Sinatra 是驼峰式所有标题名称，导致“P3P”出现问题。代码：

require 'rubygems'
require 'sinatra'

configure :production do
  # Configure stuff here you'll want to
  # only be run at Heroku at boot

  # TIP:  You can get you database information
  #       from ENV['DATABASE_URI'] (see /env route below) 
end

# Quick test
get '/track' do
  #response.headers['Cache-Control'] = 'public, max-age=300'
  response.set_cookie("visited",1)
  response['this-that'] = "CP=\"CAO DSP COR CURa ADMa DEVa OUR IND PHY ONL UNI COM NAV INT DEM PRE\""
  response['P3P'] = "CP=\"CAO DSP COR CURa ADMa DEVa OUR IND PHY ONL UNI COM NAV INT DEM PRE\""
  "SUCCESS"
end

给我吗

如您所见this-that，被重写为This-That并被P3P重写为P3p. 这是我的宝石清单：

如何阻止 sinatra 重写 cookie 名称。有没有我可以做的猴子补丁？

HTTP 标头名称应该不区分大小写，所以理论上这应该不是问题——P3p应该和P3P.

在您的情况下，标头正在由 Webrick 服务器更改，而不是 Sinatra。更改为另一台服务器，例如 Thin（不会更改标头）将是最简单的解决方法（使用 Thin 而不是 Webrick 还有其他好处）。

如果你真的需要继续使用 Webrick，你可以考虑修补WEBrick::HTTPResponse. 您必须小心，因为 Webrick 将标头名称小写以处理重复项，因此您可能必须考虑这一点。
