gRPC ServerInterceptor with Armeria

I am using Armeria with gRPC/java and I'm looking to decorate one of the services with an AuthService like this https://sultanov.dev/blog/securing-java-grpc-services-with-jwt-based-authentication/. I want to access the gRPC request header, do some validation, and if validated, write something in the context object and proceed.

I am having some trouble finding documentation for how to interact with the context object correctly. Can someone help point me in the right direction? Thanks!

You can use an Armeria decorator to intercept the call and validate it: https://armeria.dev/docs/server-decorator#extending-simpledecoratinghttpservice-and-simpledecoratingrpcservice

It's beneficial when you need to make another asynchronous call in the intercepting logic because it's not easy to do that with a gRPC interceptor.

You can write something to RequestContext in the decorator. https://armeria.dev/docs/advanced-custom-attributes#requestcontext-custom-attributes You can retrieve it in your service via RequestContext.current() later.

Check this out. This shows how to get the JWT from the metadata (request header) and set some value into the context accordingly.
