Go中的grpc标头/ cookie

I want to do place on server application which can be called by Go APP and Java app both.

for some reason ,there's a cookie authentication and oAuth mechanism ,so I want to set one Go app as Auth Micro-service for the authentication purpose.

As GRPC is built on the HTTP2 ,so The headers and cookies are on the protocol.but I did not find out how to carry on header and cookie when the rpc occurs,implemented by Go, on GitHub I only found the JAVA-Implementation for headers at :

https://github.com/grpc/grpc-java/tree/master/examples/src/main/java/io/grpc/examples/header

Can anybody give me some direction of Go implementation for this purpose?

Headers in gRPC are called "Metadata." Clients can only send "headers". Servers can send both "headers" and "trailers."

You want to use the google.golang.org/grpc/metadata package and metadata.NewContext() to send metadata on the client-side. Use grpc.SendHeader() and grpc.SetTrailer() to send metadata on the server-side. Use the grpc.Header() and grpc.Trailer() CallOptions for receiving the Metadata on client-side. Use metadata.FromContext() for receiving metadata on server-side.
