Example 1: Filename: index.js
Javascript
// Node.js program to demonstrate the // request.statusCode method // Importing http module const http = require( 'http' ); // Setting up PORT const PORT = process.env.PORT || 3000; // Creating http Server const httpServer = http.createServer( function (request, response) { // Getting statusCode // by using request.statusCode method const value = request.statusCode; console.log(value) console.log(response.statusCode) // Display result response.end( "statusCode : " + value, 'utf8' , () => { console.log( "displaying the result..." ); httpServer.close(() => { console.log( "server is closed" ) }) }); }); // Listening to http Server httpServer.listen(PORT, () => { console.log( "Server is running at port 3000..." ); }); |
Run the index.js file using the following command.
node index.js
Output:
Server is running at port 3000... null 200 displaying the result... server is closed
Now go to http://localhost:3000/ in the browser, and you will see the following output:
statusCode : null
Example 2: Filename: index.js
Javascript
// Node.js program to demonstrate the // request.statusCode method // Importing http module const http = require( 'http' ); // Request and response handler const http2Handlers = (request, response) => { // Getting statusCode // by using request.statusCode method const value = request.statusCode; const msg = '' if (!value) { msg = 'Request statusCode Not Set' } else { msg = 'Request statusCode Set' } // Display result response.end(msg, 'utf8' , () => { console.log( "displaying the result..." ); httpServer.close(() => { console.log( "server is closed" ) }) }); }; // Creating http Server const httpServer = http.createServer( http2Handlers).listen(3000, () => { console.log( "Server is running at port 3000..." ); }); |
Run the index.js file using the following command.
