Signature de la méthode url_value_preprocessor

def url_value_preprocessor(self, f: Callable[[Optional[str], Optional[dict]], NoneType]) -> Callable[[Optional[str], Optional[dict]], NoneType] 

Description

url_value_preprocessor.__doc__

Register a URL value preprocessor function for all view
        functions in the application. These functions will be called before the
        :meth:`before_request` functions.

        The function can modify the values captured from the matched url before
        they are passed to the view. For example, this can be used to pop a
        common language code value and place it in ``g`` rather than pass it to
        every view.

        The function is passed the endpoint name and values dict. The return
        value is ignored.
