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 78 def domain(tld_length = 1) return nil unless named_host?(host) host.split('.').last(1 + tld_length).join('.') end
Returns the host for this request, such as example.com.
# File lib/action_dispatch/http/url.rb, line 34 def host raw_host_with_port.sub(%r:\d+$/, '') end
Returns a host:port string for this request, such as “example.com” or “example.com:8080”.
# File lib/action_dispatch/http/url.rb, line 40 def host_with_port "#{host}#{port_string}" end
Returns the port number of this request as an integer.
# File lib/action_dispatch/http/url.rb, line 45 def port if raw_host_with_port =~ %r:(\d+)$/ $1.to_i else standard_port end end
Returns a 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 68 def port_string port == standard_port ? '' : ":#{port}" end
Returns ‘https://’ if this is an SSL request and ‘http://’ otherwise.
# File lib/action_dispatch/http/url.rb, line 15 def protocol ssl? ? 'https://' : 'http://' end
Returns the host for this request, such as “example.com”.
# File lib/action_dispatch/http/url.rb, line 25 def raw_host_with_port if forwarded = env["HTTP_X_FORWARDED_HOST"] forwarded.split(%r,\s?/).last else env['HTTP_HOST'] || "#{env['SERVER_NAME'] || env['SERVER_ADDR']}:#{env['SERVER_PORT']}" end end
Returns the request URI, accounting for server idiosyncrasies. WEBrick includes the full URL. IIS leaves REQUEST_URI blank.
# File lib/action_dispatch/http/url.rb, line 100 def request_uri ActiveSupport::Deprecation.warn "Using #request_uri is deprecated. Use fullpath instead.", caller fullpath end
Returns ‘https’ if this is an SSL request and ‘http’ otherwise.
# File lib/action_dispatch/http/url.rb, line 10 def scheme ssl? ? 'https' : 'http' end
# File lib/action_dispatch/http/url.rb, line 72 def server_port @env['SERVER_PORT'].to_i end
Is this an SSL request?
# File lib/action_dispatch/http/url.rb, line 20 def ssl? @env['HTTPS'] == 'on' || @env['HTTP_X_FORWARDED_PROTO'] == 'https' end
Returns the standard port number for this request’s protocol.
# File lib/action_dispatch/http/url.rb, line 54 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 62 def standard_port? port == standard_port end
# File lib/action_dispatch/http/url.rb, line 94 def subdomain(tld_length = 1) 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 88 def subdomains(tld_length = 1) return [] unless named_host?(host) parts = host.split('.') parts[0..-(tld_length+2)] end
Returns the complete URL used for this request.
