我有一个recaptcha的问题，我按照下一个教程：
https://github.com/ambethia/recaptcha
在我的应用程序中我有下一个：
- 在文件config/initializers/recaptcha.rb
Recaptcha.configure do |config|
config.site_key = Rails.application.secrets.recaptcha_site_key
config.secret_key = Rails.application.secrets.recaptcha_secret_key
config.proxy = ‘http://www.google.com/recaptcha/api/verify’
end
gem 'bootstrap-sass', '~> 3.3.7'
gem 'jquery-rails', '~> 4.3'
gem 'devise', '~> 4.2'
gem 'toastr-rails', '~> 1.0'
gem 'recaptcha', require: 'recaptcha/rails'
gem 'bcrypt'
.
.
.
在文件app / views / devise / registrations / new.html.erb中
<div class="row">
<div class="col-md-4 col-md-offset-4">
<h2 class="text-center">Sign up</h2>
<br/>
<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
<%= render 'shared/devisemes' %>
<div class="form-group">
<%= f.text_field :fullname, autofocus: true, placeholder: "Full Name", class: "form-control" %>
</div>
<div class="form-group">
<%= f.email_field :email, autofocus: true, placeholder: "Email", class: "form-control" %>
</div>
<div class="form-group">
<%= f.password_field :password, autocomplete: "off", placeholder: "Password", class: "form-control" %>
</div>
<br/></br>
<div class="actions">
<%= f.submit "Sign up", class: "btn btn-normal btn-block" %>
</div>
<% end %>
<hr/>
<%= link_to "Sign in with Facebook", user_facebook_omniauth_authorize_path, class: "btn btn-facebook btn-block" %>
</div>
<div class="form-group">
<%= raw receptcha_tags %>
</div>

但我检查它，首先它似乎很好，但它不能正常工作。并且我的应用程序工作正常，在配置recaptcha之前，在配置recaptcha之后它不起作用。我不知道是谁的问题，我认为有更多的配置，因为当你填写表格并填写recaptcha时，你需要传递一个值来检查它，这个值很好，保存表格。如果此表单错误，请不要保存表单并显示错误。
你可以帮助我吗，我是新手，我这样做是按照一个课程，现在我想安装一个recaptcha最小的安全性
我在config/secrets.yml有这个
shared:
recaptcha_site_key: 'site_key here'
recaptcha_secret_key: 'secret_key here'
将校正键放在那里。
您需要在config / initializers / devise.rb中设置设计密钥
config.secret_key = 'secret key goes here'
阅读devise了解更多信息。或者devise tutorial
