示例 1:
Javascript
// Node.js program to demonstrate the
// request.end() APi
// 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');
// finishing sending the request
req.end()
// getting header
// by using getHeader() api
console.log("header :- " + req.getHeader('content-type'))
process.exit(0)
});
Javascript
// Node.js program to demonstrate the
// request.end() APi
// 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']);
// getting header
// by using getHeader() api
const v = req.getHeader('Cookie');
// finishing sending the request
req.end()
// display the result
console.log("header :- " + v)
process.exit(0)
});
