node.js express.js post data - express

Question

I encountered a problem in getting client POST data as follow:
my client sent:
content-type:application/x-www-form-urlencoded
the content:
{"value":"123456"}
In node.js, it is no problem to parse the content to a json object, my code as follow:
http.createServer(function onRequest(request, response) {
request.setEncoding("utf8");
var content = [];
request.addListener("data", function(data) {
content.push(data); //Collect the incoming data});
//At the end of request call
request.addListener("end", function() {
response.writeHead( 200, {"Content-Type": "text/plain"} );
ms = content[0];
if(ms.toString() != "")
{
var msg = ms.toString(); //Parse the ms into string
console.log(msg); // Prints the message in the console
var reqObj = JSON.parse(msg); // If the incoming message is in JSON format, it can be parsed as JSON.
console.log(reqObj);
response.end(); //Close the response
}
});
Output of the above code:
{"account": "48264"} //before parse to JSON
{ account: '48264' } //after parse to JSON
but when I changed into express.js and use bodyParser, it mixed up.
var express = require('express');
var router = express.Router();
/* GET users listing. */
router.post('/', function(req, res, next) {
req.setEncoding('utf8');
console.log(req.body);
console.log(req.body.value);
});
module.exports = router;
The above outputs in the console as follow:
{ "{\"account\": \"123456\"}": "" }
undefined
I searched the web, but can't find the solution. please help.
Thanks in advance

You need to use express body-parser middleware before defining any routes.
var bodyParser = require('body-parser');
var app = express();
port = parseInt(process.env.PORT, 10) || 8080;
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: true }));
// parse application/json
app.use(bodyParser.json());
app.listen(port);
app.post("/someRoute", function(req, res) {
console.log(req.body);
res.status(200).json({ status: 'SUCCESS' });
});
