我有一个带有简单的zeroMQ响应器的node.js应用程序,该应用程序侦听端口5555并将其收到的消息回传给发送方。
我正在尝试测试侦听器是否正在接收消息,但是
1)建立连接后,netcat无法正确发送以下标准输入
要么
2)听众没有收到消息吗?
终端输出:(stdin在怪异的字符之后开始-也不确定为什么netcat在连接后输出它)
$ nc -vv localhost 5555
nc: connectx to localhost port 5555 (tcp) failed: Connection refused

app.js:
const zmq = require('zeromq');
// ==================== zeromq response ====================
// socket to talk to clients
var responder = zmq.socket('rep');
responder.on('message', function(request) {
console.log(request);
console.log("Received request: [", request.toString(), "]");
// do some 'work'
setTimeout(function() {
// send reply back to client.
responder.send(request.toString());
}, 1000);
});
responder.bind('tcp://127.0.0.1:5555', function(err) {
if (err) {
console.log(err);
} else {
console.log("Listening on 5555…");
}
});
process.on('SIGINT', function() {
responder.close();
});
