angularjs - 当 .module 定义中包含 localStorage 时，为什么我不能在 .config 中使用它？

Question

我有以下内容:

var app = angular
    .module('app', ['ui.router', 'admin', 'home', 'questions', 'ngResource', 'LocalStorageModule'])
    .config(['$sceProvider', '$stateProvider', '$locationProvider', 'localStorageService',
        function ($sceProvider, $stateProvider, $locationProvider, localStorageService ) {

        $sceProvider.enabled(false);
        $locationProvider.html5Mode(true);

        localStorageService.add('adminContent', 'xx');

这给了我一个错误:

Uncaught Error: [$injector:modulerr] Failed to instantiate module app due to:

不能像这样在配置中使用 localStorage 吗？我已经包含了 localstorage 模块的代码，它是在 app.js 之前加载的。它适用于应用程序的其他部分，但同一行放在 app.config 中时不起作用

只有提供者和常量可以注入(inject)到配置 block 中。请参阅 AngularJs 文档了解更多信息:http://docs.angularjs.org/guide/module (sektion“模块加载和依赖”)。

Configuration blocks - get executed during the provider registrations and configuration phase. Only providers and constants can be injected into configuration blocks. This is to prevent accidental instantiation of services before they have been fully configured.
