正如你所看到的那样 – 被重写为This-That并且P3P被重写为P3p.这是我的宝石清单：

如何阻止sinatra重写cookie名称.我能做一个猴子补丁吗？

解决方法 HTTP header names should be case insensitive,所以理论上这应该不是问题 – P3p应该和P3P一样好用.

在你的情况下,标题是altered by the Webrick server,而不是Sinatra.更改为另一个服务器(如Thin(不会更改标头))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.
