Node.jsでPOSTデータを使う

sample.js

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

app.post('/send/', function(req, res){
	var s1 = req.body.s1 ? req.body.s1: 0,
			s2 = req.body.s2 ? req.body.s2: 0,
			s3 = req.body.s3 ? req.body.s3: 0;

	io.sockets.emit('socket_sensor', [s1, s2, s3]);
	res.send('OK');
});
