Google云端硬盘上传PHP程序化登录

Question

I am developing a web API for a mobile app which needs to store files. Currently, the mobile clients send a request to the API with the file's data, and the file is stored directly on the server. However, I need to save space on the server and this is just a temporary solution.

What I would like to do is have the mobile client upload the file to the API, which then uploads that file to Google Drive. I have taken a look at the Google Drive API and I got it to upload a file from my home computer successfully, but in order to do so, I needed to sign in to my google account to authorize the upload. Here is the code:

<?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(' my client id ');
$client->setClientSecret(' my client secret ');
$client->setRedirectUri('https://www.hwassassin.net16.net/oauth2callback');
$client->setScopes(array('https://www.googleapis.com/auth/drive'));

$service = new Google_DriveService($client);

$authUrl = $client->createAuthUrl();

//Request authorization
print "Please visit:
$authUrl

";
print "Please enter the auth code:
";

$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);
?>

Since I need to upload the file from the backend, I would like to know if I can somehow programmatically log in to my Google Drive account from the server, without requiring the Client to take any action.

If this is not even possible, I would appreciate any alternative cloud storage API's that don't require the client to sign in to an account.

Any help would be greatly appreciated!

Solution is using application owned accounts using service accounts or regular accounts. Please follow the directions at https://developers.google.com/drive/web/service-accounts.
