RabbitMQ 是一种常用的开源消息代理软件,也被称为消息队列或者消息中间件。它是一个由 Erlang 实现的高度可伸缩的、可重用的企业消息系统。它支持多种消息协议,例如 Advanced Message Queuing Protocol(AMQP),Simple Notification Service(SNS),Simple Queue Service(SQS)等。这些协议允许开发人员在不同的语言和平台之间进行通信,并且在分布式应用程序之间传递消息。
以下是 RabbitMQ 的一些常用特性[^1]:
1. 可靠的消息传输:RabbitMQ 确保了消息的传输和接收,即使在网络不可靠的情况下,也不会丢失消息。
2. 轻量级和高性能:RabbitMQ 是一个轻量级的消息中间件,它可以处理大量的消息,并且在同时保持高性能和低延迟。
3. 可管理性:RabbitMQ 提供了一个易于使用的 Web 界面,可以监控和管理消息队列,包括创建、删除、绑定和发布消息等操作。
4. 丰富的 API:RabbitMQ 支持多种编程语言和开发框架,包括 Java、Python、.NET、Ruby、PHP、Perl、Erlang 和 Go 等。
以下是在 Python 中使用 RabbitMQ 的一个例子[^2]:
安装 Python 客户端:
```shell
pip install pika
```
使用 Python 生产者向 RabbitMQ 发布消息:
```python
import pika
connection = pika.BlockingConnection(pika.ConnectionParameters('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()
```
使用 Python 消费者从 RabbitMQ 接收消息:
```python
import pika
connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
channel = connection.channel()
channel.queue_declare(queue='hello')
def callback(ch, method, properties, body):
print(" [x] Received %r" % body)
channel.basic_consume(queue='hello',
on_message_callback=callback,
auto_ack=True)
print(' [*] Waiting for messages. To exit press CTRL+C')
channel.start_consuming()
```
