Default $http
params serializer that converts objects to strings
according to the following rules:
{'foo': 'bar'}
results in foo=bar
{'foo': Date.now()}
results in foo=2015-04-01T09%3A50%3A49.262Z
(toISOString()
and encoded representation of a Date object){'foo': ['bar', 'baz']}
results in foo=bar&foo=baz
(repeated key for each array element){'foo': {'bar':'baz'}}
results in foo=%7B%22bar%22%3A%22baz%22%7D"
(stringified and encoded representation of an object)Note that serializer will sort the request parameters alphabetically.
