温斯顿文件传输日志转义字符

Question

我正在使用 Winston 登录 Sails 应用程序。这是我的配置：

var customLogger = new winston.Logger({
    transports: [
        new(winston.transports.File)({
            level: 'debug',
            filename: 'app.log',
            colorize: false,
            showLevel: false,
            prettyPrint: false,
            exitOnError: false,
            json: true,
            zippedArchive: true,
            maxsize: 1000000000,
            maxFiles: 30,
            tailable: true
        }),
        new(winston.transports.Console)({
            level: 'info',
            exitOnError: false,
            colorize: false,
            showLevel: false
        })
    ],
});

但在输出文件中存在奇怪的字符。

{"level":"info","message":"\u001b[32minfo: \u001b[39m","timestamp":"2016-05-12T17:58:03.281Z"}

目前在航行中你不需要使用customLogger温斯顿。您可以安装sails-hook-winston。比你的config/log.js会看起来像这样：

var path = require('path');
var pkgJSON = require(path.resolve('package.json'));

module.exports.log = {

    // This options are for Console transport that is used by default
    level: 'info', // you are familiar with this value, right?
    timestamp: true, // if you want to output the timestamp in the console transport
    colors: false,
    // Transports
    // more information: https://github.com/winstonjs/winston/blob/master/docs/transports.md
    transports: [{
        module: require('winston-daily-rotate-file'),
        config: {
            dirname: path.resolve('logs'),
            datePattern: '.yyyy-MM-dd.log',
            filename: pkgJSON.name,
            prettyPrint: true,
            timestamp: true,
            level: 'info',
            json: true,
            colors: false
        }
    }]
};

您可以同时使用几种具有不同日志级别的传输。
