Sinatra是所有标题名称的骆驼套管,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

您可以看到this-that
被重写为This-That
而P3P
被重写为P3p
。这是我的宝石列表:

如何阻止sinatra重写cookie名称。我能做一个猴子补丁吗?
答案 0 :(得分:5)
HTTP header names should be case insensitive,理论上这应该不是问题 - P3p
应该与P3P
一样有效。
在你的情况下,标题是altered by the Webrick server,而不是Sinatra。更改为其他服务器(如Thin(不会更改标题))将是最简单的修复(使用Thin over 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
。你必须要小心,因为Webrick会对标题名称进行下调以处理重复项,因此你可能需要考虑到这一点。
