用Angular获取当前地址的路径path（也就是网址/#后面那坨url）

import { Location } from '@angular/common';
import { Component } from '@angular/core';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss'],
})
export class AppComponent {
  constructor(private location: Location) { }
  ngOnInit() {
    //如果访问路径是http://localhost:4200/#/home，输出结果是  /home
    console.log(this.location.path());
  }
}
