`class Request`

A Rack-compatible HTTP request wrapper. This class provides a bridge between Rack's environment hash and Protocol::HTTP::Request. It handles conversion of Rack environment variables to HTTP request properties.

Definitions

`def self.[](env)`

Get or create a Request instance for the given Rack environment. The request is cached in the environment to avoid creating multiple instances.

Signature

parameter　env　Hash: The Rack environment hash.
returns　Request: A Request instance for the environment.

Implementation

def self.[](env)
	env["protocol.http.request"] ||= new(env)
end

`def initialize(env)`

Initialize a new Request instance from a Rack environment.

Signature

parameter　env　Hash: The Rack environment hash.

Implementation

def initialize(env)
	@env = env

	super(
		@env["rack.url_scheme"],
		@env["HTTP_HOST"],
		@env["REQUEST_METHOD"],
		@env["PATH_INFO"],
		@env["SERVER_PROTOCOL"],
		self.class.headers(@env),
		Body::InputWrapper.new(@env["rack.input"]),
		self.class.protocol(@env)
	)
end

`def self.protocol(env)`

Extract the protocol list from the Rack environment. Checks both rack.protocol and HTTP_UPGRADE headers.

Signature

parameter　env　Hash: The Rack environment hash.
returns　Array(String) | Nil: The list of protocols or nil if none specified.

Implementation

def self.protocol(env)
	if protocols = env["rack.protocol"]
		return Array(protocols)
	elsif protocols = env[CGI::HTTP_UPGRADE]
		return protocols.split(/\s*,\s*/)
	end
end

`def self.headers(env)`

Extract HTTP headers from the Rack environment. Converts Rack's HTTP_* environment variables to proper HTTP headers.

Signature

parameter　env　Hash: The Rack environment hash.
returns　Protocol::HTTP::Headers: The extracted HTTP headers.

Implementation

def self.headers(env)
	headers = ::Protocol::HTTP::Headers.new
	env.each do |key, value|
		if key.start_with?("HTTP_")
			next if key == "HTTP_HOST"
			headers[key[5..-1].gsub("_", "-").downcase] = value
		end
	end

	return headers
end
