You could follow the Go introduction that's in the gRPC docs.
The basic process is as follows:
1) Write the Protocol Buffers definitions for your data structures and a gRPC service definition that integrates them:
package fileserver
message FileRequest {
string name = 1;
}
message FileResponse {
bytes contents = 1;
}
service FileServer {
rpc ReadFile (FileRequest) returns (FileResponse) {}
}
2) Generate the gRPC/PB bindings using the "protoc" tool (you will need "protoc-gen-go" as well). The command is usually:
protoc --go_out=plugins=grpc:. *.proto
3) Implement the server:
type FileServer struct{}
func (s *FileServer) Dispatch(ctx context.Context, fileRequest *fileserver.FileRequest) (*fileserver.FileResponse, error) {
f, _ := ioutil.ReadFile(fileRequest.Name)
fileResponse := &fileserver.FileResponse{Contents: f}
return fileResponse, nil
}
