Question

我正在使用带有ruby-amqp gem的rails。它与rails app本身一起工作正常，但是android java客户端无法接收消息。

android客户端基于此 http://simonwdixon.wordpress.com/2011/06/03/getting-started-with-rabbitmq-on-android-part-1/

mConsumer = new MessageConsumer("192.168.1.123", "nodes.metadata", "fanout");

我的ruby实现基于此

EventMachine.next_tick do
  connection = AMQP.connect(:host => '127.0.0.1')
  channel  = AMQP::Channel.new(connection)
  exchange = channel.fanout("nodes.metadata")

  channel.queue("joe", :auto_delete => true).bind(exchange).subscribe do |payload|
    puts "#{payload} => joe"
  end

  channel.queue("aaron", :auto_delete => true).bind(exchange).subscribe do |payload|
    puts "#{payload} => aaron"
  end

  channel.queue("bob", :auto_delete => true).bind(exchange).subscribe do |payload|
    puts "#{payload} => bob"
  end

  exchange.publish("BOS")

  # disconnect & exit after 2 seconds
  EventMachine.add_timer(2) do
    exchange.delete

    # connection.close { EventMachine.stop }
  end
end

当我运行它时工作正常我在终端获得发布消息但是当android正在监听rabbitmq时，我没有在终端中得到消息，而且android也没有收到消息。我将android中的rabbitmq与我电脑的ip地址连接起来

问题出在这个

mModel.exchangeDeclare（mExchange，MyExchangeType，true）;

将其更改为

mModel.exchangeDeclare（mExchange，MyExchangeType）（不是被动交换）; ref https://groups.google.com/forum/#!topic/rabbitmq-discuss/hCtGUefIcRg

然后从ruby代码中删除了exchange.delete（因为删除了交换，你只会收到一条消息）

android没有从rabbitmq服务器接收来自ruby-amqp的消息的消息
