即使在将依赖项添加到 ngResource 之后 $resource 错误

Question

我正在尝试使用来自 mongolab 的 $resource 在 angular 应用程序中显示数据。我在模块中添加了对 ngResource 的依赖。仍然显示未知提供商。这里缺少什么？

'$resource is not defined'

注意：当我的工厂名称不正确时，我得到错误：Unknown provider: employeesProvider <- employees

代码

<html>
<head>

<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular-resource.js"></script>

<script type="text/javascript">

 //defining module
 var app = angular.module('myApp', ['ngResource']);

 //defining factory
 app.factory('employees', function () {

    return $resource('https://api.mlab.com/api/1/databases/humanresource/collections/Employees',
                    {apiKey: 'removedmykeyforpostinginSO'}
                  );
 });

 //defining controller
 app.controller('myController', function ($scope, employees) 
 {
    $scope.countries = employees.query();
 });  

</script>
</head>

<body ng-app="myApp">
     <div ng-controller="myController">
    <ul>
        <li ng-repeat = "objCountry in countries" >
            {{objCountry.name}}

        </li>
    </ul>
     </div>
</body>
</html>

JSON 来自 Mongolab

[ { "_id" : { "$oid" : "57044f95e4b0427faa38585f"} , "name" : "Lijo" , "age" : "30"} ]

从AngulaJS Documentation开始，推荐的声明工厂的方式是：

angular.module('myModule', [])
.factory('serviceId', ['depService', function(depService) {
  // ...
}])

我通过注入 $resource 更正了我的工厂代码如下：

app.factory('employees', function ($resource) {

    return $resource('https://api.mlab.com/api/1/databases/humanresource/collections/Employees',
                    {apiKey: 'jJbAltZ26vuIrgzUQetXh480JM0q9k6p'}
                  );
 });
