Node js url.parse—href not returning the full url

I have the following very simple code snippet in node.js (running under Windows 7)

var path = url.parse(req.url, true).pathname;
var href = url.parse(req.url, true).href;

console.log("path " + path + "\r\n");
console.log("href " + href + "\r\n");

I invoke the listener with localhost:8080/test

I would expect to see:

path /test
href /localhost:8080/test

Instead I get 

path /test
href /test

Why is href not the the full url?

As @adeneo said in the comment, req.url only contains the path. There are two solutions, depending on whether you are using express or not.

If using express: You need to do the following:

var href = req.protocol + "://"+ req.get('Host') + req.url;
console.log("href " + href + "\r\n");

This wil output:

http://localhost:8080/test

Reference: http://expressjs.com/4x/api.html#req.get

If using node's http server: Use the request's headers:

var http = require('http');
http.createServer(function (req, res) {
  var href = "http://"+ req.headers.host + req.url;
  console.log("href " + href + "\r\n");
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(1337, '127.0.0.1');
