Syntax: const request.removeHeader(name)Parameters: This method takes the name of the header as a parameter. Return Value: This method has nothing to return. Example 1: Filename-index.js JavaScript // Node.js program to demonstrate the // request.removeHeader() method // Importing http module const http = require('http'); // Create an HTTP server http.createServer((req, res) => {}) .listen(3000, '127.0.0.1', () => { // Getting client request const req = http.request({ port: 3000, host: '127.0.0.1', }); req.setHeader('content-type', 'text/html'); console.log("before operation :- " + req.getHeader('content-type')) // Removing header // by using removeHeader() method req.removeHeader('content-type') console.log("after operation :- " + req.getHeader('content-type')) process.exit(0) }); Run the index.js file using the following command: node index.jsOutput: before operation :- text/html after operation :- undefinedExample 2: Filename-index.js JavaScript // Node.js program to demonstrate the // request.removeHeader() method // Importing http module const http = require('http'); // Create an HTTP server const server = http.createServer((req, res) => { res.writeHead(200, { 'Content-Type': 'text/plain' }); res.end('okay'); }); // Now that server is running server.listen(3000, '127.0.0.1', () => { // Make a request const options = { port: 3000, host: '127.0.0.1', headers: { 'Connection': 'Upgrade', 'Upgrade': 'websocket' } }; // Getting client request const req = http.request(options); req.setHeader('Cookie', ['type=ninja', 'language=javascript']); console.log("before operation :- " + req.getHeader('Cookie')) // Removing header // by using removeHeader() method req.removeHeader('Cookie') console.log("after operation :- " + req.getHeader('Cookie')) process.exit(0) }); Run the index.js file using the following command: node index.jsOutput: before operation :- type=ninja,language=javascript after operation :- undefinedReference: https://nodejs.org/dist/latest-v12.x/docs/api/http.html#http_request_removeheader_name Comment More infoAdvertise with us Next Article Node.js http.ClientRequest.setHeader() Method R rohitprasad3 Follow Improve Article Tags : Web Technologies Node.js Node.js-Methods Node.js-HTTP-Module Similar Reads http.Agent MethodNode.js new Agent() MethodThe Node.js HTTP API is low-level so that it could support the HTTP applications.
