python 连接kafka异常

异常如下：

连接信息：

from kafka import KafkaProducer
producer = KafkaProducer(bootstrap_servers=['localhost:9092'])

解决办法：
只需将security_protocol="SSL" KafkaProducer security_protocol="SSL"添加到KafkaProducer即可解决此KafkaProducer ，如下所示：

from kafka import KafkaProducer
producer = KafkaProducer(security_protocol="SSL", bootstrap_servers=['localhost:9092'])
