class URI::Generic

Parent:
Object
Included modules:
URI

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:[email protected]").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:[email protected]").opaque #=> "[email protected]"
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"

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.

Synopsis

See ::new.

Description

end

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.

fragment=(v) Show source

Args

v

String

Description

Public setter for the host component v (with validation).

See also URI::Generic.check_host.

Usage

require 'uri'

uri = URI.parse("http://my.example.com")
uri.host = "foo.com"
uri.to_s  #=> "http://foo.com"
hostname() Show source
# File lib/uri/generic.rb, line 644
def hostname
  v = self.host
  /\A\[(.*)\]\z/ =~ v ? $1 : v
end

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.hostname      #=> "::1"
uri.host          #=> "[::1]"
hostname=(v) Show source
# File lib/uri/generic.rb, line 661
def hostname=(v)
  v = "[#{v}]" if /\A\[.*\]\z/ !~ v && /:/ =~ v
  self.host = v
end

Sets the host part of the URI as the argument with brackets for IPv6 addresses.

This method is the same as URI::Generic#host= except the argument can be a bare IPv6 address.

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.
