Module: Bundler::URI

Like .decode_www_form_component, except that '+' is preserved.

Returns name/value pairs derived from the given string str, which must be an ASCII string.

The method may be used to decode the body of Net::HTTPResponse object res for which res['Content-Type'] is 'application/x-www-form-urlencoded'.

The returned data is an array of 2-element subarrays; each subarray is a name/value pair (both are strings). Each returned string has encoding enc, and has had invalid characters removed via {String#scrub}.

A simple example:

Bundler::URI.decode_www_form('foo=0&bar=1&baz')
# => [["foo", "0"], ["bar", "1"], ["baz", ""]]

The returned strings have certain conversions, similar to those performed in .decode_www_form_component:

Bundler::URI.decode_www_form('f%23o=%2F&b-r=%24&b+z=%40')
# => [["f#o", "/"], ["b-r", "$"], ["b z", "@"]]

The given string may contain consecutive separators:

Bundler::URI.decode_www_form('foo=0&&bar=1&&baz=2')
# => [["foo", "0"], ["", ""], ["bar", "1"], ["", ""], ["baz", "2"]]

A different separator may be specified:

Bundler::URI.decode_www_form('foo=0--bar=1--baz', separator: '--')
# => [["foo", "0"], ["bar", "1"], ["baz", ""]]

Returns a string decoded from the given URL-encoded string str.

The given string is first encoded as Encoding::ASCII-8BIT (using String#b), then decoded (as below), and finally force-encoded to the given encoding enc.

The returned string:

• Preserves:

  • Characters '*', '.', '-', and '_'.

  • Character in ranges 'a'..'z', 'A'..'Z', and '0'..'9'.

  Example:

  Bundler::URI.decode_www_form_component('*.-_azAZ09')
  # => "*.-_azAZ09"

• Converts:

  • Character '+' to character ' '.

  • Each “percent notation” to an ASCII character.

  Example:

  Bundler::URI.decode_www_form_component('Herearesomepunctuationcharacters%3A+%2C%3B%3F%3A')
  # => "Here are some punctuation characters: ,;?:"

Related: .decode_uri_component (preserves '+').

Like .encode_www_form_component, except that ' ' (space) is encoded as '%20' (instead of '+').

Returns a URL-encoded string derived from the given Enumerable enum.

The result is suitable for use as form data for an HTTP request whose Content-Type is 'application/x-www-form-urlencoded'.

The returned string consists of the elements of enum, each converted to one or more URL-encoded strings, and all joined with character '&'.

Simple examples:

Bundler::URI.encode_www_form([['foo', 0], ['bar', 1], ['baz', 2]])
# => "foo=0&bar=1&baz=2"
Bundler::URI.encode_www_form({foo: 0, bar: 1, baz: 2})
# => "foo=0&bar=1&baz=2"

The returned string is formed using method .encode_www_form_component, which converts certain characters:

Bundler::URI.encode_www_form('f#o': '/', 'b-r': '$', 'b z': '@')
# => "f%23o=%2F&b-r=%24&b+z=%40"

When enum is Array-like, each element ele is converted to a field:

• If ele is an array of two or more elements, the field is formed from its first two elements (and any additional elements are ignored):

  name = Bundler::URI.encode_www_form_component(ele[0], enc)
  value = Bundler::URI.encode_www_form_component(ele[1], enc)
  "#{name}=#{value}"

  Examples:

  Bundler::URI.encode_www_form([%w[foo bar], %w[baz bat bah]])
  # => "foo=bar&baz=bat"
  Bundler::URI.encode_www_form([['foo', 0], ['bar', :baz, 'bat']])
  # => "foo=0&bar=baz"

• If ele is an array of one element, the field is formed from ele[0]:

  Bundler::URI.encode_www_form_component(ele[0])

  Example:

  Bundler::URI.encode_www_form([['foo'], [:bar], [0]])
  # => "foo&bar&0"

• Otherwise the field is formed from ele:

  Bundler::URI.encode_www_form_component(ele)

  Example:

  Bundler::URI.encode_www_form(['foo', :bar, 0])
  # => "foo&bar&0"

The elements of an Array-like enum may be mixture:

Bundler::URI.encode_www_form([['foo', 0], ['bar', 1, 2], ['baz'], :bat])
# => "foo=0&bar=1&baz&bat"

When enum is Hash-like, each key+/+value pair is converted to one or more fields:

• If value is Array-convertible, each element ele in value is paired with key to form a field:

  name = Bundler::URI.encode_www_form_component(key, enc)
  value = Bundler::URI.encode_www_form_component(ele, enc)
  "#{name}=#{value}"

  Example:

  Bundler::URI.encode_www_form({foo: [:bar, 1], baz: [:bat, :bam, 2]})
  # => "foo=bar&foo=1&baz=bat&baz=bam&baz=2"

• Otherwise, key and value are paired to form a field:

  name = Bundler::URI.encode_www_form_component(key, enc)
  value = Bundler::URI.encode_www_form_component(value, enc)
  "#{name}=#{value}"

  Example:

  Bundler::URI.encode_www_form({foo: 0, bar: 1, baz: 2})
  # => "foo=0&bar=1&baz=2"

The elements of a Hash-like enum may be mixture:

Bundler::URI.encode_www_form({foo: [0, 1], bar: 2})
# => "foo=0&foo=1&bar=2"

Returns a URL-encoded string derived from the given string str.

