Grpc-gateway: calling Enum by string name in requests using gogo/protobuf results in error.

[foolusion]

With the standard protoc_gen_go I can reference Enum's by their string name when using grpc-gateway. This is not the case when I use gogo binaries.

The related issue gogo/protobuf#286

This is because the grpc-gateway uses the golang/protobuf registered enum map for lookups. Like suggested in the link you provided you should use the goproto_registration extension to enable dual registration for your proto files.

See https://github.com/gogo/protobuf/blob/master/gogoproto/doc.go#L151

I'd love to get this into wiki/docs.

The goproto_registration extension solved my issue. Thanks!
