class URI::HTTP

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>.

Constants

COMPONENT: An Array of the available components for URI::HTTP.
DEFAULT_PORT: A Default port of 80 for URI::HTTP.

Public Class Methods

build (args)

Source

# File lib/uri/http.rb, line 59
def self.build(args)
  tmp = Util.make_components_hash(self, args)
  super(tmp)
end

Description¶ ↑

Creates 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].

Example:

uri = URI::HTTP.build(host: 'www.example.com', path: '/foo/bar')

uri = 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.

Calls superclass method URI::Generic::build

Public Instance Methods

authority ()

Source

# File lib/uri/http.rb, line 109
def authority
  if port == default_port
    host
  else
    "#{host}:#{port}"
  end
end

Description¶ ↑

Returns the authority for an HTTP uri, as defined in www.rfc-editor.org/rfc/rfc3986#section-3.2.

Example:

URI::HTTP.build(host: 'www.example.com', path: '/foo/bar').authority #=> "www.example.com"
URI::HTTP.build(host: 'www.example.com', port: 8000, path: '/foo/bar').authority #=> "www.example.com:8000"
URI::HTTP.build(host: 'www.example.com', port: 80, path: '/foo/bar').authority #=> "www.example.com"

check_host (v)

Source

# File lib/uri/http.rb, line 65
def check_host(v)
  ret = super

  if ret && v.empty?
    raise InvalidComponentError,
      "bad component(expected host component): #{v}"
  end

  ret
end

Do not allow empty host names, as they are not allowed by RFC 3986.

Calls superclass method URI::Generic#check_host

origin ()

Source

# File lib/uri/http.rb, line 131
def origin
  "#{scheme}://#{authority}"
end

Description¶ ↑

Returns the origin for an HTTP uri, as defined in www.rfc-editor.org/rfc/rfc6454.

Example:

URI::HTTP.build(host: 'www.example.com', path: '/foo/bar').origin #=> "http://www.example.com"
URI::HTTP.build(host: 'www.example.com', port: 8000, path: '/foo/bar').origin #=> "http://www.example.com:8000"
URI::HTTP.build(host: 'www.example.com', port: 80, path: '/foo/bar').origin #=> "http://www.example.com"
URI::HTTPS.build(host: 'www.example.com', path: '/foo/bar').origin #=> "https://www.example.com"

request_uri ()

Source

# File lib/uri/http.rb, line 89
def request_uri
  return unless @path

  url = @query ? "#@path?#@query" : @path.dup
  url.start_with?(?/.freeze) ? url : ?/ + url
end

Description¶ ↑

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.

Example:

uri = URI::HTTP.build(path: '/foo/bar', query: 'test=true')
uri.request_uri #  => "/foo/bar?test=true"
