描述

Due to backward compatibility issue, I am forced to use proto2. I am not sure if my clients can keep on using proto2 and I can move to proto3. Also it is recommended to keep using proto2 as proto3 doesn't have many new features.

So, if I am supposed to use proto2 only, is there a workaround for it given bytes_type and enums are not supported?

研究方向
Identify the `proto2ConvertFuncs` structure in the source code, likely in `protoc gen grpc gateway/internal/gengateway/template.go`. Review existing handler implementations for proto3 to understand the pattern. Add conversion functions for bytes and enum types for proto2, ensuring they match the expected output format. Check the issue comments for any suggested workarounds that might inform the implementation.
