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。

欲了解更多信息，请查看本文http://blog.2muchcoffee.com/getting-current-state-in-angular2-router/ 或者从NPM安装ng2-router-helper

npm install ng2-router-helper

给那些还在寻找这个的人。在Angular 2上。有几种方法。

constructor(private router: Router, private activatedRoute: ActivatedRoute){

   // string path from root to current route. i.e /Root/CurrentRoute
   router.url 

    // just the fragment of the current route. i.e. CurrentRoute
   activatedRoute.url.value[0].path

    // same as above with urlSegment[]
   activatedRoute.url.subscribe((url: urlSegment[])=> console.log(url[0].path))

   // same as above
   activatedRoute.snapshot.url[0].path

   // the url fragment from the parent route i.e. Root
   // since the parent is an ActivatedRoute object, you can get the same using 
   activatedRoute.parent.url.value[0].path
}

如果你导入了路由器，那么你可以简单地使用一些东西

This.router.url === "/search"

否则执行以下操作

1)导入路由器

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

2)在构造函数中声明它的条目

constructor(private router: Router) { }

3)在你的工作中发挥它的价值

yourFunction(){
    if(this.router.url === "/search"){
        //some logic
    }
}

@victor的回答帮助了我，这是和他一样的答案，但有一点细节，因为它可能会帮助到别人

在组件文件中:

import {ActivatedRouteSnapshot} from '@angular/router';

constructor(state: ActivatedRouteSnapshot) {
    console.log(state.path)
}

在路由文件中:

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

可以在.ts文件中使用

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

constructor(private router: Router) {}

this.router.events.subscribe(value => {
      if (value instanceof NavigationStart) {
        console.log(value) // your current route
      }
    });
