身份验证失败：Devise + OmniAuth + Twitter

我正进入（状态(twitter) Authentication failure! invalid_credentials: OAuth::Unauthorized, 401 Unauthorized成功登录 Twitter 并且页面重定向到登录页面后出现错误

这是应用程序配置

路线.rb

devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }

设计.rb

config.omniauth :twitter, "KEY", "SECRET"

omn​​iauth_callbacks_controller.rb

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController  
  def twitter
    auth = env["omniauth.auth"]
    Rails.logger.info("auth is **************** #{auth.to_yaml}")
    @user = user = User.find_by_provider_and_uid(auth["provider"], auth["uid"]) || User.new
    if @user.persisted?
      flash[:notice] = I18n.t "devise.omniauth_callbacks.success"
      sign_in_and_redirect @user, :event => :authentication
    else
      session["devise.twitter_uid"] = auth["uid"]
      redirect_to new_user_registration_url
    end
  end
end

user.rb

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, :omniauthable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me, :provider, :uid
  # attr_accessible :title, :body
end

索引.html.erb

<h3>Home</h3>

<%if user_signed_in? %>
  <div><%="Welcome #{current_user.email}"%></div>

<div><%=link_to "Logout", destroy_user_session_path, method: :delete%></div>

<%else%>

dev.twitter.com 中的回调 URL早些时候是http://127.0.0.1:3000. From Devise、Omniauth 和 Twitter我把它改为http://127.0.0.1:3000/auth/twitter/callback但仍然出现错误

有人可以帮忙解决这个问题吗？

谢谢， 阿米特·帕特尔

我发现了这个问题。我已经在两个中配置了提供程序devise.rb and omniauth.rb。我只是删除了omniauth.rb，它就开始工作了。
