如何从Firebase Cloud功能在Google Pub / Sub中发布消息？ [英] How to publish message in Google Pub/Sub from Firebase Cloud Function?

问题描述

我编写了一个接收http请求并发送电子邮件的函数。但我想发送消息pubsub，但在文档中的示例只显示触发的pubsub请求，并且没有主机，端口，id，代理的passwd等信息。我想收到一个http请求并向移动设备发送一条发布消息，我认为这是mqtt。

I write a function that receive a http request and send a e-mail. But I wants send a message pubsub, but in the documentation the examples showing only triggered pubsub requests and no have information like host, port, id, passwd of broker. I wants receive a http request and send a pub message, I think that is mqtt, to a mobile device.

exports.weeklyEmail = functions.https.onRequest((req,res) => {
const email = '****@gmail.com'

console.log('Sending e-mail')

const mailOptions = {
    to: email,
    from: '****@alunos.utfpr.edu.br',
    subject: 'Teste',
    text: 'Conteudo do email '
}   

mailTransport.sendMail(mailOptions).then(
    () => {         
        res.send('Email sent')
    }
).catch(error => {
    res.send(error)
})
})

推荐答案

据我所知，您希望从Firebase云功能实施中向Pub / Sub发送消息。

As I understand, you wish to send a message to Pub/Sub from your Firebase Cloud Functions implementation.

您可以轻松使用 Node.js Pub / Sub客户端库，已定义的功能，例如发布。

You can easily use the Node.js Pub/Sub client library, with already defined functionalities, like publish.

或者，如果您愿意，可以建立自己的客户，直接致电 Google Cloud Pub / Sub的REST API 。如果它更适合您的需要，还有 RPC参考。

Or, if you prefer, you can build your own client, directly calling the REST API for Google Cloud Pub/Sub. There's also a RPC reference if it suits your needs better.

您不需要

信息像主机，端口，id，passwd of broker

information like host, port, id, passwd of broker

作为上述客户端，或者你的REST API请求需要身份验证
。

as the mentioned client, or your REST API requests will require authentication .
