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 lib/action_dispatch/http/url.rb, line 151 def domain(tld_length = @@tld_length) ActionDispatch::Http::URL.extract_domain(host, tld_length) end
Returns the host for this request, such as example.com.
# File lib/action_dispatch/http/url.rb, line 99 def host raw_host_with_port.sub(/:\d+$/, '') end
Returns a host:port string for this request, such as “example.com” or “example.com:8080”.
# File lib/action_dispatch/http/url.rb, line 105 def host_with_port "#{host}#{port_string}" end
Returns a number port suffix like 8080 if the port number of this request is not the default HTTP port 80 or HTTPS port 443.
# File lib/action_dispatch/http/url.rb, line 135 def optional_port standard_port? ? nil : port end
Returns the port number of this request as an integer.
# File lib/action_dispatch/http/url.rb, line 110 def port @port ||= begin if raw_host_with_port =~ /:(\d+)$/ $1.to_i else standard_port end end end
Returns a string port suffix, including colon, like “:8080” if the port number of this request is not the default HTTP port 80 or HTTPS port 443.
# File lib/action_dispatch/http/url.rb, line 141 def port_string standard_port? ? '' : ":#{port}" end
Returns ‘https://’ if this is an SSL request and ‘http://’ otherwise.
# File lib/action_dispatch/http/url.rb, line 85 def protocol @protocol ||= ssl? ? 'https://' : 'http://' end
Returns the host for this request, such as “example.com”.
# File lib/action_dispatch/http/url.rb, line 90 def raw_host_with_port if forwarded = env["HTTP_X_FORWARDED_HOST"] forwarded.split(/,\s?/).last else env['HTTP_HOST'] || "#{env['SERVER_NAME'] || env['SERVER_ADDR']}:#{env['SERVER_PORT']}" end end
# File lib/action_dispatch/http/url.rb, line 145 def server_port @env['SERVER_PORT'].to_i end
Returns the standard port number for this request’s protocol.
# File lib/action_dispatch/http/url.rb, line 121 def standard_port case protocol when 'https://' then 443 else 80 end end
Returns whether this request is using the standard port
# File lib/action_dispatch/http/url.rb, line 129 def standard_port? port == standard_port end
Returns all the subdomains as a string, so "dev.www" would be returned for “dev.www.rubyonrails.org”. You can specify a different tld_length, such as 2 to catch "www" instead of "www.rubyonrails" in “www.rubyonrails.co.uk”.
# File lib/action_dispatch/http/url.rb, line 167 def subdomain(tld_length = @@tld_length) subdomains(tld_length).join(".") end
Returns all the subdomains as an array, so ["dev", "www"] would be returned for “dev.www.rubyonrails.org”. You can specify a different tld_length, such as 2 to catch ["www"] instead of ["www", "rubyonrails"] in “www.rubyonrails.co.uk”.
# File lib/action_dispatch/http/url.rb, line 159 def subdomains(tld_length = @@tld_length) ActionDispatch::Http::URL.extract_subdomains(host, tld_length) end
Returns the complete URL used for this request.
