item-dsaK123 - request
item-dsaK123*item-Dslw123 - request
item-dsaK123*item-Dslw123*item-ABcd123 - request
item-dsaK132*item-Ddsw532 - request
我如何能够证实这些论点:
- no empty string
- each item must start with item with dash in the middle and unique identifier consist of a-z, A-Z, digit in random order.
- each item can be concatenated to show relationship but it is separated by "*".
有效:
item-dsaK123
item-dsaK123*item-Dslw123
item-dsaK123*item-Dslw123*item-ABcd123
item-dsaK132*item-Ddsw532
in有效:
item-dsaK132+item-Ddsw532*item-ABcd123
item-dsaK132+
