Uploading files to Google Drive - php

Question

I am trying to upload files from my PHP-based website to Google Drive. I searched, got google-api-php-client library. In documentation an example is given but that can be run on php shell (Command line). I tried to run that example in browser, I got error of curl extention, and fixed that.
Now I am getting error related to authenticating code to allow access. I do not need authentication at all in my project, but for the time being I can try with it.
I have the following code in www.mydomain.com/drive/index.php file:
<?php
require_once 'google-api-php-client/src/Google_Client.php';
require_once 'google-api-php-client/src/contrib/Google_DriveService.php';
$client = new Google_Client();
// Get your credentials from the APIs Console
$client->setClientId('MY-CLIENT-ID');
$client->setClientSecret('MY-CLIENT-SECRET');
$client->setRedirectUri('http://www.MY-DOMAIN.com/drive/auth.php');
//AUTH.PHP should have code to authenticate code and return back another code.
$client->setScopes(array('https://www.googleapis.com/auth/drive'));
$service = new Google_DriveService($client);
//**********************authentication process for SHELL
//I want this authentication process to remove at all or convert to web based authentication
$authUrl = $client->createAuthUrl();
//Request authorization
print "Please visit:\n$authUrl\n\n";
print "Please enter the auth code:\n";
$authCode = trim(fgets(STDIN));
// Exchange authorization code for access token
$accessToken = $client->authenticate($authCode);
$client->setAccessToken($accessToken);
//************************************************************
//Insert a file
$file = new Google_DriveFile();
$file->setTitle('My document');
$file->setDescription('A test document');
$file->setMimeType('text/plain');
$data = file_get_contents('document.txt');
$createdFile = $service->files->insert($file, array(
'data' => $data,
'mimeType' => 'text/plain',
));
print_r($createdFile);
?>
Can I upload file without authentication need for each upload? If yes then how? If no then how to authenticate?

Answer 1

You can't use the exact same example that is meant for console development into web development.
You should do some changes, I'll give you mine as an example :
<?php
require_once 'googleapi/Google_Client.php';
require_once 'googleapi/contrib/Google_DriveService.php';
session_start();
$client = new Google_Client();
// Get your credentials from the APIs Console
$client->setApplicationName('Google+ PHP Starter Application');
$client->setClientId('ID');
$client->setClientSecret('Secret');
$client->setRedirectUri('Redirect');
//Voy a la dirección de la creación del permiso
$authUrl = $client->createAuthUrl();
print "<a href='$authUrl'>Connect Me!</a>";
//Regreso de la dirección con el código con el que puedo autenticarme
if (isset($_GET['code'])) {
$accessToken = $client->authenticate($_GET['code']);
file_put_contents('conf.json', $accessToken);
$client->setAccessToken($accessToken);
$redirect = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
header('Location: ' . filter_var($redirect, FILTER_SANITIZE_URL));
}
$client->setAccessToken(file_get_contents('conf.json'));
if ($client->getAccessToken()) {
//Significa que tengo derecho a manipular el servicio como quiera
// Elijo el servicio que quiero usar
$service = new Google_DriveService($client);
$file = new Google_DriveFile();
/*$file->setTitle('My document');
$file->setDescription('A test document');
$file->setMimeType('text/plain');
$data = file_get_contents('document.txt');
$createdFile = $service->files->insert($file, array(
'data' => $data,
'mimeType' => 'text/plain',
));
print_r($createdFile);
print "test";*/
}
?>
