我正在使用带有设计的omniauth-twitter gem，并按照railscast了解如何实现它。

一切似乎都正常 - 我可以点击带有 twitter 链接的 sign_up，它会将我重定向到 twitter，我点击“登录”，然后它会将我重定向回来但错误消息“无法从 Twitter 验证你，因为”无效证书”。

我完全不知所措，显而易见的解决方案，比如混淆了我的消费者和我检查过的密钥的位置，它们都很好。

我尝试阅读关于omniauth-devise的几种不同的SO变体，但没有一个有帮助。

以下是相关代码：

 devise_scope :user do
    get 'sign_up', to: 'members#new', controllers: {registrations: "members"}
    get 'partners/sign_up', to: 'content_partners#new', controllers: {registrations: "content_partners"}
  end
  devise_for :users, controllers: {omniauth_callbacks: "omniauth_callbacks"}

从 config/initializers/device 文件：

 require "omniauth-twitter"
   config.omniauth :twitter, 'CONSUMER_KEY', 'CONSUMER_SECRET'

我的宝石文件：

gem "omniauth", "~> 1.1.1"
gem "omniauth-twitter", "~> 0.0.14"

我的控制器：

class OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def all
    user = User.from_omniauth(request.env["omniauth.auth"])
    if user.persisted?
      flash.notice = "Signed in!"
      sign_in_and_redirect user
    else
      session["devise.user_attributes"] = user.attributes
      redirect_to sign_up_path
    end
  end
  alias_method :twitter, :all
end

我的用户模型：

  def self.from_omniauth(auth)
    where(auth.slice(:provider, :uid)).first_or_create do |user|
      user.provider = auth.provider
      user.uid = auth.uid
    end
  end

  def self.new_with_session(params, session)
    if session["devise.user_attributes"]
      new(session["devise.user_attributes"], without_protection: true) do |user|
        user.attributes = params
        user.valid?
      end
    else
      super
    end
  end

我的注册视图文件中的链接：

<%= link_to "or Sign up with Twitter", user_omniauth_authorize_path(:twitter) %>

最后，这是我从记录器中得到的：

(twitter) Callback phase initiated.

谁能帮我解决这个问题？！
