NoMethodError（nil:NilClass 的未定义方法“信息”）“find_for_google_oauth2”

Question

！我正在尝试让同事和学生使用他们的 google 项目帐户注册。我已经得到传递的令牌，但随后出现错误。

app/models/user.rb:70:在`find_for_google_oauth2'

app/controllers/authentications_controller.rb:5:在“创建”中

我的身份验证控制器创建方法

    def create
       auth = request.env[":google_oauth2"]
       @user = User.find_for_google_oauth2(request.env["omniauth.auth"])
       redirect_to root_url, :notice => "Signed in!"
   end

我的用户模型

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]
       user.first_name = auth.info.first_name
       user.last_name = auth.info.last_name   # assuming the user model has a name
       user.image = auth.info.image # assuming the user model has an image
  end
 end

    def self.find_for_google_oauth2(access_token, signed_in_resource=nil)
        data = access_token.info
        user = User.where(:email => data["email"]).first


    unless user
        user = User.create(name: data["name"],
             email: data["email"],
             uid: access_token.uid,
             provider: access_token.provider,
             password: Devise.friendly_token[0,20]
            )
          end
          user
        end

和我的 config/omniauth.rd

require 'omniauth-google-oauth2'

OmniAuth.config.logger = Rails.logger
  OmniAuth.logger.progname = "omniauth"
Rails.application.config.middleware.use OmniAuth::Builder do



    provider :google_oauth2, '***********petnk.apps.googleusercontent.com',
        google_client_secret: '***********',
        prompt: "consent",
        select_account: true,
        scope: 'userinfo.email',
        image_aspect_ratio: 'square',
        image_size: 50
        on_failure { |env|AuthenticationsController.action(:failure).call(env) }

    end

不确定要包含哪些内容来帮助大家帮助我。我是 rails 的新手，在过去的一年里一直在努力学习，因此非常感谢您的帮助。

谢谢

我不得不将我的创建功能从我的身份验证控制器移动到我的 omnicontroller。不太确定为什么这解决了问题，但现在确实如此。
