gcloud で Google Cloud Functions を使う

次の Cloud Function を gcloud から使う方法です。

test-function-uchida-apr04

/**
 * Responds to any HTTP request.
 *
 * @param {!express:Request} req HTTP request context.
 * @param {!express:Response} res HTTP response context.
 */
exports.helloWorld = (req, res) => {
  let message = req.query.message || req.body.message || 'Hello World! Apr/04/2022 PM 16:12';
  res.status(200).send(message);
};

Region は asia-northeast1
Project は　project-apr0401
とします。

$ gcloud functions list
