如何获取Angular 5中当前请求的url (window.location)？

import { Location } from '@angular/common';

constructor(private location: Location) { }

const currentUrl = this.location.path();

import { Component } from '@angular/core';
import { Location } from '@angular/common';

@Component({
  selector: 'app-your-component',
  template: `
    <p>Current URL: {{ currentUrl }}</p>
  `
})
export class YourComponent {
  currentUrl: string;

  constructor(private location: Location) {
    this.currentUrl = this.location.path();
  }
}
