Devise/Google OAuth 2:找不到.身份验证passthru

Question

我在omn​​iauth-google-oauth2 gem 的自述文件中遵循了教程,当我点击我的root(@ pages#home)上的链接时<%= link_to "Sign up with Google", user_google_oauth2_omniauth_authorize_path %>,我收到错误:

未找到.身份验证passthru.

我已经确认ENV vars在那里.我一直在寻找类似的主题,没有运气.知道我做错了什么吗？

在路线:

Rails.application.routes.draw do
      devise_for :users, controllers: { :omniauth_callbacks => "users/omniauth_callbacks" }

我的omniauth_callbacks_controller位于 /controllers/users/omniauth_callbacks_controller.rb

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def google_oauth2
      # You need to implement the method below in your model (e.g. app/models/user.rb)
      @user = User.from_omniauth(request.env["omniauth.auth"])

      if @user.persisted?
        flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Google"
        sign_in_and_redirect @user, :event => :authentication
      else
        session["devise.google_data"] = request.env["omniauth.auth"].except(:extra) #Removing extra as it can overflow some session stores
        redirect_to new_user_registration_url, alert: @user.errors.full_messages.join("\n")
      end
  end
end

在我的devise.rb档案中:

config.omniauth :google_oauth2, ENV["GOOGLE_CLIENT_ID"], ENV["GOOGLE_CLIENT_SECRET"], {
      name: 'my-project',
      scope: 'email',
      prompt: 'select_account',
      image_aspect_ratio: 'original',
      image_size: 100,
      ssl_verify: false
  }

在我的User.rb中:

devise :rememberable, :validatable, :omniauthable, :omniauth_providers => [:google_oauth2]

   def self.from_omniauth(access_token)
         data = access_token.info
         user = User.where(:email => data["email"]).first

         # Uncomment the section below if you want users to be created if they don't exist
         # unless user
         #     user = User.create(name: data["name"],
         #        email: data["email"],
         #        password: Devise.friendly_token[0,20]
         #     )
         # end

         user
     end

Answer 1

我解决了这个问题，添加以下内容config/initializers/omniauth.rb：

OmniAuth.config.allowed_request_methods = %i[get]

解释：

以上是https://github.com/zquestz/omniauth-google-oauth2#usage中显示的配置：

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :google_oauth2, ENV['GOOGLE_CLIENT_ID'], ENV['GOOGLE_CLIENT_SECRET']
end
OmniAuth.config.allowed_request_methods = %i[get]

但没有

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :google_oauth2, ENV['GOOGLE_CLIENT_ID'], ENV['GOOGLE_CLIENT_SECRET']
end

因为您的config/initializers/devise.rb：

  config.omniauth :google_oauth2, ENV["GOOGLE_CLIENT_ID"], ENV["GOOGLE_CLIENT_SECRET"], {
      name: 'my-project',
      scope: 'email',
      prompt: 'select_account',
      image_aspect_ratio: 'original',
      image_size: 100,
      ssl_verify: false
  }

值得检查的是您的 Google OAuth 重定向 URI 是否正确，并且包含/callback在末尾。
