你可以试试

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

constructor(private router: Router, private activatedRoute:ActivatedRoute) {
console.log(activatedRoute.snapshot.url)  // array of states
console.log(activatedRoute.snapshot.url[0].path) }

替代的方法

router.location.path();   this works only in browser console. 

window。location。pathname给出了路径名。

获取路由段:

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

constructor( route: ActivatedRoute) {}

getRoutes() { const segments: UrlSegment[] = this.route.snapshot.url; }

角RC4:

你可以从@angular/ Router中导入Router

然后注入:

constructor(private router: Router ) {

}

然后调用它的URL参数:

console.log(this.router.url); //  /routename

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;

本机窗口对象也可以正常工作

console.log('URL:' + window.location.href);
console.log('Path:' + window.location.pathname);
console.log('Host:' + window.location.host);
console.log('Hostname:' + window.location.hostname);
console.log('Origin:' + window.location.origin);
console.log('Port:' + window.location.port);
console.log('Search String:' + window.location.search);

注意:不要在服务器端渲染中使用这个

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。
