我找到了这个并且非常适合我。

BOUNDARY = "AaB03x"

def encode_multipartformdata(parameters = {})
  ret = String.new
  parameters.each do |key, value|
    unless value.empty?
      ret << "\r\n--" << BOUNDARY << "\r\n"
      ret << "Content-Disposition: form-data; name=\"#{key}\"\r\n\r\n"
      ret << value
    end
  end
  ret << "\r\n--" << BOUNDARY << "--\r\n"
end
