Javascript nodejs向基于winston的记录器添加行号

如何向以下基于winston的记录器添加行号？ 使行号显示在文件路径的末尾

const winston = require('winston');

winston.emitErrs = true;
const logger = function (module) {
    let parts, path;
    parts = module.filename.split('\\');
    path = parts[parts.length - 2] + '\\' + parts.pop();
    return new winston.Logger({
        transports: [
            new winston.transports.Console({
                level: 'debug',
                handleExceptions: true,
                json: false,
                colorize: true,
                label: path,
                timestamp: true
            })
        ],
        exitOnError: false
    });
};
module.exports = logger;

更新 当前输出示例如下所示：

2018-06-10T00:13:33.344Z-info:[app\main.js]这是我的日志

所需格式为：

2018-06-10T00:13:33.344Z-info:[app\main.js:150]这是我的日志

其中150追加到文件路径。

您可以在新文件

winston.js

中使用此代码。并通过在任何地方要求它来使用它

const winston = require('winston');

winston.emitErrs = true;
const logger = function (module) {
    let parts, path;
    parts = module.filename.split('\\');
    path = parts[parts.length - 2] + '\\' + parts.pop();
    return new winston.Logger({
        transports: [
            new winston.transports.Console({
                level: 'debug',
                handleExceptions: true,
                json: false,
                colorize: true,
                label: path,
                timestamp: true
            })
        ],
        exitOnError: false
    });
};
module.exports = logger;

var winston = require('winston')
var path = require('path')
var PROJECT_ROOT = path.join(__dirname, '..')
var appRoot = require('app-root-path');


const options = {
  file: {
    level: 'info',
    filename: `${appRoot}/logs/app.log`,
    handleExceptions: true,
    json: true,
    maxsize: 5242880, // 5MB
    maxFiles: 5,
    colorize: false,
    timestamp: true
  },
  console: {
    level: 'debug',
    handleExceptions: true,
    json: true,
    colorize: true,
    timestamp: true
  }
};

var logger = new winston.Logger({
  transports: [
    new winston.transports.File(options.file),
    new winston.transports.Console(options.console)
  ],
  exitOnError: false // do not exit on handled exceptions
});

logger.stream = {
  write: function (message) {
    logger.info(message)
  }
}

// A custom logger interface that wraps winston, making it easy to instrument
// code and still possible to replace winston in the future.

module.exports.debug = module.exports.log = function () {
  logger.debug.apply(logger, formatLogArguments(arguments))
}

module.exports.info = function () {
  logger.info.apply(logger, formatLogArguments(arguments))
}

module.exports.warn = function () {
  logger.warn.apply(logger, formatLogArguments(arguments))
}

module.exports.error = function () {
  logger.error.apply(logger, formatLogArguments(arguments))
}

module.exports.stream = logger.stream

/**
 * Attempts to add file and line number info to the given log arguments.
 */
function formatLogArguments (args) {
  args = Array.prototype.slice.call(args)

  var stackInfo = getStackInfo(1)

  if (stackInfo) {
    // get file path relative to project root
    var calleeStr = '(' + stackInfo.relativePath + ':' + stackInfo.line + ')'

    if (typeof (args[0]) === 'string') {
      args[0] = calleeStr + ' ' + args[0]
    } else {
      args.unshift(calleeStr)
    }
  }

  return args
}

/**
 * Parses and returns info about the call stack at the given index.
 */
function getStackInfo (stackIndex) {
  // get call stack, and analyze it
  // get all file, method, and line numbers
  var stacklist = (new Error()).stack.split('\n').slice(3)

  // stack trace format:
  // http://code.google.com/p/v8/wiki/JavaScriptStackTraceApi
  // do not remove the regex expresses to outside of this method (due to a BUG in node.js)
  var stackReg = /at\s+(.*)\s+\((.*):(\d*):(\d*)\)/gi
  var stackReg2 = /at\s+()(.*):(\d*):(\d*)/gi

  var s = stacklist[stackIndex] || stacklist[0]
  var sp = stackReg.exec(s) || stackReg2.exec(s)

  if (sp && sp.length === 5) {
    return {
      method: sp[1],
      relativePath: path.relative(PROJECT_ROOT, sp[2]),
      line: sp[3],
      pos: sp[4],
      file: path.basename(sp[2]),
      stack: stacklist.join('\n')
    }
  }
}

什么电话号码？日志消息已打印多少次？这样做的目的是什么？如果您的意思是其他特定的东西，那么您最好在问题中说明这一点。除非您自己提供，否则为什么日志消息中会包含源代码的行号？记录器不会“解析”您的源文件，它只是发出数据。只有在错误堆栈跟踪中才能看到未提供的行号。这似乎是一个非常简单有效的问题。记录器应该能够提供行号，我在过去处理过的大多数都是这样。这如何包括行号？
