proxy pass header metadata

[liule]

hi,
Metadata can't pass client to server by grpc-proxy， what can I do to pass metadata , thanks a lot

Sorry, I don't understand.

Do toy mean: if a client request carries metadata, the grpc-proxy doesn't pass it to the backend?

That's weird because there's a test for that:
https://github.com/mwitkow/grpc-proxy/blob/master/proxy/handler_test.go#L118

this case by gRPC new version which make metadata to Income-metadata and Outcome-metadata, so that the grpc-proxy doesn't pass it to the backend, i have fix in my brench.

by add this code.

•   md, _ := metadata.FromContext(clientCtx)
  

•   clientCtx = metadata.NewOutgoingContext(clientCtx, md)
