当我在AppFog上访问Sinatra应用程序时,会显示"禁止"消息

Question

我上传了一个简单的Sinatra应用程序到AppFog.它在我的本地机器上运行良好.但在将应用程序上传到AppFog后,当我访问AppFog域时,会显示带有"禁止"消息的页面.

这些是appFog日志:

我没有Rack::Protection::IPSpoofing在我的代码中使用,但我得到了这些错误.Rack::Utils用于帮助程序块.这是导致问题吗？

我写的唯一Ruby代码如下:

require 'sinatra'
require 'data_mapper'
require 'builder'
require 'sinatra/flash'
require 'sinatra/redirect_with_flash'
require 'haml'

enable :sessions

SITE_TITLE = "Recall"
SITE_DESCRIPTION = "'cause you're too busy to remember"

DataMapper::setup(:default, "sqlite3://#{Dir.pwd}/recall.db")

class Note
  include DataMapper::Resource
  property :id, Serial
  property :content, Text, :required => true
  property :complete, Boolean, :required => true, :default => false
  property :created_at, DateTime
  property :updated_at, DateTime
end

DataMapper.finalize.auto_upgrade!

helpers do
  include Rack::Utils
  alias_method :h, :escape_html
end

get '/' do
  @notes = Note.all :order => :id.desc
  @title = 'All Notes'
  if @notes.empty?
    flash[:error] = 'No notes found. Add your first below.'
  end
  haml :home
end

我怎么解决这个问题？感谢您的任何建议.

这是一个简单的修复,尝试添加这个:

set :protection, :except => :ip_spoofing

我们正在修补我们的nginx以解决这个问题,但这项工作现在将有所帮助.
