Using rack-proxy with Rails to access Faye

Question

I have a rails app which provides real-time functionality through Faye. My clients are going to access the Faye server through example.com:9292/faye . Instead of using that address and revealing my machine's open ports, I am trying to add a rack middleware and by using 'rack-proxy' gem, proxy my example.com/faye requests to example.com:9292/faye . My Rails middleware code looks like this:

class FayeProxy < Rack::Proxy
  def rewrite_env(env)
    request = Rack::Request.new(env)
    if request.path =~ %r{^/faye}
      env["HTTP_HOST"] = "localhost:9292"
    end
    env
  end
 end

Also I added the middleware to config/application.rb by config.middleware.use "FayeProxy" , but when I run my rails server I get the following error:

/gems/ruby-1.9.3-p194/gems/rack-proxy-0.5.0/lib/rack/proxy.rb:12:in 'initialize': undefined method `key?' for # (NoMethodError)

and even if I remove meta_request gem I will get

*/gems/ruby-1.9.3-p194/gems/rack-proxy-0.5.1/lib/rack/proxy.rb:12:in initialize': undefined method key?' for # (NoMethodError) *

Any help is really appreciated if anybody has experienced this before or knows the solution.

Ps I'm using Rails 3.2.13, rack 1.4.5, rack-proxy 0.5.1.

似乎机架代理不应被视为中间件，而应通过此处所述的路径进行安装： http : //inductor.induktiv.at/blog/2010/05/23/mount-rack-apps-in- rails-3 / 。

I know this is old, but I was just having a similar issue, but I suspect that the folder you faye_proxy.rb is in is not included in rails by default.

Adding an initializer maybe ./config/initializers/proxy.rb which contains require "#{Rails.root}/lib/faye_proxy.rb" Replace lib with wherever you put the proxy.
