Routes

小心地使用 Match（Rails 3 已实现）

Rails 3 提供了 match 方法供我们自定义 routes，然而我们要小心使用它以避免“跨站脚本攻击”（XSS Attack）。比如像这样的 routes：

注：（r3 代表 Rails 3，r4 代表 Rails 4）

# routes.rb

jimhj

require 'mini_magick'

class CustomAdmin::MiniCaptchaController < CustomAdmin::ApplicationController

 

  before_filter :clear_captcha_session, :only => :mini_captcha

require 'socket'
require 'rubygems'
require 'eventmachine'
require 'logger'
require 'active_record'
# Rails -v: 2.3.5

 REF_RAILS_ROOT_DIR = File.expand_path(File.join(File.dirname(__FILE__),'..','..'))

class MobileBalanceServer < EventMachine::Connection

jimhj

# coding: utf-8
module SimpleUpload
  class Base
    class << self

      def max_size
        10485760 #(10M)
      end

    # load logger
    if @cfg['log']['file']
      require 'logger'
