ruby-on-rails - Rails API Omniauth

Question

我正在尝试使用 NuxtJS 框架通过 Devise in Rails API 实现 Omniauth。

我使用 Omniauth 方法进行了身份验证模块连接和用户帐户创建，但我想了解如何在登录/注册后重定向用户，我是 Rails 开发人员和 NuxtJS 初学者。

后端

用户模型oauth注册方法:

def self.from_facebook(auth)
 where(uid: auth.uid, provider: auth.provider).first_or_create do |user|
  user.email = auth.info.email
  user.first_name = auth.info.first_name
  user.last_name = auth.info.last_name
  user.password = Devise.friendly_token[0, 20]
  user.provider = auth.provider
  user.uid = auth.uid
  Client.create(user: user)
 end
end

注册 Controller :

# frozen_string_literal: true

module Overrides
class RegistrationsController < DeviseTokenAuth::ApplicationController
before_action :set_user_by_token, only: [:destroy, :update]
before_action :validate_sign_up_params, only: :create
before_action :validate_account_update_params, only: :update
skip_after_action :update_auth_header, only: [:create, :destroy]

def create
  build_resource

  unless @resource.present?
    raise DeviseTokenAuth::Errors::NoResourceDefinedError,
          "#{self.class.name} #build_resource does not define @resource,"\
          ' execution stopped.'
  end

  # give redirect value from params priority
  @redirect_url = params.fetch(
    :confirm_success_url,
    DeviseTokenAuth.default_confirm_success_url
  )

  # success redirect url is required
  if confirmable_enabled? && !@redirect_url
    return render_create_error_missing_confirm_success_url
  end

  # if whitelist is set, validate redirect_url against whitelist
  return render_create_error_redirect_url_not_allowed if blacklisted_redirect_url?

  # override email confirmation, must be sent manually from ctrl
  resource_class.set_callback('create', :after, :send_on_create_confirmation_instructions)
  resource_class.skip_callback('create', :after, :send_on_create_confirmation_instructions)

  if @resource.respond_to? :skip_confirmation_notification!
    # Fix duplicate e-mails by disabling Devise confirmation e-mail
    @resource.skip_confirmation_notification!
  end

  if @resource.save
    if params[:farmer]
      Farmer.create(
        user: @resource
      )
    else
      Client.create(
        user: @resource
      )
    end

    yield @resource if block_given?

    unless @resource.confirmed?
      # user will require email authentication
      @resource.send_confirmation_instructions({
        client_config: params[:config_name],
        redirect_url: @redirect_url
      })
    end

    if active_for_authentication?
      # email auth has been bypassed, authenticate user
      @client_id, @token = @resource.create_token
      @resource.save!
      update_auth_header
    end

    render_create_success
  else
    clean_up_passwords @resource
    render_create_error

Omniauth 回调 Controller :

def facebook
@user = User.from_facebook(request.env["omniauth.auth"])

# NOTE: redirection here
end

前端

策略:

facebook: {
    client_id: 'CLIENT_ID',
    userinfo_endpoint: 'https://graph.facebook.com/v2.12/me?fields=about,name,picture{url},email,birthday',
    redirect_uri:'http://localhost:3000/omniauth/facebook',
    scope: ['public_profile', 'email', 'user_birthday']
  }

登录方式:

facebookLogin () {
    this.$auth.loginWith('facebook')
    .then((response) => {
      this.$toast.success({
        title: 'Connexion réussie',
        message: 'Vous vous êtes bien connecté.',
        position: 'bottom center',
        timeOut: 3000
      })
    })
    .catch(() => {
      this.$toast.error({
        title: 'Erreur',
        message: 'L\'email ou le mot de passe ne sont pas valides. Vérifiez votre saisie.',
        position: 'bottom center',
        timeOut: 8000
      })
    })
    .finally(() => this.$wait.end('signing in'))
  }

一些事情...

1. Omniauth 回调 Controller 缺少重定向信息(这就是那个注释存在的原因吗？)。如果您使用的是 Devise，它应该在 @user = ... 行下方显示类似 sign_in_and_redirect @user 的内容。
2. Devise 带有内置路由。要使用它们，您必须在 routes.rb 文件中包含类似 devise for :users 的内容。查看 this page 上的“Devise_for magic”部分查看这些内置路由的示例。请注意，您必须配置一些 Devise 模型才能使其正常工作。
3. 运行 rake routes 以查看您定义的路由是否符合您的预期。
4. 如果您无法弄明白，我还使用 Omniauth 创建了一个项目并进行了设计。可以查看我的代码here .
