我正在 Ionic 中构建一个应用程序，并开始深入研究 Firebase 身份验证方法。到目前为止，我已经成功地通过 Twitter 正确设置了登录（我可以登录和注销）。
但是，如何设置 ionic 框架的状态，以便在登录时仅显示特定状态（以及页面），在注销时显示其他状态？到目前为止我的代码如下所示。
理想情况下，我会有一个类似变量的东西：
AuthRequired: true
你如何做到这一点以及它叫什么？
app.js
// Ionic Starter App
// angular.module is a global place for creating, registering and retrieving Angular modules
// 'starter' is the name of this angular module example (also set in a <body> attribute in index.html)
// the 2nd parameter is an array of 'requires'
// 'starter.services' is found in services.js
// 'starter.controllers' is found in controllers.js
angular.module('starter', ['ionic', 'ngCordova', 'firebase', 'firebase.utils', 'starter.controllers', 'starter.services', 'starter.config', 'starter.auth'])
.run(function($ionicPlatform, Auth, $rootScope) {
$ionicPlatform.ready(function() {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
if (window.cordova && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
}
if (window.StatusBar) {
// org.apache.cordova.statusbar required
StatusBar.styleDefault();
}
});
//stateChange event
$rootScope.$on("$stateChangeStart", function(event, toState, toParams, fromState, fromParams){
if (toState.authRequired && !Auth.isAuthenticated()){ //Assuming the AuthService holds authentication logic
// User isn’t authenticated
$state.transitionTo("login");
event.preventDefault();
}
});
})
.config(function($stateProvider, $urlRouterProvider) {
// Ionic uses AngularUI Router which uses the concept of states
// Learn more here: https://github.com/angular-ui/ui-router
// Set up the various states which the app can be in.
// Each state's controller can be found in controllers.js
$stateProvider
// setup an abstract state for the tabs directive
.state('tab', {
url: "/tab",
abstract: true,
templateUrl: "templates/tabs.html"
})
// Each tab has its own nav history stack:
.state('tab.dash', {
url: '/dash',
views: {
'tab-dash': {
templateUrl: 'templates/tab-dash.html',
controller: 'DashCtrl',
authRequired: true
},
}
})
.state('tab.chats', {
url: '/chats',
views: {
'tab-chats': {
templateUrl: 'templates/tab-chats.html',
controller: 'ChatsCtrl',
authRequired: true
}
}
})
.state('tab.chat-detail', {
url: '/chats/:chatId',
views: {
'tab-chats': {
templateUrl: 'templates/chat-detail.html',
controller: 'ChatDetailCtrl',
authRequired: true
}
}
})
.state('tab.friends', {
url: '/friends',
views: {
'tab-friends': {
templateUrl: 'templates/tab-friends.html',
controller: 'FriendsCtrl',
authRequired: true
}
}
})
.state('tab.friend-detail', {
url: '/friend/:friendId',
views: {
'tab-friends': {
templateUrl: 'templates/friend-detail.html',
controller: 'FriendDetailCtrl',
authRequired: true
}
}
})
.state('tab.account', {
url: '/account',
views: {
'tab-account': {
templateUrl: 'templates/tab-account.html',
controller: 'AccountCtrl',
authRequired: true
}
}
})
.state('tab.example', {
url: '/example',
views: {
'tab-example': {
templateUrl: 'templates/tab-example.html',
controller: 'ExampleCtrl',
authRequired: true
}
}
})
.state('tab.overview', {
url: '/overview',
views: {
'tab-overview': {
templateUrl: 'templates/tab-overview.html',
controller: 'OverviewCtrl',
authRequired: true
}
}
})
.state('tab.login', {
url: '/login',
views: {
'tab-login': {
templateUrl: 'templates/tab-login.html',
controller: 'LoginCtrl',
authRequired: true
}
}
});
// if none of the above states are matched, use this as the fallback
$urlRouterProvider.otherwise('/tab/dash');
})
