how to replace google's protos when used in grpc gateway request

[kaisawind]

For example

// The file manager service definition.
service FileManager {
    rpc Hello(google.protobuf.Empty) returns (google.protobuf.Empty) {
        option (google.api.http) = {
            get: "/v1/hello"
        };
        option (grpc.gateway.protoc_gen_swagger.options.openapiv2_operation) = {
            responses: {
                key: "200"
            }
        };
    }
}

the code will be generate just like below

func request_FileManager_Hello_0(ctx context.Context, marshaler runtime.Marshaler, client FileManagerClient, req *http.Request, pathParams map[string]string) (proto.Message, runtime.ServerMetadata, error) {
    var protoReq empty.Empty
    var metadata runtime.ServerMetadata

    msg, err := client.Hello(ctx, &protoReq, grpc.Header(&metadata.HeaderMD), grpc.Trailer(&metadata.TrailerMD))
    return msg, metadata, err

}

empty.Empty can not be found by go when it be replaced by github.com/gogo/protobuf/types. How can i fix it?

This is fixed by using an M import parameter. See https://jbrandhorst.com/post/go-protobuf-tips/ for an example.

@johanbrandhorst Maybe I didn't make it clear,I'm sorry about that.

We can use M to fix import packages, but how about really codes? *.pb.go has been changed, but *pb.gw.go not. Please take a look at empty.Empty.

*.pb.go *pb.gw.go

[kaisawind]

By the way, all *.pb.go and *pb.gw.go imports have been changed.

*.pb.go *pb.gw.go

That one is a bug in the gRPC gateway generator. See https://jbrandhorst.com/post/gogoproto/

Thank you very much.
