Angular 2嵌套路由解析执行

Question

例如,如果我有以下路线组织:

const appRoutes: Routes = [
    {
        path: "",
        component: AppComponent,
        resolve: {
            app: AppResolver
        },
        children: [
            {
                path: "",
                component: NestedComponent,
                resolve: {
                    subscribers: NestedResolver
                }
            }
        ]
    }
];

和以下解析器:

export class AppResolver implements Resolve<any> {
    constructor(private appService: AppService) {}
    resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<any> {
        return this.appService.getAppData();
    }
}

export class NestedResolver implements Resolve<any> {
    constructor(private nestedService: NestedService) {}
    resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<any> {
        console.log(route.parent.data); //when this is executed route.parent.data is empty :(
        return this.nestedService.getNestedData();
    }
}

应用程序引导后,NestedResolver和AppResolver将首先执行并并行发出请求.

我们可以更改代码并实现NestedResolver等待AppResolver解析并可以访问AppResolver解析数据吗？

我知道这个问题已经很老了，但以防万一有人偶然发现它（像我一样）。

这是一个已知的错误，现已修复。只需将您的路由器版本更新到更高或等于 2.1.0 即可。供参考的是github 上的相关问题和相关修复
