Apache nifi Nifi通过RESTAPI创建控制器服务

我正在尝试从nifi rest api创建DbcpController服务。我也得到了正确的响应，但当我转到UI时，控制器服务不可见

curl -i -X POST -H 'Content-Type:application/json'

请求中是否有我丢失的任何参数。

我不确定“当我转到UI时，控制器服务不可见”是什么意思

当您转到Apache NiFi UI并单击控制器设置>控制器服务时，您看不到列出的任何控制器服务—是否可能刷新浏览器并清除缓存？我不认为这是你的问题

列出了控制器服务，但它不可在处理器中使用——这是因为CS被添加到全局级别，这意味着它可用于报告要引用的任务，但不可用于画布上的处理器。您需要在JSON中的

ControllerServiceDTO

对象中提供一个

parentGroupId

，以便CS可用于画布上的组件（在该父组中）。您的URL如下所示：

/nifi api/流程组/a0f3dfb7-0165-1000-8310-4fb72628adaa/控制器服务

我认为这是你的问题

控制器服务可在处理器中使用，但未启用——这是因为您正在将CS的状态设置为禁用。您可以发出一个额外的命令来启用CS，或者最初将状态设置为启用

如果在画布上单击鼠标右键并选择“配置”，您将获得所属流程组的对话框（默认情况下在根级别称为“NiFi流”），并且有一个“控制器服务”选项卡，其中将列出您创建的CS

您可以始终在UI中执行这些操作，并使用浏览器的“开发人员工具”面板来监视请求——NiFi的UI是REST API的使用者，因此，在那里执行的任何活动都可以单独使用API来完成

示例：

嗨，谢谢@Andy我错过了processorGroup。我现在能看到了。
