如何在Redis中维护之前删除的密钥列表？

import redis

# 连接到Redis
r = redis.Redis(host='localhost', port=6379, db=0)

# 删除密钥并记录到列表中
def delete_key_and_log(key):
    r.lpush('deleted_keys', key)
    r.delete(key)

# 获取删除的密钥列表
def get_deleted_keys():
    return r.lrange('deleted_keys', 0, -1)

# 示例
delete_key_and_log('mykey1')
delete_key_and_log('mykey2')
print(get_deleted_keys())  # 输出: ['mykey2', 'mykey1']

import redis

# 连接到Redis
r = redis.Redis(host='localhost', port=6379, db=0)

# 启用键空间通知
r.config_set('notify-keyspace-events', 'Kl')

# 订阅删除事件
pubsub = r.pubsub()
pubsub.psubscribe('__keyevent@0__:del')

# 处理删除事件
for message in pubsub.listen():
    if message['type'] == 'pmessage':
        print(f'Key deleted: {message["data"].decode()}')

r.expire('deleted_keys', 86400)  # 设置过期时间为24小时
