Firebase调度功能在部署时出错

Question

我指的是 Cloud 功能的 Firebase 文档来安排功能。但是尝试部署时出现以下错误。

Error: Error occurred while parsing your function triggers.

token-refresh/functions/index.js:5
export scheduledFunction = functions.pubsub.schedule('5 23 * * *').onRun((context) => {
^^^^^^

SyntaxError: Unexpected token export

我只是尝试部署文档中的确切功能，但它给出了错误。

我尝试部署的代码，

const functions = require('firebase-functions');

export scheduledFunction = functions.pubsub.schedule('5 23 * * *').onRun((context) => {
    console.log('This will be run at 23.05 UTC');
});

我的版本：

Firebase/firebase-tools：7.0.0

节点：11.11.0

npm：6.7.0

文档 https://firebase.google.com/docs/functions/schedule-functions

Answer 1

以下应该有效：

const functions = require('firebase-functions');

exports.scheduledFunction = functions.pubsub.schedule('5 23 * * *').onRun((context) => {
    console.log('This will be run at 23.05 UTC');
});
