现象：生产者不发送消息也不给出错误，服务器上看不到消息积累
from kafka import KafkaConsumer
# 生产者
server_list = ["10.15.13.87:9090","10.15.13.88:9090"]
producer = KafkaProducer(bootstrap_servers=server_list)
msg = "http://www.baidu.com"
bmsg = bytes(str(msg).encode('utf-8'))
producer.send('topicurl',bmsg)
解决方法：
from kafka import KafkaConsumer
# 生产者
server_list = ["10.15.13.87:9090","10.15.13.88:9090"]
producer = KafkaProducer(bootstrap_servers=server_list)
msg = "http://www.baidu.com"
bmsg = bytes(str(msg).encode('utf-8'))
producer.send('topicurl',bmsg)
#添加下面两行代码即可
producer.flush()
producer.close()
先挖坑，原因分析，后续补上
