我需要在我的Rails应用程序中添加omniauth Google，Facebook和Twitter的登录，我遵循github上官方文档的omniauth教程。但没有可用的资源，API只应用程序，我是初学者，找不到有用的资源，后端只。请帮助我完成这项任务。我将提供我的代码并以正确的方式指导我。这里我的服务器日志，当我击中API请求从 Postman 在http：//localhost：3000/users/auth/google_oauth2/callback和一些时间得到

控制器

# frozen_string_literal: true
class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  respond_to :json
  skip_before_action :verify_authenticity_token
  skip_before_action :authenticate_request
  protect_from_forgery with: :null_session

  def handle_omniauth(provider)
    @user = User.from_omniauth(request.env["omniauth.auth"])
    
    if @user.persisted?
      render json: { status: 'success', message: "Successfully authenticated via #{provider.capitalize}", user: @user }
    else
      render json: { status: 'error', message: 'Authentication failed', errors: @user.errors.full_messages }, status: :unprocessable_entity
    end
  end
  
  def google_oauth2
    handle_omniauth('Google')
  end

  def twitter
    handle_omniauth('Twitter')
  end

  def facebook
    handle_omniauth('Facebook')
  end
end

型号

class User < ApplicationRecord
  # Devise modules
  devise :database_authenticatable, :registerable, :confirmable,
         :recoverable, :rememberable, :validatable, :trackable,
         :omniauthable, omniauth_providers: [:google_oauth2, :twitter, :facebook]

  # OmniAuth callback method to create or find a user
  def self.from_omniauth(auth)
    user = User.find_by(email: auth.info.email)

    if user
      user.update(provider: auth.provider, uid: auth.uid)
    else
      user = User.create(
        provider: auth.provider,
        uid: auth.uid,
        email: auth.info.email,
        password: Devise.friendly_token[0, 20]
      )
    end

    user
  end
end

我已经在devise.rb和credentials.yml中设置了凭据，我尝试调试，但调试器无法控制。

devise_for :users, controllers: {
    omniauth_callbacks: 'users/omniauth_callbacks'
    registrations: 'users/registrations',
    sessions: 'users/sessions',
    passwords: 'users/passwords'
  }

路由定义得很好，但我仍然无法登录omniauth。

**gems are **
# Authentication
gem 'devise'
gem 'omniauth'
gem 'omniauth-facebook'
gem 'omniauth-google-oauth2'
gem 'omniauth-twitter'
gem 'omniauth-rails_csrf_protection'

我想添加第三方登录，但得到的错误.
