Constants

An Array of the available components for URI::Generic

Attributes
Read

returns the scheme component of the URI.

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

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"
Read

returns the port component of the URI.

URI("http://foo/bar/baz").port #=> "80"

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

returns the path component of the URI.

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

returns the query component of the URI.

URI("http://foo/bar/baz?search=FooBar").query #=> "search=FooBar"
Read

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)
Read

returns the fragment component of the URI.

URI("http://foo/bar/baz?search=FooBar#ponies").fragment #=> "ponies"
Class Methods

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

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.

Components of the URI in the order.

Returns default port

Args

scheme

Protocol scheme, i.e. ‘http’,‘ftp’,‘mailto’ and so on.

userinfo

User name and password, i.e. ‘sdmitry:bla’

host

Server host name

port

Server port

registry

Registry of naming authorities.

path

Path on server

opaque

Opaque part

query

Query data

fragment

A part of URI after ‘#’ sign

parser

Parser for internal use [URI::DEFAULT_PARSER by default]

arg_check

Check arguments [false by default]

Description

Creates a new URI::Generic instance from “generic” components without check.

Instance Methods
An alias for merge
An alias for route_from

Compares to URI’s

An alias for absolute?

Checks if URI is an absolute one

check the host v component for RFC2396 compliance and against the URI::Parser Regexp for :HOST

Can not have a registry or opaque component defined, with a host component defined.

check the opaque v component for RFC2396 compliance and against the URI::Parser Regexp for :OPAQUE

Can not have a host, port, user or path component defined, with an opaque component defined.

check the password v component for RFC2396 compliance and against the URI::Parser Regexp for :USERINFO

Can not have a registry or opaque component defined, with a user component defined.

check the path v component for RFC2396 compliance and against the URI::Parser Regexp for :ABS_PATH and :REL_PATH

Can not have a opaque component defined, with a path component defined.

check the port v component for RFC2396 compliance and against the URI::Parser Regexp for :PORT

Can not have a registry or opaque component defined, with a port component defined.

check the scheme v component against the URI::Parser Regexp for :SCHEME

check the user v component for RFC2396 compliance and against the URI::Parser Regexp for :USERINFO

Can not have a registry or opaque component defined, with a user component defined.

check the user and password.

If password is not provided, then user is split, using URI::Generic.split_userinfo, to pull user and +password.

see also URI::Generic.check_user, URI::Generic.check_password

Args

v

URI or String

Description

attempt to parse other URI +oth+
return [parsed_oth, self]

Usage

require 'uri'

uri = URI.parse("http://my.example.com")
uri.coerce("http://foo.com")
#=> [#<URI::HTTP:0x00000000bcb028 URL:http://foo.com/>, #<URI::HTTP:0x00000000d92178 URL:http://my.example.com>]

Components of the URI in the order.

returns an Array of the components defined from the COMPONENT Array

Returns default port

No documentation available

escapes ‘user:password’ v based on RFC 1738 section 3.1

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.

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.

check the fragment v component against the URI::Parser Regexp for :FRAGMENT

Args

v

String

Description

public setter for the fragment component v. (with validation)

Usage

require 'uri'

uri = URI.parse("http://my.example.com/?id=25#time=1305212049")
uri.fragment = "time=1305212086"
# =>  "time=1305212086"

#=> #<URI::HTTP:0x000000007a81f8 URL:http://my.example.com/?id=25#time=1305212086>
No documentation available

Checks if URI has a path

Args

v

String

Description

uri
#=> #<URI::HTTP:0x000000008e89e8 URL:http://foo.com>

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]”

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(“foo/bar”) p u.to_s #=> “foo/bar” u.hostname = “::1” p u.to_s #=> “[::1]/bar

If the argument seems IPv6 address, it is wrapped by brackets.
