无法在 Windows 11 中使用 SpoolDirCsvSourceConnector 创建用于 CSV 到 Kafka 的 kafka 连接源和接收器连接器

问题描述 投票：0回答：1

我想使用此 repo 将我的 testdata.csv 上传到 Kafka 主题。现在，curl 命令无法创建自定义连接器 

curl -i -X PUT -H "Accept:application/json" -H  "Content-Type:application/json" http://localhost:8083/connectors/source-csv-spooldir-00/config  -d @sample.json

这是我的 docker compose

version: '2'

  zookeeper:
    image: confluentinc/cp-zookeeper:6.2.0
    container_name: zookeeper
    environment:
      ZOOKEEPER_CLIENT_PORT: 2181

    # An important note about accessing Kafka from clients on other machines:
    # -----------------------------------------------------------------------
    #
    # The config used here exposes port 9092 for _external_ connections to the broker
    # i.e. those from _outside_ the docker network. This could be from the host machine
    # running docker, or maybe further afield if you've got a more complicated setup.
    # If the latter is true, you will need to change the value 'localhost' in
    # KAFKA_ADVERTISED_LISTENERS to one that is resolvable to the docker host from those
    # remote clients
    #
    # For connections _internal_ to the docker network, such as from other services
    # and components, use broker:29092.

和输出

or

{"error_code":400,"message":"Connector configuration is invalid and contains the following 2 error(s):\nInvalid value File 'C:/Users/vinee/Downloads/kafka-connect/demo-scene-master/kafka-connect-zero-to-hero/data/unprocessed' is not an absolute path. for configuration input.path\nInvalid value File 'C:/Users/vinee/Downloads/kafka-connect/demo-scene-master/kafka-connect-zero-to-hero/data/error' is not an absolute path. for configuration error.path\nYou can also find the above list of errors at the endpoint `/connector-plugins/{connectorType}/config/validate`"}

我尝试更改我想到的所有内容，以获取“input.path”、“output.path”和“error.path”的有效值，但输出不会改变，除了无效值后面引号中的内容

C:\Users\vinee\Downloads\kafka-connect\demo-scene-master\kafka-connect-zero-to-hero\data\unprocessed 
C://Users//vinee//Downloads//kafka-connect//demo-scene-master//kafka-connect-zero-to-hero//data//unprocessed

/c:/Users/vinee/Downloads/kafka-connect/demo-scene-master/kafka-connect-zero-to-hero/data/unprocessed
.\data\unprocessed

这是数据文件夹

在 docker-compose.yaml 中将 

PWD
更改为 
C://Users//vinee//Downloads//kafka-connect//demo-scene-master//kafka-connect-zero-to-hero
并将 
C://Users//vinee//Downloads//kafka-connect//demo-scene-master//kafka-connect-zero-to-hero//data//unprocessed
更改为 
/data/unprocessed
有效，我得到了状态 201。感谢 @OneCricketeer 的帮助。
