创建工厂后无数据显示

问题内容：

这是我学习AngularJS的第二天。我有一个我无法解决的问题。一切顺利，直到我创建了工厂。我了解工厂/服务用于重构代码。因此，我从控制器中获取了一些代码，并将其发送到工厂，以便可以加载一些数据，但是事实并非如此。这些是我的代码：

index.html

(function() {
    var customerFactory = function() {
        var customers = [
          { 
            id: 1,
            joined: '2005-09-07', 
            name: 'Mayweather', 
            city: 'Brooklyn', 
            orderTotal: '43.1299',
            orders: [
              {
                id: 1,
                product: 'Pencils',
                total: 9.9956
              }
            ]

          }, 
          {
            id: 2,
            joined: '2005-09-07', 
            name: 'Jason', 
            city: 'Cleveland', 
            orderTotal: '89.8933',
            orders: [
              {
                id: 1,
                product: 'iPad',
                total: 20.9956
              }
            ]  
          }, 
          {
            id: 3,
            joined: '1999-08-27', 
            name: 'Jade', 
            city: 'Wroclaw', 
            orderTotal: '77.0092',
            orders: [
              {
                id: 1,
                product: 'Pillows',
                total: 12.2311
              }
            ]
          }, 
          {
            id: 4,
            joined: '2015-09-01', 
            name: 'David', 
            city: 'Accra', 
            orderTotal: '13.8465',
            orders: [
              {
                id: 1,
                product: 'Serek',
                total: 11.4782
              }
            ]
          }, 
          {
            id: 5,
            joined: '2001-01-18', 
            name: 'Doyet',
            city: 'Paris',
            orderTotal: '23.9930',
            orders: [
              {

                product: 'Serek',
                total: 11.4782
              }
            ]
          }];

            //Defind factory object
            var factory = {};

            factory.getCustomers = function() {
                return customers;
            };

            return factory;

    };

            angular.module('myApp').factory('customerFactory', customerFactory);
}());

                templateUrl: 'app/views/orders.html'
            })

              {
                id: 1,
                product: 'Serek',
                total: 11.4782
              }
            ]
          }];

            //Defind factory object
            var factory = {};

            factory.getCustomers = function() {
                return customers;
            };

            return factory;

    };

            angular.module('myApp').factory('customerFactory', customerFactory);
}());

在Chrome的控制台中，我知道该customers.html文件未加载。我该如何解决？

编辑：

我安装了“ http-server”，现在得到以下信息：

安慰：

这意味着我的代码有问题。有人可以指出我的方向吗？为什么我的“提供者”未知？

问题答案：

我建议http-server作为一种快速简便的解决方案来运行您的应用程序，并帮助解决您的文件加载问题：

https://www.npmjs.com/package/http-
server
