angular 路由器解析器 - 重新加载时从父级获取参数

Question

我有一个这样的路由，有一个子路由的解析器。

 {
        path: 'organizations/:oid',
        component: AdminOrganizationComponent,
        children: [
          {
            path: 'profile',
            component: AdminOrganizationProfileComponent,
            resolve: { organization: OrganizationResolver }
          },
          { path: '', redirectTo: 'profile', pathMatch: 'full' }
        ]
      },

解析器看起来像这样

@Injectable()
export class OrganizationResolver implements Resolve<Observable<Organization>> {
  private activeOrganization: Organization;
  constructor(private route:ActivatedRoute) {}

  setUser(organization: Organization) {
    this.activeOrganization = organization;
  }

  resolve() {
    return of(this.activeOrganization);
  }
}

在导航到路线之前，我使用该服务来设置所选组织。

  edit(organization) {
    this.organizationResolver.setUser(organization);
    this.router.navigate(['/admin/organizations', organization.id]);
  }

目前一切正常，我可以使用 snapshot.data 获取所选组织。

现在当我重新加载路线时

/organizations/12345/profile

我希望解析器检查是否存储了 activeOrganization。如果不是，它应该通过 http.get 和 12345 作为 id.

检索它

我的问题是我不知道使用哪个工具可以检索参数。通常在组件中我可以简单地使用 activatedRoute.parent.params 但在这种情况下，注入的 activatedRoute.parent 是 null.

我想既然我已经在 root 中提供了解析器，parent=null 是有意义的，但是注销快照我在父级中得到 null 以及 firstChild ...

ActivatedRouteSnapshot Contains the information about a route associated with a component loaded in an outlet at a particular moment in time. ActivatedRouteSnapshot can also be used to traverse the router state tree.

import { Resolve, ActivatedRouteSnapshot } from '@angular/router';

  resolve(route: ActivatedRouteSnapshot) {
    let id: any = route.params['id'];
  }
