Javascript AngularJS从nodejs API获取JSON

我有个奇怪的问题。 我的nodejsapi与mongodb一起工作。 Angular正在通过JSON从nodejs请求数据。 我使用Webstorm 11启动Angular应用程序。 那么，我使用这个JSON执行ng repeat，得到以下结果：

    TypeError: Cannot read property '$id' of undefined
    at arguments.(anonymous function) (chrome-extension://ighdmehidhipcmcojjgiloacoafjmpfk/dist/hint.js:2001:19)
    at m.$digest (https://code.angularjs.org/1.5.0/angular.min.js:138:399)
    at m.scopePrototype.$digest (chrome-extension://ighdmehidhipcmcojjgiloacoafjmpfk/dist/hint.js:2016:23)
    at m.$apply (https://code.angularjs.org/1.5.0/angular.min.js:141:341)
    at m.scopePrototype.$apply (chrome-extension://ighdmehidhipcmcojjgiloacoafjmpfk/dist/hint.js:2079:22)
    at https://code.angularjs.org/1.5.0/angular.min.js:21:44
        at Object.invoke (https://code.angularjs.org/1.5.0/angular.min.js:41:295)

    at Object.Ac.ia.resumeBootstrap (https://code.angularjs.org/1.5.0/angular.min.js:21:357)
    at maybeBootstrap (chrome-extension://ighdmehidhipcmcojjgiloacoafjmpfk/dist/hint.js:569:11)

这是：

    TypeError: Cannot read property '$id' of undefined
    at arguments.(anonymous function) (chrome-extension://ighdmehidhipcmcojjgiloacoafjmpfk/dist/hint.js:2001:19)
    at m.$digest (https://code.angularjs.org/1.5.0/angular.min.js:138:399)
    at m.scopePrototype.$digest (chrome-extension://ighdmehidhipcmcojjgiloacoafjmpfk/dist/hint.js:2016:23)
    at m.$apply (https://code.angularjs.org/1.5.0/angular.min.js:141:341)
    at m.scopePrototype.$apply (chrome-extension://ighdmehidhipcmcojjgiloacoafjmpfk/dist/hint.js:2079:22)
    at g (https://code.angularjs.org/1.5.0/angular.min.js:94:139)
    at t (https://code.angularjs.org/1.5.0/angular.min.js:98:260)
    at XMLHttpRequest.u.onload (https://code.angularjs.org/1.5.0/angular.min.js:99:297)

对于ng中的每个元素，请重复。 结果页面工作正常，但控制台中的此错误不好

然后我尝试使用这个JSON：

使用此JSON不会引发任何错误。。 这就是我如何认识到我的JSON不够好的原因：D也许我需要放一些标题？在所附图片中，您可以比较我使用的JSON

p、 还有一件奇怪的事：当我在没有webstorm的浏览器中执行index.html文件时(file:///Users/rustem/Dropbox/octomoney/index.html)-控制台中没有错误，应用程序工作正常

JSON的：

            .error(function (err) {
                return err;
            });
    }]);

如何使用ng重复：

    <body ng-app="octomoney">
    <div>
        <div ng-controller="getExpensesController">
            <div ng-repeat="expense in expenses.data" align="center">
                <h4>{{ expense.name }}</h4>
            </div>
        </div>
    </div>

    <script src="js/controllers/mainController.js"></script>
    <script src="js/services/getExpensesService.js"></script>
    </body>

发现是AngularJS Batarnang造成了这个问题

此处的详细信息：

我没有看到附加图片。将执行ng repeat的HTML链接到我们这里，这是json文件的一部分，用于检查dara格式，以及如何将其加载到控制器中此错误背后的原因是…您已在getExpensesController中注入GetExpenseService，但未在angular.module（'octomoney'，[]）中添加ExpensService模块@巴尼克：不，没有帮助。再说一次，使用另一个JSON可以很好地工作（没有错误）。@Waltrat，对不起，这个问题。
