NodeJS http

http server

A basic example of HTTP server.

write following code in http_server.js file:

var http = require('http');
var httpPort = 80;
http.createServer(handler).listen(httpPort, start_callback);
function handler(req, res) {

 var clientIP = req.connection.remoteAddress;
 var connectUsing = req.connection.encrypted ? 'SSL' : 'HTTP';
 console.log('Request received: '+ connectUsing + ' ' + req.method + ' ' + req.url);
 console.log('Client IP: ' + clientIP);
 res.writeHead(200, "OK", {'Content-Type': 'text/plain'});
 res.write("OK");
 res.end();
 return;
}
function start_callback(){
 console.log('Start HTTP on port ' + httpPort)
}

then from your http_server.js location run this command:

node http_server.js

you should see this result:

> Start HTTP on port 80

now you need to test your server, you need to open your internet browser and navigate to this url:

http://127.0.0.1:80

if your machine running Linux server you can test it like this:

curl 127.0.0.1:80

you should see following result:

ok

in your console, that running the app, you will see this results:

> Request received: HTTP GET /
> Client IP: ::ffff:127.0.0.1
