用于验证URL中“ /”的正则表达式

Question

I am writing a web application in golang. I am using regular expression to validate the URL. But I am not able to include '/' in the URL validation.

var validPath = regexp.MustCompile("^/(home|about)/(|[a-zA-Z0-9]+)$")

The above URL takes '/home/', '/about/' but could not make for '/'.

Could anyone please help me on this?

Answer 1

Why not adding that case as an alternative:

"^/$|(/(home|about)/(|[a-zA-Z0-9]+)$)"
