Question

我创建了一个facebook omniauth登录，但身份验证似乎不起作用。

首次登录后，网页更改为Facebook网页，似乎可以正常工作，但重定向由于某种原因返回到我的网页应用登录页面。当我再次点击登录按钮时，我的网络应用程序不会更改网页，而是停留在那里。

但是，我发现我的网址已更改为http://localhost:3000/users/sign_up#= 在我点击注册按钮后，我想知道我的应用程序发生了什么。

<%= link_to "Facebook sign in", user_facebook_omniauth_authorize_path %>是我登录的代码。

我的user.rb是

class User < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  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.email = auth.info.email
    user.password = Devise.friendly_token[0,20]
    # If you are using confirmable and the provider(s) you use validate emails, 
    # uncomment the line below to skip the confirmation emails.
    # user.skip_confirmation!
  end
end
end

routes.rb是

Rails.application.routes.draw do
  devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }
  devise_for :admins, path: 'admins'
  root 'home#index'
  get '/' => "courses#index", as: :user_root
    resources :courses, :lessons
end

我的服务器日志是：
