如何将Python使用者连接到AWS MSK

我正在尝试将python使用者连接到AWS MSK集群。我该怎么做

运行AWS MSK群集 我正在尝试使用python和kafka python使用来自MSK集群的消息

我犯了一个错误

使用kafka python：

from kafka import KafkaConsumer

if __name__ == '__main__':
    topic_name = 'example-topic'

    consumer = KafkaConsumer(topic_name, auto_offset_reset='earliest',
                             bootstrap_servers=['kafka2:9092'], api_version=(0, 10), consumer_timeout_ms=1000)
    for msg in consumer:
        print(msg.value)

    if consumer is not None:
        consumer.close()

你试过什么？你被困在哪里？您在搜索引擎中搜索过“Python Kafka”吗？目前，我在EC2中运行Kafka，并让Python消费者收听多个主题和处理。但是我需要运行AWS MSK集群并连接到它，所以将Python代码中的Kafka连接地址更改为MSK集群地址。如果这不起作用，请在问题中添加更多信息。这不起作用，这就是问题出现的原因…如果它不起作用，请在问题中提供错误消息。这可能根本不是Python的问题，而是AWS网络配置的问题，所以您也需要提供这些信息

from time import sleep

from kafka import KafkaProducer

# publish messages on topic
def publish_message(producer_instance, topic_name, key, value):
    try:
        key_bytes = bytes(key, encoding='utf-8')
        value_bytes = bytes(value, encoding='utf-8')
        producer_instance.send(topic_name, key=key_bytes, value=value_bytes)
        producer_instance.flush()
        print('Message ' + key + ' published successfully.')
    except Exception as ex:
        print('Exception in publishing message')
        print(str(ex))
