控制器未定义
Controller is undefined
提前感谢您的帮助。我是Angular的新手，对Javascript有点陌生，我遇到了一个问题，我似乎无法解决。
由于某些原因，WebStorm告诉我导入的控制器没有定义。我是从另一个文件中引用的，这个文件已经导入了。我正在尝试使用Spotify API与angular-js web包装器。

模块和应用程序都定义得很好，但是正文中的这些脚本标记是错误的部分。Angular不支持命令式编程。
你的主体应该使用绑定来访问控制器的$scope成员。
像这样:
<body ng-controller='test'>
<div ng-repeat="artist in artists">
{{artist|json}}
</div>
</body>
ajax请求完成后，应该自动显示数据，或者相反，如果发生错误，您可以在浏览器的开发人员控制台中找到更多详细信息。
同时，控制器作用域没有称为getAlbum的方法。
所以要解决这些问题:(假设不再需要登录工作流)
添加一个加载专辑数据的控制器方法，并从控制器本身或从另一个指令(如ng-click)调用它:
// inside the main controller
$scope.loadData = function () {
Spotify.getAlbum('your album Id').then(function (data) {
$scope.albumInfo = data;
});
};
// call the function here or in a ng-click for instance.
$scope.loadData();
用绑定呈现数据:(在本例中格式为json)
<html ng-app="app">
<body ng-controller="test">
<pre>{{albumInfo | json}}</pre>
</body>
注意，HTML被简化了，你必须加载angular, main。
