How to get access token from the url [duplicate]

Question

I'm getting this URL after I'm authenticated to Google

http://localhost:3000/_oauth/google#access_token=ya29.5HxuYol1Io8JLeGePDznbfkkwu_PC4uodKwG8_1clFYAn9AgdOV1WGpOTNQP3s76HAsn7Y4zWw&token_type=Bearer&expires_in=3600

How to get access_token value from this url?

I tried solutions in following urls, none of them are working

Using the GET parameter of a URL in JavaScript

Answer 1

Using modern ways, there are better, more reliable ways to get access token field:

var urlString = 'http://localhost:3000/_oauth/google#access_token=ya29.5HxuYol1Io8JLeGePDznbfkkwu_PC4uodKwG8_1clFYAn9AgdOV1WGpOTNQP3s76HAsn7Y4zWw&token_type=Bearer&expires_in=3600';

var url = new URL(urlString);
// OR: If you want to use the current page's URL
var url = window.location;

var access_token = new URLSearchParams(url.search).get('access_token');

You can also see how this approach makes it easy to get the other parameters in addition. This URLSearchParams approach is supported by all browsers except old instances of IE.

If the above doesn't work (didn't for me) just add 'hash' to window.location, this is also single line code

var access_token = new URLSearchParams(window.location.hash).get('access_token');

I like RegEx so here's a RegEx answer:

var url = 'http://localhost:3000/_oauth/google#access_token=ya29.5HxuYol1Io8JLeGePDznbfkkwu_PC4uodKwG8_1clFYAn9AgdOV1WGpOTNQP3s76HAsn7Y4zWw&token_type=Bearer&expires_in=3600',
    access_token = url.match(/\#(?:access_token)\=([\S\s]*?)\&/)[1];

access_token is:

ya29.5HxuYol1Io8JLeGePDznbfkkwu_PC4uodKwG8_1clFYAn9AgdOV1WGpOTNQP3s76HAsn7Y4zWw

(Directly from the console)

Make use of the URL class in JS:

var token = new URL("http://localhost:3000/_oauth/google#access_token=ya29.5HxuYol1Io8JLeGePDznbfkkwu_PC4uodKwG8_1clFYAn9AgdOV1WGpOTNQP3s76HAsn7Y4zWw&token_type=Bearer&expires_in=3600").hash.split('&').filter(function(el) { if(el.match('access_token') !== null) return true; })[0].split('=')[1];

alert(token);
