module Bundler::URI

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"}

Decodes given str of URL-encoded form data.

This decodes + to SP.

def self.decode_www_form_component(str, enc=Encoding::UTF_8)

end

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"

          str << '='
          str << encode_www_form_component(w, enc)
        end

      str << '='
      str << encode_www_form_component(v, enc)
    end
  end.join('&')
end

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.
