Google Drive API every time asking for authentication code - php

Question

I'm using google drive api to upload a file to google drive using php, but it every time asking me for authentication code fof my application.
I have followed the steps given in the URL below
https://developers.google.com/drive/web/quickstart/quickstart-php
My Code:
require_once 'src/Google/autoload.php';
$client = new Google_Client();
// Get your credentials from the console
$client->setClientId('clientid');
$client->setClientSecret('clientsecret');
$client->setRedirectUri('url');
$client->setScopes(array('https://www.googleapis.com/auth/drive'));
$service = new Google_Service_Drive($client);
$authUrl = $client->createAuthUrl();
try{
//Request authorization
print "Please visit:<br/>$authUrl<br/>\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_Service_Drive_DriveFile();
$file->setTitle('document.txt');
$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);
}catch(apiServiceException $e){
echo $e->getMessage();

Answer 1

I have did more debugging for this issue and last i can upload files to google drive using PHP.
But for this we have to authorize the code using manually according to google api
then we will get the refresh token and using that token we can upload file to google drive every time whout asking any key
I have added code here https://rgknowledgebase.wordpress.com/2015/06/05/php-upload-file-to-google-drive/
