javascript - 如何使用 Sequelize 正确设置 Winston 日志记录？

Question

我正在使用 Sequelize 配置 winston。我有以下内容:

const logger = winston.createLogger({
    level: 'info',
    format: winston.format.json(),
    transports: [
        new winston.transports.File({ filename: path.join('logs', 'error.log'), level: 'error' }),
        new winston.transports.File({ filename: path.join('logs', 'info.log'), level: 'info' }),
        new winston.transports.File({ filename: path.join('logs', 'combined.log') }),
    ],
});

const sequelize = new Sequelize(
    database.database,
    database.user,
    database.password,
    {
        host: database.host,
        dialect: 'mysql',
        logging: (msg) => logger.info(msg),
    }
);

但是，日志文件显示级别之前的消息:

{"message":"Database connection has been established successfully.","level":"info"}

此外，时间戳不会显示为 shown here .

任何修复？

const logger = winston.createLogger({
  level: 'info',
  format: winston.format.combine(winston.format.timestamp(), winston.format.json()),
  //^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  transports: [
    new winston.transports.File({ filename: path.join('logs', 'error.log'), level: 'error', timestamp: true }),
    new winston.transports.File({ filename: path.join('logs', 'info.log'), level: 'info', timestamp: true }),
    new winston.transports.File({ filename: path.join('logs', 'combined.log'), timestamp: true }),
  ],
});
