查找 NiFi 远程进程组通过其 Rest API 启用或禁用

Question

使用NiFi REST API，

1. 如何查找远程进程组是启用还是禁用？
2. NiFi中传输（RemoteProcessGroupDTO）和传输状态（RemoteProcessGroupStatusDTO）之间的区别？

端点：https://nifihost:8080/nifi-api/process-groups/{id}/remote-process-groups

Answer 1

1.如何查看远程进程组是启用还是禁用？

\n

您需要使用不同的端点来确定 RPG 是否启用

\n

https://nifihost:8080/nifi-api/remote-process-groups/{id}\n

\n

您可以解析 json 并检查组件对象中传输的值或状态对象中的 TransmissionStatus

\n

2.NiFi中的transmission（RemoteProcessGroupDTO）和transmissionStatus（RemoteProcessGroupStatusDTO）有什么区别？

\n

两者都显示 RPG 传输的状态是布尔值，transmissionStatus 可以有字符串值
