仅将某些中间件用于特定的Rack网站 [英] use some Middleware only for specific Rack website

问题描述

我有一个运行多个网站的机架服务器.

I have a Rack server where I run multiple websites.

use Rack::Session::Cookie

app = lambda do |env|

  case

  # Kek Mobile
  when env['HTTP_HOST'] =~ /mobi.kek.com/ 
    require ::File.expand_path(::File.join(::File.dirname(__FILE__),'code','kek_mobile','main.rb'))
    selectedApp = KekMobile.new

  # Kek Facebook App
  when env['HTTP_HOST'] =~ /fb.kek.com/ 
    require ::File.expand_path(::File.join(::File.dirname(__FILE__),'code','facebook','main.rb'))
    selectedApp = Facebook.new

  else #we launch the corp website
    require ::File.expand_path(::File.join(::File.dirname(__FILE__),'code','corp','main.rb'))
    selectedApp = Corp.new

  end

  selectedApp.call env
end

run app

我正在尝试使用一些Rack中间件，但是我不想在所有网站上都使用它们.例如，我只想将OAuth中间件仅用于facebook应用程序网站. 我试图在when语句或网站main.rb文件中使用中间件，但是它不起作用. 是否可以启动网站特定的中间件?

I am trying to use some Rack Middleware but I don't want to use them for all the websites. For example I would like to use an OAuth Middleware for only the facebook app website. I tried to use the Middleware in the when statement or in the website main.rb file but it's not working. Is it possible to launch website specific Middleware?

谢谢.

推荐答案

我相信URLMap中间件将解决您的问题，或者至少使您处于正确的轨道.

I believe the URLMap middleware will solve your problem, or at least put you on the right track.

• 示例: http://blog.ninjahideout.com/posts/rack-urlmap-and-kicking-ass
• 官方文档: http://rack.rubyforge.org/doc/classes /Rack/URLMap.html

• Examples: http://blog.ninjahideout.com/posts/rack-urlmap-and-kicking-ass
• Official docs: http://rack.rubyforge.org/doc/classes/Rack/URLMap.html

如您所见，URLMap允许您为每个应用程序提供不同的中间件管道:

As you can see, URLMap lets you supply a different middleware pipeline for each app:

use Rack::Lint

map "/" do
  use Rack::CommonLogger
  run our_test_app
end

map "/lobster" do
  use Rack::ShowExceptions
  run Rack::Lobster.new
end

在您的示例中，很明显，这将无法直接运行，因为您是基于HTTP主机进行映射的.但是，官方文档提到:如果URL以http://或https://开头，则支持HTTP/1.1主机名."因此，也许您可​​以调用map "http://mobi.kek.com"和map "http://fb.kek.com".

From your example, it's clear that this will not work directly, since you are mapping based on the HTTP host. However, the official docs mention, "Support for HTTP/1.1 host names exists if the URLs start with http:// or https://." So, perhaps you can call map "http://mobi.kek.com" and map "http://fb.kek.com".
