基本概念理解

A producer a program that sends messages.

A queue is the name for a mailbox. 

A consumer is a program that mostly waits to receive messages.

The connection abstracts the socket connection, and takes care of protocol version negotiation and authentication and so on for us. 

A channel is where most of the API for getting things done resides.

An exchange receives messages from producers and pushes them to queues.

AMQP（Advanced Message Queuing Protocol） is an open standard application layer protocol for message-oriented middleware. 

RPC（Remote Procedure Call）is a pattern that run a function on a remote computer and wait for the result.

4.收消息前也需要声明队列，consumer优先启动时，需要明确从哪个队列消费

5.
