Question

我正在尝试使用Rails 5.2.1应用和gem'omniauth-google-oauth2'设置google登录。我期望authenticate_user将为我创建用户实例，但它没有考虑我在Users :: OmniauthCallbacksController中编写的任何代码。我可以看到google登录页面，单击“允许”后成功调用已配置的网址。只是current_user尚未设置。我将不胜感激任何调试指导或文章指导我。

我尝试将binding.pry放在warden-1.2.7 / lib / warden / proxy.rb中的wardens def authenticate！（* args）中，但似乎只有一种策略：{：user => []} 。谷歌oauth也应该作为一种策略吗？

routes.rb：

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

gemfile：

gem 'rails', '~> 5.2.1'
gem 'devise'
gem 'omniauth-google-oauth2'

devise.rb： MISTAKES是我正在创建的应用的名称

require 'omniauth-google-oauth2'
  GOOGLE_OAUTH_MISTAKES_CONFIGURATION = {
    scope: "contacts.readonly,userinfo.email",
    redirect_uri: 'http://localhost:3000/home/index'
  }

  config.omniauth :google_oauth2, ENV['GOOGLE_CLIENT_ID'], ENV['GOOGLE_CLIENT_SECRET'], GOOGLE_OAUTH_MISTAKES_CONFIGURATION

OmniauthCallbacksController

def google_oauth2
      binding.pry # Control does not reach here
      # You need to implement the method below in your model (e.g. app/models/user.rb)
      @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'].except(:extra) # Removing extra as it can overflow some session stores
        redirect_to new_user_registration_url, alert: @user.errors.full_messages.join("\n")
      end
  end

user.rb：

  devise :omniauthable, omniauth_providers: [:google_oauth2]
  .
  .
  .
  def self.from_omniauth(access_token)
    binding.pry # Control does not reach here
    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

我希望在Google重定向到我配置的redirect_uri（它是）之后，before_action：authenticate_user！将为我提供current_user的实例，但它只是抛出401次很多，直到由于太多401而退出浏览器

如何解决为什么在authenticate_user
