Google Drive PHP API - Simple File Upload

I was able to run a PHP added in CRON. He asks for the verification code only the first time and then everything works. I've been running CRON for over 16h and everything is working perfectly.

Well, considering you've done the steps:

1. Create a Project on Google Cloud Platform;
2. In Credentials, you already have the OAuth 2.0 Client ID;
3. Downloaded credentials and renamed credentials.json;
4. Used composer to download Google Drive libraries;

This code here is the "working" result of an upload to Google Drive in a specific subfolder. I hope it helps.

Use this

<?php

    require_once 'google-api-php-client/src/contrib/Google_DriveService.php';

    $client = new Google_Client();

    $authCode = trim(fgets(STDIN));

    // Exchange authorization code for access token

Use this code to authenticate and upload a test file. You need to set <YOUR_REGISTERED_REDIRECT_URI> (and also in console) to this document itself to authenticate.

require_once 'Google/Client.php';
require_once 'Google/Service/Drive.php';

$client = new Google_Client();
// Get your credentials from the console
$client->setClientId('<YOUR_CLIENT_ID>');
$client->setClientSecret('<YOUR_CLIENT_SECRET>');
$client->setRedirectUri('<YOUR_REGISTERED_REDIRECT_URI>');
$client->setScopes(array('https://www.googleapis.com/auth/drive.file'));

session_start();

if (isset($_GET['code']) || (isset($_SESSION['access_token']) && $_SESSION['access_token'])) {
    if (isset($_GET['code'])) {
        $client->authenticate($_GET['code']);
        $_SESSION['access_token'] = $client->getAccessToken();
    } else
        $client->setAccessToken($_SESSION['access_token']);

    $service = new Google_Service_Drive($client);

    //Insert a file
    $file = new Google_Service_Drive_DriveFile();
    $file->setName(uniqid().'.jpg');
    $file->setDescription('A test document');
    $file->setMimeType('image/jpeg');

    $data = file_get_contents('a.jpg');

    $createdFile = $service->files->create($file, array(
          'data' => $data,
          'mimeType' => 'image/jpeg',
          'uploadType' => 'multipart'
        ));

    print_r($createdFile);

} else {
    $authUrl = $client->createAuthUrl();
    header('Location: ' . $authUrl);
    exit();
}
