Angular 2 rc2

router.urlTree.contains(router.createUrlTree(['/home']))

你可以使用this.activatedRoute.pathFromRoot。

import {ActivatedRoute} from "@angular/router";
constructor(public activatedRoute: ActivatedRoute){

}

在pathFromRoot的帮助下，您可以获得父URL的列表，并检查URL中所需的部分是否与您的条件匹配。

Angular 2 rc2

router.urlTree.contains(router.createUrlTree(['/home']))

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
            }); 

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;

import { Router } from '@angular/router';
constructor(router: Router) { 
      console.log(router.routerState.snapshot.url);
}
