嗨，我想用nodejs winston登录514 udp端口。我想用相同的日志名称和不同的文件夹保存所有日志日志。示例/listen/2019/11/04/test.log第二天/listen/2019/11/05/test.log。我尝试但只保存1个日期，并且当日期更改时日志地址不会更改。

var winston = require('winston');
var d = new Date();
var year = d.getFullYear();
var month = (d.getMonth() + 1) ;
var day = d.getDate();
var n = d.getMinutes();
var shell = require('shelljs');
shell.mkdir('-p','/listen/test/'+year+'/'+month+'/'+day);

var logger = winston.createLogger({
  level: 'info',format: winston.format.simple(),defaultMeta: { service: 'user-service' },transports: [

    new winston.transports.File({ filename: 'error.log',level: 'error' }),new winston.transports.File({ filename: '/listen/test/'+year+'/'+month+'/'+day+'/test.log' })
  ]
});

var PORT = 514;
var HOST = '0.0.0.0';
var dgram = require('dgram');
var server = dgram.createSocket('udp4');
server.bind(PORT,HOST);

server.on('listening',function () {
    var address = server.address();
    console.log('UDP Server listening on ' + address.address + ":" + address.port);
});

server.on('message',function (message,remote) {
      logger.info(message);
});
