Angular 10:当使用浏览器的后退按钮从外部URL返回时，ngOnInit在火狐中部署的应用程序版本中不会触发。

import { Injectable } from '@angular/core';
import { CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot, UrlTree } from '@angular/router';
import { Observable } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class OnInitGuard implements CanActivate {
  canActivate(
    next: ActivatedRouteSnapshot,
    state: RouterStateSnapshot): Observable<boolean | UrlTree> | Promise<boolean | UrlTree> | boolean | UrlTree {
    // 在这里执行一些代码，确保ngOnInit被正确触发
    return true;
  }
}

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { AppComponent } from './app.component';
import { OnInitGuard } from './on-init.guard';

const routes: Routes = [
  {
    path: '',
    component: AppComponent,
    canActivate: [OnInitGuard] // 使用OnInitGuard守卫
  }
];

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