How to obtain values of request variables using Python and Flask

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 dont 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.

You can get posted form data from request.form and query string data from request.args.

myvar =  request.form[myvar]

myvar = request.args[myvar]

Adding more to Jasons more generalized way of retrieving the POST data or GET data

from flask_restful import reqparse

def parse_arg_from_requests(arg, **kwargs):
    parse = reqparse.RequestParser()
    parse.add_argument(arg, **kwargs)
    args = parse.parse_args()
    return args[arg]

form_field_value = parse_arg_from_requests(FormFieldValue)
