Angular:如果重定向到另一个页面，我想让进度条保持活动状态

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

const routes: Routes = [
  { path: '', redirectTo: '/new-page', pathMatch: 'full' },
  { path: 'new-page', component: NewPageComponent },
  // 其他页面配置
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

import { Injectable } from '@angular/core';
import { HttpRequest, HttpHandler, HttpEvent, HttpInterceptor } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable()
export class ProgressBarInterceptor implements HttpInterceptor {
  constructor(private progressBarService: ProgressBarService) {}

  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    this.progressBarService.show(); // 显示进度条

    return next.handle(request).pipe(
      finalize(() => {
        this.progressBarService.hide(); // 隐藏进度条
      })
    );
  }
}

import { HttpClientModule, HTTP_INTERCEPTORS } from '@angular/common/http';
import { ProgressBarInterceptor } from './progress-bar.interceptor';

@NgModule({
  imports: [HttpClientModule],
  providers: [
    {
      provide: HTTP_INTERCEPTORS,
      useClass: ProgressBarInterceptor,
      multi: true
    }
  ]
})
export class AppModule { }

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

@Component({
  selector: 'app-example',
  template: `
    <button (click)="redirectToNewPage()">重定向到新页面</button>
  `
})
export class ExampleComponent {
  constructor(private router: Router) {}

  redirectToNewPage() {
    this.router.navigate(['/new-page']);
  }
}
