我该怎么获取当前地址栏的URL，使用angular 2?

Question

angular 2 怎么获取当前地址栏的URL

Answer 1

在Angular8中使用PlatformLocation类，此类保存url链接信息，如基地址，端口号等。使用如下：constructor(private platformLocation: PlatformLocation) {}ngOnInit() {console.log(this.platformLocation.href);//href属性即是当前url}

Answer 2

import { Component, OnInit, Inject } from '@angular/core';import {ActivatedRoute, Params} from '@angular/router';@Component({selector: 'demo',template: `<div></div>`})export class DemoComponent implements OnInit {constructor(@Inject(ActivatedRoute) private router: ActivatedRoute) { }ngOnInit() {this.router.params.subscribe((params: Params) => {// params});}}

Answer 3

rootScope.$on('$stateChangeSuccess', function (ev, to, toParams, from, fromParams) {$rootScope.previousState = from;$rootScope.previousParams = fromParams;});

Answer 4

import { Component, OnInit, Inject } from '@angular/core';import {ActivatedRoute, Params} from '@angular/router';@Component({selector: 'demo',template: `<div></div>`})export class DemoComponent implements OnInit {constructor(@Inject(ActivatedRoute) private router: ActivatedRoute) { }ngOnInit() {this.router.params.subscribe((params: Params) => {// params});}
