[Edit] ---- Adding body parser outside the route
var express = require('express')
, http = require('http');
var app = express();
app.set('port', process.env.PORT || 7002);
app.use(express.static(__dirname + '/public/images'));
app.use(express.bodyParser());
app.post('/Details/',function(request,response,next){
var keyName=request.query.Key;
console.log(keyName);
} );
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
Still have same error

Answer 1

Instead of query:
var keyName=request.query.Key;
console.log(keyName);
use body:
var keyName1=request.body.key;
console.log(keyName1);
Code:
var express = require('express')
, async = require('async')
, http = require('http');
var app = express();
app.set('port', process.env.PORT || 7002);
app.use(express.static(__dirname + '/public/images'));
app.use(express.bodyParser());
app.post('/Details/',function(request,response,next){
var keyName1=request.body.key;
console.log(keyName1);
} );
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});

Answer 2

var express = require('express');
var app = express();
app.use(express.bodyParser());
app.post('/post/', function(req, res) {
// print to console
console.log(req.body);
// just call res.end(), or show as string on web
res.send(JSON.stringify(req.body, null, 4));
});
app.listen(7002);

Answer 3

Use request.query when you have querystring params.
For form/post data use req.body.
In your case, use request.body.key.

Answer 4

An update on using the middleware, body-parser, for later versions of Express: Using app.use(express.bodyParser()) will report an error such as:
Error: Most middleware (like bodyParser) is no longer bundled with Express and must be installed separately. Please see https://github.com/senchalabs/connect#middleware.
This can be addressed by first installing the body-parser middleware:
npm install body-parser
then write code such as:
var bodyParser = require('body-parser');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
and then accessing the body of the request object, for example, console.log(req.body)

Answer 5

You can't call app.use(express.bodyParser()); inside middleware/route handler:
request should pass through bodyParser() before it reaches route handler
you will be adding new bodyParser()s in each request, but they will be after app.router and will never work

Use built in function "util" to print any type of json data in express js
var util = require("util");
console.log(util.inspect(myObject, {showHidden: false, depth: null}));
