在花了一些时间寻找解决方案后，我找到了Angular 13.1.1的两个更新的变通方案:

第一选择:

  constructor(private router: Router) {
    router.events.forEach((event) => {
      if (event instanceof NavigationStart) {
        // Your code
        // Use (event.url) to get URL that is being navigated
      }
    });
  }

第二个选项

routerSubscription:订阅| undefined; 构造函数(私有路由器:router) {} ngAfterViewInit(): void { 这一点。routerSubscription = this.router.events.subscribe((event) => { if(事件实例of NavigationEnd) { //你的代码 //使用(event.url)获取正在导航的URL ｝ })； ｝

记得取消订阅销毁循环

 ngOnDestroy(): void {
    this.routerSubscription?.unsubscribe();
  }

还要根据您的情况注意是否更好地使用

事件实例的NavigationStart

or

事件实例的NavigationEnd

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);
  });
}

RxJS 6

router.events.pipe(filter(event => event instanceof NavigationStart))

感谢Peilonrayz(见下面的评论)

new router >= RC.3

import { Router, NavigationStart, NavigationEnd, NavigationError, NavigationCancel, RoutesRecognized } from '@angular/router';

constructor(router:Router) {
  router.events.forEach((event) => {
    if(event instanceof NavigationStart) {
    }
    // NavigationEnd
    // NavigationCancel
    // NavigationError
    // RoutesRecognized
  });
}

你也可以通过给定的事件进行过滤:

import 'rxjs/add/operator/filter';

constructor(router:Router) {
  router.events
    .filter(event => event instanceof NavigationStart)
    .subscribe((event:NavigationStart) => {
      // You only receive NavigationStart events
    });
}

使用成对操作符来获取先前和当前事件也是一个不错的想法。https://github.com/angular/angular/issues/11268#issuecomment-244601977

进口的rxjs /添加/运营商/成对的; import {Router} from '@angular/ Router '; 导出类AppComponent { 构造函数(私有路由器:router) { This.router.events.pairwise ().subscribe((event) => { console.log(事件); })； }; ｝

在组件中，你可能想尝试这样做:

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

constructor(private router: Router) {
router.events.subscribe(
        (event) => {
            if (event instanceof NavigationStart)
                // start loading pages
            if (event instanceof NavigationEnd) {
                // end of loading paegs
            }
        });
}

可以使用以下方法检测路由变化:

import {Router, ActivatedRoute} from '@angular/ Router '; 构造函数(私有路由:ActivatedRoute) {} This.router.events.subscribe ((event) => { 如果(事件){ / /做某事 ｝ })；

我会这样写:

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

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