hi 我在rpc定义的了一个方法 返回了一个adIds []int64，在通过api调用接收后， 结构体被当作空值 未被解析，返回adIds 返回nil， 通过grpcui，是能够正确获取到 adIds的值为 [ ] , 去掉pb里面的 omitempty 也是一样为nil

type MediaMaterial struct {
	state         protoimpl.MessageState
	sizeCache     protoimpl.SizeCache
	unknownFields protoimpl.UnknownFields

	Title      string  `protobuf:"bytes,1,opt,name=title,proto3" json:"title,omitempty"`
	MatUrl     string  `protobuf:"bytes,2,opt,name=mat_url,json=matUrl,proto3" json:"mat_url,omitempty"`
	Mid        string  `protobuf:"bytes,3,opt,name=mid,proto3" json:"mid,omitempty"`
	Designer   string  `protobuf:"bytes,4,opt,name=designer,proto3" json:"designer,omitempty"`
	AdNumber   int64   `protobuf:"varint,5,opt,name=ad_number,json=adNumber,proto3" json:"ad_number,omitempty"`
	CreateTime string  `protobuf:"bytes,6,opt,name=create_time,json=createTime,proto3" json:"create_time,omitempty"`
	Type       int64   `protobuf:"varint,7,opt,name=type,proto3" json:"type,omitempty"`
	AdIds      []int64 `protobuf:"varint,8,rep,packed,name=ad_ids,json=adIds,proto3" json:"ad_ids,omitempty"`
}

A packed repeated field containing zero elements does not appear in the encoded message

Example code?

Is it controlled by the logic code in API service?

Would you please show me the full code on this issue?

sorry. I didn't see it until now

rpc logic return

func (l *PingLogic) Ping(in *pb.Request) (*pb.Response, error) {
	// todo: add your logic here and delete this line
	//Ids := make([]string, 0)
	return &pb.Response{Pong: in.Ping, Ids: []string{}}, nil
}

api get rpc response

paymentResp, err := l.svcCtx.PaymentRpc.Ping(l.ctx, &pb.Request{
		Ping: "11111",
	})
	if err != nil {
		return nil, err
	}

	fmt.Printf("print === %+v \n", paymentResp)`

console

grpcui

expect to return an empty slice as grpcui result { "pong": "1111", "Ids": [] }
