I'm guessing you are interested in doing this with Java (since I see "[grpc-java]" in the subject).
You can query the grpc ServiceDescriptor for its "schema descriptor". For proto-generated services, this will be a ProtoFileDescriptorSupplier, that provides access to the FileDescriptor, which in turn contains everything you're looking for. The slight trick is that the interceptor, with each call, only sees a MethodDescriptor for the method being invoked, which does not appear to have a reference back to its enclosing ServiceDescriptor. So you'd need to construct a "sidecar" map that allows access to the service descriptors from the interceptor(s). Here's a gist that demonstrates this: https://gist.github.com/jhump/e8f67087ec5a3918f7b270a4a2b83516 (the sidecar map is the MethodOptionsRegistry). (Word of warning: I have not tried to actually compile and run the gist, so you may find some small errors. But it should at least be instructive in showing everything you actually need.) ---- *Josh Humphries* jh...@bluegosling.com On Tue, Jul 18, 2017 at 1:40 PM, ran.bi via grpc.io < grpc-io@googlegroups.com> wrote: > What's the best way to get custom method option data ( > https://developers.google.com/protocol-buffers/docs/proto3#custom_options) > from server interceptors? > > -- > You received this message because you are subscribed to the Google Groups " > grpc.io" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to grpc-io+unsubscr...@googlegroups.com. > To post to this group, send email to grpc-io@googlegroups.com. > Visit this group at https://groups.google.com/group/grpc-io. > To view this discussion on the web visit https://groups.google.com/d/ > msgid/grpc-io/8756e7c5-a164-4ad3-b4d9-0d4f7b5d2239%40googlegroups.com > <https://groups.google.com/d/msgid/grpc-io/8756e7c5-a164-4ad3-b4d9-0d4f7b5d2239%40googlegroups.com?utm_medium=email&utm_source=footer> > . > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "grpc.io" group.
