Is it possible to get the ID of a processor/connector in apache NiFi using the rest API?

I'm exploring the rest API functionalities provided by NiFi. I have a question: can we get the ID of a component, be it a processor, processor group, controller services,etc., using NiFi-API by querying the component's name?

I tried http://localhost:8080/nifi-api/flow/search-results?q=sample I have a processor group named sample in my NiFi Flow.

enter image description here

And I have a GetFile processor named sample get file and I queried this: http://localhost:8080/nifi-api/controller/search-results/q='sample get file'. None of them seem to work. The NiFi-API documentation wasn't quite helpful in these aspects. So guide me how to achieve this.

De Santa,

If you wants to get id of the processor u have to know process group ID of the processor.

Here i have simple example in which gets the id of the processors in root.

http://localhost:8080/nifi-api/controller/process-groups/root/processors

Above code works in nifi-0.6.1.

EDIT1

In NiFi-1.1.1

You have to use below rest api to collect processors

Process group id:515eeb84-646b-4b33-eaf7-2028420a9fcb

http://localhost:8089/nifi-api/process-groups/515eeb84-646b-4b33-eaf7-2028420a9fcb/processors

Above API collects number of processors in mentioned Process group id.

[OR]

Process group id:root

http://localhost:8089/nifi-api/process-groups/root/processors

It collects the number of available processors in Root Canvas.

So if you know ID of the process group in which processor besides then easy to get processor ID.
