如何上传到谷歌驱动器与服务帐户和php

Question

下面你可以看到我的代码，它上传文件到我的谷歌驱动器。现在我正试图使用服务帐户，让人们上传文件到我的谷歌驱动器没有他们的谷歌帐户(访问者将提交html表单与他们的文件和我的应用程序将该文件上传到我的驱动器)。但我被它困住了。甚至连一个可行的例子都找不到。什么好主意吗?

$client = new GoogleClient();
$client->setAuthConfig('credentials.json');
$client->addScope(GoogleServiceDrive::DRIVE);
$redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
$client->setRedirectUri($redirect_uri);
if (isset($_GET['code'])) {
$token = $client->fetchAccessTokenWithAuthCode($_GET['code']);
$client->setAccessToken($token);
// store in the session also
$_SESSION['upload_token'] = $token;
// redirect back to the example
header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}
if (!empty($_SESSION['upload_token'])) {
$client->setAccessToken($_SESSION['upload_token']);
if ($client->isAccessTokenExpired()) {
unset($_SESSION['upload_token']);
}
} else {
$authUrl = $client->createAuthUrl();
}
echo $client->getAccessToken();
if ($_SERVER['REQUEST_METHOD'] == 'GET' && $client->getAccessToken()) {
// We'll setup an empty 1MB file to upload.
DEFINE("TESTFILE", 'test.jpg');
if (!file_exists(TESTFILE)) {
$fh = fopen(TESTFILE, 'w');
fseek($fh, 1024 * 1024);
fwrite($fh, "!", 1);
fclose($fh);
}
// This is uploading a file directly, with no metadata associated.
$file = new GoogleServiceDriveDriveFile();
$service = new Google_Service_Drive($client);
$file->setName("Hello World!");
$result = $service->files->create(
$file,
[
'data' => file_get_contents(TESTFILE),
'mimeType' => 'application/octet-stream',
'uploadType' => 'media'
]
);
$permissionService = new Google_Service_Drive_Permission();
$permissionService->role = "reader";
$permissionService->type = "anyone"; // anyone with the link can view the file
$service->permissions->create($result->id, $permissionService);

以下代码将向您展示如何设置服务帐户授权。

请记住，文件将上传到服务帐户驱动器帐户。如果你想上传到你的个人硬盘账户。您需要与服务帐户共享驱动器帐户上的目录。你可以像对待其他用户一样通过web应用程序，使用服务帐户电子邮件地址。它的属性看起来像一个电子邮件。

您应该能够删除您现在拥有的授权，然后使用它。但是，您需要将上传元数据中的父目录设置为您希望将填充上载到的目录的父目录。

// Load the Google API PHP Client Library.
require_once __DIR__ . '/vendor/autoload.php';
// Use the developers console and download your service account
// credentials in JSON format. Place the file in this directory or
// change the key file location if necessary.
putenv('GOOGLE_APPLICATION_CREDENTIALS='.__DIR__.'/service-account.json');

/**
* Gets the Google client refreshing auth if needed.
* Documentation: https://developers.google.com/identity/protocols/OAuth2ServiceAccount
* Initializes a client object.
* @return A google client object.
*/
function getGoogleClient() {
return getServiceAccountClient();
}
/**
* Builds the Google client object.
* Documentation: https://developers.google.com/api-client-library/php/auth/service-accounts
* Scopes will need to be changed depending upon the API's being accessed. 
* array(Google_Service_Analytics::DRIVE)
* List of Google Scopes: https://developers.google.com/identity/protocols/googlescopes
* @return A google client object.
*/
function getServiceAccountClient() {
try {   
// Create and configure a new client object.        
$client = new Google_Client();
$client->useApplicationDefaultCredentials();
$client->addScope(array(Google_Service_Analytics::DRIVE));
return $client;
} catch (Exception $e) {
print "An error occurred: " . $e->getMessage();
}
}

这样做会得到相同的服务对象。

$service = new Google_Service_Drive(getGoogleClient());
