Google Drive PHP API - Simple File Upload

Question

I am trying to write a small script to upload a local file to Google Drive, using Google Drive PHP API. The documentation is very poor maintained, but so far I am pretty sur

Answer 1

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;

References in:

• https://developers.google.com/drive/api/v3/quickstart/php
• https://developers.google.com/drive/api/v3/reference/files/create
• https://developers.google.com/drive/api/v3/manage-uploads

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

<?php

require __DIR__ . '/vendor/autoload.php';

function getClient()

    $client->setScopes(Google_Service_Drive::DRIVE);
    $client->setAuthConfig('credentials.json');
    $client->setAccessType('offline');
    $client->setPrompt('select_account consent');


    // Load previously authorized token from a file, if it exists.
    // 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.
    $tokenPath = 'token.json';
    if (file_exists($tokenPath)) {
        $accessToken = json_decode(file_get_contents($tokenPath), true);
        $client->setAccessToken($accessToken);
    }

    if ($client->isAccessTokenExpired()) {

Use this

<?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 console
    $client->setClientId('YOUR_CLIENT_ID');
    $client->setClientSecret('YOUR_CLIENT_SECRET');
    $client->setRedirectUri('urn:ietf:wg:oauth:2.0:oob');
    $client->setScopes(array('https://www.googleapis.com/auth/drive'));

    $service = new Google_DriveService($client);

    $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();
    $localfile = 'a.jpg';
    $title = basename($localfile);
    $file->setTitle($title);
    $file->setDescription('My File');
    $file->setMimeType('image/jpeg');

    $data = file_get_contents($localfile);

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

    print_r($createdFile);
    ?>

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();
}
