Youtube refresh token

Recommended Posts

Hi all

 

I am trying to use the YouTube API, and have the site built in such a way that a user deosn't need to authorise access every time.  Below is the code I am using, however I am not getting a refresh token generated.

 

 

<?php
 require '../../library/config.php';
// Call set_include_path() as needed to point to your client library.
set_include_path($shopConfig['url'] . 'fullthrottle/videos/google-api/');
require_once 'google-api/src/Google/Client.php';
require_once 'google-api/src/Google/Service/YouTube.php';
 
/*
 * You can acquire an OAuth 2.0 client ID and client secret from the
 * {{ Google Cloud Console }} <{{ https://cloud.google.com/console }}>
 * For more information about using OAuth 2.0 to access Google APIs, please see:
 * <https://developers.google.com/youtube/v3/guides/authentication>
 * Please ensure that you have enabled the YouTube Data API for your project.
 */
$OAUTH2_CLIENT_ID = $youtube['client_id'];
$OAUTH2_CLIENT_SECRET = $youtube['client_secret'];
$REDIRECT = $shopConfig['url'].'fullthrottle/videos/upload.php';
$APPNAME = $youtube['app_name'];
$ACCESS_TOKEN = $youtube['access_token'];
 
$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'])) {
    $client->setAccessToken($_SESSION['token']);
    //echo '<code>' . $_SESSION['token'] . '</code>';
}
 
// Check to ensure that the access token was successfully acquired.
if ($client->getAccessToken()) {
    try {
        // Call the channels.list method to retrieve information about the
        // currently authenticated user's channel.
        $channelsResponse = $youtube->channels->listChannels('contentDetails', array(
            'mine' => 'true',
        ));
 
        $htmlBody = '';
        foreach ($channelsResponse['items'] as $channel) {
            // Extract the unique playlist ID that identifies the list of videos
            // uploaded to the channel, and then call the playlistItems.list method
            // to retrieve that list.
            $uploadsListId = $channel['contentDetails']['relatedPlaylists']['uploads'];
            //print_r ($channel);

            $playlistItemsResponse = $youtube->playlistItems->listPlaylistItems('snippet', array(
                'playlistId' => $uploadsListId,
                'maxResults' => 50
            ));
 
            $htmlBody .= "<h3>Videos in list $uploadsListId</h3><ul>";
            foreach ($playlistItemsResponse['items'] as $playlistItem) {
            print_r($playlistItem);
                $htmlBody .= sprintf('<li>'. $playlistItem['snippet']['title'].' <img src="'.$playlistItem['snippet']['thumbnails']['high']['url'].'" style="max-width:200px"/>'.$playlistItem['snippet']['description'].'</li>');
            }
            $htmlBody .= '</ul>';
        }
    } catch (Google_ServiceException $e) {
        $htmlBody .= sprintf('<p>A service error occurred: <code>%s</code></p>',
            htmlspecialchars($e->getMessage()));
    } catch (Google_Exception $e) {
        $htmlBody .= sprintf('<p>An client error occurred: <code>%s</code></p>',
            htmlspecialchars($e->getMessage()));
    }
 
    $_SESSION['token'] = $client->getAccessToken();
} else {
    $state = mt_rand();
    $client->setState($state);
    $_SESSION['state'] = $state;
 
    $authUrl = $client->createAuthUrl();
    $htmlBody = <<<END
  <h3>Authorization Required</h3>
  <p>You need to <a href="$authUrl">authorise access</a> before proceeding.<p>
END;
}
?>
 
<!doctype html>
<html>
<head>
    <title>My Uploads</title>
</head>
<body>
<?php echo $htmlBody;?>
</body>
</html>

 

Also do I need to store the access tokens in a database at all for them to be used in the future?

 

Thanks in advance

I have added that to

 

if (isset($_SESSION['token'])) {
    $client->setAccessToken($_SESSION['token']);
    echo '<code>' . $_SESSION['token'] . '</code>';
    $client->getRefreshToken();
//echo '<code>'.$this->token['refresh_token'].'</code>';
}

but I am still not getting a refresh token, and am having to login every time

$client->getRefreshToken() returns the refresh token. You're not doing anything with the return value.

 

From the docs:

/**
* Get the OAuth 2.0 refresh token.
* @return string $refreshToken refresh token or null if not available
*/
public function getRefreshToken()
{
    return $this->getAuth()->getRefreshToken();
}

Simply acquiring the refresh token does nothing on its own. The refresh token is used to "refresh" the access token. Normally in OAuth2, the access token is short-lived and expires quickly, usually in a few hours. You must send the access token in an Authorization header for each request so that the endpoint can authenticate you. When the access token expires, you would then send a different request to refresh it and get a new access token, without having to enter credentials again.
