Object
An Array of the available components for URI::Generic
A Default port of nil for URI::Generic
returns the fragment component of the URI
.
URI("http://foo/bar/baz?search=FooBar#ponies").fragment #=> "ponies"
returns the host component of the URI
.
URI("http://foo/bar/baz").host #=> "foo"
It returns nil if no host component.
URI("mailto:foo@example.org").host #=> nil
The component doesn't contains the port number.
URI("http://foo:8080/bar/baz").host #=> "foo"
Since IPv6 addresses are wrapped by brackets in URIs, this method returns IPv6 addresses wrapped by brackets. This form is not appropriate to pass socket methods such as TCPSocket.open. If unwrapped host names are required, use “hostname” method.
URI("http://[::1]/bar/baz").host #=> "[::1]" URI("http://[::1]/bar/baz").hostname #=> "::1"
returns the opaque part of the URI
.
URI("mailto:foo@example.org").opaque #=> "foo@example.org"
Portion of the path that does make use of the slash '/'. The path typically refers to the absolute path and the opaque part. (See RFC2396 Section 3 and 5.2.)
returns the port component of the URI
.
URI("http://foo/bar/baz").port #=> "80" URI("http://foo:8080/bar/baz").port #=> "8080"
returns the query component of the URI
.
URI("http://foo/bar/baz?search=FooBar").query #=> "search=FooBar"

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.

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

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.

extract the host part of the URI
and unwrap brackets for IPv6 addresses.
This method is same as URI::Generic#host
except brackets for IPv6 (and future IP) addresses are removed.
u = URI("http://[::1]/bar") p u.hostname #=> "::1" p u.host #=> "[::1]"
# File uri/generic.rb, line 652 def hostname v = self.host /\A\[(.*)\]\z/ =~ v ? $1 : v end
set the host part of the URI
as the argument with brackets for IPv6 addresses.
This method is same as URI::Generic#host=
except the argument can be bare IPv6 address.
u = URI("http://foo/bar") p u.to_s #=> "http://foo/bar" u.hostname = "::1" p u.to_s #=> "http://[::1]/bar"
If the argument seems IPv6 address, it is wrapped by brackets.

require 'uri' URI("HTTP://my.EXAMPLE.com").normalize #=> #<URI::HTTP http://my.example.com/>
Normalization here means:
scheme and host are converted to lowercase,

Destructive version of normalize
