I went through this tutorial on KONG https://getkong.org/plugins/jwt/
I have an understanding of JWT and authorization concepts. I have prototyped JWT with Spring Boot where I could put my own key value like this {"authorizations":"role_admin, role_user"}.
It is easy to do that in Spring Boot but I am not able to find information on how to do this with KONG. Anyone has any info about it?
Kong community edition can handle only the authentication process, (give or deny access to a customer).
Authorization process (what a given customer can do in your application) is handled by your application or by https://getkong.org/plugins/ee-oauth2-introspection/ oauth2 introspection plugin which is enterprise edition only
you can write your own authorization server based on X-Consumer-Username request header if user passed authentication or original token header proxied by kong
hope helps
The kong jwt plugin does not support sending custom payload parameters to the upstream api. It does however seem like you can use this plugin (I have not tested it):
https://github.com/wshirey/kong-plugin-jwt-claims-headers
Update:
If you set Kong to forward all headers you'll get the raw Authorization header with the jwt token. So you could base64 decode the jwt token and pull out the claims/payload parameters you need manually in your service.
