如何使用 Angular UI-Router 使用未经验证的电子邮件重定向用户?

问题描述

我正在将 AngularJS 与 Meteor 结合使用，并希望将使用未经验证的电子邮件的用户重定向到登录页面.我在 /client/routes.js 中创建了一个登录视图:

I am using AngularJS with Meteor and wanted to redirect users with unverified emails to the sign in page. I have created a sign in view in /client/routes.js:

app.config(['$stateProvider', '$urlRouterProvider',
function($stateProvider, $urlRouterProvider){
  $urlRouterProvider.otherwise('/');

  $stateProvider

  .state('signin', {
    url:'/signin',
    views: {
      main: {
        templateUrl: 'client/views/profile/signin.tpl'
      }
    }
  })

请注意，为了简洁起见，我没有列出其他州.

Note that there are other states I am not listing for brevity sake.

现在，如果用户的电子邮件未经验证，我想将用户重定向到此登录页面.如何从 UI-Router FAQs 来满足我的需求?我可以接受不使用以下示例的其他解决方案，只要它们能解决手头的问题.

Now, I want to redirect users to this sign in page if their emails have not been verified. How do I modify the example below from UI-Router FAQs to meet my needs? Other solutions not using the example below are acceptable to me as long as they address the issue at hand.

示例:使用状态配置上的数据对象来定义规则将针对用户运行逻辑的函数(此处使用示例名为 $currentUser 的服务).$stateChangeStart 处理程序捕获所有状态转换并在允许之前执行此规则检查转换，可能会阻止它和/或重定向到不同的状态.

app.config(function($stateProvider) {
  $stateProvider.state('privatePage', {
    data: {
      rule: function(user) {
        // ...
      }
  });
});
app.run(function($rootScope, $state, $currentUser) {
  $rootScope.$on('$stateChangeStart', function(e, to) {
    if (!angular.isFunction(to.data.rule)) return;
    var result = to.data.rule($currentUser);

    if (result && result.to) {
      e.preventDefault();
      // Optionally set option.notify to false if you don't want
      // to retrigger another $stateChangeStart event
      $state.go(result.to, result.params, {notify: false});
    }
  });
});

推荐答案

FAQ 中的示例尝试创建一种向任何页面添加规则的通用方法.让我们保持简单:

The example from the FAQ attempts to create a general way to add a rule to any page. Let's keep it simple:

app.run(function($rootScope, $state, UserService) {
    $rootScope.$on('$stateChangeStart', function(event, toState) {
        // don't check auth on login routes
        if (["signin"].indexOf(toState.name) === -1) {
            if (UserService.doesNotHaveVerifiedEmail()) {
                event.preventDefault();
                $state.go('signin');
                return;
            }
        }
    }
});

任何时候加载状态并且它不是 signin 状态，您检查用户是否已验证(取决于您的应用程序，这里我注入一个 UserService，我假设它了解用户的状态) 否则，您可以阻止该状态更改并将其重定向到登录页面.

Anytime a state is loaded and it's not the signin state, you check if the user is verified (depends on your application, here I am injecting a UserService which I assume has knowledge about the user's status) and if not, you prevent that state change and redirect them to the signin page.
