rails验证码

1.安装包

gem 'rucaptcha'
gem 'dalli'

2.配置路由（最新版本的不用配置路由）

mount RuCaptcha::Engine => "/rucaptcha"

3.controller部分

def create
    @user = User.new(user_params)
    if  verify_rucaptcha?(@user)&&@user.save
    ......

4.view部分

  <div class="form-group ">
     <%= rucaptcha_input_tag( class:'form-control rucaptcha-text') %>
     <a href="#" class='rucaptcha-image-box'><%= rucaptcha_image_tag(class:'rucaptcha-image', alt: 'Captcha') %></a>
  </div>

5.实现点击图片刷新验证码

 #点击验证码刷新
  $(".rucaptcha-image").click ->
    img = $(this)
    currentSrc = img.attr('src');
    img.attr('src', currentSrc.split('?')[0] + '?' + (new Date()).getTime());
    return false
