NetMQ DealerSocket fails to receive message










1















My Python3 server code:



import zmq
context = zmq.Context()
router = context.socket(zmq.ROUTER)
router.bind("tcp://*:1337")

router.send_multipart([b'build_0', b''])

while True:
pass


My C# client code:



/// <summary>
/// Receive data from server.
/// </summary>
private void RecvFromServer()

// Init the socket.
recvFromServerSocket = new DealerSocket();
recvFromServerSocket.Options.Identity = StringToByteArray("build_0");
recvFromServerSocket.Connect(NETWORK_PREFIX + serverAddress + PORT_INFIX + recvFromServerPort);

NetMQMessage frames = new NetMQMessage();

// When the socket is ready, receive a multipart message.
recvFromServerSocket.ReceiveReady += (o, s) =>

onBeginListenToServer?.Invoke(ref BenchmarkData.benchmark.began_to_listen_to_server);
frames = s.Socket.ReceiveMultipartMessage();
foreach (NetMQFrame frame in frames)

Debug.Log(frame.ConvertToString());
messagesFromServer.Enqueue(frame.ConvertToString());

frames.Clear();

onReceivedMessage?.Invoke(ref BenchmarkData.benchmark.received_from_server);
;

// Init the poller.
recvFromServerPoller = new NetMQPoller recvFromServerSocket ;

// Run the poller.
recvFromServerPoller.Run();



Right now, the message will not be received by the C# client.



However, if I set the Python socket to zmq.DEALER, the client will receive the message, but will treat build_0 as part of the multipart message, rather than the sender ID. I need the ID to actually be accepted, as there will be multiple clients. Python dealer sockets with an identity of build_0 can communicate with the server example.



How do I set up a NetMQ DealerSocket to accept any messages from a pyzmq router socket while using identities properly?
