GRPC: Client ID or connection information?

Question

Is there a way to get the connection information on RPC calls from server side? Or maybe something like unique client ID?

Answer 1

gRPC now provide peer information (https://github.com/grpc/grpc-go/issues/334)

import ( "google.golang.org/grpc/peer" )

func (s *server) Hello(ctx context.Context, in *pb.HelloRequest) (*pb.HelloReply, error) {
  //p includes connection information
  p, ok := peer.FromContext(ctx)
  ....
  ....
}
