How to obtain values of request variables using Python and Flask [duplicate]

Question

If you want to retrieve POST data:

first_name = request.form.get("firstname")

If you want to retrieve GET (query string) data:

first_name = request.args.get("firstname")

Or if you don’t care/know whether the value is in the query string or in the post data:

first_name = request.values.get("firstname")

request.values is a CombinedMultiDict that combines Dicts from request.form and request.args.
