如何在angularJS中执行routeGuard

var app = angular.module('myApp', ['ngRoute']);

app.config(function($routeProvider) {
  $routeProvider
    .when('/dashboard', {
      templateUrl: 'dashboard.html',
      controller: 'DashboardController',
      resolve: {
        auth: function(AuthService) {
          // 在这里执行routeGuard逻辑，例如验证用户身份
          return AuthService.isAuthenticated();
        }
      }
    })
    .when('/profile', {
      templateUrl: 'profile.html',
      controller: 'ProfileController',
      resolve: {
        auth: function(AuthService) {
          // 在这里执行routeGuard逻辑，例如检查用户权限
          return AuthService.hasPermission('profile');
        }
      }
    })
    .otherwise({
      redirectTo: '/dashboard'
    });
});

app.controller('DashboardController', function($scope) {
  // 控制器逻辑
});

app.controller('ProfileController', function($scope) {
  // 控制器逻辑
});
