这是winston @ 3记录器的演示代码:
const { createLogger, format, transports } = require("winston")
const { combine, timestamp, prettyPrint } = format
const logger = createLogger({
format: combine(timestamp(), prettyPrint({ colorize: true }))
})
logger.add(new transports.Console())
logger.info("test message", { data: { a: 1, b: [1, 2, 3, 4], d: new Date() } })
它打印:
{ data: { a: 1, b: [ 1, 2, 3, 4 ], d: 2018-07-17T09:38:43.253Z },
level: 'info',
message: 'test message',
timestamp: '2018-07-17T09:38:43.253Z',
[Symbol(level)]: 'info',
[Symbol(splat)]:
[ { data: { a: 1, b: [ 1, 2, 3, 4 ], d: 2018-07-17T09:38:43.253Z } } ] }
我想从输出中删除一些字段:[Symbot(level)],[Symbot(splat)],所以我想要这样的输出:
{ data: { a: 1, b: [ 1, 2, 3, 4 ], d: 2018-07-17T09:38:43.253Z },
level: 'info',
message: 'test message',
timestamp: '2018-07-17T09:38:43.253Z' }
答案 0 :(得分:0)
您可以修改日志输出及其格式。这是官方文档:https://github.com/winstonjs/winston#streams-objectmode-and-info-objects
这里是示例:
logger.add(winston.transports.Console, {
level : 'error',
prettyPrint : true,
silent : false,
timestamp : true,
json : false
});
