限时送ChatGPT账号..

我正在尝试在我的 angular 应用程序上实现授权，当路由更改时，我想检查该路由是否已为用户授权.我尝试使用 $routeChangeStart 但它不会阻止该事件.

I am trying to implement Authorization on my angular application, when a route is changed I want to check whether the route is authorized for user or not. I tried with $routeChangeStart but it does not prevents the event.

我当前的代码:

$scope.$on('$routeChangeStart', function(event, next, current) {
        if(current_user.is_logged_in){
            var route_object = next.route_object;
            if(!(route_object.route_roles)){
                event.preventDefault();
            }
        }
    });

在我的 next 对象中，我得到了在 $routeProvider

Here in my next object I am getting route_object which is set in my $routeProvider

var routes = object;
    app.config(function($routeProvider) {
                $routeProvider.when(url, {
                    templateUrl: "/users.html",
                    route_object: routes,
                    });
            });

routes 是在我的函数中形成的对象，但是当我使用 $locationChangeStart 时，我只是获取下一页和上一页的 url，

routes is an object which is formed in my function, but when I use $locationChangeStart I am just getting url's of next and previous page,

如何获取整个路由对象??

How do I get the entire route object??

推荐答案

您可以像这样在 $locationChangeStart 事件侦听器中获取路由参数:

You can get the route parameter in an $locationChangeStart event listener like this:

$scope.$on('$locationChangeStart', function(event, next, current) {
    if(current_user.is_logged_in){
        var route_object = ($route.routes[$location.path()]).route_object; //This is how you get it
        if(!(route_object.route_roles)){
            event.preventDefault();
        }
    }
});

然后经典的 preventDefault 方法将完成这项工作.这是我为类似内容编写的 plunker.

Then classic preventDefault method would do the work. Here's a plunker that I wrote for something similar.
