我是debezium的新手，正在尝试将我的kafka连接器连接到我的wamp服务器上已经存在的mysql数据库。
我根据教程文档启动了zookeeper和kafka，然后启动了kafka连接器。在我的postman中，我将以下json发送到我的kafka连接器，但我不断收到错误的请求响应。
启动Zookeper

docker run -it --rm --name zookeeper -p 2181:2181 -p 2888:2888 -p 3888:3888 debezium/zookeeper:0.7

开始Kafka

docker run -it --rm --name kafka -p 9092:9092 --link zookeeper:zookeeper debezium/kafka:0.7

启动Kafka连接器

docker run -it --rm --name connect -p 8083:8083 -e GROUP_ID=1 -e CONFIG_STORAGE_TOPIC=my_connect_configs -e OFFSET_STORAGE_TOPIC=my_connect_offsets --link zookeeper:zookeeper --link kafka:kafka debezium/connect:0.7

我用 Postman 发了以下邮件

{ "name": "shopcentra-connector", "config": { "connector.class": "io.debezium.connector.mysql.MySqlConnector", "tasks.max": "1", "database.hostname": "127.0.0.1", "database.port": "3306", "database.user": "root", "database.password": "root", "database.server.id": "5444", "database.server.name": "shopcentra", "database.whitelist": "shopcentra", "database.history.kafka.bootstrap.servers": "kafka:9092", "database.history.kafka.topic": "dbhistory.shopcentra", "include.schema.changes": "true" } }
