Error getting state from the storage

[dhawkmoon]

Hello,

Thank you for great library. I've been trying to set auth with Instagram api and faced a little problem: instagram api sends me such parameters on redirect:

?state=07d17d32-aac7-421f-91fc-7a48f060c7e1#access_token=4708552857.7c4d118.2765b774374d4e5c96cd04f142ed086f

Since the query string contains both '#' and '?' symbols in different positions, utils.getResponseFromURL function fails to parse string properly and as a result I've got error of getting state from the storage.

You could solve it by changing

jso/src/utils.js

Lines 29 to 36 in 543ddde

	utils.getResponseFromURL = function (url) {
	if (url.indexOf('#') !== -1) {
	return utils.parseQueryString(url.substring(url.indexOf('#')+1))
	} else if (url.indexOf('?') !== -1) {
	return utils.parseQueryString(url.substring(url.indexOf('?')+1))
	}
	return {}
	}

to :

utils.getResponseFromURL = function (url) {
  var u = new URL(url);
  var hash = {};
  var search = {};
  if (u.hash.indexOf('#') !== -1) {
    hash = utils.parseQueryString(u.hash.substring(u.hash.indexOf('#')+1))
  }
  if (u.search.indexOf('?') !== -1) {
    search = utils.parseQueryString(u.search.substring(u.search.indexOf('?')+1))
  }
  return Object.assign({}, hash, search)
}

Which will then correctly parse both ? and # portions from a given url:

The only thing I wouldn't like about my solution though would be that Object.assign is not available in IE and Opera for Android. And the CI didn't catch this. Unless babel/webpack takes care of this when building? @andreassolberg
