The function passed into the http.createServer() has a req argument that represents the request from the client, as an object (http.IncomingMessage object).
This object has a property called “url” which holds the part of the url that comes after the domain name:
1 2 3 4 5 6 | var http = require('http'); http.createServer(function (req, res) { res.writeHead(200, {'Content-Type': 'text/html'}); res.write(req.url); res.end(); }).listen(8080); |
Save the code above in a file called “demo_http_url.js” and initiate the file:
1 | C:\Users\Your Name>node demo_http_url.js |
If you have followed the same steps on your computer, you should see two different results when opening these two addresses:
1 | /summer |
http://localhost:8080/winter
1 | /winter |
Split the Query String
There are built-in modules to easily split the query string into readable parts, such as the URL module.
1 2 3 4 5 6 7 8 9 | var http = require('http'); var url = require('url'); http.createServer(function (req, res) { res.writeHead(200, {'Content-Type': 'text/html'}); var q = url.parse(req.url, true).query; var txt = q.year + " " + q.month; res.end(txt); }).listen(8080); |
Save the code above in a file called “demo_querystring.js” and initiate the file:
1 | C:\Users\Your Name>node demo_querystring.js |
The address:
http://localhost:8080/?year=2017&month=July
1 | 2017 July |
