java script code for injecting service into controller
var myApp = angular
.module('myApp', [ 'ngRoute'])
myApp.factory('UserService',['ngResource', function($resource) {
return $resource('/login', {}, {
login : {
method : 'POST',
params : {
'action' : 'authenticate'
},
headers : {
'Content-Type' : 'application/x-www-form-urlencoded'
}
},
});
}]);
myApp.config([ '$routeProvider', '$locationProvider', '$httpProvider','$provide',
function($routeProvider, $locationProvider, $httpProvider,$provide) {
$routeProvider
// route for the home page
.when('/', {
templateUrl : 'pages/login.html',
controller : 'mainController'
})
// route for the about page
.when('/dashbaord', {
templateUrl : 'pages/dashboard.html',
controller : 'dashbaordController'
})
$locationProvider.hashPrefix('!');
} ]);
myApp.controller('mainController',['UserService',function($scope,UserService) {
function login() {
alert("hi");
}
$scope.login = login;
}]);
myApp.controller('dashbaordController', function($scope) {
$scope.message = 'Look! I am an about page.';
});
javascript code for injecting in config , it is same code below i have copied the only changed code
myApp.config([ '$routeProvider', '$locationProvider', '$httpProvider','$provide','UserService',
function($routeProvider, $locationProvider, $httpProvider,$provide,UserService) {
$routeProvider
// route for the home page
.when('/', {
templateUrl : 'pages/login.html',
controller : 'mainController'
})
// route for the about page
.when('/dashbaord', {
templateUrl : 'pages/dashboard.html',
controller : 'dashbaordController'
})
$locationProvider.hashPrefix('!');
} ]);
Please include the "angular-resource.js" if you are using ngResource. You can find the cdn in the following link, Angular ngResource api doc
You can only inject provider in .config. Try to transform you UserService into a provider instead of a factory
UserSerivce is a service so you can not inject it like a provider. You did not need to inject service into app.config. you can simply use it by injecting in controller.
