python方法的参数验证库，作为pythonic装饰器
pyvalidate的Python项目详细描述
使用以下参数验证可调用的输入参数：
param: arg_types: list of types, Required argument's types & counts in order param: deny_match list of string ,regex pattern, if any argument matches with the pattern, exception raises param: requires: list of fields to check for mandatory param: deny: string ,regex pattern, if any parameter matches with the pattern, exception raises param: deny_except: string ,regex pattern for excluding fields from deny param: types: dict of key:name and value:type to check for types, if mismatch it will be raises exception param: values: dict of key:name and value:regex pattern to check the values, & fire exception if mismatch param: ignore: string ,regex pattern of parameters to filter param: defaults: dict of key:name and value:default_value
例外情况：
raise: MandatoryException: if any param in requires does not provided raise: ArgumentException: if arguments are invalid , short or mismatch type. raise: DenialException: if found param in deny list raise: ParameterTypeException: if parameter types invalid raise: ParameterValueException: if values are not in correct format
示例：
from pyvalidate import validate, ValidationException
@validate(arg_types=[int, str, str],
deny_match=['xxx', 'tiktik'],
requires=['phone'],
deny='query',
deny_except='query2',
types={'phone':str, 'address':str, 'age':int},
values={'phone':'^\d*$'},
ignore='age',
defaults={'address':'nothing'})
def add_person(serial, firstname, lastname, phone=None, address=None, age=None, **kw):
print 'adding person "%s:%s %s:%s" with serial: %s:%s phone: %s:%s address: %s:%s age:%s:%s' % (firstname, type(firstname),
lastname, type(lastname),
serial, type(serial),
phone,
type(phone),
address,
type(address),
age,
type(age))
def test(*args, **kwargs):
try:
add_person(*args, **kwargs)
except ValidationException as ex:
print ex.message
def main():
test(12, "Vahid", "Mardani", phone="09122451075", address="Tehran")
test("12", "Vahid", "Mardani", phone='+9122451075', address="Tehran")
test("12", "Vahid", "Mardani", phone='1')

test("12", "xxx", "Mardani", phone='')
test("12", "", "Mardani",)
test("12", "", "Mardani", phone='1', query='123')
test("12", "", "Mardani", phone='1', query2='123')
test("12", "", "Mardani", phone='1', age='123')
if __name__ == '__main__':
