javascript - 无法从 Angular 路由器获取路径或网址

Question

我无法从 ActivatedRoute 或路由器导入中获取 URL 或路径。它为路径“”输出空白，为 URL 输出“/”。我记得使用的是工作版本。唯一捕获正确路由的是 Router.events。我也无法订阅 ActivatedRoute 中的 URL。这是代码

import { Component, OnInit, ViewChild, ElementRef } from '@angular/core';
import { Router, ActivatedRoute, UrlSegment, NavigationStart, RoutesRecognized } from '@angular/router';

@Component({
  selector: 'api-dashboard',
  templateUrl: './dashboard.component.html',
  styleUrls: ['./dashboard.component.css']
})
export class DashboardComponent implements OnInit {

  routePath: string = '';

  constructor(
    private _r: Router,
    private _ar: ActivatedRoute) {
    this._r.events.subscribe((event: any) => {
      if (event instanceof RoutesRecognized) {
          // '/teams' output with route http://localhost:4200/teams
        console.log(event.url);
      }
      // NavigationStart // NavigationEnd // NavigationCancel // NavigationError // RoutesRecognized
    });

  }


  ngOnInit() {
    console.log(this._ar.pathFromRoot.toString()); // Blank output with route http://localhost:4200/teams
    console.log(this._ar.routeConfig.path.toString());  // Blank output with route http://localhost:4200/teams
    console.log(this._ar.snapshot.url);  // Blank output with route http://localhost:4200/teams
    this._ar.url.subscribe((urlsegment: UrlSegment[]) =>{
      console.log(urlsegment) // Unable to subscribe with route change to /teams
    })
  }

}

我在这里遗漏了什么吗？我看过这个Angular router url returns slash

我的路线:

const APPMainRoutes: Routes = [
    {path: '', redirectTo: '/login', pathMatch: 'full'},
    {path: 'teams', component: CollaborateComponent},
    {path: 'login', component: LoginComponent},
];

你可以这样获取 url 信息:

ngOnInit() {
    console.log(this._r.url);
  }

如果需要获取url中的queryParams 你可以获得:

this._r.snapshot.queryParamMap
