如何記錄Node.js請求

如何記錄Node.js請求？如何記錄Node.js請求

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/');

例如，使用console.log(req);的時候，我得到長req對象見下文，但用於記錄它應該像短得多。

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

我讀了http.IncomingMessage文檔，但沒有方法一下子讓所有的主要價值。最接近的是

console.log(req.method, req.url, req.httpVersion, req.headers);

與輸出

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' }

完全req對象

它會更短嗎？ – 2014-10-20 07:54:26

這是關於如何格式化字符串的問題嗎？肯定沒有內置的方法來獲得你想要的輸出。 – jgillich 2014-10-20 07:58:20

console.log(req.method, req.url, 'HTTP/' + req.httpVersion); 
for (var name in req.headers) 
    console.log(name + ':', req.headers[name]);
