AngularJS登录后如何重定向到下一个路由

app = angular.module('ngApp',[]).config(function ($routeProvider) {
  $routeProvider
    .when('/dashboard',{
        templateUrl: 'dashboard.html',controller: 'dashboardController',loginRequired: true //
      })
    .when('/login',{
        templateUrl: 'login.html',controller: 'loginController'
      })
    .otherwise({redirectTo: '/login'})
});

然后在应用程序的运行块中：

app.run(function ($location,$rootScope) {
    var postLogInRoute;

    $rootScope.$on('$routeChangeStart',function (event,nextRoute,currentRoute) {

    //if login required and you're logged out,capture the current path
        if (nextRoute.loginRequired && Account.loggedOut()) {
          postLogInRoute = $location.path();
          $location.path('/login').replace();
        } else if (postLogInRoute && Account.loggedIn()) {
    //once logged in,redirect to the last route and reset it
          $location.path(postLogInRoute).replace();
          postLogInRoute = null;
        }
    });
});
