compiler库的使用方法

1、基础用法

使用

from vlde import Validator

v = Validator(return_format='object')

result = v.set_rules('hello', 'required|dict|max_length:3')

if result.status is False:

   print('\n'.join(result.error))

或者捕获异常：

from vlde import ValidateError, Validator

v = Validator(return_format='exception')

try:

   v.set_rules('hello', 'required|dict')

except ValidateError as e:

   print(e)
