Generic show all
Defined in:
lib/rubygems/vendor/uri/lib/uri/http.rb

Overview

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

Note that the Ruby Gem::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>.

Class Method Details

.build(args) ⇒ Object

Description

Creates a new Gem::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 = Gem::URI::HTTP.build(host: 'www.example.com', path: '/foo/bar')

uri = Gem::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.

Instance Method Details

#authority ⇒ Object

Description

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

Example:

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

    host
  else
    "#{host}:#{port}"
  end
end

#origin ⇒ Object

Description

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

Example:

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

def origin
  "#{scheme}://#{authority}"
end

#request_uri ⇒ Object

Description

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

If the Gem::URI contains a query, the full path is Gem::URI#path + ‘?’ + Gem::URI#query. Otherwise, the path is simply Gem::URI#path.

Example:

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