bunyan官方咕了7年了都没支持，js原生目前不支持装饰器，那就手动包装一下呗。
'use-strict';
const bunyan = require('bunyan');
const path = require('path');
function MyStream() {}
MyStream.prototype.write = function (rec) {
rec.level = bunyan.nameFromLevel[rec.level];
rec.time = new Date().toLocaleString();
};
const logger = bunyan.createLogger({
name: 'bot',
streams: [
{
level: 'debug',
stream: process.stdout
},
{
level: 'debug',
type: 'rotating-file',
path: path.normalize(__dirname + '/../..') + '/log/debug/debugs.log',
period: '4h',
count: 128
},
{
level: 'info',
type: 'rotating-file',
path: path.normalize(__dirname + '/../..') + '/log/info/infos.log',
period: '12h',
count: 32
},
{
level: 'warn',
type: 'rotating-file',
path: path.normalize(__dirname + '/../..') + '/log/warn/warns.log',
period: '24h',
count: 64
}
]
});
let warpLogger = {};
warpLogger.logger = logger;
warpLogger.debug = (obj, ...para) => {
logger.debug(obj, para.join(), new Date().toLocaleString('zh-CN'));
};
warpLogger.info = (obj, ...para) => {
logger.info(obj, para.join(), new Date().toLocaleString('zh-CN'));
};
warpLogger.warn = (obj, ...para) => {
logger.warn(obj, para.join(), new Date().toLocaleString('zh-CN'));
};
module.exports = warpLogger;
不过这种写法对于logger.info(format, ...params)的调用没有办法协调，希望有懂的在评论给出。
