UrlTree

Represents the parsed URL.

interface UrlTree { root: UrlSegmentGroup queryParams: Params fragment: string | null get queryParamMap: ParamMap toString(): string }

说明

Since a router state is a tree, and the URL is nothing but a serialized state, the URL is a serialized tree. UrlTree is a data structure that provides a lot of affordances in dealing with URLs

Example

@Component({templateUrl:'template.html'}) class MyComponent { constructor(router: Router) { const tree: UrlTree = router.parseUrl('/team/33/(user/victor//support:help)?debug=true#fragment'); const f = tree.fragment; // return 'fragment' const q = tree.queryParams; // returns {debug: 'true'} const g: UrlSegmentGroup = tree.root.children[PRIMARY_OUTLET]; const s: UrlSegment[] = g.segments; // returns 2 segments 'team' and '33' g.children[PRIMARY_OUTLET].segments; // returns 2 segments 'user' and 'victor' g.children['support'].segments; // return 1 segment 'help' } }
