Pika是一个纯Python实现的AMQP 0-9-1协议，它尝试与底层网络支持库之间保持独立。支持多种适配器，如TwistedConnection（适用于Twisted异步包）、TornadoConnection（适用于Tornado IO循环）等。

• Currently supports Python 2.6 and Python 2.7 only. 3.2+ support planned.
• Since threads aren't appropriate to every situation, it doesn't require threads. It takes care not to forbid them, either. The same goes for greenlets, callbacks, continuations and generators. It is not necessarily thread-safe however, and your milage will vary.
• People may be using direct sockets, asyncore, plain old select(), or any of the wide variety of ways of getting network events to and from a python application. Pika tries to stay compatible with all of these, and to make adapting it to a new environment as simple as possible.

Example

Here is the most simple example of use, sending a message with the BlockingConnection adapter:

import pika  connection = pika.BlockingConnection()  channel = connection.channel()  channel.basic_publish(exchange='example',                        routing_key='test',                        body='Test Message')  connection.close()

And an example of writing a blocking consumer:

import pika  connection = pika.BlockingConnection()  channel = connection.channel()    for method_frame, properties, body in channel.consume('test'):        # Display the message parts and ack the message      print method_frame, properties, body      channel.basic_ack(method_frame.delivery_tag)        # Escape out of the loop after 10 messages      if method_frame.delivery_tag == 10:          break    # Cancel the consumer and return any pending messages  requeued_messages = channel.cancel()  print 'Requeued %i messages' % requeued_messages  connection.close()
