AngularJS: How to clear query parameters in the URL?

My AngularJS application needs to have access to the user's LinkedIn profile. In order to do that I need to redirect the user to a LinkedIn URL which contains a callback redirect_uri parameter which will tell LinkedIn to redirect the user back to my webapp and include a "code" query param in the URL. It's a traditional Oauth 2.0 flow.

Everything works great except that LinkedIn redirects the user back to the following URL:

http://localhost:8080/?code=XXX&state=YYY#/users/123/providers/LinkedIn/social-sites

I would like to remove ?code=XXX&state=YYY from the URL in order to make it clean. The user does not need to see the query parameters I received from LinkedIn redirect.

I tried $location.absUrl($location.path() + $location.hash()).replace(), but it keep the query params in the URL.

I am also unable to extract the query parameters, e.g. "code", using ($location.search()).code. It seems like having ? before # in the URL above is tricking Angular.

I use

$location.search('key', null)

As this not only deletes my key but removes it from the visibility on the URL.

I ended up getting the answer from AngularJS forum. See this thread for details

The link is to a Google Groups thread, which is difficult to read and doesn't provide a clear answer. To remove URL parameters use

$location.url($location.path());

You can delete a specific query parameter by using:

delete $location.$$search.nameOfParameter;

Or you can clear all the query params by setting search to an empty object:

$location.$$search = {};

To clear an item delete it and call $$compose 

    if ($location.$$search.yourKey) {
        delete $location.$$search.yourKey;
        $location.$$compose();
    }

derived from angularjs source : https://github.com/angular/angular.js/blob/c77b2bcca36cf199478b8fb651972a1f650f646b/src/ng/location.js#L419-L443

At the time of writing, and as previously mentioned by @Bosh, html5mode must be true in order to be able to set $location.search() and have it be reflected back into the window’s visual URL.

See https://github.com/angular/angular.js/issues/1521 for more info.

But if html5mode is true you can easily clear the URL’s query string with:

$location.search('');

or

$location.search({});

This will also alter the window’s visual URL.

(Tested in AngularJS version 1.3.0-rc.1 with html5Mode(true).)

Need to make it work when html5mode = false?

All of the other answers work only when Angular's html5mode is true. If you're working outside of html5mode, then $location refers only to the "fake" location that lives in your hash -- and so $location.search can't see/edit/fix the actual page's search params.

Here's a workaround, to be inserted in the HTML of the page before angular loads:

<script>
  if (window.location.search.match("code=")){
    var newHash = "/after-auth" + window.location.search;
    if (window.history.replaceState){
      window.history.replaceState( {}, "", window.location.toString().replace(window.location.search, ""));
    }
    window.location.hash = newHash;
  }
</script>

If you are using routes parameters just clear $routeParams 

$routeParams= null;

How about just setting the location hash to null

$location.hash(null);
