在模拟器中以编程方式调用 gcloud 后台函数

Question

我已经在模拟器中部署了 gcloud 后台功能 (pubsub)。

它正在从命令行成功调用

functions call helloPubSub --data='{"message":"Hello World"}'

如何从本地服务器代码调用 gcloud 本地函数？

= = =

下面是我在服务器端发布到主题的代码

pubsub
  .topic(topicName)
  .publisher()
  .publish(dataBuffer)
  .then(results => {
    const messageId = results[0];
    console.log(`Message ${messageId} published.`);
    res.status(200)
    res.send({hello:'world'})

  })
  .catch(err => {
    console.error('ERROR:', err);
    res.status(200)
    res.send({err:err})
  });    

我收到以下错误消息

{"err":{"code":7,"metadata":{"_internal_repr":{}},"note":"Exception occurred in retry method that was not classified as transient"}}

在 official docs 中指出：

Note: Functions deployed in the Emulator with non-HTTP triggers like Cloud Storage or Cloud Pub/Sub will not be invoked by these services. The Emulator is intended as a development environment only, so you would need to call these functions manually to have them invoked.

因此，如果您使用 Cloud Pub/Sub 触发器在本地部署了一个函数，调用它的唯一方法是使用命令行命令：

functions call [your-function]
