I have been able to run my rest calls and get json data returned. I do
have a process for creating Json objects from those responses, but I see
there is the nifi API has object classes for successful returns.
For example, the /controller/about call returns a JSON with two entries
(revision and about) and according to the Rest API doc it could also be
an AboutEntity that has two properties with the same respective names.
But when I look at the About entity, it doesn't have a constructor to
use a JSON string to set the property values and create an instance of
the entity.
Is there a recommended approach for getting the response as the
respective Entity object for the rest call?
Also, I've tried some attempts to test Nifi's persistence when a data
flow is active. But I think the data flow I've created is too small or
simple as by the time I've disabled power the to mission, the data flow
has successfully run it's course. Are there any recommendations for ways
to test what happens to data within a data flow when nifi is suddenly
terminated?
I know there are four repositories in use, does the data in a data flow
get stored in any of these repositories when transitioning between
processors within a data flow? Does Nifi continue where it left off when
possible?

John,
The API lives at /nifi-api, so the address you are looking for would
be http://localhost:8080/nifi-api/controller/about
Please let us know if you have any additional questions or stumbling
blocks. Thanks!

Greetings all,
I have started looking into Apache Nifi. I was interested in using
the Rest API and after I started my instance of Nifi, I wanted to
test it.
My Nifi is located at localhost:8080/nifi. I am using Rest Web
Service Client on Chrome
I set the method to GET and the URL to
http://localhost:8080/nifi/controller/about
I think this is a good rest call to use since the Authorization is
Ready Only and the data shouldn't be anything critical.
I get the the following response:
404, Not Found
Date: Wed, 02 Sep 2015 15:08:44 GMT
Cache-Control: must-revalidate,no-cache,no-store,
must-revalidate,no-cache,no-store
X-UA-Compatible: IE=edge
Server: Jetty(9.2.11.v20150529)
Content-Length: 305
Content-Type: text/html; charset=ISO-8859-1
*Time taken*(in milliseconds): 52
Mind you, I don't have any users entered into Nifi's user list.
This is currently just a barebones Nifi instance.
I don't know why the response contains IE=edge as I do not have
that software on my Mac.
Is the path I entered for URL incorrect? Then I set the URL to
http://localhost:8080/controller/about
and it returned a response code of 200, however in the Raw
Response I got the following message about mistyping and
recommending I add "/nifi" to the path:
<!DOCTYPE html>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
