Download Images from google drive using API in node.js - google-drive-api

Question

Hi #iansedano, I wanted the code for achieving this. Below is my code :
// [START drive_quickstart]
const fs = require('fs');
const path = require('path');
const readline = require('readline');
const {google} = require('googleapis');
// If modifying these scopes, delete token.json.
const SCOPES = ['https://www.googleapis.com/auth/drive'];
// The file token.json stores the user's access and refresh tokens, and is
// created automatically when the authorization flow completes for the first
// time.
const TOKEN_PATH = 'token.json';
// Load client secrets from a local file.
let credPath = path.join(__dirname,'../../credentials.json');
fs.readFile(credPath, (err, content) => {
if (err) return console.log('Error loading client secret file:', err);
// Authorize a client with credentials, then call the Google Drive API.
authorize(JSON.parse(content), getFiles);
});
/**
* 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) {
const {client_secret, client_id, redirect_uris} = credentials.installed;
const oAuth2Client = new google.auth.OAuth2(
client_id, client_secret, redirect_uris[0]);
// Check if we have previously stored a token.
fs.readFile(TOKEN_PATH, (err, token) => {
if (err) return getAccessToken(oAuth2Client, callback);
oAuth2Client.setCredentials(JSON.parse(token));
});
}
/**
* Get and store new token after prompting for user authorization, and then
* 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 for the authorized client.
*/
function getAccessToken(oAuth2Client, callback) {
const authUrl = oAuth2Client.generateAuthUrl({
access_type: 'offline',
scope: SCOPES,
});
console.log('Authorize this app by visiting this url:', authUrl);
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout,
});
rl.question('Enter the code from that page here: ', (code) => {
rl.close();
oAuth2Client.getToken(code, (err, token) => {
if (err) return console.error('Error retrieving access token', err);
oAuth2Client.setCredentials(token);
// Store the token to disk for later program executions
fs.writeFile(TOKEN_PATH, JSON.stringify(token), (err) => {
if (err) return console.error(err);
console.log('Token stored to', TOKEN_PATH);
});
callback(oAuth2Client);
});
});
}
/**
* Lists the names and IDs of up to 10 files.
* #param {google.auth.OAuth2} auth An authorized OAuth2 client.
* #param fileId
* #param fileName
*/
function getFiles(auth) {
const drive = google.drive({version: 'v3', auth});
var filePath = path.join(__dirname, './../../images/photo.png');
//var filePath = path.join(__dirname,'./images/'+fileName+'.png');
var dest = fs.createWriteStream(filePath);
drive.files.get({fileId: '1hEKDGM4OoLQhhpSpqSxaMkrz0WmByQ0B', alt: 'media'}, {responseType: 'stream'},
function (err, res) {
res.data
.on('end', () => {
console.log('Done');
})
.on('error', err => {
console.log('Error', err);
})
.pipe(dest);
}
);
}
// [END drive_quickstart]
module.exports = {
SCOPES,
getFiles,
};
`Can any one help me download the file from Google drive using API in node.js ?
I have enabled the Google Drive API and created credentials.json from the oAuth2.
I need the code to download the image file using the file id. Please note that there is no web application involved here and I'm creating a Test script using codeceptjs to download the image from google drive and upload in another application.
