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?

方法1:使用Angular: this.router.url
import { Component } from '@angular/core';
// Step 1: import the router
import { Router } from '@angular/router';
@Component({
template: 'The href is: {{href}}'
/*
Other component settings
*/
})
export class Component {
public href: string = "";
//Step 2: Declare the same in the constructure.
constructor(private router: Router) {}
ngOnInit() {
this.href = this.router.url;
// Do comparision here.....
///////////////////////////
console.log(this.router.url);
}
}
方法二:窗口。如果你不想使用路由器,就像我们在Javascript中做的那样
this.href= window.location.href;

这很简单,在angular 2中,你只需要像这样导入Router库:
import { Router } from '@angular/router';
然后在组件或服务的构造函数中,你必须像这样实例化它:
constructor(private _router: Router) {}
然后在代码的任何部分,函数、方法、构造等等:
this._router.events
.subscribe(
(url:any) => {
let _ruta = "";
url.url.split("/").forEach(element => {
if(element!=="" && _ruta==="")
_ruta="/"+element;
});
console.log("route: "+_ruta); //<<<---- Root path
console.log("to URL:"+url.url); //<<<---- Destination URL
console.log("from URL:"+this._router.url);//<<<---- Current 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
}

将Location注入组件并读取Location .path(); 你需要在某个地方添加ROUTER_DIRECTIVES,这样Angular才能解析Location。你需要在这个模块中添加import: [RouterModule]。
更新
在V3 (RC.3)路由器中,您可以注入ActivatedRoute,并使用它的snapshot属性访问更多细节。
constructor(private route:ActivatedRoute) {
console.log(route);
}
or
constructor(private router:Router) {
router.events.subscribe(...);
}
另见Angular 2的路由器事件侦听器
router.events。订阅(e => { if (e instanceof NavigationEnd) { 这一点。currentUrl = e.url; } });
this.router.events.subscribe((val) => {
const currentPage = this.router.url; // Current page route
const currentLocation = (this.platformLocation as any).location.href; // Current page url
});
