Regex - IIS URL rewrite pagination

Question

My URL looks like this:

domain.com/12345/some-product-category

and with the optional pagination:

domain.com/12345-2/some-product-category

so far my pattern looks like this:

^([0-9]{5})(-[0-9]+)?/([_0-9a-z-]*)

but the capture {R:2} return "-2" and not "2" as wanted... How do I fix this?

Answer 1

您可以使用如下表达式：

^(\d{5})(?:-(\d+))?/([\w-]*)

Answer 2

because you've placed in your group -[0-9]+ and not [0-9]+ . You should take off minus sign from group.
Try this regex ^([0-9]{5})(-([0-9]+))?/([_0-9a-z-]*) and take group 3.
