將 Go gRPC 調用轉換為 Node.js

Question

有一個 function 使用 grpc 調用從 grpc 節點獲取某些數據。

func GetVotesByAddr(r *http.Request, cli iotexapi.APIServiceClient) (proto.Message, error) {
    method := &iotexapi.ReadStakingDataMethod{
        Method: iotexapi.ReadStakingDataMethod_BUCKETS_BY_VOTER,
    }
    methodData, err := proto.Marshal(method)
    if err != nil {
        return nil, err
    }
    vars := mux.Vars(r)
    readStakingdataRequest := &iotexapi.ReadStakingDataRequest{
        Request: &iotexapi.ReadStakingDataRequest_BucketsByVoter{
            BucketsByVoter: &iotexapi.ReadStakingDataRequest_VoteBucketsByVoter{
                VoterAddress: vars["addr"],
                Pagination: &iotexapi.PaginationParam{
                    Offset: uint32(0),
                    Limit:  uint32(1000),
                },
            },
        },
    }
    requestData, err := proto.Marshal(readStakingdataRequest)
    if err != nil {
        return nil, err
    }
    request := &iotexapi.ReadStateRequest{
        ProtocolID: []byte("staking"),
        MethodName: methodData,
        Arguments:  [][]byte{requestData},
    }

    response, err := cli.ReadState(context.Background(), request)
    if err != nil {
        return nil, err
    }

    bucketlist := &iotextypes.VoteBucketList{}
    if err := proto.Unmarshal(response.Data, bucketlist); err != nil {
        return nil, err
    }
    return bucketlist, nil
}

代碼取自https://github.com/iotexproject/pharos/blob/master/handler/handler_votes.go

我需要將其轉換為 js，我正在使用這個庫https://docs.iotex.io/native-development/reference-code/call-any-rpc-method ，它支持使用 js 進行 ioTex 網絡的 rpc 調用。

const state = await antenna.iotx.readState({
    protocolID: "",
    methodName: "",
    arguments: "",
});

RPC調用文檔https://docs.iotex.io/reference/node-core-api-grpc#readstate

關於如何從 GO 到 Node.js 重建此調用的任何幫助都會有所幫助。

好的，所以在玩了一下之后，我自己解決了這個問題，下面是供將來參考的代碼

const state = await antenna.iotx.readState({
  protocolID: Buffer.from("staking"),
  methodName: IReadStakingDataMethodToBuffer({
    method: IReadStakingDataMethodName.BUCKETS_BY_VOTER,
  }),
  arguments: [
    IReadStakingDataRequestToBuffer({
      bucketsByVoter: {
        voterAddress: ioAddress,
        pagination: {
          offset: 0,
          limit: 1000,
        },
      },
    }),
  ],
  height: undefined,
});
