So I'm trying to use Google Drive to get a list of file ID's and then use those file ID's to update the spreadsheets through the Google Sheets API.
I'm struggling to comprehend how exactly I should combine those authentications in Node.js in order to meet both authentications needs.
My goal is to create an Alexa app that updates spreadsheets and I currently have running and trying to expand off this app: https://github.com/acucciniello/alexa-open-doc
Because It's Alexa I'm assuming I can't store anything on the file system like I can locally so hence why I'm trying to use the token as hardcoded that I generated through my command line
Here's my attempt to combine Google Drive API + Sheets auth:
// authorize.js
var GoogleAuth = require('google-auth-library')
// Purpose: To set the credentials from the client_secret.json and checks if the token is valid
// param(in): credentials: Authentication information of user from client_secret.json
// param(in): token: The access token received from the lambda request and google
// param(in): callback: A function that handles the error or returns the authentication information
module.exports = function authorize (credentials, token, callback) {
var clientSecret = credentials.web.client_secret
var clientId = credentials.web.client_id
var redirectUrl = credentials.web.redirect_uris[0]
var auth = new GoogleAuth()
var oauth2Client = new auth.OAuth2(clientId, clientSecret, redirectUrl)
// Check if we have previously stored a token
oauth2Client.setCredentials({
access_token: token,
})
oauth2Client.credentials = "MY_COMMAND_LINE_TOKEN";
if (token === undefined) {
var undefinedToken = 'Token is undefined, please link the skill'
return callback(undefinedToken)
}
return callback(null, oauth2Client)
}
Here's my currently working Alexa + Google Drive Auth:
// authorize.js
var GoogleAuth = require('google-auth-library')
// Purpose: To set the credentials from the client_secret.json and checks if the token is valid
// param(in): credentials: Authentication information of user from client_secret.json
// param(in): token: The access token received from the lambda request and google
// param(in): callback: A function that handles the error or returns the authentication information
module.exports = function authorize (credentials, token, callback) {
var clientSecret = credentials.web.client_secret
var clientId = credentials.web.client_id
var redirectUrl = credentials.web.redirect_uris[0]
var auth = new GoogleAuth()
var oauth2Client = new auth.OAuth2(clientId, clientSecret, redirectUrl)
// Check if we have previously stored a token
oauth2Client.setCredentials({
access_token: token
})
if (token === undefined) {
var undefinedToken = 'Token is undefined, please link the skill'
return callback(undefinedToken)
}
return callback(null, oauth2Client)
}
And my Google Sheets Auth:
var fs = require('fs');
var readline = require('readline');
var google = require('googleapis');
var googleAuth = require('google-auth-library');
// If modifying these scopes, delete your previously saved credentials
// at ~/.credentials/sheets.googleapis.com-nodejs-quickstart.json
var SCOPES = ['https://www.googleapis.com/auth/spreadsheets'];
var TOKEN_DIR = (process.env.HOME || process.env.HOMEPATH ||
process.env.USERPROFILE) + '/.credentials/';
var TOKEN_PATH = TOKEN_DIR + 'sheets.googleapis.com-nodejs-quickstart.json';
// Load client secrets from a local file.
fs.readFile('client_secret.json', function processClientSecrets(err, content) {
if (err) {
console.log('Error loading client secret file: ' + err);
return;
}
// Authorize a client with the loaded credentials, then call the
// Google Sheets API.
authorize(JSON.parse(content), listMajors);
});
/**
* Create an OAuth2 client with the given credentials, and then execute the
* given callback function.
*
* @param {Object} credentials The authorization client credentials.
* @param {function} callback The callback to call with the authorized client.
*/
function authorize(credentials, callback) {
var clientSecret = credentials.installed.client_secret;
var clientId = credentials.installed.client_id;
var redirectUrl = credentials.installed.redirect_uris[0];
var auth = new googleAuth();
var oauth2Client = new auth.OAuth2(clientId, clientSecret, redirectUrl);
// Check if we have previously stored a token.
fs.readFile(TOKEN_PATH, function(err, token) {
if (err) {
getNewToken(oauth2Client, callback);
} else {
oauth2Client.credentials = JSON.parse(token);
callback(oauth2Client);
}
});
}
/**

* execute the given callback with the authorized OAuth2 client.
*
* @param {google.auth.OAuth2} oauth2Client The OAuth2 client to get token for.
* @param {getEventsCallback} callback The callback to call with the authorized
* client.
*/
function getNewToken(oauth2Client, callback) {
var authUrl = oauth2Client.generateAuthUrl({
access_type: 'offline',
scope: SCOPES
});
console.log('Authorize this app by visiting this url: ', authUrl);
var rl = readline.createInterface({
input: process.stdin,
output: process.stdout
});
rl.question('Enter the code from that page here: ', function(code) {
rl.close();
oauth2Client.getToken(code, function(err, token) {
if (err) {
console.log('Error while trying to retrieve access token', err);
return;
}
oauth2Client.credentials = token;
storeToken(token);
callback(oauth2Client);
});
});
}
/**
* Store token to disk be used in later program executions.
*
* @param {Object} token The token to store to disk.
*/
function storeToken(token) {
try {
fs.mkdirSync(TOKEN_DIR);
} catch (err) {
if (err.code != 'EEXIST') {
throw err;
}
}
fs.writeFile(TOKEN_PATH, JSON.stringify(token));
console.log('Token stored to ' + TOKEN_PATH);
}
