Processing $http response in service

Question

I recently posted a detailed description of the issue I am facing here at SO. As I couldn\'t send an actual $http request, I used timeout to simulate asynchrono

Please try the below Code

You can split the controller (PageCtrl) and service (dataService)

'use strict';
(function () {
    angular.module('myApp')
        .controller('pageContl', ['$scope', 'dataService', PageContl])
        .service('dataService', ['$q', '$http', DataService]);
    function DataService($q, $http){
        this.$q = $q;
        this.$http = $http;
        //... blob blob 
    }
    DataService.prototype = {
        getSearchData: function () {
            var deferred = this.$q.defer(); //initiating promise
            this.$http({
                method: 'POST',//GET
                url: 'test.json',
                headers: { 'Content-Type': 'application/json' }
            }).then(function(result) {
                deferred.resolve(result.data);
            },function (error) {
                deferred.reject(error);
            });
            return deferred.promise;
        },
        getABCDATA: function () {

        }
    };
    function PageContl($scope, dataService) {
        this.$scope = $scope;
        this.dataService = dataService; //injecting service Dependency in ctrl
        this.pageData = {}; //or [];
    }
    PageContl.prototype = {
         searchData: function () {
             var self = this; //we can't access 'this' of parent fn from callback or inner function, that's why assigning in temp variable
             this.dataService.getSearchData().then(function (data) {
                 self.searchData = data;
             });
         }
    }
}());
