I want to extract my url id using the code under

var http =  require('http');
var fs = require('fs');
var url = require('url');

var app = http.createServer(function(request, response){
    var _url = request.url;
    var queryData = url.parse(_url, true).query;
    console.log(queryData);

    if(_url == '/'){
        _url = '/index.html';
    }
    if(_url == '/favicon.ico'){
        return response.writeHead(404);
    }
    response.writeHead(200);

    response.end(fs.readFileSync(__dirname + _url));
});

app.listen(4040);

However, whether than having a result like{id: 'HTML'}the terminal keeps sending me this code whenever I click my web pages

[Object: null prototype] {}

How to solve this problem?

have you tried using `queryData = req.query` – Noaman Ilyas Mar 26 '19 at 05:54
You don't need to use use `url` to get to the `query` parameters. Use `req.query.id` to access the query parameter named `id`. – ethane Mar 26 '19 at 05:55
That is normal, browser makes two request (sometime more than twice) – Kyaw Kyaw Soe Mar 26 '19 at 05:55
To link directory you need to use `_url = '\\index.html';` instead if `_url = '/index.html';` – kgangadhar Mar 26 '19 at 05:56
