Question

我正在尝试验证用户以访问用户Gsuite中的各种范围。我可以在本地运行代码，但似乎无法将其接受为云函数。

我尝试使用Firebase和gcloud进行部署。我已经检查了陪同人员的设置。

此代码来自https://github.com/googleapis/google-api-nodejs-client/blob/master/README.md#oauth2-client

'use strict';

const fs = require('fs');
const path = require('path');
const http = require('http');
const url = require('url');
const opn = require('open');
const destroyer = require('server-destroy');

const {google} = require('googleapis');

/**
 * To use OAuth2 authentication, we need access to a a CLIENT_ID, CLIENT_SECRET, AND REDIRECT_URI.  To get these credentials for your application, visit https://console.cloud.google.com/apis/credentials.
 */
const keyPath = path.join(__dirname, 'credentials.json');
let keys = {redirect_uris: ['']};
if (fs.existsSync(keyPath)) {
  keys = require(keyPath).web;
}

/**
 * Create a new OAuth2 client with the configured keys.
 */
const oauth2Client = new google.auth.OAuth2(
  keys.client_id,
  keys.client_secret,
  `http://localhost:3000/oauth2callback`
);

/**
 * This is one of the many ways you can configure googleapis to use authentication credentials.  In this method, we're setting a global reference for all APIs.  Any other API you use here, like google.drive('v3'), will now use this auth client. You can also override the auth client at the service and method call levels.
 */
google.options({auth: oauth2Client});
const scopes = ['https://www.googleapis.com/auth/documents'];
/**
 * Open an http server to accept the oauth callback. In this simple example, the only request to our webserver is to /callback?code=<code>
 */
async function authenticate(){
    // grab the url that will be used for authorization
    const authorizeUrl = oauth2Client.generateAuthUrl({
      access_type: 'offline',
      scope: scopes
    });

    const server = http.createServer(async (req, res) => {
        try {
          if (req.url.indexOf('/oauth2callback') > -1) {
            const qs = new url.URL(req.url, 'http://localhost:3000').searchParams;
            res.end('Authentication successful! Please return to the console.');
            server.destroy();
            const {tokens} = await oauth2Client.getToken(qs.get('code'));
            oauth2Client.credentials = tokens; // eslint-disable-line require-atomic-updates
            resolve(oauth2Client);
          }
        } catch (e) {
          reject(e);
        }
      })

      .listen(3000, () => {
        // open the browser to the authorize url to start the workflow
        opn(authorizeUrl, {wait: false}).then(cp => cp.unref())
        .catch(
            error => { 
            console.log(error);
        });
      });

    destroyer(server)
     .then(client => runSample(client)).catch(
         error => { 
         console.log(error);
       });
};
module.exports.authenticate=authenticate;

async function runSample(client) {
  // retrieve user profile
  console.log(client);
  const docs = google.docs({
    version: 'v1',
    auth: client
  });
  const createResponse = await docs.documents.create({
    requestBody: {
      title: 'Your new document!',
    },
  });
}

我希望它可以作为云功能加载到Firebase或gcloud。然而： Firebase返回“部署完成”，但从不显示在功能中。 gcloud返回“ SyntaxError：意外的令牌函数”，并在“异步函数authenticate（）{”

中指出该词

我是node.js的新手，可能会错过其他人真正显而易见的东西。

您将永远无法获得用户凭证（客户端ID /客户端密钥）在Cloud Functions中（意味着认证和创建凭证）。 OAuth需要Web浏览器和人员。云中都不存在功能。请改用服务帐户。 –约翰·汉利
