使用javascript承诺从firebase云函数读取google表单

几个小时以来,我一直在努力解决一个涉及firebase云功能和google sheets api的问题。我只是想在一个 POST 请求我的云功能。

下面的代码,我使用函数从电子表格中读取 readCells 工作正常:

const {google} = require('googleapis');
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
var db = admin.firestore();

// magic function (?)
function readCells(auth, ssheetId) {
    const sheets = google.sheets({version: 'v4', auth});
    return new Promise((resolve, reject) => {
        sheets.spreadsheets.values.get({spreadsheetId:ssheetId,
                                        range:'MySheet!A1:A2'},
                                        (err, result) => {
            if (err) {
                reject(err);
            }
            resolve(result);
        });
    });
}

exports.test = functions.https.onRequest((request, response) => {
    // read auth token & spreadsheet ID from Cloud Firestore        
    let tokenPromise = db.doc('config/token').get();
    let spreadsheetPromise = db.doc('config/spreadsheet').get();

    // read from spreadsheet
    return Promise.all([tokenPromise, spreadsheetPromise]).then(results => {
        const token = results[0].data();
        const ssheetId = results[1].data().id;
        const oAuth2Client = new google.auth.OAuth2(token.client_id, token.client_secret, "");
        oAuth2Client.setCredentials(token);
        return readCells(oAuth2Client, ssheetId);
    })
    .then(result => {
        console.log(result.data.values);
        return response.status(200).end();
    })
    .catch(err => {
        console.error(err);
        return response.status(500).end();
    });
});

然后我摆脱 小精灵 做任何事 HTTPS 云函数 test :

exports.test = functions.https.onRequest((request, response) => {
    // read auth token & spreadsheet ID from Cloud Firestore
    let tokenPromise = db.doc('config/token').get();
    let spreadsheetPromise = db.doc('config/spreadsheet').get();

    // read from spreadsheet
    return Promise.all([tokenPromise, spreadsheetPromise]).then(results => {
        const token = results[0].data();
        const ssheetId = results[1].data().id;
        const oAuth2Client = new google.auth.OAuth2(token.client_id, token.client_secret, "");
        oAuth2Client.setCredentials(token);
        const sheets = google.sheets({version: 'v4', oAuth2Client});
        return new Promise((resolve, reject) => {
            sheets.spreadsheets.values.get({spreadsheetId:ssheetId,
                                            range:'MySheet!A1:A2'},
                                            (err, result) => {
                if (err) {
                    reject(err);
                }
                resolve(result);
            });
        });
    })
    .then(result => {
        console.log(result.data.values);
        return response.status(200).end();
    })
    .catch(err => {
        console.error(err);
        return response.status(500).end();
    });
});

但我得到了以下错误:

error: { Error: The request is missing a valid API key.

    at settle (/<path_to_functions>/node_modules/axios/lib/core/settle.js:18:12)

    at process._tickCallback (internal/process/next_tick.js:180:9)
    ...
    more stuff
    ...

还有:

error: (node:3308) UnhandledPromiseRejectionWarning: 
Unhandled promise rejection. This error originated either by throwing
inside of an async function without a catch block,
or by rejecting a promise which was not handled with .catch(). (rejection id: 2)
(node:3308) [DEP0018] DeprecationWarning: Unhandled promise rejections
are deprecated. In the future, promise rejections that are not handled
will terminate the Node.js process with a non-zero exit code.

我完全不理解这种行为。我只在不使用函数的情况下做同样的事情。我对javascript或node.js不是很有经验;如果有任何帮助,我将不胜感激。
