Python 整个会话中与数据库的单异步连接

如何在每次不创建新连接的情况下将数据插入数据库

async def insertFibo(message: DeliveredMessage):
    response = RabbitBody.decode(message.body)
    conn = await asyncpg.connect(DATABASE_URL)
    await conn.execute('''INSERT INTO fibonacci(number) VALUES($1)''', response.fibo)

    await message.channel.basic_ack(
        message.delivery.delivery_tag
    )

async def consume_rabbitmq():
    ...
    await channel.basic_consume(declare.queue, insertFibo)

if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    loop.run_until_complete(consume_rabbitmq())
    loop.run_forever()

你可以用a来做这个。
