Node.js 요청을 기록하는 방법

Node.js 요청을 기록하는 방법은 무엇입니까? console.log(req);를 사용하는 경우Node.js 요청을 기록하는 방법

var http = require('http'); 
http.createServer(function handler(req, res) { 
    console.log(req); 
}).listen(1337, '127.0.0.1'); 
console.log('Server running at http://127.0.0.1:1337/');

예를 들어, 나는 req 목적은 아래를 참조 길어질하지만 같은 훨씬 짧은해야 로깅.

GET/HTTP/1.1 
Host: 127.0.0.1:1337 
Connection: Keep-Alive 
User-Agent:

나는 http.IncomingMessage에 문서를 읽을 수는 있지만 한 번에 모든 주요 값을 얻을 수있는 방법이 없습니다. 가장 가까운

Server running at http://127.0.0.1:1337/ 
GET/1.1 { host: '127.0.0.1:1337', 
    connection: 'Keep-Alive', 
    'user-agent': 'RestClient-Tool' }
