Question

我正在跟随Railscast http://railscasts.com/episodes/235-devise-and-omniauth-revised?view=comments关于将omniauth实现到devise中，特别是添加了Twitter signin。当我添加链接以登录Twitter到我的应用程序时，我收到此错误访问主页

  <li><%= link_to "Sign In With Twitter", user_omniauth_authorize_path(:provider) %></li>

No route matches {:controller=>"omniauth_callbacks", :action=>"passthru", :provider=>:provider}

如果我做rake路由（见下文），它表明我有'user_omniauth_callback'路由，但它没有指定请求类型（GET，POST）等，我不确定是否重要。

我在SO上搜索了这个错误，并且有一个人因为在routes.rb中不包含以下代码而导致了类似的问题，但我已将其包括在内。

devise_for :users, path_names: {sign_in: "login", sign_out: "logout"},
                   controllers: {omniauth_callbacks: "omniauth_callbacks"}

错误出现在他加入omniauth控制器的剧集部分之前;我添加它只是为了确定，但我仍然得到同样的错误：

class OmniauthCallbacksController < Devise::OmniauthCallbacksController

    def all
        request.env["omniauth.auth"]

    end

    alias_method :twitter, :all
end

我不确定我还能看到什么。在设计初始化程序中，我为Twitter设置了配置

config.omniauth :twitter, ENV["TWITTER_KEY"], ENV["TWITTER_SECRET"]

这是我的用户模型

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


  attr_accessible :email, :password, :password_confirmation, :remember_me, :name, :image, :provider, :uid

  validates_uniqueness_of :name, :email, :case_sensitive => false
end

您能就我可能采取的措施提出任何建议来解决这个问题吗？

Answer 1

错误在于我传递的是：提供者而不是：twitter作为链接中的参数。

不正确的

<%= link_to "Sign In With Twitter", user_omniauth_authorize_path(:provider) %>

正确：

 <%= link_to "Sign In With Twitter", user_omniauth_authorize_path(:twitter) %>

rake routes表示路由存在但错误消息另有说明
