3/创建连接

curl -X POST 'http://localhost:8080/nifi-api/process-groups/fd6ba415-015b-1000-b8ee-13ea77e54502/connections' \
 -H 'Content-Type: application/json' \
 -H 'Accept: application/json' \
 --data-binary '{
    "revision": {
        "clientId": "439a9b14-015c-1000-5924-200a7fdaf626",
        "version": 0
    },
    "component": {
        "name": "",
        "source": {
            "id": "439b2f6c-015c-1000-6eb1-59309b64c5dd",
            "groupId": "fd6ba415-015b-1000-b8ee-13ea77e54502",
            "type": "PROCESSOR"
        },
        "destination": {
            "id": "439b565d-015c-1000-320b-5db5df870c12",
            "groupId": "fd6ba415-015b-1000-b8ee-13ea77e54502",
            "type": "PROCESSOR"
        },
        "selectedRelationships": ["success"],
        "flowFileExpiration": "0 sec",
        "backPressureDataSizeThreshold": "1 GB",
        "backPressureObjectThreshold": "10000",
        "bends": [],
        "prioritizers": []
    }
}' 

4/删除处理器(之前必须删除传入的连接)

4/ delete processor (you have to delete incoming connections before)

curl -X DELETE \
'http://localhost:8080/nifi-api/processors/439b565d-015c-1000-320b-5db5df870c12?version=2&clientId=439a9b14-015c-1000-5924-200a7fdaf626'
