[JS] [Node.js] Express error on windows evirement

說明

'http://user:pass@host.com:8080/p/a/t/h?query=string#hash'

The issue is that request.url doens't contain the hash, because the
browser typically doesn't send the hash, so the server doesn't have
it.

can't get the hash of a url

I'm trying to get the hash of a url that's being passed in to my
simple http server, but the only params that appear to be in the uri
are the path and href. The following is my code:

var http = require('http'),
    url = require('url'),
    path = require('path');

http.createServer( function(request, response) {

    var uri = url.parse(request.url);

console.log( uri.hash );

    response.writeHead(200, {'Content-Type': 'text/plain'});
    response.end( uri.href );

}).listen(8080);

On the terminal, no uri.hash is being output, just undefined.

Node is even nicer.

node> require("url").parse('http://u:pw-hcDgGtZH8xNBDgjK7y7TUQ <at> public.gmane.org/path?arg=1#anchor')
{ href: 'http://u:pw-hcDgGtZH8xNBDgjK7y7TUQ <at> public.gmane.org/path?arg=1#anchor'
, protocol: 'http:'
, slashes: true
, host: 'u:pw@...'
, auth: 'u:pw'
, hostname: 'example.com'
, hash: '#anchor'
, search: '?arg=1'
, query: 'arg=1'
, pathname: '/path'
}

The issue is that request.url doens't contain the hash, because the
browser typically doesn't send the hash, so the server doesn't have
it, and can't put it on request.url.

According to the spec, the client MUST send the path portion, but MAY
send the protocol, hostname, and hash.  If there is a host header,
then the hostname in the request url MUST match the host header.

Browser behavior is convention only.  If node gets the hash, and/or
the hostname, then it will provide it on the request.url.
