我使用“omniauth-google-oauth2”gem 来设置谷歌登录以及设计登录。还在教程中提到的应用程序根目录中添加了一个 ssl (File => cacert.pem)

在 /config/initializers/omniauth.rb

OmniAuth.config.logger = Rails.logger
Rails.application.config.middleware.use OmniAuth::Builder do  
provider :google_oauth2,"google_clent_id", "google_secret_id",{client_options: {ssl: {ca_file:Rails.root.join("cacert.pem").to_s}}} 
end

在/config/initializers/devise.rb

  config.omniauth :google_oauth2, "google_client_id", "google_secret_id", { name: 'google' }

在routes.rb

devise_for :users, :controllers => { sessions: "sessions", registrations: 'registrations',:omniauth_callbacks => "users/omniauth_callbacks" }
  get 'auth/:provider/callback', to: 'sessions#create'
  get 'auth/failure', to: redirect('/')
  get 'signout', to: 'sessions#destroy', as: 'signout'

在controllers/users/omniauth_callbacks_controller.rb

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
skip_before_action :verify_authenticity_token
  def google_oauth2
      @user = User.from_omniauth(request.env["omniauth.auth"])
      if @user.persisted?
        flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Google"
        sign_in_and_redirect @user, :event => :authentication
      else
        session["devise.google_data"] = request.env["omniauth.auth"]
        redirect_to new_user_registration_url
      end
  end
end

在user.rb

devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :omniauthable,
         :omniauth_providers => [:google_oauth2]
    def self.from_omniauth(auth)
    where(provider: auth.provider, uid: auth.uid).first_or_initialize.tap do |user|
      user.provider = auth.provider
      user.uid = auth.uid
      full_name = auth.info.name.split(" ")
      user.first_name = full_name[0]
      user.last_name = full_name[1]
      user.email = auth.info.email
      user.oauth_token = auth.credentials.token
      user.oauth_expires_at = Time.at(auth.credentials.expires_at)
      user.save!
    end
  end

在sessions_controller.rb

  def create
    user = User.from_omniauth(env["omniauth.auth"])
    session[:user_id] = user.id
    redirect_to root_path
  end

  def destroy
    session[:user_id] = nil
    redirect_to root_path
  end

在我看来（html.erb 文件）

<% if current_user %>
        Signed in as <strong><%= current_user.name %></strong>!
        <%= link_to "Sign out", signout_path, id: "sign_out" %>
      <% else %>
        <%= link_to "Sign in with Google", user_google_oauth2_omniauth_authorize_path, id: "sign_in" %>
      <% end %>

当我点击登录链接时，我重定向到谷歌帐户选择/登录页面。当我使用帐户登录时，页面被重定向到根路径但用户尚未登录。但用户详细信息已记录到数据库用户表中。服务器日志如下所示，

出于安全原因，某些字段更改为星号（****）。用户信息被保存到数据库中的“用户”表中，甚至不需要任何权限。但是为什么用户没有登录呢？我的常规设计登录表单也不起作用。请帮助我理解我在这里做错了什么？提前致谢。

如果有人落后，对我来说问题是我的 gemfile 中缺少 1.9.1。添加它为我解决了这个问题。我花了几个小时检查我的代码是否有错别字，但它一直都是宝石。

宝石“omniauth”，“~> 1.9.1”宝石“omniauth-google-oauth2”

你的代码看起来很不错。但我认为routes.rb你应该添加回调作为附加参数

devise_for :users, controllers: { 
omniauth_callbacks: 'users/omniauth_callbacks' 
}

并绑定或创建用户

def self.from_omniauth(access_token) 
data = access_token.info 
user = User.where(email: data['email']).first 
# Uncomment the section below if you want users to be created if they don't exist 
# unless user 
# user = User.create(name: data['name'], # email: data['email'],
 # password: Devise.friendly_token[0,20] # ) 
# end 
user 
end

请勿在

config/initializers/omniauth.rb:

Rails.application.config.middleware.use 
OmniAuth::Builder do 
provider :google_oauth2, 
  ENV['GOOGLE_CLIENT_ID'],
  ENV['GOOGLE_CLIENT_SECRET'] 
end

定义您的应用程序 ID 和密码 

config/initializers/devise.rb

对于其他权限，您可以使用

Rails.application.config.middleware.use
 OmniAuth::Builder do 
provider :google_oauth2, 
ENV['GOOGLE_CLIENT_ID'], 
ENV['GOOGLE_CLIENT_SECRET'],
 { 
name: 'google', 
scope: 'email, profile, plus.me, http://gdata.youtube.com', 
prompt: 'select_account',
 image_aspect_ratio: 'square', 
image_size: 50
 }

结尾

如果你改变

config.omniauth :google_oauth2, 
ENV["GOOGLE_ID"],
ENV["GOOGLE_SECRET"]

服务器甚至不会启动。然而问题似乎是在一个传递的参数中

config.omniauth :google_oauth2, ENV["GOOGLE_ID"], ENV["GOOGLE_SECRET"],
    { :name => "google", # this is the line that was giving me trouble
    :scope => "email",
    :prompt => "select_account",
    :image_aspect_ratio => "square",
    :image_size => 50 }

我认为您正在改变返回身份验证的方式，即

:google => {:name => "foo", :email => "bar@email.com" }

改变然后不匹配的路线。生成的设计

user_google_oauth2_omniauth_authentication_path

仍然指向

users/auth/google_oauth2/authentication

但是参数中的标记线使oauth期望

users/auth/google/authentication
