class HTTP::Request

Overview

An HTTP request.

It serves both to perform requests by an HTTP::Client and to represent requests received by an HTTP::Server.

A request always holds an IO as a body. When creating a request with a String or Bytes its body will be a IO::Memory wrapping these, and the Content-Length header will be set appropriately.

Defined in:

http/request.cr

Class Method Detail

def self.from_io(io, *, max_request_line_size : Int32 = HTTP::MAX_REQUEST_LINE_SIZE, max_headers_size : Int32 = HTTP::MAX_HEADERS_SIZE) : HTTP::Request | HTTP::Status | NilSource

Returns a HTTP::Request instance if successfully parsed, nil on EOF or HTTP::Status otherwise.

def body : IO?Source

def body=(body : String)Source

def body=(body : Bytes)Source

def body=(body : IO)Source

def body=(body : Nil)Source

def content_lengthSource

def content_length=(length : Int)Source

def cookies : HTTP::CookiesSource

Returns a convenience wrapper around querying and setting cookie related headers, see HTTP::Cookies.

def headers : HeadersSource

def headers=(headers : Headers)Source

def host_with_port : String?Source

Returns request host with port from headers.

DEPRECATED Use headers["Host"]? instead.

def hostname : String?Source

Extracts the hostname from Host header.

Returns nil if the Host header is missing.

If the Host header contains a port number, it is stripped off.

def if_match : Array(String)?Source

def if_none_match : Array(String)?Source

def ignore_body? : BoolSource

def keep_alive? : BoolSource

def local_address : Socket::Address?

The network address of the HTTP server.

HTTP::Server will try to fill this property, and its value will have a format like "IP:port", but this format is not guaranteed. Middlewares can overwrite this value.

This property is not used by HTTP::Client.

def local_address=(local_address : Socket::Address?)

The network address of the HTTP server.

HTTP::Server will try to fill this property, and its value will have a format like "IP:port", but this format is not guaranteed. Middlewares can overwrite this value.

This property is not used by HTTP::Client.

def method : StringSource

def method=(method : String)Source

def path : StringSource

Returns the request's path component.

def path=(path)Source

Sets request's path component.

def query : String?Source

Lazily parses and returns the request's query component.

def query=(value)Source

Sets request's query component.

def query_params : URI::ParamsSource

Returns a convenience wrapper around querying and setting query params, see URI::Params.

def remote_address : Socket::Address?

The network address that sent the request to an HTTP server.

HTTP::Server will try to fill this property, and its value will have a format like "IP:port", but this format is not guaranteed. Middlewares can overwrite this value.

Example:

class ForwarderHandler
  include HTTP::Handler

  def call(context)
    if ip = context.request.headers["X-Real-IP"]? # When using a reverse proxy that guarantees this field.
      context.request.remote_address = Socket::IPAddress.new(ip, 0)
    end
    call_next(context)
  end
end

server = HTTP::Server.new([ForwarderHandler.new, HTTP::LogHandler.new])

This property is not used by HTTP::Client.

def remote_address=(remote_address : Socket::Address?)

The network address that sent the request to an HTTP server.

HTTP::Server will try to fill this property, and its value will have a format like "IP:port", but this format is not guaranteed. Middlewares can overwrite this value.

Example:

class ForwarderHandler
  include HTTP::Handler

  def call(context)
    if ip = context.request.headers["X-Real-IP"]? # When using a reverse proxy that guarantees this field.
      context.request.remote_address = Socket::IPAddress.new(ip, 0)
    end
    call_next(context)
  end
end

server = HTTP::Server.new([ForwarderHandler.new, HTTP::LogHandler.new])

This property is not used by HTTP::Client.
