Prepares the basic functionality for responses that have a body (directly following the status line).

Every class that includes this can use strings or objects responding to readline to retrieve the body.

Instance Method Details

#body ⇒ Object

Returns the body attribute.

If a block is given, the results will be sent to body= before returning the attribute.

def body
  self.body = yield if block_given?
  @body
end

#body=(body) ⇒ Object

Sets the body attribute.

The parameter body can be a string or an object responding to readline. Reading will be halted at a line with a single dot followed by <CRLF> or <LF>, or when an EOFError occurs. The result will be stored in the internal attribute @raw. Subsequently, parse_body will be called.

def body=(body)
  if body.respond_to? :readline
    begin
      @raw = ''
      loop do
        line = body.readline
        @raw << line
        break if line =~/\A\.\r?\n\z/m
      end
    rescue EOFError => e
    end
  else
    @raw = body
  end
  parse_body
end

#parse_body ⇒ Object

Is called from body= and should be used to set the @body attribute transforming the contents of the @raw attribute.
