您可以使用ActivatedRoute来获取当前路由器

原文答案(RC版)

我在AngularJS谷歌Group上找到了一个解决方案，非常简单!

ngOnInit() {
  this.router.subscribe((url) => console.log(url));
}

这是最初的答案

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;

Angular 2 rc2

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

当我想要根据路线改变背景时，我面临着这个问题。但它只在我浏览网站时工作，而不是当我刷新页面时。

在router.events.subscribe()中，这是事件。导航时的Url，刷新时的this。router。Url。

现在它起作用了:

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

constructor(private router: Router) {}

public ngOnInit() {
    this.router.events.subscribe((events:any) => {
        let theme = '';
        if (events instanceof NavigationStart) { theme = events.url; }
        else { theme = this.router.url; }
        
        if(theme === '/videos') { ... }
}

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

为了可靠地获得完整的当前路由，您可以使用这个

this.router.events.subscribe(
  (event: any) => {
    if (event instanceof NavigationEnd) {
      console.log('this.router.url', this.router.url);
    }
  }
);
