://api.twitter.com/oauth/authorize?oauth_token='+request_token.token
end

def callback
  consumer = OAuth::Consumer.new("mykey", "mysecret", :site => "siteurl")
  request_token = session[:request_token]
  atoken = OAuth::RequestToken.new(consumer, request_token.token, request_token.secret).get_access_token(:oauth_verifier => params[:oauth_verifier])
  consumer.authorize_from_access(atoken)
  user = Twitter::Client.new(consumer).verify_credentials

Gemfile

...
gem 'oauth'

I am sure there are several errors in my callback method, but one thing that is strange is that my oauth method works fine when I run locally, but gives me the "502 Bad Gateway" error when I try from my live version (deployed with heroku).

, , Omniauth Twitter. Omniauth .

Twitter, Omniauth:

token = omniauth['credentials']['token'], 
secret = omniauth['credentials']['secret']

Twitter, Twitter

Twitter.oauth_token = token
Twitter.oauth_token_secret = secret

Twitter.home_timeline.first.text

( gem customer_key user_key_secret, ...)

You were close in your example. The correct code for your controller action would be something like this:

  def new
    consumer = OAuth::Consumer.new(YOUR_CONSUMER_TOKEN, YOUR_CONSUMER_SECRET, site: 'https://api.twitter.com', request_endpoint: 'https://api.twitter.com', authorize_path: '/oauth/authenticate')

    unless params[:oauth_token]
      request_token = consumer.get_request_token({ oauth_callback: request.original_url })
      session[:request_token] = { token: request_token.token, secret: request_token.secret}
      redirect_to request_token.authorize_url(force_login: 'true')
    else
      request_token = OAuth::RequestToken.from_hash(consumer, oauth_token: session[:request_token]["token"], oauth_token_secret: session[:request_token]["secret"])
      access_token = request_token.get_access_token(oauth_verifier: params[:oauth_verifier])
      session[:request_token] = nil

      @client = Twitter::REST::Client.new do |config|
        config.consumer_key        = YOUR_CONSUMER_TOKEN
        config.consumer_secret     = YOUR_CONSUMER_SECRET
        config.access_token        = access_token.token
        config.access_token_secret = access_token.secret
      end
    end
  end
