我正在尝试在我的rails 5应用程序中设置Recaptcha,因为它在文档中有描述,但它失败了。
我使用这个宝石:recaptcha (4.6.6),ruby 2.5.0
和rails 5.1.4
以视图形式:
<%= flash[:recaptcha_error] %>
<%= recaptcha_tags %>
在设计注册控制器:
prepend_before_action :check_captcha, only: :create
private
def check_captcha
unless verify_recaptcha
self.resource = resource_class.new sign_up_params
resource.validate # Look for any other validation errors besides Recaptcha
respond_with_navigational(resource) { redirect_to new_user_registration_path }
end
end
在我的初始化者/ recaptcha.rb
中Recaptcha.configure do |config|
config.site_key = Rails.application.config_for(:recaptcha)['site_key']
config.secret_key = Rails.application.config_for(:recaptcha)['secret_key']
end
在我的recaptcha.yml中:
default: &default
site_key: <%= ENV["RECAPTCHA_SITE_KEY"] %>
secret_key: <%= ENV["RECAPTCHA_SECRET_KEY"] %>
development:
<<: *default
test:
<<: *default
staging:
<<: *default
production:
<<: *default
在/ etc / environments中:
# RECAPTCHA
RECAPTCHA_SITE_KEY=6Lfg3ksUAAAAABOD_OXCtPO60*******
RECAPTCHA_SECRET_KEY=6Lfg3ksUAAAAAOmFGdAxdo8*******
问题
将ENV变量添加到/etc/environments
后,我使用以下命令导出它:
for line in $( cat /etc/environment ) ; do export $line ; done
然后我检查Recaptcha模块配置是否正确:
/home/deploy/apps/app_name/current$ bundle exec rails c
Loading staging environment (Rails 5.1.4)
2.5.0 :001 > Recaptcha::Configuration.new
=> #<Recaptcha::Configuration:0x0000000006601908 @skip_verify_env=["test", "cucumber"], @handle_timeouts_gracefully=true, @secret_key="6Lfg3ksUAAAAAOmFGdAxdo8H*************", @site_key="6Lfg3ksUAAAAABOD_OXCtPO*************">
2.5.0 :002 > Recaptcha::Configuration.new.site_key!
=> "6Lfg3ksUAAAAABOD_OXCtPO*************"
另外,当我运行printenv
命令时,我看到这些ENV变量(所以它真的被加载了)
之后,我重新启动了rails并出现了错误
未指定网站密钥。

我仍然不知道“No site key specified”错误的原因是什么。
我真的不喜欢gem 'recapthca'
直接使用ENV变量,
我也花了太多时间进行调查。
所以,我决定不使用这个gem并编写我自己的代码。
我在我的应用程序中只使用Invisible Recaptcha。
配置文件(加载机密密钥和网站密钥)
# /config/recaptcha.yml
default: &default
site_key: <%= ENV["RECAPTCHA_SITE_KEY"] %>
secret_key: <%= ENV["RECAPTCHA_SECRET_KEY"] %>
development:
<<: *default
test:
<<: *default
staging:
<<: *default
production:
<<: *default
应用程序助手(带Recaptcha助手的按钮)
# /app/helpers/application_helper.rb
module ApplicationHelper
def submit_with_recaptcha(text, custom_options)
unless custom_options[:data].has_key?(:form_id)
raise "Data Form Id option not found ('{data: {form_id: 'id_without_dash'}')."
end
options = {
type: 'button',
data: {
form_id: custom_options[:data][:form_id],
sitekey: recaptcha_site_key,
callback: "submit#{custom_options[:data][:form_id].camelize}#{Time.current.to_i}"
},
class: (custom_options[:class].split(' ') + ['g-recaptcha']).uniq.join(' ')
}
script_code = <<-SCRIPT
function #{options[:data][:callback]}() {
document.getElementById('#{options[:data][:form_id]}').submit();
}
SCRIPT
javascript_tag(script_code) + content_tag(:div, class: 'recaptcha_wrapper'){ submit_tag(text, options) }
end
private
def recaptcha_site_key
Rails.application.config_for(:recaptcha)['site_key']
end
end
验证服务(因为它使用外部API)
# app/services/google_recaptcha/verification.rb
module GoogleRecaptcha
# https://developers.google.com/recaptcha/docs/verify
class Verification
# response - params['g-recaptcha-response'])
def self.successful?(recaptcha_params, remoteip)
verify_url = URI.parse('https://www.google.com/recaptcha/api/siteverify')
verify_request = Net::HTTP::Post.new(verify_url.path)
verify_request.set_form_data(
response: recaptcha_params,
secret: secret_key,
remoteip: remoteip
)
connection = Net::HTTP.new(verify_url.host, verify_url.port)
connection.use_ssl = true
Rails.logger.info '[RECAPTCHA] Sending verification request.'
