Question

i am using google drive file upload code. The following code runs correct in browser. But if i try to do it we error as : fgets() expects parameter 1 to be resource, string given
I have tried many solution but its not working. Please guide me how to use this code for web service to upload file to google drive.

require_once 'google-api-php-client/src/contrib/Google_DriveService.php';
function uploadFile()
{
$client = new Google_Client();
// Get your credentials from the console
$client->setClientId('**********************');
$client->setClientSecret('*********');
$client->setRedirectUri('*********');
$client->setScopes(array('https://www.googleapis.com/auth/drive'));
if(!defined("STDIN")) define("STDIN", "fopen('php://stdin','r')");
$service = new Google_DriveService($client);
$authUrl = $client->createAuthUrl();
//Request authorization
print "Please visit:\n$authUrl\n\n";
print "Please enter the auth code:\n";
$authCode = trim(fgets(STDIN));
//$authCode = trim(file_get_contents(STDIN));
// Exchange authorization code for access token
$accessToken = $client->authenticate($authCode);
$client->setAccessToken($accessToken);
//Insert a file
$file = new Google_DriveFile();
$file->setTitle('Test document');
$file->setDescription('A test document');
$file->setMimeType('text/plain');
$data = file_get_contents('upload.txt');
$createdFile = $service->files->insert($file, array(
'data' => $data,
'mimeType' => 'text/plain',
));
print_r($createdFile);
}

STDIN is a command line instruction and it isn't a direct valid php statement ..
What i did was :
$client = new Google_Client();
// Get your credentials from the console
$client->setClientId('**********************');
$client->setClientSecret('*********');
$client->setRedirectUri('*********');
$client->setScopes(array('https://www.googleapis.com/auth/drive'));
$authUrl = $client->createAuthUrl();
print $authurl
$authCode = ''; // insert the verification code that you get after going to url in $authurl
file_put_contents('token.json', $client->authenticate($authCode));
After executing this much you'll get your authentication info in the json file token.json ... And you can use the following to upload ... :
$service = new Google_DriveService($client);
$client->setAccessToken(file_get_contents('token.json'));
//Insert a file
..... // rest the same
Once you get your json don't run the top codes again ... Just use the token.json everytime to upload/download ....
