Req.body ={} after request post

I have this code js:

app.use(express.static(__dirname));
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json()); // support json encoded bodies

app.get('/', function(req, res){
res.sendFile(__dirname+'index.html')
});

app.get('/ins.html', function(req, res){
res.sendFile(__dirname+'ins.html')
});

app.post('/ins', function(req, res){
console.log(req.body)
res.redirect('/')
});

And this code html:

<form method="get" enctype="multipart/form-data" action="/ins"><p>  <strong>INSERISCI LA TUA CAGATA<br></strong>
                            <br><p>Username&nbsp</p> <input type="text" name="username" required><br>
                            <br><p>Password &nbsp</p> <input type="password" name="password" required><br><br><br>
                        <input type="submit" class="mainBtn" id="submit" value="Inserisci Cagata">
                        <p>
                    </form></h2>

When i go to the page, in che console show "{}" and i have not access in the POST variable. how can i solve the problem?
