如何使用TypeScript在Angular 2中的浏览器中获取当前URL？

Question

I need to get the current URL present in the browser in my Angular 2 application.

In JavaScript normally we do it using the window object.

How can I do this in Angular 2 using TypeScript?

Thanks.

Answer 1

This is late but I thought it was worth updating. As of Angular2 final release you can import DOCUMENT from @angular/common and use that to get to the location.

import { Component, Inject } from '@angular/core';
import { DOCUMENT } from '@angular/common';

...

export class YourComponent {

    constructor(@Inject(DOCUMENT) private document: Document) { 
        console.log(this.document.location.href);
    }
}

Answer 2

It is not necessary to import complicated packages or inject something. Just use the methods you can find on window.location !

Such as:

• window.location.href gives you the full URL
• window.location.hostname gives you the host name
• window.location.origin with this command you get the host name with protocol (eg https://)
• and more as you can see here: click me

For IE<=10 users: location.origin may not be available, then you have to use location.protocol + "//" + location.hostname or use a polyfill or package like location-origin

Answer 3

You can

• inject Location and get the URL by location.path() (see also Location and HashLocationStrategy stopped working in beta.16 )
• get it from the browser directly using window.location.pathname

Answer 4

Import the ActivatedRoute, (and the rest of the Router stuff too, if you want)

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

making sure it's injected into the constructor,

constructor(private route: ActivatedRoute) { ... }

and on ngOnInit you can use this.route to inspect the URL. For instance, all the segments are in an array, which you can string together, as @ibgib suggested, like this:

let path = this.route.snapshot.url.join('/');

to give you something like "mars/moons/phobos".

For future travelers, a lot of the other answers are great. Another option, if you want everything before the pathname (eg https://example.com ) then you can use:

window.location.origin

Here's a W3 article on the different window.location properties you can use: http://www.w3schools.com/js/js_window_location.asp

This Link helped me:

  public static getCurrentAbsoluteSiteUrl(): string {
    if (window
        && "location" in window
        && "protocol" in window.location
        && "pathname" in window.location
        && "host" in window.location) {
      return window.location.protocol + "//" + window.location.host + window.location.pathname;
    }
    return null;
}
