flask-rabbitmq is a frame that simplifies python to operate rabbitmq and can be combined with Flask very well. So you don't need to think about the underlying operations
This project has been commited to Pypi, can be installed by pip:
$ pip install flask-rabbitmq- Start following Flask app, no consideration about the process blocking
- Configure by
config.py - Support declaring queue by decorator or register class
Firstly instantiate RabbitMQ and Queue object in app/__init__.py then import demo module:
from example.app import app
from flask_rabbitmq import Queue
from flask_rabbitmq import RabbitMQ
queue = Queue()
rpc = RabbitMQ(app, queue)
from example.app import demoCreate demo package and __init__.pyfile in appdirectory. Now you can declare queue and consumer in __init__.pyfile:
from example.app import rpc,queue
from flask_rabbitmq import ExchangeType
# declare the queue of defaulted exchange by decorator
@queue(queue_name='helloc')
def helloc_callback(ch, method, props, body):
print(body)
# declare the queue of topic exchange, flask-rabbitmq will bind automatically by key
@queue(queue_name='hello-topic', type=ExchangeType.TOPIC, exchange_name='hello-exchange',
routing_key='hello-key')
def hellp_topic_callback(ch, method, props, body):
print(body)
rpc.run()Email：
