我们有一个由 rails 3.1.8 开发的工具，可以将产品信息导出到 ms word，如果产品线有一些更新，产品所有者可以单击 word 中的链接在我们的应用程序中编辑产品详细信息。

问题是：当我们点击word中的链接时，它会转到主页而不是编辑页面。

所以我们使用 devise 在路由中执行身份验证：

devise_for :users do
  get "login" => "devise/sessions#new"
  get "logout" => "devise/sessions#destroy"
end

Microsoft Office 有自己的机制来识别链接（即协议发现）。

这需要在 Rails 中以不同方式处理。MS office 使用 OPTIONS http 方法发出请求，然后一直到第一个 200 响应，然后在浏览器窗口中打开相同的 url（在您的情况下为重定向的 url）。

在这里，Devise 会跟踪 session 中的 requested_url，但浏览器会使用登录 url 启动新会话，因此 devise 无法将其重定向回 ms doc 中的链接点击。

这是处理此案的一个很好的解决方案 http://rails.nuvvo.com/lesson/2318-dealing-with-microsoft-office-protocol-discovery-in-rails
