How to make an alias for whois to feed it urls, not domains?

Question

linux

I want to make it possible to give the whois command any URL, and not just a domain.
Came up with homies 2 options:

alias h="echo \$2 | awk -F/ '{print \$3}'|xargs /usr/bin/whois"

alias h='echo $2 | sed -E "s~^http://([^/]+)/~\1~"|xargs /usr/bin/whois'

Neither one nor the other does not work in the alias. How to adapt them for alias?
PS I'm reluctant to make a script: I'm used to transferring .aliasrc everywhere, and then copy some additional script.
