Finding list of available grpc methods in an api

[Constantine]

Hi !

Is there any way to find out about the list of grpc methods available by an API?

[Carl Mastrangelo]

Yes, if the server has Server Reflection turned on.  It is currently off be default.  It requires that the API use protobuf.  You can send an RPC to the /grpc.reflection.v1alpha.ServerReflection/ServerReflectionInfo method.  It is defined in reflection.proto in each of the repositories.

If you are using Go, I've written a library that provides a better client API than just the streaming method on the generated service stub: github.com/jhump/protoreflect/grpcreflect

(It also speaks in terms of *desc.Descriptor types defined in that same repo, which is a much richer and more useful API than the raw *DescriptorProto messages defined in github.com/golang/protobuf/protoc-gen-go/descriptor)
