shortuuid庫簡介

shortuuid通過使用Python內置的uuid模塊生成簡潔，明確，URL安全的uuid，然后使用大小寫字母和數字將它們轉換為base57，並刪除類似的字符，如l、1、I、O和0

 

使用舉例

>>> import shortuuid

>>> shortuuid.uuid()

'4jYtG2xGoFvTcNPbnoyCNq'

 

如果需要生成uui5, 可以將名稱( DNS或者 URL ) 傳遞給函數調用，它將用作產生的UUID的命名空間(UUID.namespace_dns或者 UUID.namespace_url ):

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

'exu3DTbj2ncsn9tLdLWspw'

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

'T35fvrnVz6SMSdh9y5hs8c'

 

還可以生成帶密碼的安全隨機字符串(內部使用 os.urandom())

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

'42qBMavZJGyFmCpA49WgMv'

 

查看用於生成新uuid的字母表

>>> shortuuid.get_alphabet()

'23456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz'

 

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

>>> shortuuid.set_alphabet('LMNPaaaaabcdefgh1230123fghijk')

>>> shortuuid.get_alphabet()

'0123LMNPabcdefghijk'

 

還支持對已生成的uuid進行加解碼

>>> import uuid

>>> u = uuid.uuid4()

>>> u

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

>>> s = shortuuid.encode(u)

>>> s

'0hMMNLce3gecchjf31N11kkh3MN1fej'

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

True
