amqp-worker 是一个基于 Python 的多线程 RabbitMQ 消费框架。它可以让你在消费消息时更加高效和稳定。
|
|
|
|
|
|
|
|
|
|
## 功能特点
|
|
|
|
|
|
|
|
|
|
- 批量消费:按批处理消息,提高消费效率。
|
|
|
|
|
- 自动重连:当 RabbitMQ 服务断开连接时,amqp-worker 会自动重连,保证消费不中断。
|
|
|
|
|
- 自定义消费模式:消费函数中自由决定使用多线程和协程。
|
|
|
|
|
- 可配置的消息确认方式:支持自动确认和手动确认两种确认方式,根据你的消费需求进行配置。
|
|
|
|
|
- 可配置的异常处理:支持全局配置消息异常的消费模式,重入队列、重新插入、消费消息。
|
|
|

|
## 安装方式
|
|
|
|
|
|
|
|
|
|
你可以使用 pip 工具来安装 amqp-worker:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
pip install amqp-worker
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 使用方法
|
|
|
|
|
|
|
|
|
|
首先,你需要在你的 Python 代码中引入 amqp_worker 模块:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from amqpworker.app import App
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
然后,你需要实例化一个 App 对象,而App对象依赖AMQPConnection对象:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from amqpworker.connections import AMQPConnection
|
|
|
|
|
amqp_conn = AMQPConnection(hostname='127.0.0.1', username='guest', password='guest', port=5672)
|
|
|
|
|
|
|
|
|
|
app = App(connections=[amqp_conn])
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
接下来,你需要定义消费函数:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
@app.amqp.consume(
|
|
|
|
|
['test'],
|
|
|
|
|
options=AMQPRouteOptions(bulk_size=1024 * 8, bulk_flush_interval=2)
|
|
|
|
|
)
|
|
|
|
|
def _handler(msgs: List[RabbitMQMessage]):
|
|
|
|
|
print(f"Recv {len(msgs)} {datetime.now().isoformat()}")
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
上面的代码中我们给消费函数一个装饰器,给出了消费的队列,每批消费的数量,值得注意的是,消费函数的参数类型为`List[RabbitMQMessage]`
|
|
|
|
|
|
|
|
|
|
最后,只需要调用 `run` 方法即可开始消费:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
app.run()
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 示例代码
|
|
|
|
|
|
|
|
|
|
下面是一个简单的示例代码,它会消费名为 `test` 的队列中的消息:
|
|
|
|
|
|
|
|
|
|
```python
|
|
|
|
|
from datetime import datetime
|
|
|
|
|
from typing import List
|
|
|
|
|
|
|
|
|
|
from amqpworker.app import App
|
|
|
|
|
from amqpworker.connections import AMQPConnection
|
|
|
|
|
from amqpworker.rabbitmq import RabbitMQMessage
|
|
|
|
|
from amqpworker.routes import AMQPRouteOptions
|
|
|
|
|
|
|
|
|
|
amqp_conn = AMQPConnection(hostname='127.0.0.1', username='guest', password='guest', port=5672)
|
|
|
|
|
app = App(connections=[amqp_conn])
|
|
|
|
|
|
|
|
|
|
@app.amqp.consume(
|
|
|
|
|
['test'],
|
|
|
|
|
options=AMQPRouteOptions(bulk_size=1024 * 8, bulk_flush_interval=2)
|
|
|
|
|
)
|
|
|
|
|
def _handler(msgs: List[RabbitMQMessage]):
|
|
|
|
|
print(f"Recv {len(msgs)} {datetime.now().isoformat()}")
|
|
|
|
|
|
|
|
|
|
app.run()
|
|
|
|
|
|
|
|
|
|
```
