生产者：

import time,json
from kafka import KafkaProducer
import random
producer = KafkaProducer(bootstrap_servers=':9092,10.9:9092,10.180:9092',
                         value_serializer=lambda m: json.dumps(m).encode('utf-8'))
            

dlp_log =[
{
   "AccidentId ": "11111-3ce5"
},
{
   "AccidentId ": "22222-3ce5"
}
]
i=1
while i >0:
   
    data = dlp_log[random.randint(0,1)]
    print("i:",data)
    producer.send(topic="filterAnalysisResultIncident",value=data)
    time.sleep(2)
producer.flush()
producer.close()

消费者：

from kafka import KafkaConsumer
import json
consumer = KafkaConsumer('filcident', group_id='f_consumers1',
                         bootstrap_servers=['10.1:9092',
                                            '10.1:9092',
                                            '10.19:9092'],
                         value_deserializer=lambda m: json.loads(m.decode('utf-8')),
                         enable_auto_commit=False,
                         auto_offset_reset="latest")
try:
    for msg in consumer:
        try:
            print("value:",type(msg.value),msg.value)
            #print("%s:%d:%d: key=%s value=%s" % (msg.topic, msg.partition, msg.offset, msg.key, msg.value))
        except Exception as e:
            print("msg.value error:",e)
except KeyboardInterrupt as e:
    print("KeyboardInterrupt:",e)
