angular $ http post：无法获取请求参数

Question

I'm a beginner... creating a crud application with angular node and mysql

for some reason I can't get the data like console.log(request.body.name) or console.log(request.body.description) I get 505 error.. where as if I simply print console.log('any message') this gets displayed without any error.

I've this bind ng-click="editProductCategory()" on a button

bewlow is editProductCategory() method

$scope.editProductCategory = function (){

    productCategoryService.updateProductCategory($scope.productCategoryData, productCategoryService.getIdFromUri())
        .success(function (data) {
        if(data && data.status && data.status == 'successful'){
            alert('updated successfully');
        }
        })
        .error(function (err, status) {
        console.log('********************************');
        console.log(err);
        console.log('-------------------------------');
        console.log(status);
        console.log('********************************');
        });
    }

and here is my productCategoryService.updateProductCategory

updateProductCategory: function (productCategory, productCategoryId) {
            console.log(productCategory.name);
            console.log(productCategory.description);
            console.log(productCategoryId);
            return $http.post('/updateProductCategory', {
                name: productCategory.name,
                description: productCategory.description,
                categoryId: productCategoryId
            });

        }

Here is the route configuration

this.routeTable.push({
        requestType: 'post',
        requestUrl: '/updateProductCategory',
        callbackFunction: function(request, response)
        {
            console.log('/******* arrived successfully ********/');
            //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 will send your data as JSON, so if you are using Express, you need use the bodyParser middleware to parse the request body.

var express = require('express')
var app = express.createServer();

app.use(express.bodyParser());
