示例1: test_validate_arguments

# 需要导入模块: from werkzeug import utils [as 别名]
# 或者: from werkzeug.utils import ArgumentValidationError [as 别名]
def test_validate_arguments(self):
        take_none = lambda: None
        take_two = lambda a, b: None
        take_two_one_default = lambda a, b=0: None

        self.assert_equal(utils.validate_arguments(take_two, (1, 2,), {}), ((1, 2), {}))
        self.assert_equal(utils.validate_arguments(take_two, (1,), {'b': 2}), ((1, 2), {}))
        self.assert_equal(utils.validate_arguments(take_two_one_default, (1,), {}), ((1, 0), {}))

        self.assert_raises(utils.ArgumentValidationError,
            utils.validate_arguments, take_two, (), {})

        self.assert_equal(utils.validate_arguments(take_none, (1, 2,), {'c': 3}), ((), {}))
        self.assert_raises(utils.ArgumentValidationError,
               utils.validate_arguments, take_none, (1,), {}, drop_extra=False)
        self.assert_raises(utils.ArgumentValidationError,

示例2: validate_arguments

# 需要导入模块: from werkzeug import utils [as 别名]
# 或者: from werkzeug.utils import ArgumentValidationError [as 别名]
def validate_arguments(func, args, kwargs, drop_extra=True):
    """Checks if the function accepts the arguments and keyword arguments.
    Returns a new ``(args, kwargs)`` tuple that can safely be passed to
    the function without causing a `TypeError` because the function signature
    is incompatible.  If `drop_extra` is set to `True` (which is the default)
    any extra positional or keyword arguments are dropped automatically.

    The exception raised provides three attributes:

    `missing`
        A set of argument names that the function expected but where
        missing.

    `extra`
        A dict of keyword arguments that the function can not handle but
        where provided.

    `extra_positional`
        A list of values that where given by positional argument but the
        function cannot accept.

    This can be useful for decorators that forward user submitted data to
    a view function::

        from werkzeug.utils import ArgumentValidationError, validate_arguments

        def sanitize(f):
            def proxy(request):
                data = request.values.to_dict()
                try:
                    args, kwargs = validate_arguments(f, (request,), data)
                except ArgumentValidationError:
                    raise BadRequest('The browser failed to transmit all '
                                     'the data expected.')
                return f(*args, **kwargs)
            return proxy

    :param func: the function the validation is performed against.
    :param args: a tuple of positional arguments.
    :param kwargs: a dict of keyword arguments.
    :param drop_extra: set to `False` if you don't want extra arguments
                       to be silently dropped.
    :return: tuple in the form ``(args, kwargs)``.
    """
    parser = _parse_signature(func)
    args, kwargs, missing, extra, extra_positional = parser(args, kwargs)[:5]
    if missing:
        raise ArgumentValidationError(tuple(missing))
    elif (extra or extra_positional) and not drop_extra:
        raise ArgumentValidationError(None, extra, extra_positional)
    return tuple(args), kwargs
