Google Drive API can't set permissions with reusable upload - google-drive-api

Question

When I did a basic file upload & set the permission like so, it worked great:
$file = $service->files->create($fileMetadata, array(
'data' => $content,
'mimeType' => $mimeType,
'uploadType' => 'multipart',
'fields' => 'id'));
$permissions = new Google_Service_Drive_Permission(array(
"role" => "reader",
"type" => "anyone",
));
$setPermission = $service->permissions->create($file->id, $permissions);
But when I upload a large file that's split into chunks & use the resumable uploadType, the permissions aren't set on the file & I don't get any errors:
$service = new Google_Service_Drive($client);
$file = new Google_Service_Drive_DriveFile();
$file->title = $fileName;
$file->name = $fileName;
$chunkSizeBytes = 1 * 1024 * 1024;
$mimeType = mime_content_type($fullpath);
// Call the API with the media upload, defer so it doesn't immediately return.
$client->setDefer(true);
$request = $service->files->create($file);
// Create a media file upload to represent our upload process.
$media = new Google_Http_MediaFileUpload(
$client,
$request,
$mimeType,
null,
true,
$chunkSizeBytes
);
$media->setFileSize(filesize($fullpath));
// Upload the various chunks. $status will be false until the process is complete.
$status = false;
$handle = fopen($fullpath, "rb");
while (!$status && !feof($handle)) {
$chunk = fread($handle, $chunkSizeBytes);
$status = $media->nextChunk($chunk);
}
// The final value of $status will be the data from the API for the object that has been uploaded.
$result = false;
if($status != false) {
$result = $status;
error_log($result->id);
}
fclose($handle);
$permissions = new Google_Service_Drive_Permission(array(
"role" => "reader",
"type" => "anyone"
));
$setPermission = $service->permissions->create($result->id, $permissions);
Any suggestions on what I'm doing wrong?

Answer 1

I have had the same situation with you. In that case, when the file information is retrieved with $res = $service->files->get($result->id); after the file was uploaded with the resumable upload, the empty object of {} is returned without error. I thought that this is the reason of the issue.
So, I used the following workaround. In this workaround, after the file was uploaded with the resumable upload, I retrieved $client again. By this, $res = $service->files->get($result->id); worked after the file was uploaded. When this is used for your script, please modify as follows.
From:
fclose($handle);
$permissions = new Google_Service_Drive_Permission(array(
"role" => "reader",
"type" => "anyone"
));
$setPermission = $service->permissions->create($result->id, $permissions);
To:
fclose($handle);
$client = getClient(); // <--- Added
$service = new Google_Service_Drive($client); // <--- Added
$permissions = new Google_Service_Drive_Permission(array(
"role" => "reader",
"type" => "anyone"
));
$setPermission = $service->permissions->create($result->id, $permissions);
getClient() is for retrieving $client. So please modify this part for your actual situation.
Note:
This answer supposes that your $client can be created the permissions to the uploaded file. Please be careful this.

Answer 2

$client->setDefer(true); is causing the issue. That's why it works when you create a new instance of Google client.
Another fix might be to do $client->setDefer(false); after uploading the file.
