Angular2 NavigationEnd事件的类型“事件”上不存在属性“ URL” [英] Property 'url' does not exist on type 'Event' for Angular2 NavigationEnd Event

问题描述

    this.subscription = this.router.events.subscribe((event:Event) => {
        console.log(event.url); ##### Error : Property 'url' does not exist on type 'Event'.
   }

Typescript无法识别Angular Router内置的Event类型的属性。tsd上有什么我可以用来解决的问题吗？Event是NaviagationEnd，NavigationStart类的超类

Typescript doesn't recognize the properties of the type Event that is built into the Angular Router. Is there something on tsd that I can use to solve this? Event is the super class of classes NaviagationEnd, NavigationStart

推荐答案

您必须从@ angular / router导入{Event}； 尝试将控制台移至 if 有条件的块。

You have to import { Event } from @angular/router;. Try moving console into the if block with condition.

this.subscription = this.router.events.subscribe((event:Event) => {
  if(event instanceof NavigationEnd ){
    console.log(event.url);
  }
});
