Class Method Details

.decode_www_form(str, enc = Encoding::UTF_8, separator: '&', use__charset_: false, isindex: false) ⇒ Object

Decodes URL-encoded form data from given str.

This decodes application/x-www-form-urlencoded data and returns an array of key-value arrays.

This refers url.spec.whatwg.org/#concept-urlencoded-parser, so this supports only &-separator, and doesn’t support ;-separator.

ary = Bundler::URI.decode_www_form("a=1&a=2&b=3")
ary                   #=> [['a', '1'], ['a', '2'], ['b', '3']]
ary.assoc('a').last   #=> '1'
ary.assoc('b').last   #=> '3'
ary.rassoc('a').last  #=> '2'
Hash[ary]             #=> {"a"=>"2", "b"=>"3"}

See Bundler::URI.decode_www_form_component, Bundler::URI.encode_www_form.

Raises:

  • (ArgumentError)

.decode_www_form_component(str, enc = Encoding::UTF_8) ⇒ Object

Decodes given str of URL-encoded form data.

This decodes + to SP.

Raises:

  str.b.gsub(/\+|%\h\h/, TBLDECWWWCOMP_).force_encoding(enc)
end

.encode_www_form(enum, enc = nil) ⇒ Object

Generates URL-encoded form data from given enum.

This generates application/x-www-form-urlencoded data defined in HTML5 from given an Enumerable object.

This internally uses Bundler::URI.encode_www_form_component(str).

This method doesn’t convert the encoding of given items, so convert them before calling this method if you want to send data as other than original encoding or mixed encoding data. (Strings which are encoded in an HTML5 ASCII incompatible encoding are converted to UTF-8.)

This method doesn’t handle files. When you send a file, use multipart/form-data.

This refers url.spec.whatwg.org/#concept-urlencoded-serializer

Bundler::URI.encode_www_form([["q", "ruby"], ["lang", "en"]])
#=> "q=ruby&lang=en"
Bundler::URI.encode_www_form("q" => "ruby", "lang" => "en")
#=> "q=ruby&lang=en"
Bundler::URI.encode_www_form("q" => ["ruby", "perl"], "lang" => "en")
#=> "q=ruby&q=perl&lang=en"
Bundler::URI.encode_www_form([["q", "ruby"], ["q", "perl"], ["lang", "en"]])
#=> "q=ruby&q=perl&lang=en"

.encode_www_form_component(str, enc = nil) ⇒ Object

Encodes given str to URL-encoded form data.

This method doesn’t convert *, -, ., 0-9, A-Z, _, a-z, but does convert SP (ASCII space) to + and converts others to %XX.

If enc is given, convert str to the encoding before percent encoding.

This is an implementation of www.w3.org/TR/2013/CR-html5-20130806/forms.html#url-encoded-form-data.

See Bundler::URI.decode_www_form_component, Bundler::URI.encode_www_form.

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.

.parse(uri) ⇒ Object

Synopsis

Bundler::URI::parse(uri_str)

Args

uri_str

String with Bundler::URI.

Description

Creates one of the Bundler::URI’s subclasses instance from the string.

Raises

Bundler::URI::InvalidURIError

Raised if Bundler::URI given is not a correct one.

Usage

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

uri = Bundler::URI.parse("http://www.ruby-lang.org/")
# => #<Bundler::URI::HTTP http://www.ruby-lang.org/>
uri.scheme
# => "http"
uri.host
# => "www.ruby-lang.org"

It’s recommended to first ::escape the provided uri_str if there are any invalid Bundler::URI characters.

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 it’s number.

Usage

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

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 $&
