module Protocol::HTTP::URL

def self.encode(value, prefix = nil)

@parameter prefix [String] The prefix to use for keys.
@parameter value [Hash | Array | Nil] The value to encode.

Encodes a hash or array into a query string. This method is used to encode query parameters in a URL. For example, `{"a" => 1, "b" => 2}` is encoded as `a=1&b=2`. 
def self.encode(value, prefix = nil)
	case value
	when Array
		return value.map {|v|
			self.encode(v, "#{prefix}[]")
		}.join("&")
	when Hash
		return value.map {|k, v|
			self.encode(v, prefix ? "#{prefix}[#{escape(k.to_s)}]" : escape(k.to_s))
		}.reject(&:empty?).join("&")
	when nil
		return prefix
	else
		raise ArgumentError, "value must be a Hash" if prefix.nil?
		
		return "#{prefix}=#{escape(value.to_s)}"
	end
