index.html

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<title>express get & post</title>
</head>
<body>
	<form action="/testget" method="get">
		<label for="username">username:</label><input type="text" name="username"><br>
		<label for="password">password:</label><input type="password" name="password"><br>

index.js

var express = require('express');
var bodyParser = require('body-parser');
var app = express();

var urlencodedParser = bodyParser.urlencoded({

app.use(bodyParser.urlencoded({

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

app.get('/testget', function(req, res) {
	// http://localhost:8888/testget?username=hello&password=world
	var username = req.query.username;
	var password = req.query.password;

	console.log(username);
	console.log(password);
