How to get the access token by invoking NIFI Rest API

[#1]

I am invoking an API command (nifi-api/access/token) to get the access token. But i am getting blank output. we have LDAP configured in NiFi Cluster and i am able to login to NiFi UI using my credentials. I have started exploring the NiFi rest API for the first time. Any help would be appreciated !!

Thank you in Advance,

Here is the format of the command you need to get a token:

curl 'https://nifi-host:port/nifi-api/access/token' -H 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8' --data 'username=ldap-username&password=ldap-password' --compressed —insecure

Then add the following to all of your subsequent curl commands

-H 'Authorization: Bearer token-returned’

Here is the command you need, just fill in your appropriate values:

curl 'https://nifi-host:port/nifi-api/access/token' -H 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8' --data 'username=ldap-username&password=ldap-password' --compressed —insecure

And there you go, this will return the token you need.

The subsequent curl commands will need the token returned as part of the command:

-H 'Authorization: Bearer token-returned'

Thank you @Wynner, I am able to get the access token using your code. can you please recommend the Rest API documentation which i should follow.

The Rest API documentation will be found at the URL: https://nifi-host:port/nifi-docs/rest-api

Just replace the the nifi-host and port values with your information.
