将文件上传到Google云端硬盘

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";*/
}
?>
