温斯顿记录器不写入文件

Question

我想在 node 应用程序中使用 winston 记录器将错误记录到文件中。但是 winston 没有写入文件。

var logger = new (winston.Logger)({
             transports: [
                new (winston.transports.Console)(),
                new (winston.transports.File)({ filename: 'somefile.log' })
              ]
            });

 logger.error('test');

文件 somefile.log 已创建但为空。

您需要在构造函数中定义关卡。

var tsFormat = () => (new Date()).toLocaleTimeString();
var log = new (winston.Logger)({
    transports: [
        new (winston.transports.Console)({
            timestamp: tsFormat,
            colorize: true,
            level: 'info'
        }),
        new (winston.transports.File)({
            filename: 'somefile.log',
            level: 'error'
        })
    ]
});


log.error('test'); // writes to log and console out
log.info('testing info'); // writes just in console
