Public Instance Methods

add_body_type_headers() click to toggle source

Adds the headers to the header array for the given request body we are working with

# File lib/http/request_stream.rb, line 36
def add_body_type_headers
  if @body.is_a? String and not @headers['Content-Length']
    @request_header << "Content-Length: #{@body.length}"
  elsif @body.is_a? Enumerable
    if encoding = @headers['Transfer-Encoding'] and not encoding == "chunked"
      raise ArgumentError, "invalid transfer encoding"
    else
      @request_header << "Transfer-Encoding: chunked"
    end
  end
end
add_headers() click to toggle source

Adds headers to the request header from the headers array

# File lib/http/request_stream.rb, line 22
def add_headers
  @headers.each do |field, value|

  end
end
join_headers() click to toggle source

Joins the headers specified in the request into a correctly formatted http request header string

# File lib/http/request_stream.rb, line 50
def join_headers

  # that ends the request header
  @request_header.join(CRLF) + (CRLF)*2
end

# File lib/http/request_stream.rb, line 64
def send_request_body
  if @body.is_a? String
    @socket << @body
  elsif @body.is_a? Enumerable
    @body.each do |chunk|
      @socket << chunk.bytesize.to_s(16) << CRLF
      @socket << chunk
    end

    @socket << "0" << CRLF * 2
  end
end
