Devise 2.2 + Google OAuth2未定義方法“ serialize_into_session”

Question

我安裝了Devise，並正在為我的應用程序工作。 當我添加

gem omniauth-google-oauth2

我在控制器sign_in_and_redirect方法中收到錯誤。

錯誤：

NoMethodError (undefined method `serialize_into_session' for String:Class):
  app/controllers/users/omniauth_callbacks_controller.rb:9:in `google_oauth2'

碼：

omn​​iauth_callbacks_controller.rb

def google_oauth2
    @user = User.find_for_google_oauth2(request.env["omniauth.auth"], current_user)
    if @user.persisted?
      flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Google"
      sign_in_and_redirect sites_path, :event => :authentication
    else
      session["devise.google_data"] = request.env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
end

user.rb

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(email: data["email"],
                         password: Devise.friendly_token[0, 20]
      )
    end
    user
end

devise.rb

require "omniauth-google-oauth2"
config.omniauth :google_oauth2, 'CLIENT_ID', 'CLIENT_SECRET', {access_type: "offline", approval_prompt: ""}

如果我錯過了什么，請告訴我。

Answer 1

您的配置很好，但我在這種情況下使用的是omniauth-google-oauth2 ，這是https://rubygems.org/gems/omniauth-openid 。

將以下內容添加到您的/config/initializer/devise.rb中：

require 'openid/store/filesystem'
config.omniauth :open_id, :store => OpenID::Store::Filesystem.new('/tmp'), :name => 'google', :identifier => 'https://www.google.com/accounts/o8/id', :require => 'omniauth-openid'

然后在您的omniauth_callbacks_controller.rb內部，將User.find_for_google_oauth2...方法更改為User.find_for_open_id...

在您的user模式改變self.find_for_google_oauth2通過self.find_for_open_id 。

請嘗試使用此寶石！
