node.js - 如何在nginx中正确使用morgan？

伺服器：Ubuntu 18.04
节点：9.11.2
Npm：6.6.0
摩根：1.9.1
温斯顿：3.1.0
Nginx：1.14.0（Ubuntu）


我在带有nginx的ubuntu服务器上有一个nodejs应用程序。
为错误日志安装winston和morgan，但是我的应用程序不使用winston，它仅在我的nginx access.log文件（var / log / nginx / access.log）中注册http请求。
它也不会生成我需要的app.log文件。
好像我的应用程序出于某种原因而忽略了将morgan与winston一起使用。

我的app.js

var express = require('express');
var compression = require('compression')
var path = require('path');
var morgan = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');

var author = require('./routes/author');
var post = require('./routes/post');
var user = require('./routes/user');
var photo = require('./routes/photo');

var winston = require('./lib/config/winston');

var app = express();

app.use(morgan('combined', { stream: winston.stream }));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(compression());

var PAGING_COUNT = 10;
var MAX_PAGING_COUNT = 50;

app.use(function(req, res, next) {
  var s, c;
  if(!req.query) {
    s = 0;
    c = PAGING_COUNT;
  }
  else {
    var s = parseInt(req.query.s);
    var c = parseInt(req.query.c);
    if(!s) s = 0;
    if(!c) c = PAGING_COUNT;
  }
  if(c > MAX_PAGING_COUNT) {
    var err = new Error('Limit Request');
    err.status = 400;
    return next(err);
  }
  req.paging = { start: s, count: c};
  next();
});

app.use(function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, api_key, Authorization");
  res.header("Access-Control-Expose-Headers", "Origin, X-Requested-With, Content-Type, Accept, api_key, Authorization");
  res.header("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE");
  next();
});

app.use('/author', author);
app.use('/post', post);
app.use('/user', user);
app.use('/photo', photo);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500).send(err.message);
});

module.exports = app;

我的winston.js（./lib/config/winston.js）

var winston = require('winston');
var appRoot = require('app-root-path');

// Defino las configuraciones personalizadas para cada transporte (file, console).
var options = {
    file: {
      level: 'info',
      filename: `${appRoot}/logs/app.log`,
      handleExceptions: true,
      json: true,
      maxsize: 5242880, // 5MB
      maxFiles: 5,
      colorize: false,
    },
    console: {
      level: 'debug',
      handleExceptions: true,
      json: false,
      colorize: true,
    },
  };

// Nueva instancia de Winston
var logger = winston.createLogger({
    transports: [
        new winston.transports.File(options.file),
        new winston.transports.Console(options.console)
    ],
    exitOnError: false, // do not exit on handled exceptions
  });

// Funcion de flujo que permite a Winston capturar resultados de Morgan
logger.stream = {
    write: function(message, encoding) {
      // Uso el nivel 'info' para que la salida sea recogida por ambos transportes (file y console)
      logger.info(message);
    },
  };

module.exports = logger;

我的Nginx服务器配置

server {
    listen 80;
    listen [::]:80;

    #your subdomain
    server_name api.mydomain.com;

    location /v1/ {
        rewrite ^/v1/?(.*) /$1 break;
        proxy_buffering off;
        #your aplication port
        proxy_pass http://localhost:9000;
    }

    location /start/ {
        rewrite ^/start/?(.*) /$1 break;
        proxy_buffering off;
        #your aplication port
        proxy_pass http://localhost:8080;
    }
}
server {
    server_name storage.mydomain.com;
    root /home/ubuntu/app-backend/public/;
    index index.html;
    location /files {
        try_files $uri =404;
    }
}
server {
    listen 80;
    listen [::]:80;
    #point to build directory
    root /home/ubuntu/app-frontend/build;
    index index.html index.htm;

    server_name admin.mydomain.com;
    location / {
        root /home/ubuntu/app-frontend/build;
        try_files $uri $uri/ /index.html;
    }
}

在我的本地服务器上，我得到以下内容

{"message":"::1 - - [23/Jan/2019:04:36:41 +0000] \"PUT /author/push/012c2cab HTTP/1.1\" 200 17 \"http://localhost:3000/home/page/1\" \"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36\"\n","level":"info"}

在生产服务器中，我得到以下信息

MY_IP - - [23/Jan/2019:06:35:33 +0000] "PUT /v1/author/push/6a839012 HTTP/1.1" 500 20 "http://admin.mydomain.com/home/page/1" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36"

最佳答案

您不对morgan或winston使用流

您必须使用Stream Transport

var accessLogStream = fs.createWriteStream(path.join(__dirname, 'app.log'), { flags: 'a' })

logger.add(new winston.transports.Stream({
  stream: accessLogStream
  /* other options */
}));

然后将accessLogStream用于morgan morgan - write logs to a file

app.use(morgan('combined', { stream: accessLogStream }))
