这是我的消费者配置。我正在使用ssl进行身份验证。

consumer = KafkaConsumer(config['kafka_topic'],
                         bootstrap_servers=config['kafka_brokers'],
                         auto_offset_reset='earliest',
                         enable_auto_commit=True,
                         group_id='recognition',
                         ssl_cafile='../kafka.ca.pem',
                         security_protocol="SSL", sasl_mechanism='PLAIN',
                         sasl_plain_password=config['kafka_password'],
                         sasl_plain_username=config['kafka_username'],
                         api_version=(0, 10, 1),
                         value_deserializer=lambda x: loads(x.decode('utf-8')))

错误：
