node.js - ExpressJS AngularJS POST -

i'm learning angularjs , want know how correctly wire node expressjs.

this controller:

app.controller('view1ctrl', function($scope, $http) {      $scope.sub = function(desc) {         console.log(desc);         $http.post('/view1', desc).         then(function(response) {             console.log("posted successfully");         }).catch(function(response) {             console.error("error in posting");         })     } }); 

and server.js:

app.post('/view1', function(req, res) {     console.log(res.desc);     res.end(); }); 

i have not used body-parser. don't how body-parser used form values html when using function in controller. values got html on clicking submit when using body-parser or values got function on passing form values arguments. please tell me how done .

edit: html:

<form>       <input type="text" ng-model="desc" placeholder="enter desc" />       <button class="btn btn-primary" ng-click="sub(desc)">submit</button> </form> 

edit 2: full server.js code:

var express = require('express'),     http = require('http'),     path = require('path'),     bodyparser= require('body-parser');  var app = express();  app.set('port', 3000);  app.use(express.static(path.normalize(__dirname + '/'))); app.use(bodyparser.json()); // parsing application/json app.use(bodyparser.urlencoded({ extended: true })); // parsing       application/x-www-form-urlencoded  app.get('/main', function(req, res) {     var name = 'mynamefromserver';     res.send(name); });  app.post('/view1', function(req, res) {     console.log(res.body.desc);     res.end(); });  http.createserver(app).listen(app.get('port'), function() {     console.log('express server listening on port ' + app.get('port')); }); 

edit 3: edited controller app.js

app.controller('view1ctrl', function($scope, $http) {         $scope.sub = function() {         console.log($scope.formdata);         $http.post('/view1', $scope.formdata).         success(function(data) {             console.log("posted successfully");         }).error(function(data) {             console.error("error in posting");         })     }; }); 

the body-parser module node.js (express) can every data form post single object called req.body, if have $scope object define form data can inject directly have same properties copied on req.body:

angular:

app.controller('view1ctrl', function($scope, $http) {     $scope.sub = function() {         $http.post('/view1',$scope.formdata).         then(function(response) {             console.log("posted successfully");         }).catch(function(response) {             console.error("error in posting");         })     } }); 

html:

<form>       <input type="text" ng-model="formdata.desc" placeholder="enter desc" />       <input type="text" ng-model="formdata.title" placeholder="enter title" />       <button type="submit" class="btn btn-primary" ng-click="sub()">submit</button> </form> 

now when submit via $http.post('/view1', $scope.formdata)you same object, example:

app.post('/view1', function(req, res) {     console.log(req.body.desc);     res.end(); }); 

instead having ng-click on submit button, use ng-submitin form element this:

<form ng-submit="sub()">
