ruby-eventmachine将start_server与实例一起使用

Question

我是ruby的新手,也许这是一个非常简单的问题.我想使用eventmachine为我的测试开发一个模拟器.以下文档中的示例我可以这样写:

require 'eventmachine'

class Server< EM::Connection
   def receive_data data
     send_data data
     close_connection_after_writing
   end
end
#Note that this will block current thread.
EventMachine.run {
  EventMachine.start_server '127.0.0.1','8080', Server
}

但我想知道是否有办法使用类的实例,如:

require 'eventmachine'
class Server< EM::Connection
  attr_accessor :response
    def receive_data data
      send_data @response
      close_connection_after_writing
    end
end

server1 = Server.new
server1.response = "foo"

#Note that this will block current thread.
EventMachine.run {
  EventMachine.start_server '127.0.0.1','8080', server1
}

我尝试阅读源代码..但对我来说太难了.我肯定错过了一些东西,但我不知道怎么做这样的事情.

Answer 1

正如我所说,有些东西我不见了.

您可以为要实例化的类添加参数:

  class Server< EM::Connection
    def initialize par
       puts "I'm server number#{par}"
    end
    def receive_data data
      send_data data
      close_connection_after_writing
    end
 end

EventMachine.run {
  EventMachine.start_server '127.0.0.1','8080', Server,1
}

EventMachine.run {
  EventMachine.start_server '127.0.0.1','8080', Server,2
}

所以我将使用参数自定义实例行为
