Simple Rails 4 ActionController ::实例不使用Apache + Passenger

我正在尝试将我们的环境转移到Rails 4并解决所有问题.遗憾的是,我们目前使用的是Centos 5.5,因此只需要一些障碍就可以让Rails启动并运行.这包括安装python 2.6和node.js以使extjs正常工作.

而现在我被卡住了.使用全新的rails 4.0.2应用程序,我有简单的ActionController :: Live示例在Puma的开发中正常运行.但在Apache + Passenger的生产中,它根本不会将数据发送回浏览器(Firefox)

production.rb有

config.allow_concurrency = true

这是index.html中的HTML/JS.

这是控制器:

class LiveController < ApplicationController
  include ActionController::Live
  respond_to :html
  def feed
    response.headers['Content-Type']      = 'text/event-stream'
    response.headers['X-Accel-Buffering'] = 'no'

    while true do 
      response.stream.write "id: 0\n"
      response.stream.write "event: update\n"
      data = {time: Time.now.to_s}.to_json
      response.stream.write "data: #{data}\n\n"
      sleep 2
    end
  end
end

我可以看到请求在Firebug中发送到服务器通知spinner on/feed:

Apache/Passenger Config有这个:

LoadModule passenger_module /usr/local/ordernow/lib/ruby/gems/2.0.0/gems/passenger-4.0.27/buildout/apache2/mod_passenger.so
PassengerRoot /usr/local/ordernow/lib/ruby/gems/2.0.0/gems/passenger-4.0.27
PassengerDefaultRuby /usr/local/ordernow/bin/ruby
RailsAppSpawnerIdleTime 0
PassengerMinInstances 1

Apache日志没有显示任何内容.就像它永远不会连接到服务器.另一个奇怪的事情是命令行的卷曲起作用:

     curl -k -i -H "Accept: text/event-stream" https://10.47.47.44:8446/feed

id: 0
event: update
data: {"time":"2014-03-27 10:52:54 -0600"}

我认为它必须是Apache的东西,但我不确定.

好吧,我终于通过一堆谷歌搜索来解决这个问题,这使我看到mod_deflate(用于压缩对浏览器的响应)将干扰非缓冲响应,如text/event-stream.

看着我的httpd.conf,我发现了这个:

SetOutputFilter DEFLATE
SetEnvIfNoCase Request_URI \.(?:gif|jpg|png|ico|zip|gz)$ no-gzip

# Restrict compression to these MIME types
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE text/css

# Level of compression (Highest 9 - Lowest 1)
DeflateCompressionLevel 9

SetOutputFilter DEFLATE 打开所有响应的压缩,使其余的AddOutputFilterByType指令不再需要.这显然是httpd.conf中的一个错误.我删除了这一行,并验证压缩仍然适用于html页面.

现在一切都很棒!以及我试图在第一时间开始使用的仪表板工具.
