Argument with multiple occurrences

[sylvainvivien]

Like Google webapp : http://code.google.com/intl/fr/appengine/docs/python/tools/webapp/req...
it could be nice to have an "allow_multiple=True" in the get_argument
function. (or a get_all_argument)

Example : currently, if self.request.arguments returns {'key1':
['val3'], 'key2': ['val1', 'val2']}
self.get_argument(key2) will return 'val2'

and with an allow_multiple=True :
self.get_argument(key2, allow_multiple=True) it should return ['val1',
'val2']

I know it's possible to do : self.request.arguments['key2'], but here
we missed all unicode/utf-8 functions.

Another thing, in my example : {'key1': ['val3'], 'key2': ['val1',
'val2']}
For key1, that is not "multiple", self.request.arguments should return
{'key1': 'val3', 'key2': ['val1', 'val2']}.
i.e. : key1 should not be a list but a value.

I think it is the same issue with self.request.files, that always
returns a list even if there is only one file.

I've added a patch for this jehiah/tornado@cbe2eeb

My approach is to add a self.get_arguments() method modeled after self.get_argument()

RequestHandler now has a get_arguments() method.
