Nodejs perform specific actions based on the specific request path

1. Processing the request module (requesthandlers.js)

function Start () {

console.log ("Request handler ' start ' was called");

return "Hello start";

}

function upload () {

console.log ("Request handler ' upload ' was called");

return "Hello Upload";

}

Exports.start = start;

Exports.upload = upload;

2. Routing Module (route.js)

Function route (handle,pathname) {

Console.log ("about-route a request for" +pathname);

if (typeof handle[pathname] = = ' function ') {

return handle[pathname] ();

}else{

Console.log ("No request handler found for" + pathname);

return "404 Not Found";

}

}

Exports.route = route;

3. Server Module (server.js)

var http = require ("http");

var url = require ("url");

function Start (route,handle) {

function ONrequest (request,response) {

var pathname = Url.parse (request.url). Pathname;

if (pathname! = "/favicon.ico") {

Console.log ("Request for" + pathname + "received");

response.writehead (200,{"Content-type": "Text/plain"});

var content = route (handle,pathname);

Response.Write (content);

Response.End ();

}

}

http.createserver (onrequest). Listen (8888);

Console.log ("Server has started");

}

Exports.start = start;

4. Call the appropriate module (index.js)

var server = require ("./server");

var router = require ("./route");

var requesthandlers = require ("./requesthandlers");

var handle = {};

handle["/"] = Requesthandlers.start;

handle["/start"] = Requesthandlers.start;

handle["/upload"] = requesthandlers.upload;

Server.start (Router.route,handle);

5. Executive Index.js

Node Index.js

Visit: Http://localhost:8888/start

Output Result:

Hello start

Visit: Http://localhost:8888/upload

Output Result:

Hello Upload

Visit: Http://localhost:8888/other

Output Result:

404 Not Found
