shortuuid库简介

shortuuid通过使用Python内置的uuid模块生成简洁，明确，URL安全的uuid，然后使用大小写字母和数字将它们转换为base57，并删除类似的字符，如l、1、I、O和0

使用举例

>>> import shortuuid

>>> shortuuid.uuid()

'4jYtG2xGoFvTcNPbnoyCNq'

如果需要生成uui5, 可以将名称( DNS或者 URL ) 传递给函数调用，它将用作产生的UUID的命名空间(UUID.namespace_dns或者 UUID.namespace_url ):

>>> shortuuid.uuid(name="example.com")

'exu3DTbj2ncsn9tLdLWspw'

>>> shortuuid.uuid(name="http://example.com")

'T35fvrnVz6SMSdh9y5hs8c'

还可以生成带密码的安全随机字符串(内部使用 os.urandom())

>>> shortuuid.ShortUUID().random(length=22)

'42qBMavZJGyFmCpA49WgMv'

查看用于生成新uuid的字母表

>>> shortuuid.get_alphabet()

'23456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz'

如果你想使用自定义字母表生成 uuid，客使用set_alphabet():

>>> shortuuid.set_alphabet('LMNPaaaaabcdefgh1230123fghijk')

>>> shortuuid.get_alphabet()

'0123LMNPabcdefghijk'

还支持对已生成的uuid进行加解码

>>> import uuid

>>> u = uuid.uuid4()

>>> u

UUID('8b6b07db-d753-4627-8e1c-4873fe427439')

>>> s = shortuuid.encode(u)

>>> s

'0hMMNLce3gecchjf31N11kkh3MN1fej'

>>> shortuuid.decode(s) == u

True
