javascript - Angular JS注入(inject)器模块错误

Question

我是 Angular JS 的新手，我正在尝试在配置中注入(inject)工厂，但它显示找不到模块

工厂代码

var app=angular.module('app',['ui.router','angular-jwt','ngResource','angularValidator','satellizer']);

app.factory('AUTH_SERVICE', function ($auth,$state,$q) {
    var auth={};

 auth.isloggedin=function() {
     var defer = $q.defer();
    if($auth.isAuthenticated()){
   defer.resolve();
    }
    else
    {      
  $state.go('login');  
   defer.reject();     
    }

    return defer.promise;
}

 return auth;
});

配置代码是

app.config(['AUTH_SERVICE','$authProvider','$stateProvider', '$urlRouterProvider',function(AUTH_SERVICE,$stateProvider, $urlRouterProvider,$authProvider) {
$urlRouterProvider.otherwise('/');
    $stateProvider
    .state('home',{
        url:'/',
        templateUrl:'pages/home.html'

})
.state('login',{
    url:'/login',
    templateUrl:'pages/login.html',
    controller:'loginCtrl'
})
.state('register',{
    url:'/register',
    templateUrl:'pages/register.html',
    controller:'registerCtrl'

})

.state('dashboard',{
    url:'/Dashboard',
    templateUrl:'pages/dashboard.html',
    controller:'dashctrl',
    resolve:{
        skiplogin: _skiplogin
    }
})

function _skiplogin(AUTH_SERVICE){
return AUTH_SERVICEAUTH_SERVICE.isloggedin();
}



 }]);

但是显示错误

angular.js:38Uncaught Error: [$injector:modulerr] http://errors.angularjs.org/1.5.8/$injector/modulerr?p0=app&p1=Error%3A%20%…ocalhost%2Faccoex%2Fbower_components%2Fangular%2Fangular.min.js%3A39%3A319)

Answer 1

您无法在 app.config 中注入(inject) factory 对象，因为它无法确定它们是否已正确加载。

在app.config中，您只能注入(inject)Consts和Providers。

来自文档

A module is a collection of configuration and run blocks which get applied to the application during the bootstrap process. In its simplest form the module consist of collection of two kinds of blocks:

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.

Run blocks - get executed after the injector is created and are used to kickstart the application. Only instances and constants can be injected into run blocks. This is to prevent further system configuration during application run time.

查看 provider here您可以在 app.config 中配置服务。
