• 生成自定义位数的随机字符串

  :syntax: generate_rnd_string(n:int=6, fmt:str='O') -> str

  :param: n 生成的字符串的位数

  :param: fmt 最终生成的字符串样式 L:全部小写; U:全部大写; N:全部数字; O: 随机字符串

  :return: string

  >>> from pyhelper.helper import generate_rnd_string
  >>> print(generate_rnd_string())
  >>> "w9y5Yk"

  :param sequence: 序列号

  :return: int

  >>> from pyhelper.helper import snow_flake
  >>> print(snow_flake())
  >>> 1448838354849370112
  >>> print(snow_flake(1,2,0))
  >>> 1448838475976679424

  :param secret: 密钥

  :param expire: 有效时间,默认7200秒

  :return: 返回编码后的数据

  >>> from pyhelper.helper import jwt_encode
  >>> raw = {"uid":"123456"}
  >>> print(jwt_encode(raw, secret='3ndbwa4GYr', expire=7200))
  >>> "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1aWQiOiIxMjM0NTYiLCJleHAiOjE2MzQ1MTc1NDh9.Mtn-o9wtx-AsvpEXqQx8XQ_AFd7-EsRMHjGED1fcq34"
