直接通过 kafka 命令行是可以消费的，但通过 python 消费时，一直消费不到，进程也不超时

import time
from kafka import KafkaConsumer

topic1 = 'additional_order'
host = '192.168.14.55:9092'


consume = KafkaConsumer(topic, group_id="group1", 
                              bootstrap_servers=host, auto_offset_reset='latest',
                              security_protocol='SASL_PLAINTEXT',
                              sasl_mechanism='PLAIN',
                              sasl_plain_username='admin',
                              sasl_plain_password='$%foper!@#$',
                              api_version=(0, 10)
                              )


while True:
    count += 1
    if time.time() - start_time > 1 * 60:
        print('超时,退出')
        break
    msg = consume.poll(1000, 1)  # 看上去，进程是一直等候在这里
    print(count)
