var factory = {};
var resoureurlBase=some base url;
factory.genericService = function(method, payload, methodName, callbackFn, callbackError, param) {
var httpRequest = null;
if (param && param == true) {
httpRequest = $http({
url: resoureurlBase+methodName,
method: method,
params: payload,
headers: {

Answer 1

Simple DI(dependency injection) it into your controller:-
myapp.controller('myCtrl',['$scope','serviceName',function($scope,serviceName){
// use serviceName to call your factory function
}]);

You need to call service like
serviceName.genericService(--parmas--).then(function(d){
//success
})
because from service serviceName, you're returning a promise that need to resolved using .then only.
Controller
var mainController = function($scope, serviceName) {
var callbackFn = function() {
console.log('Success');
}
var callbackError = function() {
console.log('Error');
}
var parameter = {
param1: 1
},
method = 'something', payload = 100, methodName = 'something';
serviceName.genericService(method, payload, methodName, callbackFn, callbackError, parameter).then(
//success function
function(data) {
//call after call succeed
},
//error function
function(error) {
//call after call error
});
};
myapp.controller('mainController', ['$scope', 'serviceName', mainController()];
Hope this could help you. Thanks.
