<補足>
When should I use $location?
Any time your application needs to react to a change in the current URL or if you want to change the current URL in the browser.
What does it not do?
It does not cause a full page reload when the browser URL is changed. To reload the page after changing the URL, use the lower-level API, $window.location.href.
