domain(tld_length = @@tld_length) Show source

Returns the domain part of a host, such as “rubyonrails.org” in “www.rubyonrails.org”. You can specify a different tld_length, such as 2 to catch rubyonrails.co.uk in “www.rubyonrails.co.uk”.

# File actionpack/lib/action_dispatch/http/url.rb, line 228
def domain(tld_length = @@tld_length)
  ActionDispatch::Http::URL.extract_domain(host, tld_length)
end

host() Show source

Returns the host for this request, such as example.com.

# File actionpack/lib/action_dispatch/http/url.rb, line 176
def host
  raw_host_with_port.sub(/:\d+$/, '')
end

host_with_port() Show source

Returns a host:port string for this request, such as “example.com” or “example.com:8080”.

# File actionpack/lib/action_dispatch/http/url.rb, line 182
