Angular2条件路由 [英] Angular2 conditional routing

问题描述

这可能是一个基本问题，但是在Angular2中，有什么方法可以进行条件路由吗?或者，有人会在路由器外执行此操作吗?

This might be a basic question, but in Angular2 is there any way to do conditional routing ? Or, would someone do that outside the router ?

我知道ui-router可以做到这一点，但是我在Angular2s路由器中没有看到类似的东西

I know ui-router had some ability to do this, but I haven't seen anything similar in Angular2s router

推荐答案

更新

在新路由器中可以使用防护装置来代替 https://angular.io/guide/router#milestone-5-route-警卫队

In the new router guards can be used instead https://angular.io/guide/router#milestone-5-route-guards

原始(用于已久的路由器)

original (for the long gone router)

实施CanActivate生命周期挂钩，如下所示生命周期挂钩在Angular2路由器中，如果要阻止导航，则返回false. 另请参见 https://angular.io/docs/ts/Latest/api/router/CanActivate-var.html

Implement the CanActivate lifecycle hook like shown here Life cycle hooks in Angular2 router and return false if you want to prevent the navigation. See also https://angular.io/docs/ts/latest/api/router/CanActivate-var.html
