目前的文档只讨论了获取路由参数,而不是实际的路由段。

例如,如果我想找到当前路由的父,这是怎么可能的?


当前回答

this.router.events.subscribe((val) => {
   const currentPage = this.router.url; // Current page route
  const currentLocation = (this.platformLocation as any).location.href; // Current page url
});

给那些还在寻找这个的人。在Angular 2上。有几种方法。

constructor(private router: Router, private activatedRoute: ActivatedRoute){

   // string path from root to current route. i.e /Root/CurrentRoute
   router.url 

    // just the fragment of the current route. i.e. CurrentRoute
   activatedRoute.url.value[0].path

    // same as above with urlSegment[]
   activatedRoute.url.subscribe((url: urlSegment[])=> console.log(url[0].path))

   // same as above
   activatedRoute.snapshot.url[0].path

   // the url fragment from the parent route i.e. Root
   // since the parent is an ActivatedRoute object, you can get the same using 
   activatedRoute.parent.url.value[0].path
}

获取路由段:

import { ActivatedRoute, UrlSegment } from '@angular/router';

constructor( route: ActivatedRoute) {}

getRoutes() { const segments: UrlSegment[] = this.route.snapshot.url; }

要找到当前路由的父路由,你可以使用相对路由从路由器获取UrlTree:

var tree:UrlTree = router.createUrlTree(['../'], {relativeTo: route});

然后得到主出口的分段:

tree.root.children[PRIMARY_OUTLET].segments;

这可能是你的答案,使用激活路由的params方法从你想要读取的URL/路由获取参数,下面是演示片段

import {ActivatedRoute} from '@angular/router'; 
@Component({
})
export class Test{
constructor(private route: ActivatedRoute){
this.route.params.subscribe(params => {
             this.yourVariable = params['required_param_name'];
        });
    }
}

在Angular2 Rc1中,你可以注入一个routessegment,然后将它传递给.navigate()方法:

constructor(private router:Router,private segment:RouteSegment) {}

ngOnInit() {
  this.router.navigate(["explore"],this.segment)
}
