使用itsdangerous生成有时间限制的token

>>> from itsdangerous import TimedJSONWebSignatureSerializer as Serializer
# 设置加密密钥为“key”，限制时间为60秒
>>> s = Serializer("key", 60)
>>> token = s.dumps({'id':'12345'}).decode('utf-8')
>>> s.loads(token.encode('utf-8'))
{'id': '12345'}
# 过60秒后
>>> s.loads(token.encode('utf-8'))
---------------------------------------------------------------------------
