In node js there is an node module like http. Now include the http module into server file. By using this node module we can call webservices also.

var http = require('http');

Syntax for make http request.

try{
		var Authorization = "Basic " + new Buffer("username:password").toString("base64");
		var options = {
			host: 'IP_ADDRESS',
			port: PORT_NUMBER,
			method: 'GET',
			headers : {
				"Authorization" : Authorization
			}
		};
		
		var reqp = http.request(options, function(resp) {
			resp.setEncoding('utf8');
			resp.on('data', function (chunk) {
				// the response is in string format. So we need to convert to json.
				var resdata = JSON.parse(chunk);
				console.log(resdata);
			});
		});

		req.on('error', function(e) {
		  console.log('problem with request: ' + e.message);
		});

		// write data to request body
		reqp.write('data\n');
		reqp.write('data\n');
		reqp.end();			
}catch(e){
	console.log(e);
}
