ActivatedRoute

interface

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。

Provides access to information about a route associated with a component that is loaded in an outlet. Use to traverse the RouterState tree and extract information from nodes.

`queryParams: Observable<Params>`	一个 `Observable`，表示所有路由共享的查询参数（`?`）。 An observable of the query parameters shared by all the routes.
`fragment: Observable<string>`	一个 `Observable`，表示由所有路由共享的 URL 片段（`#`）。 An observable of the URL fragment shared by all the routes.
`data: Observable<Data>`	一个 `Observable`，表示该路由的静态数据和解析出的数据。 An observable of the static and resolved data of this route.
`outlet: string`	本路由对应的出口名，是个常量 The outlet name of the route. It's a constant
`component: Type<any> \| string \| null`	本路由对应的组件，是个常量 The component of the route. It's a constant
`routeConfig: Route \| null`	只读用于匹配本路由的配置项。 The configuration used to match this route.
`root: ActivatedRoute`	只读路由器状态树的根节点。 The root of the router state.
`parent: ActivatedRoute \| null`	只读在路由器状态树中，当前路由的父路由。 The parent of this route in the router state tree.
`firstChild: ActivatedRoute \| null`	只读在路由器状态树中，当前路由的第一个子路由。 The first child of this route in the router state tree.
`children: ActivatedRoute[]`	只读在路由器状态树中，当前路由的所有子路由。 The children of this route in the router state tree.
`pathFromRoot: ActivatedRoute[]`	只读在路由器状态树中从根节点开始到当前路由的完整路径。 The path from the root of the router state tree to this route.
`paramMap: Observable<ParamMap>`	只读 An Observable that contains a map of the required and optional parameters specific to the route. The map supports retrieving single and multiple values from the same parameter.
