AngularJs: How to cache $http properly?

问题:

I've enabled cache in my $http request and now the callback for success only runs the first time. I'm wondering if this is expected or there's something I need to know about caching $http ?

This is what I've been trying:

$http.get('/foo/bar', { cache: true })
.success(function(data){
  // does foo
})
.error(function(){
  // uh oh
});

Let's say I've processed the data once, but there's also other commands that I'd like to run, every time. So, if it's true the data is cached or already available I don't want to repeat myself, but let's say, If I'm opening and closing elements with animations, where should this go ?!

Thanks for looking!

You can use the $cacheFactory object. See : http://docs.angularjs.org/api/ng.$cacheFactory

You can cache $http request like that :

var $httpDefaultCache = $cacheFactory.get('$http');

If you want to retrieve a specific url in cache do :

var cachedData = $httpDefaultCache.get('http://myserver.com/foo/bar/123');

$You can clear the cache too :

$httpDefaultCache.remove('http://myserver.com/foo/bar/123');

or :

$httpDefaultCache.removeAll();

I'm pretty sure that the new GET request isn't running so no corresponding success callbacks are called.
