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
}
}
]
}
];
以及以下解析器:
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();
}
}
在应用程序引导后,NestedResolver和AppResolver将首先执行并同时发出请求。
我们可以更改代码并实现NestedResolver等待AppResolver解析并有权访问AppResolver解析数据吗?

我知道这个问题很老,但万一有人偶然发现它(像我一样)。
这是一个已知的错误,并且已经修复。只需将您的路由器版本更新为高于或等于2.1.0的版本,您应该好好去。这里的参考是相关的issue on github和associated fix
