python-kafka 不支持 SASL_PLAINTEXT绊袋， SCRAM-SHA-256娇昙，所以選擇confluent_kafka
- 客戶端
from confluent_kafka import Consumer, KafkaError
topic_name = 'test-topic'
KAFKA_BROKER_SERVERS = "127.0.0.1:9092"
consumer = Consumer({
'bootstrap.servers': KAFKA_BROKER_SERVERS,
'group.id': 'omega-self-approve',
'auto.offset.reset': 'earliest',
'security.protocol': 'SASL_PLAINTEXT',
'sasl.mechanisms': 'SCRAM-SHA-256',
'sasl.username': 'admin',
'sasl.password': 'admin',
})
consumer.subscribe([topic_name])
while True:
msg = consumer.poll(1.0)
if msg is None:
continue
if msg.error():
print("Consumer error: {}".format(msg.error()))
continue
print('Received message: {}'.format(msg.value().decode('utf-8')))
consumer.close()

else:

producer = Producer(**conf)
for i in range(1):
data = {"test": 1, "test2": 2}
producer.produce(topic_name, (json.dumps(data)).encode(), callback=delivery_report)
producer.flush()
