I'm currently trying to design a simple browser app utilizing express. console.log(req.body) comes back {} and i cant find the solution, been here for the best part of the day lol

Here's my app

var express = require('express');
var path = require('path');
var logger = require('morgan');
var bodyParser = require('body-parser');

var app = express();

app.use(logger('dev'));
app.use(bodyParser.json());
app.use(express.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(express.static(path.join(__dirname, 'public')));

app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');



app.get('/', function(req, res){
    console.log(req.body);

    res.render('index', {
        infoVoos: 'acesso_inicial'
    });
});

app.post('/pesquisar', function(req,res){

    console.log("");
    console.log("");
    console.log(req.body);

   
            res.send('ok');    
});

app.listen(3000);

console.log('############');
console.log('Server on');
console.log('');

module.exports = app;

I changed the parameter of the input tag from "id" to "name" and it's working fine now.

original

<form action="/pesquisar" method="post">
    <input type="text" id="cO">
    <input type="text" id="cD">
    <input type="submit">
</form>

new

<form action="/pesquisar" method="post">
    <input type="text" name="cO">
    <input type="text" name="cD">
    <input type="submit">
</form>

thankx guys
