为什么当我运行这个 ruby 程序时它总是退出?
这是红宝石程序:
require 'rubygems'
require 'eventmachine'
require 'thread'
require 'sinatra'
Thread.new do
EventMachine.run do
EM.add_periodic_timer(1) do
#do some things
end
end
end
get '/' do
'hello'
end
当我运行它时,我得到了这个:
lynn@ubuntu:~/Test$ ruby em1.rb

当我运行这个 ruby 程序时它退出了,为什么?在这里,我想要一个线程来定期对 http 请求做一些事情!我该怎么做 ?
