Files updates no longer works using the google-api-php-client - php

Question

I have a very small script that uploads and / or update files (wrote this about 1 year ago, borrowed 80% of the lines from the examples)
No major changes in the code since march (using 1.0.0-alpha) but mid-may the file updates stopped working, raising an Internal Server Error , i upgraded to 1.0.4-beta with no success :
PHP Fatal error: Uncaught exception 'Google_Service_Exception' with message 'Error calling PUT https://www.googleapis.com/upload/drive/v2/ [...] (500) Internal Error' in
google-api-php-client-1.0.4-beta/src/Google/Http/REST.php:80
code:
$client->setDefer(true);
$request = $service->files->update($update_id,$file);
$media = new Google_Http_MediaFileUpload(
$client,
$request,
'text/plain',
null,
true,
$chunkSizeBytes
);
$media->setFileSize(filesize($csvfile))
$status = false;
$handle = fopen($csvfile, "rb");
while (!$status && !feof($handle)) {
$chunk = fread($handle, $chunkSizeBytes);
$status = $media->nextChunk($chunk);
}
File inserts (HTTP POST) are still working (using the same code for uploading the chunks)
any ideas ?

Answer 1

I can update a file ( previously created or copied from a template ) with this code :
(...)
require_once 'src/Google/Client.php';
require_once 'src/Google/Service/Oauth2.php';
require_once 'src/Google/Service/Drive.php';
(...)
$client = new Google_Client();
// set scopes ...
(...)
$GDrive_service = new Google_Service_Drive($client);
(...)
// then I set parameters
(...)
$newTitle = $title ;
$newDescription = $description ;
$newMimeType = 'text/csv' ;
$newFileName = $filename ;
$service = $GDrive_service ;
(...)
$updatedFile = updateFile($service, $fileId, $newTitle, $newDescription, $newMimeType, $newFileName, $newRevision) ;
function updateFile($service, $fileId, $newTitle, $newDescription, $newMimeType, $newFileName, $newRevision) {
try {
// First retrieve the file from the API.
$file = $service->files->get($fileId);
// File's new metadata.
$file->setTitle($newTitle);
$file->setDescription($newDescription);
$file->setMimeType($newMimeType);
// File's new content.
$data = file_get_contents($newFileName);
$convert = 'true' ;
$additionalParams = array(
'uploadType' => 'multipart',
'newRevision' => $newRevision,
'data' => $data,
'mimeType' => $newMimeType,
'convert' => $convert,
);
// Send the request to the API.
$updatedFile = $service->files->update($fileId, $file, $additionalParams);
return $updatedFile;
} catch (Exception $e) {
print "An error occurred: " . $e->getMessage();
}
}
(...)
// this is info of the updated file
$fileId = $updatedFile->getId() ;
// link of file
$cF_link = $updatedFile->alternateLink ;
// pdf version
$enllacos = $updatedFile->exportLinks ;
$cF_PDF_link = $enllacos['application/pdf'] ;
(...)
This code is working with the 1.0.5-beta php client
