Question

刚刚接触angularjs并且一直在寻找让应用程序运行的方法。非常简单直接：

角度控制器：

(function () {
    'use strict';

    angular
        .module('myQuotesApp')
        .controller('QuotesController', QuotesController);

    QuotesController.$inject = ['$scope', 'Quotes']; 

    function QuotesController($scope, Quotes) {
        $scope.quotes = Quotes.query();
    }
})();

这是angularjs的服务类

(function () {
    'use strict';
    var QuotesService = angular.module('QuotesService', '[ngResource]');
    QuotesService.factory('Quotes', ['$resource', function ($resource) {
        return $resource('/api/quotes/', {}, {
            query: { method: 'GET', params: {}, isArray:true }
        });
    }]);
})();

这是html文件：

<!DOCTYPE html>
<html ng-app="myQuotesApp">
<head>
    <meta charset="utf-8" />
    <title>My Quotes App</title>
    <script src="lib/angular/angular.min.js"></script>
    <script src="lib/angular-resource/angular-resource.min.js"></script>
    <script src="lib/angular-route/angular-route.min.js"></script>
    <script src="/app.js"></script>
</head>
<body ng-cloak>
    <div ng-controller="QuotesController">
        <H2>List of Quotes</H2>
        <ul>
            <li ng-repeat="quote in quotes">
                <p> "{{quote.Content}}" - {{quote.Author}}</p>
            </li>
        </ul>
    </div>
</body>
</html>

服务器端模型：

public class Quote
    {
        public int Id { get; set; }
        public string Author { get; set; }
        public string Comment { get; set; }
    }

服务器端控制器：

public IEnumerable<Quote> Get()
        {
            return new List<Quote> {
                new Quote { Id=1, Author="James John",       Comment="This guy is good to work with."},
                new Quote { Id=2, Author="Larry Page",       Comment="This is one of the best guys in the IT world"},
                new Quote { Id=3, Author="Goodwill Adebayo", Comment="It is always good to work with God." }
            };
        }

每当我运行应用程序时，它都会显示一个空白页面。我检查了浏览器控制台，我收到了这个错误：

angular.js:4640Uncaught Error: [$injector:modulerr] http://errors.angularjs.org/1.5.8/$injector/modulerr?p0=myQuotesApp&p1=Erro…http%3A%2F%2Flocalhost%3A60261%2Flib%2Fangular%2Fangular.min.js%3A20%3A390)
jquery-1.9.0.js:1 '//@ sourceURL' and '//@ sourceMappingURL' are deprecated, please use '//# sourceURL=' and '//# sourceMappingURL=' instead.

你缺少一些东西。在使用之前，您需要先创建 myQuotesApp 模块。

Plunker的工作示例 - http://plnkr.co/edit/l3UmoDjjGhaQq0JNjtsF。

(function () {
    'use strict';

    angular
      .module('myQuotesApp', ['ngResource']) // <----
      .controller('QuotesController', QuotesController);

    QuotesController.$inject = ['$scope', 'QuotesService']; 

    function QuotesController($scope, QuotesService) {
        $scope.quotes = QuotesService.query();
    }

    angular
      .module('myQuotesApp')
      .factory('QuotesService', ['$resource', function ($resource) {
        var query = function() {
          return [{Content: "One", Author: "John"}, 
            {Content: "Two", Author: "Eric"}]
        }
        return {
          query: query 
        }
    }]);
})();

如何从Web API中提取数据

您只需要更新QuotesService以使用$ resource。

(function () {
    'use strict';

    angular
        .module('myQuotesApp', ['ngResource'])
        .controller('QuotesController', QuotesController);

    QuotesController.$inject = ['$scope', 'QuotesService'];

    function QuotesController($scope, QuotesService) {
        $scope.quotes = QuotesService.query();
        console.log($scope.quotes);
    }

    angular
        .module('myQuotesApp')
        .factory('QuotesService', ['$resource', function ($resource) {
            return $resource('/api/quotes/', {}, {
                query: { method: 'GET', params: {}, isArray: true }
            });
        }]);
})();

错误：$ injector：modulerr模块错误
