 */
exports.gcf_post = (req, res) => {
  var str_out = ""
  str_out += "これはテストです。\n"
  str_out += "Good Evening\n"
  str_out += "今晩は\n"
  str_out += "Mar/11/2018 PM 18:02\n"
  const user = req.body['user']
  const password = req.body['password']
  str_out += "user = " + user + "\n"
  str_out += "password = " + password + "\n"
  res.send(str_out)
}
