ActivatedRoute
包含与当前组件相关的路由信息。ActivatedRoute
也可用于遍历路由器的状态树。
Contains the information about a route associated with a component loaded in an outlet. An ActivatedRoute
can also be used to traverse the router state tree.
- interface ActivatedRoute {
- snapshot: ActivatedRouteSnapshot
- url: Observable<UrlSegment[]>
- params: Observable<Params>
- queryParams: Observable<Params>
- fragment: Observable<string>
- data: Observable<Data>
- outlet: string
- component: Type<any> | string | null
- routeConfig: Route | null
- root: ActivatedRoute
- parent: ActivatedRoute | null
- firstChild: ActivatedRoute | null
- children: ActivatedRoute[]
- pathFromRoot: ActivatedRoute[]
- paramMap: Observable<ParamMap>
- queryParamMap: Observable<ParamMap>
- toString(): string
- }
说明
@Component({...})
class MyComponent {
constructor(route: ActivatedRoute) {
const id: Observable<string> = route.params.map(p => p.id);
const url: Observable<string> = route.url.map(segments => segments.join(''));
// route.data includes both `data` and `resolve`
const user = route.data.map(d => d.user);
}
}
