Node.js - 日志记录/使用摩根和温斯顿 [英] Node.js - logging / Use morgan and winston
问题描述
我们使用 morgan
来记录我们的快速转换:
we use morgan
in order to log our express transformation:
var morgan = require('morgan');
morgan('combined');
// a format string
morgan(':remote-addr :method :url :uuid');
// a custom function
morgan(function (req, res) {
return req.method + ' ' + req.url + ' ' + req.uuid;
})
此外,我们使用 winston
来记录我们的其他日志:
Also, we use winston
in order to log our other logging:
var winston = require('winston');
var logger = new (winston.Logger)({
transports: [
new (winston.transports.Console)({ level: 'info' }),
new (winston.transports.File)({ filename: '/var/log/log-file.log' })
]
});
有没有办法将两个记录器结合在一起?现在的情况是 morgan
写入我的标准输出,当 winston
写入 /var/log/log-file.log
时.
Is there any way to combine the two loggers together? the situation now is that morgan
is write to my standard output, when winston
writes to /var/log/log-file.log
.
我希望记录器文件能够结合快速转换信息和我想要的其他信息 (logger.info()
)..
I wish that the logger file will combine from the express transformation information, and from the other information I want (logger.info()
)..

这篇文章非常适合您想做的事情.

对于您的特定代码,您可能需要这样的东西:
For your specific code you probably need something like this:
var logger = new winston.Logger({
transports: [
new winston.transports.File({
level: 'info',
filename: './logs/all-logs.log',
handleExceptions: true,
json: true,
maxsize: 5242880, //5MB
maxFiles: 5,
colorize: false
}),
new winston.transports.Console({
level: 'debug',
handleExceptions: true,
json: false,
colorize: true
})
],
exitOnError: false
});
logger.stream = {
write: function(message, encoding){
logger.info(message);
}
};
app.use(require("morgan")("combined", { "stream": logger.stream }));
这将设置 Winston 将日志和文件写入控制台.然后就可以使用最后一个表达式将摩根中间件的输出传递给 winston.
This will set up Winston to write a log to the console as well as a file. Then you can use the last expression to pass output from the morgan middleware into winston.
