node.js - Winston日志模块中，为什么发送不同级别的日志不起作用

Question

在我的 Node 应用程序中，我使用 Winston 模块来存储我的应用程序日志。我尝试将日志存储在不同级别以及不同的文件中。在这种情况下，我收到错误“错误:传输已附加:文件”。

我的代码

  var winston=require('winston');
  winston.add(winston.transports.File, { filename: './logfile.log',level:'error' });
  winston.add(winston.transports.File, { filename: './logfile1.log',level:'warn' });
  winston.add(winston.transports.File, { filename: './logfile2.log',level:'debug'});

  winston.log('error', 'Error message!');//this should go to logfile.log
  winston.log('warn', 'Warning message!');//this should go to logfile1.log
  winston.log('debug', 'Debug message!');//this should go to logfile2.log

Answer 1

winston.add(winston.transports.File, { name:'log.error', filename: './logfile.log',level:'error' }); winston.add(winston.transports.File, { name:'log.warn', filename: './logfile1.log',level:'warn' }); winston.add(winston.transports.File, { name:'log.debug', filename: './logfile2.log',level:'debug'});

就这样吧!
