I have a question about routing and urls in general. My question regards parameters or queries in the url before the domain itself. For example:
I ask this question because I am using ExpressJS and you only define your routes after the domain itself like:
Which would be added to the end of the url. What I want is to be able to store parameters inbefore the domain itself.
Thank you in advance!
FYI
I do know how to use parameters and queries, I just don't know how I would go about to insert them before the domain.
Maybe this vhost middleware is useful for your situation: https://github.com/expressjs/vhost#using-with-connect-for-user-subdomains
Otherwise a similar approach would work: create a middleware function that parses the url and stores the extracted value in an attribute of the request.
You can create an if statement which can look at the sub-domain through the express req.headers.host
variable which contains the domain of the request. For example:
-- google.com/anything/another
req.headers.host => "google.com"
-- docs.google.com/anything/
req.headers.host => "docs.google.com"
So working off this in your route you can call Next()
if the request doesn't match the form you want.
router.get('/', function(req, res, next) {
if (req.headers.host == "sub.google.com") {
//Code for res goes here
} else {
//Moves on to next route option b/c it didn't match
next();
}
});
This can be expanded on a lot! Including the fact that many packages have been created to accomplish this (eg. subdomain ) Disclaimer you may need to account for the use of www.
with some urls.
So I would use something like
router.get('/myRoute', function(req, res,next) {
req.headers.host == ":param.localhost.com"
//rest of code
}
I think I understand what you are saying, but I will do some testing and some further reading upon the headers of my request.
EDIT: Right now it seems like an unnecessary hassle to continue with this because I am also working with React-router at the moment. So for the time being I am just going to use my params after the /. I thank you for your time and your answers. Have a nice day!
