The http.ClientRequest.removeHeader() is an inbuilt application programming interface of class ClientRequest within the HTTP module which is used to remove a header that's already defined into the headers object.
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
// 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.js
Output:
before operation :- text/html after operation :- undefined
Example 2: Filename-index.js
// 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.js
Output:
before operation :- type=ninja,language=javascript after operation :- undefined
