Pou*_*oul 36 ruby rack sinatra eventmachine websocket
我一直在使用Sinatra一段时间,我想通过websockets推送数据,为我的web-app添加一些实时功能.
我已经成功地使用了gem'em-websocket',但是还没能编写一个带有sinatra Web服务器和web-socket服务器的ruby文件.
我试过旋转跑!或者开始!在单独的线程中关闭方法但没有成功.
有没有人得到这个工作？
我希望将它们放在同一个文件中,然后在两个服务器之间共享变量.
谢谢!

没试过,但不应该太难:
require 'em-websocket'
require 'sinatra/base'
require 'thin'
EM.run do
class App < Sinatra::Base
# Sinatra code here
end
EM::WebSocket.start(:host => '0.0.0.0', :port => 3001) do
# Websocket code here
end
# You could also use Rainbows! instead of Thin.
# Any EM based Rack handler should do.
Thin::Server.start App, '0.0.0.0', 3000
end
另外,Cramp有一个websocket实现,可以直接使用Thin/Rainbows!您可能能够解压缩,因此您甚至不需要在另一个端口上运行服务器.

谢谢康斯坦丁......这很有效!我不得不稍微调整你的代码.我添加了评论,我改变了它.

EventMachine::WebSocket.start(:host => '0.0.0.0', :port => 8080) do |ws| # <-- Added |ws|

ws.onopen {
ws.send "connected!!!!"
}
ws.onmessage { |msg|
puts "got message #{msg}"
}
ws.onclose {
ws.send "WebSocket closed"
}
end
# You could also use Rainbows! instead of Thin.
# Any EM based Rack handler should do.
App.run!({:port => 3000}) # <-- Changed this line from Thin.start to App.run!

我偶然发现了这个websocket-rack github项目,该项目基本上是一个机架化的em-websocket,实际上它可以与Sinatra应用程序很好地并排运行.这是我的config.ru:
require 'rubygems'
require 'rack/websocket'
require 'sinatra/base'
class WebSocketApp < Rack::WebSocket::Application
# ...
end
class SinatraApp < Sinatra::Base
# ...
end
map '/ws' do
run WebSocketApp.new
end
map '/' do
run SinatraApp
end
玩得开心!

我一直在使用sinatra-websocket.它允许您在与Sinatra相同的进程和相同的端口上运行websocket服务器.
免责声明:我是维护者.
require 'sinatra'
require 'sinatra-websocket'
set :server, 'thin'
set :sockets, []
get '/' do
if !request.websocket?
erb :index
else
request.websocket do |ws|
ws.onopen do
ws.send("Hello World!")
settings.sockets << ws
end
ws.onmessage do |msg|
EM.next_tick { settings.sockets.each{|s| s.send(msg) } }
end
ws.onclose do
warn("websocket closed")
settings.sockets.delete(ws)
end
end
end
end

仅供参考,您还可以将Padrino应用与EventMachine一起使用(因为它们是Sinatra应用的子集):
require 'rubygems'
require 'eventmachine'
require 'padrino-core'
require 'thin'
require ::File.dirname(__FILE__) + '/config/boot.rb'
EM.run do
Thin::Server.start Padrino.application, '0.0.0.0', 3000
end
干杯,迈克