verify_response = connection.start { |http| http.request(verify_request) }
response_data = JSON.parse(verify_response.body)
Rails.logger.info "[RECAPTCHA] Verification response is#{' not' unless response_data['success']} successful."
response_data['success']
end
private
def self.secret_key
Rails.application.config_for(:recaptcha)['secret_key']
end
end
end
控制器关注(before_action中的Recaptcha验证)
# app/controllers/concerns/recaptchable.rb
module Recaptchable
extend ActiveSupport::Concern
included do
before_action :verify_recaptcha, only: [:create]
end
private
def verify_recaptcha
unless GoogleRecaptcha::Verification.successful?(recaptcha_params['g-recaptcha-response'], request.remote_ip)
render :new
return
end
end
def recaptcha_params
params.permit(:'g-recaptcha-response')
end
end
<强>用法强>
添加您对控制器的关注:
class MyController < ShopController
include Recaptchable
end
将www.google.com/recaptcha/api.js
javascript添加到您的网页
将submit_with_recaptcha
帮助器添加到表单
<%= form_for @delivery, url: users_delivery_path, method: 'post' do |f| %>
<%= submit_with_recaptcha t('order.deliver.to_confirmation'), data: {form_id: 'new_delivery'}, class: 'btn-round' %>
<% end %>
<%= javascript_include_tag "https://www.google.com/recaptcha/api.js?hl=#{I18n.locale}", 'data-turbolinks-track': 'reload' %>
就是这样。

注意:我在这里发布此答案,以供可能发现此问题的人参考。这是我解决问题的方法。
我将local_env.yml用于环境变量。我刚开始使用gem,然后将RECAPTCHA_SITE_KEY和RECAPTCHA_SECRET_KEY添加到local_env.yml。我遇到了同样的错误。
花了一点时间才知道宝石直接使用了变量。我最终将以下语句放在~/.bashrc
中,类似于文档中所说的内容,但在值两边没有引号。
export RECAPTCHA_SITE_KEY=6Lc6BAAAAAAAAChqRbQZcn_yyyyyyyyyyyyyyyyy
export RECAPTCHA_SECRET_KEY=6Lc6BAAAAAAAAKN3DRm6VA_xxxxxxxxxxxxxxxxx
我在Heroku上托管我的应用程序。我执行了以下终端命令以在Heroku中设置环境变量。
heroku config:set RECAPTCHA_SITE_KEY=‘6Lc6BAAAAAAAAChqRbQZcn_yyyyyyyyyyyyyyyyy’
heroku config:set RECAPTCHA_SECRET_KEY=‘6LcGuI4U6Lc6BAAAAAAAAKN3DRm6VA_xxxxxxxxxxxxxxxxxAAAAGAWMYRKFGfHUCSD0SPrMX2lfyl9’
答案 2 :(得分:0)
您在使用nginx吗? Nginx删除了ENV变量(TZ除外),并且recapcha宝石似乎对此特别敏感。根据经验,当使用dotenv
宝石时,其他ENV变量正常工作时,将忽略重新配置ENV变量。
您可以通过在enginx.conf的顶部添加env变量来解决此问题。
env RECAPTCHA_SITE_KEY=value1;
env RECAPTCHA_SECRET_KEY=value2;
答案 3 :(得分:0)
如果有人正在寻找用于设置Recaptcha密钥的Rails 5.2解决方案,我会在此处发布。该解决方案利用了新的config / master.key和config / credentials.yml.enc加密文件。
通过在本地终端中编辑文件,将Recaptcha密钥添加到certificate.yml.enc文件中:
EDITOR="vim" rails credentials:edit
将密钥添加到凭据文件后(请参见下面的示例),保存并退出文件。退出后,然后将自动对certificate.yml.enc文件进行加密。 master.key是应用程序解密所必需的。加密之前:
recaptcha_site_key: 6Lc6BAAAAAAAAChqRbQZcn_yyyyyyyyyyyyyyyyy
recaptcha_secret_key: 6Lc6BAAAAAAAAKN3DRm6VA_xxxxxxxxxxxxxxxx
3.在Rails应用程序中创建一个名为config / recaptcha.rb的文件,并向其中添加以下代码:
Recaptcha.configure do |config|
config.site_key = Rails.application.credentials.dig(:recaptcha_site_key)
config.secret_key = Rails.application.credentials.dig(:recaptcha_secret_key)
end
此解决方案在本地和生产环境中的Ubuntu / nginx上均可使用。您不需要gem或环境变量即可工作。如果master.key解密失败,则可能需要删除certificate.yml.enc文件,甚至可能要删除master.key文件,然后在本地重复此过程(EDITOR =“ vim” rails certificate:edit等)。在将新的master.key复制到生产并重新部署之前。
