Question

I want to send a hash populated with data from a EventMachine client to a server. The problem is that the server receive_date method just prints a string.

The server:

  def receive_data(data)
    send_data("Ready")
    puts data[:total]
  end

The client:

def receive_data(data)
  send_data( get_memory() )
end

def get_memory
  sigar = Sigar.new
  mem = sigar.mem
  swap = sigar.swap
  memory = { :total => (mem.total / 1024), :cat => "kwiki", :mouse => "squeaky" }
end

This line: puts data[:total]

prints only nil

Answer 1

Why don’t you convert the Hash to a JSON string before sending it, and convert it back to a Hash when the server receive it?
