python&kafka集群取消息

Posted 2020-12-12 jxba

安装

pip3 install setuptools

pip3 install pykafka

pip3 install kafka-python

 

单台kafka

import sys
from kafka import KafkaConsumer
from kafka.structs import TopicPartition
consumer = KafkaConsumer(
    enable_auto_commit=False,
    bootstrap_servers=["xxx-xx-x-sh-yyy-Eyy.yd.com:1234"])
consumer.subscribe(topics=(‘indata_str_abcde_click_new‘))

if sys.getdefaultencoding() != ‘utf-8‘:
    reload(sys)
    sys.setdefaultencoding(‘utf-8‘)

for message in consumer:
    print ("%s:%d:%d: key=%s value=%s" % (message.topic, message.partition,
    message.offset, message.key,
    message.value.decode()))

kafka集群 

bootstrap_servers 参数使用‘‘,‘‘,‘‘隔开

import sys
from kafka import KafkaConsumer
from kafka.structs import TopicPartition
consumer = KafkaConsumer(
    enable_auto_commit=False,
    bootstrap_servers=["xxx-xx-x-sh-yyy-Eyy.yd.com:1234"，"xxx-xx-x-sh-yyy-Eyy.yd.com:1231"，"xxx-xx-x-sh-yyy-Eyy.yd.com:1232"])
consumer.subscribe(topics=(‘indata_str_abcde_click_new‘))

if sys.getdefaultencoding() != ‘utf-8‘:
    reload(sys)
    sys.setdefaultencoding(‘utf-8‘)

for message in consumer:
    print ("%s:%d:%d: key=%s value=%s" % (message.topic, message.partition,
    message.offset, message.key,
    message.value.decode()))

可成功拿到消息
