Question

我正在尝试通过python发送数据（ input_data ），如下图所示。

[{
  "stateActionTraffic":"1, S1, 1, A1, 20, 0.65
                        1, S1, 2, A2, 20, 0.65
                        1, S1, 3, A3, 20, 0.65
                        2, S2, 1, A1, 25, 0.65
                        2, S2, 2, A2, 25, 0.65
                        2, S2, 3, A3, 25, 0.65"
   "messageType":"split",
   "Id":1232324334
}]

input_data 的基本上数据类型是列表

以下我尝试过的kafka代码是将python（3.x）发送到kafka：

import logging
from kafka.errors import KafkaError
logging.basicConfig(level=logging.INFO)
kafka_brokers=['kafka1-1-stagepf.stage-sin.real.com:9092']
producer = KafkaProducer(bootstrap_servers=kafka_brokers,value_serializer=lambda v: json.dumps(v).encode('utf-8'), api_version=(1,4,6))
producer.send('topic', input_data)
producer.flush()

但是在登录时，我看到在生成以下日志时根本没有发送数据：

因此，正如您从日志文件中看到的那样，没有将数据发送到kafka域的主题，在该日志文件中尝试建立连接然后断开连接。它说连接完成，但随后立即说已断开连接。不知道这里发生了什么。任何帮助将不胜感激。

Python Kafka生产者无法将json数据发送到cnosumer
