javascript - 调用模块常量？

Question

我有以下 Angular 模块。我如何从我的 Controller 之一调用 APIHost？

angular.module('configuration', [])
    .constant('APIHost','http://api.com')
    .constant('HostUrl','http://example.com')
    .constant('SolutionName', 'MySite');

Constant只不过是一种提供者配方。

您需要在controller工厂函数中注入(inject)constant依赖项，就是这样。

app.controller('testCtrl', function($scope, APIHost){
  console.log(APIHost)
})

Make sure your configuration module has been added to main module as dependency to get use of constant's provider like below

var app = angular.module('app', ['configuration', 'otherdependency']);
app.controller( ... ) //here you can have configuration constant available
