ActivatedRouteSnapshot
包含与当前组件相关的路由的当前瞬间信息。ActivatedRoute 也可用于遍历路由器的状态树。 ActivatedRouteSnapshot 也能用于遍历路由器状态树。
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.
interface ActivatedRouteSnapshot {
routeConfig: Route | null
url: UrlSegment[]
params: Params
queryParams: Params
fragment: string
data: Data
outlet: string
component: Type<any> | string | null
root: ActivatedRouteSnapshot
parent: ActivatedRouteSnapshot | null
firstChild: ActivatedRouteSnapshot | null
children: ActivatedRouteSnapshot[]
pathFromRoot: ActivatedRouteSnapshot[]
paramMap: ParamMap
queryParamMap: ParamMap
toString(): string
}
说明
@Component({templateUrl:'./my-component.html'})
class MyComponent {
constructor(route: ActivatedRoute) {
const id: string = route.snapshot.params.id;
const url: string = route.snapshot.url.join('');
const user = route.snapshot.data.user;
}
}
