rabbitmq中python和ruby通信

      前面一章已經介紹了rabbitmq在python中傳遞消息，那麼作爲比較強大的rabbitmq中間件，他如何實現在ruby上傳遞消息以及和python中間傳遞消息呢？

      1.安裝rabbtmq的服務器，（前一篇已經介紹過了）

      2. gem install bunny   --安裝bunny的gem包，這樣就可以在客戶端用ruby訪問了

      我們寫一個send.rb

   require "bunny"     --引入bunny

   conn = Bunny.new(:hostname => "localhost")
   conn.start                        --鏈接服務器

   ch = conn.create_channel          --創建通道
   

   q    = ch.queue("hello")         --創建隊列hello
   ch.default_exchange.publish("Hello World!", :routing_key => q.name)
   puts " [x] Sent 'Hello World!'"

conn.close

然後在寫一個 receive.rb

   require "bunny"

   conn = Bunny.new
   conn.start
   ch   = conn.create_channel
   q    = ch.queue("hello")

   puts " [*] Waiting for messages in #{q.name}. To exit press CTRL+C"
   q.subscribe(:block => true) do |delivery_info, properties, body|
      puts " [x] Received #{body}"

      # cancel the consumer to exit
      delivery_info.consumer.cancel
   end
 好了，運行下就好了！

$ ruby send.rb

" [x] Sent 'Hello World!'"

$ ruby receive.rb
 

”[x] Received Hello World!"

這是ruby和ruby之間通信，那麼我們在加入python的代碼

send.py

import pika

connection = pika.BlockingConnection(pika.ConnectionParameters(
        host='localhost'))
channel = connection.channel()

channel.queue_declare(queue='hello')

channel.basic_publish(exchange='',
                      routing_key='hello',
                      body='Hello World!')
print " [x] Sent 'Hello World!'"
connection.close()

我們在運行下
python send.py

" [x] Sent 'Hello World!'"

ruby receive.rb

" [x] Receive 'Hello World!'"
