Angular 路由器 url 返回斜杠

Question

我试图通过使用 Router 获取当前路由器路径，但是当我执行 console.log(this.router.url) 时它返回“/”，尽管我在“/登录”。但是当我安慰整个 this.router 对象时，有一个属性 url 具有值“/login”。

这是我来自 app.component.ts 的代码

export class AppComponent implements OnInit{
  constructor(private router: Router) {}

  ngOnInit(){
    console.log(this.router);
  }

}

app.module.routing.ts

import {NgModule} from '@angular/core';
import {PreloadAllModules, RouterModule, Routes} from '@angular/router';

import {NotFoundComponent} from './not-found/not-found.component';
import {AuthGuard} from './auth/auth-guard.service';

const appRoutes: Routes = [
  { path: '', loadChildren: './first/first.module#FirstModule'},
  { path: 'login', loadChildren: './login/login.module#LoginModule'},
  { path: '404', component: NotFoundComponent, canActivate: [AuthGuard] },
  { path: '**', redirectTo: '/404'}
];

@NgModule({
  imports: [RouterModule.forRoot(appRoutes, {preloadingStrategy: PreloadAllModules})],
  exports: [RouterModule]
})
export class AppModuleRouting {}

和 FirstModule 路由:

import {NgModule} from '@angular/core';
import {RouterModule, Routes} from '@angular/router';

import {FirstComponent} from './first.component';
import {AuthGuard} from '../auth/auth-guard.service';

const firstRoutes: Routes = [
  { path: '', component: FirstComponent, canActivate: [AuthGuard], children:[
    { path: '', loadChildren: './content-container/container.module#ContainerModule' }
  ]}
];
@NgModule({
  imports: [RouterModule.forChild(firstRoutes)],
  exports: [RouterModule]
})
export class FirstRoutes {}

您可以使用Location 服务(https://angular.io/api/common/Location ) 及其方法 path，它将为您提供没有基本 href 的 url。相反，window.location.pathname 不知道您的 Angular 玩具，并且会为您提供包含基本 href 的路径。

import { Location } from '@angular/common';

export class AppComponent implements OnInit {
  constructor(private location: Location) {}

  ngOnInit(){
    console.log(this.location.path());
  }

}
