here route configuration

this.routetable.push({         requesttype: 'post',         requesturl: '/updateproductcategory',         callbackfunction: function(request, response)         {             console.log('/******* arrived ********/');             //console.log(request.body.description + " no errors");             //console.log(request.param());              response.json()         }     });  this.routetable.foreach(function(route){         if(route.requesttype == 'get')         {             this.app.get(route.requesturl, route.callbackfunction)         }         else if(route.requesttype == 'post' || route.requesttype == 'post   ')         {             this.app.post(route.requesturl, route.callbackfunction);         }         else if(route.requesttype == 'delete'){}     }); 

any idea?

$http.post send data json, if using express, need use bodyparser middleware parse request body.

var express = require('express') var app = express.createserver();  app.use(express.bodyparser());
