So, not clear what you mean... but this should work (without express):
var app = require('http').createServer(function (request, response) {
// print http orignal message like curl
// request.method, URL and httpVersion
console.log(request.method + ' ' + request.url + ' HTTP/' + request.httpVersion);
// request.headers
for (var property in request.headers) {
if (request.headers.hasOwnProperty(property)) {
console.log(property + ': ' + request.headers[property])
}
}
});
app.listen(3000);
Or this one with express middleware:
const express = require('express')
const app = express();
// middleware to track request message
app.use(function (req, res, next) {
console.log(req.method + ' ' + req.url + ' HTTP/' + req.httpVersion);
for (var property in req.headers) {
if (req.headers.hasOwnProperty(property)) {
console.log(property + ': ' + req.headers[property])
}
}
next();
});
// your routes
app.get('/', function (req, res, next) {
res.send('Hello World');
});
app.listen(3000);
