Not able to update ParameterContent using Nifi REST API

mohdriyaz — Tue, 12 Mar 2024 07:22:35 GMT

Hello All,

I am using Nifi 2.0

I want to update existing Parameter Context using Nifi API. For that , following API is used

https://localhost:8443/nifi-api/parameter-contexts/2ddc0cea-018e-1000-3852-3611d730f705/update-requests

Where "2ddc0cea-018e-1000-3852-3611d730f705" is the Id of parameter context.

Issue :

I tried to update the ParameterContext using

https://localhost:8443/nifi-api/parameter-contexts/2ddc0cea-018e-1000-3852-3611d730f705/update-requests

but its throwing 403 error .

I updated the Request with token (Bearer) but still getting the same error.

Any Pointers..??

Thanks,

Riyaz

403 : Client is not authorized to make this request.

This means you are Authenticated and since you have a valid token but you are not authorized to do this action.

to double-check if your user is Authorized, check if you can do the same action directly from NiFi UI ?

Thank you

@ckumar

Yes , i am able to do the changes via Nifi UI.

Note :

I have created the user user using following command :

nifi.cmd set-single-user-credentials username password

I would further interested check nifi-user.log to see the forbidden events when you see 403 error

I am able to solve the problem

Access token Rest API generates two token (check under cookies) - Secure-Request-Token and other is Secure-Authorization-Bearer token.

While calling any of the other API (like creating Parameter Context or updating Parameter context) - in Headers provide one more header "Request-Token" with the value of _secure-Request-Token (From cookies).
