axios async await Cloud Function 在 axios 完成 post 请求之前返回

Question

I have a react app, with a message page. The message page allows the user to submit a message. The submission process sends the message info to a Cloud Function deployed on Firebase Functions (Google Cloud). The function responds with an object like this:

{
    success: true,
    message: 'Your message has been sent.'
}

This is the cloud function:

 const functions = require('firebase-functions') const admin = require('firebase-admin') admin.initializeApp() const fs = admin.firestore() const axios = require('axios') exports.sendMessage = functions.https.onCall(async (input) => { try { let outcome = await axios({ method: 'post', url: 'https://recaptcha.google.com/recaptcha/api/siteverify', params: { secret: --redacted--, response: input.recaptchaToken } }) outcome.data.success && fs.collection("messages").add({ timestamp: admin.firestore.FieldValue.serverTimestamp(), name: input.name, email: input.email, message: input.message }) return outcome.data.success ? { success: true, message: 'Your message has been sent.' } : { success: false, message: `Your message failed. You're a robot.` } } catch (error) { console.error('Cloud Function error:', error) return { success: false, message: 'Your message failed. Try again later.' } } })

However, it isn't working as intended. The message successfully writes to Firestore, however the object I receive back is success: false, message: 'Your message failed. Try again later.'' success: false, message: 'Your message failed. Try again later.''

The error I get from logging on Cloud Function is this:

ReferenceError: data is not defined
at exports.testSendMessage.functions.https.onCall

... which implies that the function isn't waiting for axios to resolve with a response (even though it does later), and is instead continuing on with the function, resulting in the error.

What is going on?

Answer 1

ReferenceError: data is not defined is telling you that outcome.data is undefined. You should do more logging to determine why outcome is something other than what you expect.
