Im trying to create a Youtube upload script that does not require the end user to login in order to upload a video to my channel. The issue is I can gain the access token but it expires after an hour of being inactive. Also I am unsure where you can get the "refresh_token" from.
So essentially I wish to have this Google API v3 script not require any client side authentication in order to upload video's.
From what I gather from the API documentation at google if I had the "refresh_token" I could renew the token without the need of user interaction required.
Please see below my existing code on the matter.
<?php
$key = json_decode(file_get_contents('the_key.txt'));
require_once 'Client.php';
require_once 'Service/YouTube.php';
session_start();
$OAUTH2_CLIENT_ID = 'YOUR_CLIENT_ID.apps.googleusercontent.com';
$OAUTH2_CLIENT_SECRET = 'YOUR_SECRET_KEY';
$REDIRECT = 'http://example.com/test.php';//Must be exact as setup on google API console
$APPNAME = "Test upload app";
$client = new Google_Client();
$client->setClientId($OAUTH2_CLIENT_ID);
$client->setClientSecret($OAUTH2_CLIENT_SECRET);
$client->setScopes('https://www.googleapis.com/auth/youtube');
$client->setRedirectUri($REDIRECT);
$client->setApplicationName($APPNAME);
$client->setAccessType('offline');
// Define an object that will be used to make all API requests.
$youtube = new Google_Service_YouTube($client);
if (isset($_GET['code'])) {
if (strval($_SESSION['state']) !== strval($_GET['state'])) {
die('The session state did not match.');
}
$client->authenticate($_GET['code']);
$_SESSION['token'] = $client->getAccessToken();
}
if (isset($_SESSION['token'])) {
//if session current save to file updates token key
$client->setAccessToken($_SESSION['token']);
echo '<code>' . $_SESSION['token'] . '</code><br>';
file_put_contents('the_key.txt', $_SESSION['token']);
}
// Check to ensure that the access token was successfully acquired.
if ($client->getAccessToken()) {
if($client->isAccessTokenExpired()) {
echo "Token Expired<br>Attempt Refresh: ";
$client->refreshToken($key->access_token);
//refresh token, now need to update it in session
$_SESSION['access_token']= $client->getAccessToken();
}
$_SESSION['token'] = $client->getAccessToken();

} else {
$state = mt_rand();
$client->setState($state);
$_SESSION['state'] = $state;
$authUrl = $client->createAuthUrl();
$htmlBody = '<h3>Authorization Required</h3><p>You need to <a href="$authUrl">authorise access</a> before proceeding.<p>';
}
?>

If someone can look over this code and tell me what I'm missing would be great.
