  • uri/http.rb


The syntax of HTTP URIs is defined in RFC1738 section 3.3.

Note that the Ruby URI library allows HTTP URLs containing usernames and passwords. This is not legal as per the RFC, but used to be supported in Internet Explorer 5 and 6, before the MS04-004 security update. See <URL:support.microsoft.com/kb/834489>.

Public Class Methods

build(args) click to toggle source


Create a new URI::HTTP object from components, with syntax checking.

The components accepted are userinfo, host, port, path, query and fragment.

The components should be provided either as an Array, or as a Hash with keys formed by preceding the component names with a colon.

If an Array is used, the components must be passed in the order [userinfo, host, port, path, query, fragment].


newuri = URI::HTTP.build({:host => 'www.example.com',
  :path> => '/foo/bar'})

newuri = URI::HTTP.build([nil, "www.example.com", nil, "/path",
  "query", 'fragment'])

Currently, if passed userinfo components this method generates invalid HTTP URIs as per RFC 1738.

def self.build(args)
  tmp = Util::make_components_hash(self, args)
  return super(tmp)

Create a new URI::HTTP object from generic URI components as per RFC 2396. No HTTP-specific syntax checking (as per RFC 1738) is performed.

Arguments are scheme, userinfo, host, port, registry, path, opaque, query and fragment, in that order.


uri = URI::HTTP.new(['http', nil, "www.example.com", nil, "/path",
  "query", 'fragment'])
               # File uri/http.rb, line 77
def initialize(*arg)

Public Instance Methods

request_uri() click to toggle source


Returns the full path for an HTTP request, as required by Net::HTTP::Get.

If the URI contains a query, the full path is URI#path + '?' + URI#query. Otherwise, the path is simply URI#path.

               # File uri/http.rb, line 89
def request_uri
  r = path_query
  if r[0] != ?/
    r = '/' + r
