python flask简单使用redis

1. 创建app时初始化 

from flask_redis_sentinel import SentinelExtension


redis_sentinel = SentinelExtension()
redis_client = redis_sentinel.master_for('mymaster')


def create_app(conf_file):
    ... ...
    redis_sentinel.init_app(app)
    ... ...

2. 初始化app时加载config 

class Config(object):
    # redis requirepass：123456
    # redis sentinel：192.168.0.3:26379,192.168.0.4:26379,192.168.0.5:26379
    REDIS_URL = 'redis+sentinel://:[email protected]:26379,192.168.0.4:26379,192.168.0.5:26379/mymaster/0'

3. 定义路由，引入redis client并使用

from demo import redis_sentinel, redis_client, logger
from demo.api import api


@api.route('/api/redis/test', methods=['GET'])
def redis_test():
    master_info = redis_sentinel.sentinel.discover_master('mymaster')
    if master_info:
        master_ip, port = master_info
        logger.info('master ip: %s' % master_ip)
        logger.info('master port: %s' % port)

    slave_info = redis_sentinel.sentinel.discover_slaves('mymaster')
    if slave_info:
        slave_ip, port = slave_info
        logger.info('slave ip: %s' % slave_ip)
        logger.info('slave port: %s' % port)

    redis_client.set('name', 'jalen')
    name = redis_client.get('name')
    logger.info('name: %s' % name)
    return 200
