Youtube api 将youtube api代码版本2迁移到版本3

我在php代码中使用了youtube api版本2。如何快速将代码迁移到版本3？ 我应该获得新的开发者密钥吗？我以前用过谷歌开发者密钥：但现在我无法打开这个页面，我看到502了。那是个错误

我的youtube API 2代码：

require_once("Zend/Gdata/ClientLogin.php");
require_once("Zend/Gdata/HttpClient.php");
require_once("Zend/Gdata/YouTube.php");
require_once("Zend/Gdata/App/HttpException.php");
require_once('Zend/Uri/Http.php');

$authenticationURL = 'https://www.google.com/youtube/accounts/ClientLogin';
$httpClient = Zend_Gdata_ClientLogin::getHttpClient(
    $username = $CFG->videoboard_youtube_email,
    $password = $CFG->videoboard_youtube_password,
    $service = 'youtube',
    $client = null,
    $source = 'VideoBoard',
    $loginToken = null,
    $loginCaptcha = null,
    $authenticationURL);

$yt = new Zend_Gdata_YouTube($httpClient, 'VideoBoard', NULL, $CFG->videoboard_youtube_apikey);

$myVideoEntry = new Zend_Gdata_YouTube_VideoEntry();

$accessControlElement = new Zend_Gdata_App_Extension_Element(
    'yt:accessControl', 'yt', 'http://gdata.youtube.com/schemas/2007', ''
);
$accessControlElement->extensionAttributes = array(
    array(
        'namespaceUri' => '',
        'name' => 'action',
        'value' => 'list'
    ),
    array(
        'namespaceUri' => '',
        'name' => 'permission',
        'value' => 'denied'
    ));

$myVideoEntry->extensionElements = array($accessControlElement);

$filesource = $yt->newMediaFileSource($from->fullpatch);
$filesource->setContentType($data->type);
$filesource->setSlug('slug');
$myVideoEntry->setMediaSource($filesource);

$myVideoEntry->setVideoTitle($from->author);
$myVideoEntry->setVideoDescription($from->author);
$myVideoEntry->setVideoCategory('Education');
$myVideoEntry->SetVideoTags('videoboard');

$uploadUrl = 'http://uploads.gdata.youtube.com/feeds/api/users/default/uploads';

try {
    $newEntry = $yt->insertEntry($myVideoEntry, $uploadUrl, 'Zend_Gdata_YouTube_VideoEntry');
} catch (Zend_Gdata_App_HttpException $httpException) {
    echo $httpException->getRawResponseBody();

    $DB->delete_records('videoboard_process', array('id' => $data->id));
} catch (Zend_Gdata_App_Exception $e) {
    echo $e->getMessage();

    $DB->delete_records('videoboard_process', array('id' => $data->id));
}

$itemidyoutube = $newEntry->getVideoId();

if (!empty($itemidyoutube)){
    $DB->set_field($table, "itemyoutube", $itemidyoutube, array("id" => $item->id));
}

你可以参考这个。通常，错误可能是由windows系统文件损坏引起的。损坏的系统文件条目可能会对计算机的健康构成真正的威胁。此前也有报道称，注册存在临时问题 服务器，建议在
