服务不会注入控制器

看到这个工作小提琴,

您将服务视为一个控制器,从不注入$scope服务,它不在那里

var myApp = angular.module('myApp',['myapp.services','myapp.controllers']);

angular.module('myapp.controllers', [])
.controller('StreamCtrl', ['$scope', 'StreamService',
function($scope, StreamService) {
    $scope.playlists = [1,2,3,4];
}]);

angular.module('myapp.services', []).factory('StreamService',  function() {
    var self = {
        'fetching' : false,
        'streamItems' : []
    };
    return self;}
);
