适用于Firebase的Cloud Functions:functions.pubsub.topic(' testTopic').onPublish未调用

问题描述

我已经从云功能的官方文档中复制了此代码段:

I've copied this code snippet from the official documentation of cloud functions:

exports.helloPubSub = functions.pubsub.topic('testTopic').onPublish(event => {
    return console.log("test topic event data", event.data) 
})

该主题存在，该功能已成功部署；如果我向其发送消息，则消息到达了设备，但是没有调用此函数.

The topic exists, the function is deployed successfully; if I send a message to it, the message arrives to the devices, BUT this function does not get called.

有人帮忙吗?

推荐答案

Firebase(Google)云消息传递和Google Cloud Pub/Sub是不同的消息传递系统，例如在此处解释:

Firebase (Google) Cloud Messaging and Google Cloud Pub/Sub are different messaging systems, as explained here:

尽管他们共享主题的概念，但是发送到FCM主题的消息不会触发 Pub/Sub Cloud Function .

Although they share the concept of topics, a message sent to an FCM topic will not trigger a Pub/Sub Cloud Function.
