Let's say my sample url is

http://example.com/one/two

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.

  1. The protocol is available as req.protocol. docs here

    1. Before express 3.0, the protocol you can assume to be 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 protocol
  2. The host comes from req.get('host') as Gopal has indicated

  3. 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.

  4. 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;

How to get current url path in express with ejs, protocol + '://' + req. get('host') + req. originalUrl; By using above example, you can get full page URL.

Instead of concatenating the things together on your own, you could instead use the node.js API for URLs and pass URL.format() the informations from express.

Example:

var url = require('url');

function fullUrl(req) {
  return url.format({
    protocol: req.protocol,
    host: req.get('host'),
    pathname: req.originalUrl
  });
}

For version 4.x you can now use the req.baseUrl in addition to req.path to get the full path. For example, the OP would now do something like:

I found it a bit of a PITA to get the requested url. I can't believe there's not an easier way in express. Should just be req.requested_url

But here's how I set it:

var port = req.app.settings.port || cfg.port;
res.locals.requested_url = req.protocol + '://' + req.host  + ( port == 80 || port == 443 ? '' : ':'+port ) + req.path;

How do I get the full url in Express? Often when we are building applications using ExpressJS, we will need to get information from our users. This can happen any number of ways but the two most popular are: URL Parameters These are information that are passed through the URL

Using url.format:

var url = require('url');

This support all protocols and include port number. If you don't have a query string in your originalUrl you can use this cleaner solution:

var requrl = url.format({
    protocol: req.protocol,
    host: req.get('host'),
    pathname: req.originalUrl,
});

If you have a query string:

var urlobj = url.parse(req.originalUrl);
urlobj.protocol = req.protocol;
urlobj.host = req.get('host');
var requrl = url.format(urlobj);

Express Request URL Properties. Cheatsheet | by The Den, Something I forget every time: An overview of Express' request object showing all URL properties at a glance. More properties are in the API� @Zugwait's answer is correct. req.param() is deprecated. You should use req.params, req.query or req.body.. But just to make it clearer: req.params will be populated with only the route values.

Here is a great way to add a function you can call on the req object to get the url

  app.use(function(req, res, next) {
    req.getUrl = function() {
      return req.protocol + "://" + req.get('host') + req.originalUrl;
    }
    return next();
  });

Express routing, For a full list, see app.METHOD. In fact, the routing methods can have more than one callback function as arguments. Route parameters are named URL segments that are used to capture the values specified at their position in the URL. Configure the Proxy.

Comments
  • FYI you can inspect the request object and look through but I am a hypocrite and found it on here.
  • @dave a client can send whatever headers it wants (as well as whatever URL, port, random non-HTTP garbage), however, at some point bogus or inaccurate headers will simply cause the protocol to fail. For example, in a virtual host environment, an incorrect "host" header will display a completely different web site. In the case of X-Forwarded-Protocol, that is usually not send by the actual client (browser) but by the reverse proxy (nginx/varnish/apache/whatever) that is serving HTTPS in front of your application.
  • Or use req.get('Host') instead of req.host which gives the host plus the port section.
  • Probably best to post a separate question for that. This question is about express.
  • The host parameter in the request headers can be spoofed. There's a possible "host header attack" if using the res.host this way. In the Django framework they have an 'allowed hosts' variable that is used to prevent such attack. I use a configuration variable that is my root_url which can be added to the req.url for completion. About the attack: skeletonscribe.net/2013/05/…
  • If you want to add req.originalUrl without parameters, simply do req.originalUrl.split("?").shift(). Source: stackoverflow.com/a/32118818/2037431
  • In my case the req.get('host') returns only the hostname part, not the port. Don't know why, but now I gather the port number from the settings, and use the hostname field, instead of host.
  • Instead of pathname, I think you mean path. Which includes search/querystring
  • This doesn't work for URL's that have a query string.
  • port variable has to be defined?
  • Does req.port exist? It is not in the Express documentation?
  • My bad. I assumed you would know what port you're serving off of and set that prior. I'll update the example again. You can also get it with req.app.settings.port
  • when req.protocol is empty, does it mean http?
