class URI::Generic

Base class for all URI classes. Implements generic URI syntax as per RFC 2396.

Constants

COMPONENT

An Array of the available components for URI::Generic.

DEFAULT_PORT

A Default port of nil for URI::Generic.

Attributes

fragment [R]

Returns the fragment component of the URI.

URI("http://foo/bar/baz?search=FooBar#ponies").fragment #=> "ponies"
host [R]

Returns the host component of the URI.

URI("http://foo/bar/baz").host #=> "foo"

It returns nil if no host component exists.

URI("mailto:foo@example.org").host #=> nil

The component does not contain the port number.

URI("http://foo:8080/bar/baz").host #=> "foo"

Since IPv6 addresses are wrapped with brackets in URIs, this method returns IPv6 addresses wrapped with brackets. This form is not appropriate to pass to socket methods such as TCPSocket.open. If unwrapped host names are required, use the hostname method.

URI("http://[::1]/bar/baz").host     #=> "[::1]"
URI("http://[::1]/bar/baz").hostname #=> "::1"
opaque [R]

Returns the opaque part of the URI.

URI("mailto:foo@example.org").opaque #=> "foo@example.org"
URI("http://foo/bar/baz").opaque     #=> nil

The portion of the path that does not make use of the slash ‘/’. The path typically refers to an absolute path or an opaque part. (See RFC2396 Section 3 and 5.2.)

path [R]

Returns the path component of the URI.

URI("http://foo/bar/baz").path #=> "/bar/baz"
port [R]

Returns the port component of the URI.

URI("http://foo/bar/baz").port      #=> 80
URI("http://foo:8080/bar/baz").port #=> 8080
query [R]

Returns the query component of the URI.

URI("http://foo/bar/baz?search=FooBar").query #=> "search=FooBar"
scheme [R]

Returns the scheme component of the URI.

URI("http://foo/bar/baz").scheme #=> "http"

Public Class Methods

build (args)

Synopsis ↑

See ::new.

Description ↑

Creates a new URI::Generic instance from components of URI::Generic with check. Components are: scheme, userinfo, host, port, registry, path, opaque, query, and fragment. You can provide arguments either by an Array or a Hash. See ::new for hash keys to use or for order of array items.

# File lib/uri/generic.rb, line 116
def self.build(args)
  if args.kind_of?(Array) &&
      args.size == ::URI::Generic::COMPONENT.size
    tmp = args.dup
  elsif args.kind_of?(Hash)
    tmp = ::URI::Generic::COMPONENT.collect do |c|
      if args.include?(c)
        args[c]
      else
        nil
      end
    end
  else
    component = self.class.component rescue ::URI::Generic::COMPONENT
    raise ArgumentError,
    "expected Array of or Hash of components of #{self.class} (#{component.join(', ')})"
  end

  tmp << nil
  tmp << true
  return self.new(*tmp)
end
build2 (args)

Synopsis ↑

See ::new.

Description ↑

At first, tries to create a new URI::Generic instance using URI::Generic::build. But, if exception URI::InvalidComponentError is raised, then it does URI::Escape.escape all URI components and tries again.

find_proxy (env=ENV)

Returns a proxy URI. The proxy URI is obtained from environment variables such as http_proxy, ftp_proxy, no_proxy, etc. If there is no proper proxy, nil is returned.

If the optional parameter env is specified, it is used instead of ENV.

Note that capitalized variables (HTTP_PROXY, FTP_PROXY, NO_PROXY, etc.) are examined, too.

But http_proxy and HTTP_PROXY is treated specially under CGI environment. It’s because HTTP_PROXY may be set by Proxy: header. So HTTP_PROXY is not used. http_proxy is not used too if the variable is case insensitive. CGI_HTTP_PROXY can be used instead.

end
hostname ()

Extract the host part of the URI and unwrap brackets for IPv6 addresses.

This method is the same as URI::Generic#host except brackets for IPv6 (and future IP) addresses are removed.

uri = URI("http://[::1]/bar")

uri.host          #=> "[::1]"

uri = URI("http://foo/bar")
uri.hostname = "::1"
uri.to_s  #=> "http://[::1]/bar"

If the argument seems to be an IPv6 address, it is wrapped with brackets.

# File lib/uri/generic.rb, line 671
