如何将recaptcha与设计集成？

Question

我正在使用Devise进行身份验证，并希望在注册表单中添加验证码，我读过有关recaptcha的内容，有人可以告诉我们如何整合这两种情况吗？

Answer 1

快速谷歌在设计维基上显示了一个页面 - https://github.com/plataformatec/devise/wiki/How-To:-Use-Recaptcha-with-Devise

你看过那个吗？

Answer 2

1. obtain a reCAPTCHA API key
2. Install gem ReCaptcha
3. 将<%= recaptcha_tags %>添加到您的视图（views/devise/registrations/new）

4. 创建文件（在config/initializers中）recaptcha.rb并添加以下代码：

   Recaptcha.configure do |config|
     config.public_key  = 'Your public key'
     config.private_key = 'Your private key'
   end
   

5. 在控制器中创建：registrations_controller.rb并添加此代码

   class RegistrationsController < Devise::RegistrationsController
     def create
       if verify_recaptcha
         super
       else
         build_resource(sign_up_params)
         clean_up_passwords(resource)
         flash.now[:alert] = "There was an error with the recaptcha code below. Please re-enter the code."
         flash.delete :recaptcha_error
         render :new
       end
     end
   end
   

6. 更新您的设计路线：

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