Question

我正在尝试在Rails 4应用中截取页面。我尝试了几种方法，但最干净的似乎是使用水豚与恶作剧。

在我的Gemfile中，我有以下内容：

gem 'capybara'
gem 'capybara-screenshot'
gem 'poltergeist'

我的rake任务看起来像这样：

desc "Take a screenshot of top three articles"
task :screenshots => :environment do
  require 'capybara'
  require 'capybara/poltergeist'
  include Capybara::DSL
  Capybara.default_driver = :poltergeist
  Capybara.run_server = false

  articles = Article.order('score DESC').limit(3)

  articles.each do |article|
    visit(article.url)
    screenshot_and_save_page
  end
end

但是，这给了我这样的错误：

Unsafe JavaScript attempt to access frame with URL <someurl> from frame with URL http://static.ak.facebook.com/connect/xd_arbiter.php?version=40#channel=fcf48aa3c&origin=http%3A%2F%2Fwww.independent.co.uk. Domains, protocols and ports must match.

有任何线索如何解决这个问题？

我想我通过添加以下内容解决了这个问题：

Capybara.register_driver :poltergeist do |app|
  Capybara::Poltergeist::Driver.new(app, :js_errors => false)
end
