上一篇文章是生产数据：python向kafka发送json数据_grfstc的博客-CSDN博客

1.安装kafka支持库

pip install kafka-python

2.创建python文件

import time
from kafka import KafkaConsumer

consumer = KafkaConsumer(
	'FaultRecordLog',
	group_id='test_id',
	bootstrap_servers=['192.168.1.214:9092'],    # 要发送的kafka主题
	auto_offset_reset='earliest',  # 有两个参数值，earliest和latest，如果省略这个参数，那么默认就是latest
)
for msg in consumer:
	print(msg)
	print(f"topic = {msg.topic}")  # topic default is string
	print(f"partition = {msg.partition}")
	print(f"value = {msg.value.decode()}")  # bytes to string
	print(f"timestamp = {msg.timestamp}")
	print("time = ", time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(msg.timestamp / 1000)))

3.运行该python文件

注意：

该python文件会持续消费kafka数据，如果要停止消费，需手动退出程序。

或者可以设置达到特定偏移量退出for循环来停止消费：

lastOffset = 42
for msg in consumer:
	print(msg)
	print(f"topic = {msg.topic}")  # topic default is string
	print(f"partition = {msg.partition}")
	print(f"value = {msg.value.decode()}")  # bytes to string
	print(f"timestamp = {msg.timestamp}")
	print("time = ", time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(msg.timestamp / 1000)))
	if msg.offset == lastOffset - 1:
		break

 运行效果：
