我安装了设计身份验证，没有问题。现在我正在尝试添加一个使用Omniauth-facebook登录Facebook的选项。
我按照本指南中的说明进行操作，但是在访问 urllocalhost:3000/auth/facebook时，我收到有关缺少"直通"文档的错误。
这是我得到的第一个错误：
Unknown action
The action 'passthru' could not be found for RegistrationsController
我尝试了创可贴修复，只需向我的控制器添加一个空的"直通"操作：
def passthru
end
这解决了这个错误，但我得到了一个不同的回报：
Template is missing
Missing template registrations/passthru, devise/registrations/passthru, devise/passthru, application/passthru with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :raw, :ruby, :jbuilder, :coffee]}. Searched in: * "/home/user/project/app/views" * "/home/user/.rvm/gems/ruby-2.0.0-p648@railstutorial_rails_4_0/gems/devise-3.5.2/app/views"
我尝试在规定的文件夹中创建"passthru.html.erb"，但该错误仍然存在。无论如何，我认为这些错误象征着一个更深层次的问题。
还有其他人遇到过这个问题吗？我能找到的只是这个SO问题，但没有一个答案是有帮助的。
到目前为止我的代码：
宝石文件
gem 'devise'
gem 'omniauth-facebook'
gem 'omniauth'
路线.rb
devise_for ：成员、控制器：{ 注册："注册"，omniauth_callbacks: 'registrations' }
会员.rb
devise :database_authenticatable, :registerable,
:omniauthable, :omniauth_providers => [:facebook]
def self.from_omniauth(auth)
where(provider: auth.provider, uid: auth.uid).first_or_create do |member|
member.email = auth.info.email
member.password = Devise.friendly_token[0,20]
member.title = auth.info.name
end
end
registrations_controller.rb
def facebook
@member = Member.from_omniauth(request.env["omniauth.auth"])
if @member.persisted?
sign_in_and_redirect @member, :event => :authentication
set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
else
session["devise.facebook_data"] = request.env["omniauth.auth"]
redirect_to new_member_registration_url
end
end
def failure
redirect_to root_path
end
def passthru
end
Initializers/devise.rb
config.omniauth :facebook, "<app_id>", "<app_secret>"
试试这个：
更新宝石文件：
gem 'omniauth-facebook'
gem 'omniauth'
Goto rails_apps/yourapp/config/initializers/devise.rb
Devise.setup do |config|
config.omniauth :facebook, "KEY", "SECRET"
end
更新用户模型
class User < ActiveRecord::Base
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable,
:omniauthable, :omniauth_providers => [:facebook]
def self.from_omniauth(auth)
where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
user.provider = auth.provider
user.uid = auth.uid
user.email = auth.info.email
user.password = Devise.friendly_token[0,20]
end
end
end
转到 ： rails_apps/yourapp/config/routes.rb
Rails.application.routes.draw do
devise_for :users
resources :users
end
在视图中编辑
<%= link_to "Sign in with Facebook", "/auth/facebook", id: "sign_in" %>
Passthru 是来自 omniauth 的遗物，更新您的 Gems of Design Omniauth 等等。 有一个控制器叫做omiauth_callback这是;P噪音的控制器。(可以帮助您追踪问题的根源)
如果您在控制器中创建这样的方法：
def passthru
end
你必须创建一个视图(甚至是空的)，或者重定向：从ajax技术中获得灵感来绕过html渲染。 希望它能送你解决问题。
也试试这些路线： ``` user_omniauth_authorize/users/auth/:p rovider(.：format) sessions#passthru {:p rovider=>/facebook|twitter|google/}
user_omniauth_callback/users/auth/：action/callback(.：format) sessions#(？-mix：facebook|twitter|google) ```
您可以为Omniauth callback创建另一个控制器
class OmniauthCallbacksController < Devise::OmniauthCallbacksController
def facebook
@user = User.from_omniauth(request.env['omniauth.auth'])
if @user.persisted?
sign_in_and_redirect @user, :event => :authentication
set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
else
session["devise.facebook_data"] = request.env["omniauth.auth"]
redirect_to new_user_registration_url
end
end
def after_sign_in_path_for(resource)
super resource
end
end
您需要将路线重置为
devise_for :members, :controllers => {:registrations => "members/registrations", :omniauth_callbacks => 'omniauth_callbacks'}
我记得你不需要在你的member.rb中使用:omniauth_providers => [:facebook]
现在，您可以在sign_up page中添加一个按钮，或者改为在devise/shared/_links.html.erb中包含以下代码，因为它也将在您的sign_in表单中可用。
<%- if devise_mapping.omniauthable? %>
<%- resource_class.omniauth_providers.each do |provider| %>
<%= link_to "Sign up with #{provider.to_s.titleize}", omniauth_authorize_path(resource_name, provider), class: "btn btn-default navbar-btn" %><br />
<% end -%>
<% end -%>
您还需要在初始值设定项中配置 Devise
在你的/config/initializers/devise.rb
config.omniauth :facebook, "App ID", "App Secret", scope: 'email', info_fields: 'email,name'
请通过这个最简单的教程Sing_up与脸书链接
试试这个......
config/initializers/devise.rb
config.omniauth :facebook, ENV["FACEBOOK_KEY"], ENV["FACEBOOK_SECRET"], { :scope => 'email, offline_access'}
config/routes.rb
devise_for :members, controllers: { registrations: 'registrations', omniauth_callbacks: "omniauth_callbacks" }
app/models/member.rb
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable, :omniauthable
def self.from_omniauth(auth)
where(provider: auth.provider, uid: auth.uid).first_or_create do |member|
member.email = auth.info.email
member.password = Devise.friendly_token[0,20]
member.title = auth.info.name
end
end
app/controllers/omniauth_callbacks_controller.rb
skip_before_filter :authenticate_user!
def facebook
p env["omniauth.auth"]
user = User.from_omniauth(env["omniauth.auth"])
if user.persisted?
flash[:notice] = "You are in..!!!"
sign_in_and_redirect(user)
else
session["devise.user_attributes"] = user.attributes
redirect_to new_user_registration_url
end
end
def failure
#handle you logic here..
#and delegate to super.
super
end
希望这对你有用。
我认为问题总是出在按钮或锚点上，所以使用这个
<%= link_to user_facebook_omniauth_authorize_path, method: :post do %>
login with facebook
<% end %>
