Question

场景：我可以使用以下代码通过ZeroMQ（ØMQ）将字符串类型的数据从C＃发送到Node.JS应用程序：
C＃推送代码：

using (var context = new Context(1))
                {
                    using (Socket client = context.Socket(SocketType.PUSH))
                    {
                        client.Connect("tcp://127.0.0.1:12345");
                        int i = 0;
                        while (true)
                        {
                            string request = i.ToString() + "_Hello_ ";
                            i++;
                            Console.WriteLine("Sending request..." + i.ToString());
                            client.Send(request, Encoding.Unicode); 

                              // <== Here is the issues    
                            string reply = client.Recv(Encoding.Unicode).ToString(); 
                              // <== Here is the issues

                            Console.WriteLine("Received reply :", reply);
                        }
                    }
                }

Node.JS拉码：

pull_socket.bindSync('tcp://127.0.0.1:12345')

pull_socket.on('message', function (data) {
    i++;
    console.log(i.toString() + 'received data:\n');
    console.log(data.toString());
    pull_socket.send('rcvd'); // <== Here is the issues
});

问题：在C＃reply对象中将包含字符串"Not supported"，但发送的数据将在Node.js中正确接收。

问题：可以告诉我我做错了吗？请详细说明这个问题。

高级谢谢

通过使用不同的套接字类型REQ / REP而不是PUSH / PULL来解决它以下是代码：
C＃推送代码：

using (var context = new Context(1))
                {
                    using (Socket client = context.Socket(SocketType.REQ))
                    {
                        client.Connect("tcp://127.0.0.1:12345");
                        int i = 0;
                        while (true)
                        {
                            string request = i.ToString() + "_Hello_ ";
                            i++;
                            Console.WriteLine("Sending request..." + i.ToString());
                            client.Send(request, Encoding.Unicode); 

                            string reply = client.Recv(Encoding.Unicode).ToString();

                            Console.WriteLine("Received reply :" + reply);
                        }
                    }
                }

Node.JS拉码：

var rep_socket = zmq.socket('rep')
rep_socket.bindSync('tcp://127.0.0.1:12345')

rep_socket.on('message', function (data) {
    i++;
    console.log(i.toString() + 'received data:\n');
    console.log(data.toString());
    pull_socket.send('hello WORLD'); // <== Here is the issues
});

C＃控制台上的输出：

Sending request...0
Received reply: hello WORLD
