如果你试图访问当前路由，同时监听路由变化:

router.events.pipe(filter(r=>r instanceof NavigationEnd)).subscribe(r=>{
      console.log((r as NavigationEnd).url);
    });

在angular 6和RxJS6中:

import { filter, debounceTime } from 'rxjs/operators';

 this.router.events.pipe(
      filter((event) => event instanceof NavigationEnd),
      debounceTime(40000)
    ).subscribe(
      x => {
      console.log('val',x);
      this.router.navigate(['/']); /*Redirect to Home*/
}
)

更清晰的方法是继承RouteAware并实现onNavigationEnd()方法。

它是一个名为@bespunky/angular-zen的库的一部分。

NPM install @bespunky/angular-zen 让你的AppComponent扩展RouteAware并添加一个onNavigationEnd()方法。

import { Component     } from '@angular/core';
import { NavigationEnd } from '@angular/router';
import { RouteAware    } from '@bespunky/angular-zen/router-x';

@Component({
    selector   : 'app-root',
    templateUrl: './app.component.html',
    styleUrls  : ['./app.component.css']
})
export class AppComponent extends RouteAware
{    
    protected onNavigationEnd(event: NavigationEnd): void
    {
        // Handle authentication...
    }
}

RouteAware还有其他好处，比如: ✨任何路由器事件都可以有处理程序方法(Angular支持的路由器事件)。 ✨使用这个。路由器访问路由器 ✨使用这个。访问激活路由的路由 ✨使用this.componentBus访问RouterOutletComponentBus服务

简单的答案 角8。*

constructor(private route:ActivatedRoute) {
  console.log(route);
}

我会这样写:

ngOnInit() {
this.routed = this.router.events.map( event => event instanceof NavigationStart )
  .subscribe(() => {
  } );
}

ngOnDestroy() {
this.routed.unsubscribe();
}

对于Angular 7，应该这样写:

this.router.events。订阅((事件:事件)=> {})

具体示例如下:

import { Component } from '@angular/core'; 
import { Router, Event, NavigationStart, NavigationEnd, NavigationError } from '@angular/router';

@Component({
    selector: 'app-root',
    template: `<router-outlet></router-outlet>`
})
export class AppComponent {

    constructor(private router: Router) {

        this.router.events.subscribe((event: Event) => {
            if (event instanceof NavigationStart) {
                // Show loading indicator
            }

            if (event instanceof NavigationEnd) {
                // Hide loading indicator
            }

            if (event instanceof NavigationError) {
                // Hide loading indicator

                // Present error to user
                console.log(event.error);
            }
        });

   }
}
