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*/
}
)

@Ludohen的回答很好，但如果你不想使用instanceof，请使用下面的方法

this.router.events.subscribe(event => {
  if(event.constructor.name === "NavigationStart") {
    // do something...
  }
});

通过这种方式，您可以检查当前事件名称作为字符串，如果事件发生，您可以执行您计划的函数要执行的操作。

Angular 7，如果你想订阅路由器

import { Router, NavigationEnd } from '@angular/router';

import { filter } from 'rxjs/operators';

constructor(
  private router: Router
) {
  router.events.pipe(
    filter(event => event instanceof NavigationEnd)  
  ).subscribe((event: NavigationEnd) => {
    console.log(event.url);
  });
}

在Angular 8中，你应该这样做。router.events。订阅((事件:事件)=> {})

例子:

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

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

    constructor(private router: Router) {
        //Router subscriber
        this.router.events.subscribe((event: Event) => {
            if (event instanceof NavigationStart) {
                //do something on start activity
            }

            if (event instanceof NavigationError) {
                // Handle error
                console.error(event.error);
            }

            if (event instanceof NavigationEnd) {
                //do something on end activity
            }
        });
   }
}

我会这样写:

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

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

角4。X及以上:

这可以通过使用ActivatedRoute类的url属性来实现，如下所示:

this.activatedRoute.url.subscribe(url =>{
     console.log(url);
});

注意: 你需要从angular/router包中导入和注入提供商

import { ActivatedRoute } from '@angular/router`

and

constructor(private activatedRoute : ActivatedRoute){  }
