NiFi rest api creating parameter context

MeAndB — Sun, 09 Jan 2022 06:06:26 GMT

Hi,

I noticed that in NiFi rest api documentation for version 1.9.0 the parameter context endpoints have been removed, even though they existed in version 1.15.2

Furthermore, I am using NiFi version 1.13.2 and I can see that in my browser's debugging tools, in the network tab, whenever I create a parameter context, a post request is sent to

http://localhost:8080/nifi-api/parameter-contexts:

and the following payload is being sent :

{ "component": { "name": "aaaaaaaaaaa", "description": "aaaaaaaaaaaaaaaa", "parameters": [] }, "revision": { "clientId": "3d3697c2-017e-1000-0610-31b28073cf9b", "version": 0 } }

The parameter context is successfully created. However when I attempt to send a post request from an external API or even hit the previously mentioned endpoint through the browser using the same payload, I get:

HTTP 405 Method Not Allowed

My questions are:

1. Is anyone aware whether these endpoints have been removed/restricted intentionally?

2. If they are not remove/restricted, has anyone been able to successfully send a post request and create a parameter context through NiFi's rest api?

Hi,

I figured it out. It had to do with me not serialising the data to json properly before passing it as json and also I should have used the following for the header:

headers={"Content-type": "application/json", "Accept": "application/json"}

Also, this means, that even though the parameter context endpoints are not listed in version 1.9.0., they are still available.