The returned string:

• Preserves:

  • Characters '*', '.', '-', and '_'.

  • Character in ranges 'a'..'z', 'A'..'Z', and '0'..'9'.

  Example:

  Bundler::URI.encode_www_form_component('*.-_azAZ09')
  # => "*.-_azAZ09"

• Converts:

  • Character ' ' to character '+'.

  • Any other character to “percent notation”; the percent notation for character c is '%%%X' % c.ord.

  Example:

  Bundler::URI.encode_www_form_component('Here are some punctuation characters: ,;?:')
  # => "Herearesomepunctuationcharacters%3A+%2C%3B%3F%3A"

Encoding:

• If str has encoding Encoding::ASCII_8BIT, argument enc is ignored.

• Otherwise str is converted first to Encoding::UTF_8 (with suitable character replacements), and then to encoding enc.

In either case, the returned string has forced encoding Encoding::US_ASCII.

Synopsis

Bundler::URI::extract(str[, schemes][,&blk])

Args

str

String to extract URIs from.

schemes

Limit Bundler::URI matching to specific schemes.

Description

Extracts URIs from a string. If block given, iterates through all matched URIs. Returns nil if block given or array with matches.

Usage

require "bundler/vendor/uri/lib/uri"

Bundler::URI.extract("text here http://foo.example.org/bla and here mailto:test@example.com and here also.")
# => ["http://foo.example.com/bla", "mailto:test@example.com"]

Returns a new object constructed from the given scheme, arguments, and default:

• The new object is an instance of Bundler::URI.scheme_list[scheme.upcase].

• The object is initialized by calling the class initializer using scheme and arguments. See Bundler::URI::Generic.new.

Examples:

values = ['john.doe', 'www.example.com', '123', nil, '/forum/questions/', nil, 'tag=networking&order=newest', 'top']
Bundler::URI.for('https', *values)
# => #<Bundler::URI::HTTPS https://john.doe@www.example.com:123/forum/questions/?tag=networking&order=newest#top>
Bundler::URI.for('foo', *values, default: Bundler::URI::HTTP)
# => #<Bundler::URI::HTTP foo://john.doe@www.example.com:123/forum/questions/?tag=networking&order=newest#top>

return encoding or nil encoding.spec.whatwg.org/#concept-encoding-get

Merges the given URI strings str per RFC 2396.

Each string in str is converted to an RFC3986 Bundler::URI before being merged.

Examples:

Bundler::URI.join("http://example.com/","main.rbx")
# => #<Bundler::URI::HTTP http://example.com/main.rbx>

Bundler::URI.join('http://example.com', 'foo')
# => #<Bundler::URI::HTTP http://example.com/foo>

Bundler::URI.join('http://example.com', '/foo', '/bar')
# => #<Bundler::URI::HTTP http://example.com/bar>

Bundler::URI.join('http://example.com', '/foo', 'bar')
# => #<Bundler::URI::HTTP http://example.com/bar>

Bundler::URI.join('http://example.com', '/foo/', 'bar')
# => #<Bundler::URI::HTTP http://example.com/foo/bar>

Returns a new Bundler::URI object constructed from the given string uri:

Bundler::URI.parse('https://john.doe@www.example.com:123/forum/questions/?tag=networking&order=newest#top')
# => #<Bundler::URI::HTTPS https://john.doe@www.example.com:123/forum/questions/?tag=networking&order=newest#top>
Bundler::URI.parse('http://john.doe@www.example.com:123/forum/questions/?tag=networking&order=newest#top')
# => #<Bundler::URI::HTTP http://john.doe@www.example.com:123/forum/questions/?tag=networking&order=newest#top>

It’s recommended to first .escape string uri if it may contain invalid URI characters.

Synopsis

Bundler::URI::regexp([match_schemes])

Args

match_schemes

Array of schemes. If given, resulting regexp matches to URIs whose scheme is one of the match_schemes.

Description

Returns a Regexp object which matches to Bundler::URI-like strings. The Regexp object returned by this method includes arbitrary number of capture group (parentheses). Never rely on its number.

Usage

require 'bundler/vendor/uri/lib/uri'

# extract first Bundler::URI from html_string
html_string.slice(Bundler::URI.regexp)

# remove ftp URIs
html_string.sub(Bundler::URI.regexp(['ftp']), '')

# You should not rely on the number of parentheses
html_string.scan(Bundler::URI.regexp) do |*matches|
  p $&
end

Registers the given klass as the class to be instantiated when parsing a Bundler::URI with the given scheme:

Bundler::URI.register_scheme('MS_SEARCH', Bundler::URI::Generic) # => Bundler::URI::Generic
Bundler::URI.scheme_list['MS_SEARCH']                   # => Bundler::URI::Generic

Note that after calling String#upcase on scheme, it must be a valid constant name.

Returns a hash of the defined schemes:

Bundler::URI.scheme_list
# =>
{"MAILTO"=>Bundler::URI::MailTo,
 "LDAPS"=>Bundler::URI::LDAPS,
