how to send request strcut with bytes?

[ray1888]

syntax = "proto3";
package protobuf;

message Request{
    string method_name = 1;
    bytes arg = 2;
}

message Response{
    bytes res = 1;
}

service RemoteCall{
  rpc get_result(Request) returns(Response){}
  rpc get_feature(Request) returns(Response){}
  rpc get_detectResult(Request) returns(Response){}
  rpc get_emotion(Request) returns(Response){}
}

the protobuf file as above , how can i send bytes on your cli tools?

i use like this , and it doesn't work well

./ghz -proto ./call.proto -call protobuf.RemoteCall.get_result -d '{"method_name":"GET", "arg":"(lp0\nS'GET'\np1\naS'1'\np2\naS'cp431'\np3\na(dp4\nS'group_name'\np5\ng3\nsa."}' -n 2000 -c 50 172.17.82.212:8902

I am not sure how to accomplish this practically, I'll have to think about it look into it further.

so mark it as a feature request?@bojand

One option would be to provide support for reading binary serialized data. So for example you would provide a file (or via stdin) with the full message that's been serialized using protobuf. We could read it unmarshal it and use it as payload.

Protobuf's encoding of strings is described here, which should be similar to how bytes are handled: https://developers.google.com/protocol-buffers/docs/encoding#types

I like the idea of pre-serializing the binary data and feeding that as an input file/stdin. (Or having ghz use protobuf to serialize a binary file provided as input.)

+1 for this feature request. I don't have a use for this tool without this feature.

Hello, I agree this would be useful. The issue got a bit forgotten. I'll try and implement something soon-ish as I find the time. Thanks.

Hello, can you try the 0.14.0 release and check if it works for your use cases. I am closing this issue. If there are problems please feel free to open a new issue with all the details.
