导航到子组件时未调用ngOnInit（但是按预期方式调用了构造函数和ngOnDestroy）

Question

我有一个组件ViewBotsComponent，它有2个子组件：ViewCodeBasedBotComponent和ViewPipelineBasedBotsComponent。

我将其路由如下：

const routes: Route[] = [
  {
    path: "core", component: CoreWrapperComponent, children:[
      {path: 'viewbots', component: ViewBotsComponent, children:
          [
            {path: 'codebased', component: ViewCodeBasedBotComponent},
            {path: 'intelligent', component: ViewPipelineBasedBotsComponent},
            // {path: '', component: ViewCodeBasedBotComponent}
          ]
      }
  },
  ...
]

当我在http://localhost:4200/core/viewbots/codebased和http://localhost:4200/core/viewbots/intelligent之间切换时，正按预期为子组件调用constructor和ngOnDestroy，但没有ngOnit被称为。

现在变得很奇怪：如果重新加载浏览器标签，一切正常，
预期会调用ngOnInit。

以下是30秒的问题视频，请注意，最初未记录ngOninit，但重新加载后正在记录它： https://youtu.be/_HCh3eJAX9I

以下是我的代码：

父组件html：（view-bots.component.html）

<ul class="nav nav-tabs my-2">
  <li class="nav-item">
    <a class="nav-link" [ngClass]="{'tab-active':activeTab==='codebased'}" (click)="changeActiveTab('codebased')" ><strong>CODE BASED BOTS</strong></a>
  </li>
  <li class="nav-item">
    <a class="nav-link" [ngClass]="{'tab-active':activeTab==='intelligent'}" (click)="changeActiveTab('intelligent')" ><strong>PIPELINE BASED BOTS</strong></a>
  </li>
</ul>

<router-outlet></router-outlet>

父组件ts：（view-bots.component.ts）

export class ViewBotsComponent implements OnInit {

  botList$: Observable<IBot[]>;
  activeTab:string = "codebased";

  constructor(
    private serverService: ServerService,
    private constantsService: ConstantsService,
    private router:Router,
    private store: Store) {
  }

  ngOnInit() {
    console.log('ViewBotsComponent init');
  }
  changeActiveTab(activeTab){
    console.log("hi");
    this.router.navigate(['core','viewbots',activeTab]);
    this.activeTab =activeTab

  }
}

Child1 html：view-pipeline-based-bots.component.html

<p>pipelineBasedBotList</p>

Child1 ts：view-pipeline-based-bots.component.ts

export class ViewPipelineBasedBotsComponent implements OnInit, OnDestroy {
  ngOnDestroy(): void {
    console.log('pipelineBasedBotList destroyed');
  }

  constructor() {
    console.log("ViewPipelineBasedBotsComponent constructor")
  }

  ngOnInit() {
    console.log('pipelineBasedBotList init');
  }

}

Child2 html：基于视图代码的bot.component.html

<p>ViewCodeBasedBotComponent</p>

Child2 ts：基于视图代码的bot.component.ts

export class ViewCodeBasedBotComponent implements OnInit, OnDestroy {

  constructor(private store: Store) {
    console.log("ViewCodeBasedBotComponent constructor")
  }

  ngOnInit(){
    console.log("ViewCodeBasedBotComponent init")
  }

  ngOnDestroy(): void {
    console.log("ViewCodeBasedBotComponent destroyed")
  }

}
