在我的 Angular 10 应用程序中,我有一个带有多个子路由的路由,上面有一个 canActivate 保护。

{
    path: 'settings', component: SettingsComponent,
    children: [
      { path: '', redirectTo: 'index-types', pathMatch: 'full' },
      {
        path: 'index-types', component: IndexTypesComponent,
        resolve: [IndexTypeResolverService],
        canActivateChild: [ErrorPageGuard],
        children: [
          { path: '', component: IndexTypeStartComponent },
          { path: 'new', component: IndexTypeEditComponent },
          {
            path: ':id',
            component: IndexTypeDetailComponent,
            resolve: [IndexTypeResolverService]
          },
          {
            path: ':id/edit',
            component: IndexTypeEditComponent,
            resolve: [IndexTypeResolverService]
          }
        ]
      },
      { path: 'users', component: UsersComponent }
    ]
  }

我正在尝试获取 canActivtate 保护,以防止用户输入带有 :id 和 :id/edit 路由中不存在的 ID 的 URL。canActivate 似乎在防止用户在 URL 中输入不存在的 id 方面做得很好,但问题是当用户手动输入正确的 id 时,它的行为就像它不正确一样 - 但是当单击具有相同正确ID的routerLink它可以工作。

我试图调试它,并得出结论,在下面的代码中,this.indexTypeService应该有一个我的 indexTypes 列表实际上在该列表中没有任何内容,只有在用户手动输入任何内容的情况下地址栏:

export class ErrorPageGuard implements CanActivate, CanActivateChild {

  constructor(private indexTypeService: IndexTypeService, private router: Router) { }

  canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<boolean> | Promise<boolean> | boolean {
    //TODO: works when navigating programmatically, but not when navigating manually

    let state_id = state.url.split('/')[state.url.split('/').length - 1];
    let route_id = +route.params.id;
    let id = Object.keys(route.params).length > 0 ? route_id : (!isNaN(+state_id) ? +state_id : -1);


    if ((Object.keys(route.params).length === 0)
      || (this.indexTypeService.getIndexType(id) !== undefined)) {
      return true;
    }
    else {
      this.router.navigate(['/']);
      return false;
    }
  }

  canActivateChild(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<boolean> | Promise<boolean> | boolean {
    return this.canActivate(route, state);
  }
}

我究竟做错了什么?
