使用AIOKafka客户端连接到融合云

Question

我正在尝试使用AIOKafka{}repo athttps://github.com/aio-libs/aiokafka/blob/master/examples/ssl_consume_produce.py中AIOKafka{}示例的修改版本连接到我的Confluent CloudKafka集群。我已使用我认为正确的参数配置了我的AIOKafkaConsumer和AIOKafkaProducer，但出现以下运行时错误：

/Users/galen/opt/anaconda3/envs/ds/bin/python /Volumes/ThunderBlade/github/kafka/aiokafka/examples/ssl_consume_produce.py
Traceback (most recent call last):

我对代码的修改版本是：

import asyncio
from ssl import create_default_context, Purpose
from aiokafka import AIOKafkaProducer, AIOKafkaConsumer
from kafka.common import TopicPartition

import ccloud_lib

ssl_context = create_default_context(Purpose.SERVER_AUTH, cafile='cacert.pem')
conf = ccloud_lib.read_ccloud_config('kafka_config.conf')

async def produce_and_consume(loop):
    # Produce
    producer = AIOKafkaProducer(
        bootstrap_servers=conf['bootstrap.servers'],
        loop = loop,
        security_protocol='SASL_SSL',
        ssl_context=ssl_context,
        sasl_mechanism='PLAIN',
        sasl_plain_password=conf['sasl.password'],
        sasl_plain_username=conf['sasl.username']
    )

    await producer.start()
    try:
        msg = await producer.send_and_wait(
            'my_topic', b"Super Message", partition=0)
    finally:
        await producer.stop()

    consumer = AIOKafkaConsumer(
        bootstrap_servers=conf['bootstrap.servers'],
        loop=loop,
        ssl_context=ssl_context,
        security_protocol='SASL_SSL',
        sasl_mechanism='PLAIN',
        sasl_plain_password=conf['sasl.password'],
        sasl_plain_username=conf['sasl.username']
    )
    await consumer.start()
    try:
        consumer.seek(TopicPartition('my_topic', 0), msg.offset)
        fetch_msg = await consumer.getone()
    finally:
        await consumer.stop()

    print("Success", msg, fetch_msg)

if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    task = loop.create_task(produce_and_consume(loop))
    try:
        loop.run_until_complete(task)
    finally:
        loop.run_until_complete(asyncio.sleep(0, loop=loop))
        task.cancel()
        try:
            loop.run_until_complete(task)
        except asyncio.CancelledError:
            pass

我的模糊配置conf如下所示：

bootstrap.servers=*****.us-central1.gcp.confluent.cloud:9092
ssl.endpoint.identification.algorithm=https
security.protocol=SASL_SSL
sasl.mechanism=PLAIN
sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username\="********************" password\="****************************************";
sasl.username=********************
sasl.password=********************************************************************************
basic.auth.credentials.source=USER_INFO
schema.registry.basic.auth.user.info=********************:********************
schema.registry.url=https://********************.us-central1.gcp.confluent.cloud

是否可以使用AIOKafka客户端连接到Confluent Cloud？我的配置是否有不正确的地方
