我正在尝试通过 python 将消息发布到 kafka 主题并收到错误消息。我可以通过 CLI 连接和发布。希望得到一些指导。我已经用谷歌搜索并阅读了文档。谢谢！！

成功的 CLI 命令：

 kafka-console-producer --broker-list 
 123.45.67.891:1234,123.45.67.892:1234,123.45.67.893:1234 -- 
 producer.config C:\Users\fake_user\Kafka\client-ssl.properties --topic FakeTopic

 Contents of client-ssl.properties:
   security.protocol = SSL
   ssl.truststore.location = C:/Users/fake_user/Kafka/kafka-truststore
   ssl.truststore.password = fakepass

代码：

from kafka import KafkaProducer

  producer = KafkaProducer(bootstrap_servers=['123.45.67.891:1234', '123.45.67.892:1234', '123.45.67.893:1234'],
                           security_protocol='SSL',
                           ssl_certfile=r'C:\Users\fake_user\Kafka\kafka-truststore',
                           ssl_password='fakepass')

  producer.send('FakeTopic', value='python_test', key='test')

结果错误：

看看这个链接。

对于几乎所有由 Java 运行的程序，您都必须将 SSL 证书添加到 JVM 密钥库中。

我发现默认情况下，python-kafka 库将 ssl_cafile 属性设置为 None。将其设置为默认操作系统（Linux 上的 /etc/pki/tls/cert.pem）允许我连接到 kafka 代理。
