ruby-on-rails - Google Recaptcha with rails Devise

Question

我正在使用 devise 将 google recaptcha 添加到我的 rails 应用程序中。我做了以下事情:

#In my gemfile:
    gem "recaptcha", require: "recaptcha/rails"

在我的初始化器中:

#In config/initializers/recaptcha.rb
Recaptcha.configure do |config|
  config.site_key  = '********************'
  config.secret_key = '********************'
  # Uncomment the following line if you are using a proxy server:
  # config.proxy = 'http://myproxy.com.au:8080'
end

在 application.html.erb 布局文件中:

<script src='https://www.google.com/recaptcha/api.js'></script>

在设计/注册/new.html.erb

  <%= flash[:recaptcha_error] %>
  <%= recaptcha_tags %>

注册 Controller

class RegistrationsController < Devise::RegistrationsController
    prepend_before_action :check_captcha, only: [:create] # Change this to be any actions you want to protect.
  before_action :configure_permitted_parameters, :only => [:create]


  protected

    def configure_permitted_parameters
      devise_parameter_sanitizer.permit(:sign_up) { |u| u.permit(:email, :password, :password_confirmation, :remember_me,:username, :name, :country, :sex, :age_group, :race) }
      devise_parameter_sanitizer.permit(:account_update) { |u| u.permit(:email, :password, :remember_me,:username, :name, :country, :sex, :age_group, :race) }
    end

  private
    def check_captcha
      unless verify_recaptcha
        self.resource = resource_class.new configure_permitted_parameters
        #resource.validate # Look for any other validation errors besides Recaptcha
        respond_with_navigational(resource) { render :new }
      end
  end
end

当我注册时，页面被重定向到我的注册页面本身。在 recaptcha 元素上显示 recaptcha 错误消息。服务器日志显示:

用户未添加到数据库。无法完成注册。请解决这个问题。提前致谢。

不知道为什么这不起作用，如果您的配置正常然后也不起作用然后尝试注释掉 check_captcha 方法然后重写 create 方法，如下所示

def create
    if verify_recaptcha
      super
    else
        flash.now[:error] = "Recaptcha cannot be blank; please try again"
        render :new
    end
end

和路线

devise_for :users, controllers: { registrations: 'registrations' }
