Angularjs $rootScope，带TypeScript和controllerAs

我正在用Angular 1和Typescript构建一个应用程序。下面是我的登录控制器

module TheHub {
    /**
     * Login page controller.
     */
    export class LoginController {

        static $inject = ['$http', '$rootScope', '$location'];

        constructor(private $http: ng.IHttpService, private $rootScope, private $location: ng.ILocationService) {

        }

        /**
         * Method to check if the user is logged in 
         */
        login(user: {}) {
            this.$http.post('/login', user).then((value: ng.IHttpPromiseCallbackArg<{}>) => {
                this.$rootScope.auth = { isAuthenticated: true, isAuthenticationChecked: true };
                this.$location.url('/');
            }, (error: any) => {
                this.$rootScope.auth = { isAuthenticated: false, isAuthenticationChecked: true };
            });
        }
    }

    angular.module('TheHub').controller('LoginController', LoginController);
}

视图：

<div id="sideNavContainer" ng-controller="AppController as ctrl" layout="column" ng-cloak layout-fill>
    <md-toolbar flex="none">
        <div class="md-toolbar-tools">
            <md-button class="md-icon-button" aria-label="Settings" hide-gt-md ng-click="ctrl.openLeftMenu()">
                <i class="material-icons">menu</i>
            </md-button>
            The Hub
            <span flex></span>
        </div>
    </md-toolbar>
    <md-content flex layout="row">
        <md-sidenav ng-show="ctrl.auth.isAuthenticated" class="md-sidenav-left" md-component-id="left" md-is-locked-open="$mdMedia('gt-md')" md-disable-backdrop md-whiteframe="4" flex="none">
            <md-content layout-padding>

            </md-content>
        </md-sidenav>
        <div ng-view flex="grow"></div>

    </md-content>
</div>

枢纽

视图在

ctrl.auth

中查找

auth

对象。因此它希望它是

AppController

的一个属性。但事实并非如此。它是

$rootScope

的一个属性。因为每个表达式都在作用域上求值，并且每个作用域都继承自$rootScope，所以您只需要

ng-show="auth.isAuthenticated"

---

如果看不到应用程序控制器及其视图，就很难诊断问题。

ng-show="auth.isAuthenticated"
