NodeJs Creating a Web server

The following is a demonstration of one of the most basic HTTP server architectures (using 8081 ports) to create the Ser.js file, as shown in the code below:

var http = require (' http '); var fs = require (' FS '); var url = require (' URL ');//Create server = Http.createserver (function (req , res) {//Resolve request, including file name Var pathname=url.parse (req.url). pathname;//the file name of the output request Console.log ("Request for" +pathname+ " Received. "); /Read the requested file contents from the file System Fs.readfile (PATHNAME.SUBSTR (1), function (Err,data) {if (err) {Console.log (err);//http Status Code 404:not Found//content type:text/htmlres.writehead (404,{' content-type ': ' text/html '});} Else{//http Status Code 200:ok//content type:text/htmlres.writehead (200,{' content_type ': ' text/html '});//Response File Contents Res.write ( Data.tostring ());} Send response data Res.end ();}); /Monitor 8000 port Server.listen (8000);//console Print information Console.log ("Server running on http://127.0.0.1:8000 ...");

　　

Next we create a index.htm file in this directory with the following code:

Execute the ser.js file:
E:\nodejs>node Serserver running on http://127.0.0.1:8000
