map.connect是否在URL中接受通配符样式的格式？ [英] Does map.connect accept a wildcard-style format in the URL?

问题描述

如果我要匹配 x.gif 和 y.gif ，则为可以将URL传递给 map.connect ，其中包含两个文件名的可能性，如下所示：

If I want to match x.gif and y.gif, is it possible to pass a URL to map.connect that encompasses the possibilities of both filenames something like this:

map.connect "public/images/:name.gif",
  :controller => "static_image_controller",
  :action => "serve"

然后接收 param 在我的 StaticImageController 中作为 params [：name] 吗？

And then receive the param in my StaticImageController as params[:name]?

class StaticImageController < ApplicationController
  def serve
    image_name = params[:name]
    image = File.read(File.join(Rails.root, image_name))
    send_data image, :type => "image/gif", :disposition => "inline"
  end
end

除了我在做什么

推荐答案

map.connect '/public/images/:filename', :filename => /\.gif$/

会做到这一点。
