is_url function does not recognise urls with localhost

[fruchtblase]

Hello everyone,

thanks for the great package! I stumbled into a little bug (or desired behavior that isn't documented): if you specifiy an url with localhost, you will get an error.

Maybe the regex in the is_url function needs to be refitted? This comparison of url regexes might help https://mathiasbynens.be/demo/url-regex

Cheers!

library(httr)
library(polite)

polite_POST <- politely(httr::POST, verbose=TRUE) 
polite_POST(url = "http://localhost:3001/api/v1/document")

Error: I can't find an argument containing url. Aborting.
