Let's say my sample url is
and I say I have the following route
app.get('/one/two', function (req, res) {
var url = req.url;
}
The value of url
will be /one/two
.
How do I get the full url in Express?
For example, in the case above, I would like to receive http://example.com/one/two
.
The protocol is available as req.protocol
. docs here
http
unless you see that req.get('X-Forwarded-Protocol')
is set and has the value https
, in which case you know that's your protocolThe host comes from req.get('host')
as Gopal has indicated
Hopefully you don't need a non-standard port in your URLs, but if you did need to know it you'd have it in your application state because it's whatever you passed to app.listen
at server startup time. However, in the case of local development on a non-standard port, Chrome seems to include the port in the host header so req.get('host')
returns localhost:3000
, for example. So at least for the cases of a production site on a standard port and browsing directly to your express app (without reverse proxy), the host
header seems to do the right thing regarding the port in the URL.
The path comes from req.originalUrl
(thanks @pgrassant). Note this DOES include the query string. docs here on req.url and req.originalUrl. Depending on what you intend to do with the URL, originalUrl
may or may not be the correct value as compared to req.url
.
Combine those all together to reconstruct the absolute URL.
var fullUrl = req.protocol + '://' + req.get('host') + req.originalUrl;
