// 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', () => {
console.log("Server is started")
// Making a request
const options = {
port:3000,
host:'127.0.0.1',
headers:{
'Connection':'Upgrade',
'Upgrade':'websocket'
}
};
// Getting client request
const req = http.request(options);
// Aborting the request
// by using abort() method
req.abort()
// Emit the message
req.on('abort',()=>{
console.log("client request is aborted")
})
});
使用以下命令运行index.js文件:
node index.js
输出:
client request is aborted

.listen(3000, '127.0.0.1', () => {
// Getting clinet request
const req = http.request({
port:3000,
host:'127.0.0.1',
