Question

假设我有一个以

形式出现的回传网址

http://domain/merkin_postback.cgi?id=987654321&new=25&total=1000&uid=3040&oid=123

和其他时间：

http://domain/merkin_postback.php?id=987654321&new=25&total=1000&uid=3040&oid=123

如果我的路线定义是

map.purchase '/merkin_postback', :controller => 'credit_purchases', :action => 'create'

它咆哮上述两种形式中的任何一种都是无效的。

我应该使用正则表达式来识别这两种形式中的任何一种吗？

这不是路由问题，而是内容格式问题。您应该使用respond_to。

class CreditPurchasesController < ActionController::Base
  # This is a list of all possible formats this controller might expect
  # We need php and cgi, and I'm guesses html for your other methods
  respond_to :html, :php, :cgi

  def create
    # ...
    # Do some stuff
    # ...

    # This is how you can decide what to render based on the format
    respond_to do |format|
      # This means if the format is php or cgi, then do the render
      format.any(:php, :cgi) { render :something }

      # Note that if you only have one format for a particular render action, you can do:
      #   format.php { render :something }
      # The "format.any" is only for multiple formats rendering the exact same thing, like your case
    end
  end
end

用正则表达式识别路线？
